1m0. INTRODUCTION0m
|
||||
This is a low level graphics library for Linux, originally based on
|
||||
VGAlib 1.2 by Tommy Frandsen. VGAlib supported a number of standard VGA
|
||||
graphics modes, as well as Tseng ET4000 high resolution 256-color
|
||||
modes. As of now, support for many more chipsets has been added. See
|
||||
section 1m4 Overview of supported SVGA chipsets and modes0m
|
||||
|
||||
It supports transparent virtual console switching, that is, you can
|
||||
switch consoles to and from text and graphics mode consoles using
|
||||
alt-[function key]. Also, svgalib corrects most of VGAlib's textmode
|
||||
corruption behaviour by catching 1mSIGSEGV22m, 1mSIGFPE22m, 1mSIGILL22m, and other
|
||||
fatal signals and ensuring that a program is running in the currently
|
||||
visible virtual console before setting a graphics mode.
|
||||
|
||||
Note right here that 1mSIGUSR1 22mand 1mSIGUSR2 22mare used to manage console
|
||||
switching internally in 1msvgalib22m. You can not use them in your pro-
|
||||
grams. If your program needs to use one of those signals, svgalib can
|
||||
be compiled to use other signals, by editing libvga.h
|
||||
|
||||
This version includes code to hunt for a free virtual console on its
|
||||
own in case you are not starting the program from one (but instead over
|
||||
a network or modem login, from within 1mscreen22m(1) or an 1mxterm22m(1)). Pro-
|
||||
vided there is a free console, this succeeds if you are root or if the
|
||||
svgalib calling user own the current console. This is to avoid people
|
||||
not using the console being able to fiddle with it. On graceful exit
|
||||
the program returns to the console from which it was started. Other-
|
||||
wise it remains in text mode at the VC which svgalib allocated to allow
|
||||
you to see any error messages. In any case, any I/O the svgalib makes
|
||||
in text mode (after calling 1mvga_init22m(3)) will also take place at this
|
||||
new console.
|
||||
|
||||
Alas, some games misuse their suid root privilege and run as full root
|
||||
process. svgalib cannot detect this and allows Joe Blow User to open a
|
||||
new VC on the console. If this annoys you, 1mROOT_VC_SHORTCUT 22min 4mMake-0m
|
||||
4mfile.cfg24m allows you to disable allocating a new VC for root (except
|
||||
when he owns the current console) when you compile svgalib. This is the
|
||||
default.
|
||||
|
||||
When the library is used by a program at run-time, first the chipset is
|
||||
detected and the appropriate driver is used. This means that a graphics
|
||||
program will work on any card that is supported by svgalib, if the mode
|
||||
it uses is supported by the chipset driver for that card. The library
|
||||
is upwardly compatible with VGAlib.
|
||||
|
||||
The set of drawing functions provided by svgalib itself is limited
|
||||
(unchanged from VGAlib) and unoptimized; you can however use 1mvga_set-0m
|
||||
1mpage22m(3) and 1mvga_getgraphmem22m(3) (which points to the 64K VGA
|
||||
framebuffer) in a program or graphics library. A fast external frame-
|
||||
buffer graphics library for linear and banked 1, 2, 3 and 4 bytes per
|
||||
pixel modes is included (it also indirectly supports planar VGA modes).
|
||||
It is documented in 1mvgagl22m(7).
|
||||
|
||||
One obvious application of the library is a picture viewer. Several are
|
||||
available, along with animation viewers. See the 1m7. References 22mat the
|
||||
end of this document.
|
||||
|
||||
I have added a simple VGA textmode font restoration utility (1mrestore-0m
|
||||
1mfont22m(1)) which may help if you suffer from XFree86 textmode font cor-
|
||||
ruption. It can also be used to change the textmode font. It comes with
|
||||
some other textmode utilities: 1mrestoretextmode22m(1) (which saves/restores
|
||||
textmode registers), 1mrestorepalette22m(1), and the script 1mtextmode22m(1). If
|
||||
you run the 1msavetextmode22m(1) script to save textmode information to
|
||||
4m/tmp24m, you'll be able to restore textmode by running the 1mtextmode22m(1)
|
||||
script.
|
||||
|
||||
|
||||
1m1. INSTALLATION0m
|
||||
Installation is easy in general but there are many options and things
|
||||
you should keep in mind. This document however assumes that 1msvgalib 22mis
|
||||
already installed.
|
||||
|
||||
If you need information on installation see 4m0-INSTALL24m which comes with
|
||||
the svgalib distribution.
|
||||
|
||||
However, even after installation of the library you might need to con-
|
||||
figure svgalib using the file 4m/etc/vga/libvga.config24m. Checkout section
|
||||
1m4 Overview of supported SVGA chipsets and modes 22mand 1mlibvga.config22m(5)
|
||||
for information.
|
||||
|
||||
|
||||
1m2. HOW TO USE SVGALIB0m
|
||||
For basic svgalib usage (no mouse, no raw keyboard) add 1m#include0m
|
||||
1m<vga.h> 22mat the beginning your program. Use 1mvga_init22m(3) as your first
|
||||
1msvgalib 22mcall. This will give up root privileges right after initializa-
|
||||
tion, making setuid-root binaries relatively safe.
|
||||
|
||||
The function 1mvga_getdefaultmode22m(3) checks the environment variable
|
||||
1mSVGALIB_DEFAULT_MODE 22mfor a default mode, and returns the corresponding
|
||||
mode number. The environment string can either be a mode number or a
|
||||
mode name as in (1mG640x480x222m, 1mG640x480x1622m, 1mG640x480x256 22m, 1mG640x480x32K22m,
|
||||
1mG640x480x64K22m, 1mG640x480x16M22m). As an example, to set the default graph-
|
||||
ics mode to 640x480, 256 colors, use:
|
||||
|
||||
1mexport SVGALIB_DEFAULT_MODE=G640x480x2560m
|
||||
|
||||
on the 1mbash(1) 22mcommand line. If a program needs just a linear VGA/SVGA
|
||||
resolution (as required by 1mvgagl22m(7)), only modes where 1mbytesperpixel 22min
|
||||
the 1mvga_modeinfo 22mstructure returned by 1mvga_getmodeinfo22m(3) is greater or
|
||||
equal to 1 should be accepted (this is 0 for tweaked planar 256-color
|
||||
VGA modes).
|
||||
|
||||
Use 1mvga_setmode(4m22mgraphicsmode24m1m) 22mto set a graphics mode. Use 1mvga_set-0m
|
||||
1mmode(TEXT) 22mto restore textmode before program exit.
|
||||
|
||||
Programs that use svgalib must 1m#include<vga.h>22m; if they also use the
|
||||
external graphics library 1mvgagl22m(7), you must also 1m#include<vgagl.h>22m.
|
||||
Linking must be done with 1m-lvga 22m(and 1m-lvgagl 22mbefore 1m-lvga22m, if 1mvgagl22m(7)
|
||||
is used). You can save binary space by removing the unused chipset
|
||||
drivers in 4mMakefile.cfg24m if you only use specific chipsets. However this
|
||||
reduces the flexibility of svgalib and has a significant effect only
|
||||
when you use the static libraries. You should better use the shared
|
||||
libraries and these will load only the really used parts anyway.
|
||||
|
||||
Functions in the 1mvgagl22m(7) library have the prefix 1mgl_22m. Please see
|
||||
1mvgagl22m(7) for details.
|
||||
|
||||
There are demos with sources available which will also help to get you
|
||||
started, in recomended order of interest: 1mvgatest22m(6), 1mkeytest22m(6),
|
||||
1mmousetest22m(6), 1meventtest22m(6), 1mforktest22m(6), 1mbg_test22m(6), 1mscrolltest22m(6),
|
||||
1mspeedtest22m(6), 1mfun22m(6), 1mspin22m(6), 1mtestlinear22m(6), 1mlineart22m(6), 1mtestgl22m(6),
|
||||
1maccel22m(6), 1mtestaccel22m(6), 1mplane22m(6), and 1mwrapdemo22m(6).
|
||||
|
||||
Debugging your programs will turn out to be rather difficult, because
|
||||
the svgalib application can not restore textmode when it returns to the
|
||||
debugger.
|
||||
|
||||
Happy are the users with a serial terminal, X-station, or another way
|
||||
to log into the machine from network. These can use
|
||||
|
||||
1mtextmode </dev/tty4m22mN0m
|
||||
|
||||
on the console where the program runs and continue.
|
||||
|
||||
However, the 1mvga_flip22m(3) function allows you to switch to textmode by
|
||||
entering a call to it blindly into your debugger when your program
|
||||
stops in graphics mode. 1mvga_flip22m(3) is not very robust though. You
|
||||
shall not call it when svgalib is not yet initialized or in textmode.
|
||||
|
||||
Before continuing your program, you must then call 1mvga_flip22m(3) again to
|
||||
return to graphics mode. If the program will not make any screen
|
||||
accesses or svgalib calls before it returns to the debugger, you can
|
||||
omit that, of course.
|
||||
|
||||
This will only work if your program and the debugger run in the same
|
||||
virtual linux console.

1m4. OVERVIEW OF SUPPORTED SVGA CHIPSETS AND MODES0m
|
||||
1mVGA and compatibles0m
|
||||
320x200x256, and the series of 16-color and non-standard planar 256
|
||||
color modes supported by VGAlib, as well as 720x348x2.
|
||||
|
||||
|
||||
1mALI23010m
|
||||
Supports 640x480x256, 800x600x256, 1024x768x256 SVGA modes
|
||||
|
||||
|
||||
1mAT3D (AT25)0m
|
||||
Also known as Promotion at25. Popular as the 2D part of a voodoo rush
|
||||
card. As of this writing there are a few known problems with this
|
||||
driver. Read below.
|
||||
|
||||
|
||||
1mARK Logic ARK1000PV/2000PV0m
|
||||
Full support, limited RAMDAC support. Only ARK1000PV tested. Supports
|
||||
Clocks and Ramdac lines in config file.
|
||||
|
||||
|
||||
1mATI SVGA (VGA Wonder and friends)0m
|
||||
This is no real driver. I do not support any new modes. However it
|
||||
saves additional card setup and thus allows use of the plain VGA modes
|
||||
even when you are using non standard text modes. It is possible to
|
||||
enforce use of this driver even on ATI Mach32 but not very useful.
|
||||
|
||||
|
||||
1mATI Mach320m
|
||||
The driver by Michael Weller supports all ATI BIOS-defined modes and
|
||||
more... It hits the best out of your card. Some modes may not have
|
||||
nice default timings but it uses the ATI's EEPROM for custom config or
|
||||
allows to specify modes in 1mlibvga.config22m(5). Some problems may occur
|
||||
with quite some third party cards (usually on board) Mach32 based con-
|
||||
trollers as they do not completely conform to the Mach32 data sheets.
|
||||
Check out 1msvgalib.mach3222m(7) (and 1mlibvga.config22m(5)).
|
||||
|
||||
|
||||
1mATI Mach64 (rage)0m
|

1m65554 (usually in laptops).0m
|
||||
This server was written using the SVGALIB patch from Sergio and Angelo
|
||||
Masci as a starting point. This version of the code resembled the XFree
|
||||
server code that was used up to XFree 3.1.2. As such it was incapable
|
||||
of programming the clocks, using linear addressing, Hi-Color, True-
|
||||
Color modes or the hardware acceleration. All of these features have
|
||||
since been added to the code. The 64200 and 64300 chips are unsup-
|
||||
ported, however these chips are very similar to the 6554x chips which
|
||||
are supported.
|
||||
|
||||
|
||||
1mCirrus Logic GD542x/3x0m
|
||||
All the modes, including 256 color, 32K/64K color, 16M color (3 bytes
|
||||
per pixel) and 32-bit pixel 16M color modes (5434). Some bitblt func-
|
||||
tions are supported. The driver doesn't work with mode dumps, but uses
|
||||
a SVGA abstraction with mode timings like the X drivers.
|
||||
|
||||
|
||||
1mGenoa(?) GVGA6400 cards.0m
|
||||
Supported.
|
||||
|
||||
|
||||
1mHercules Stingray 64/Video0m
|
||||
Is supported as an ARK2000PV
|
||||
|
||||
|
||||
1mNV3 driver for the Riva128.0m
|
||||
This driver was written by Matan Ziv-Av and is derived from the XFree86
|
||||
driver by David J. Mckay. It lacks 24bit modes (can the card do them at
|
||||
all?), acceleration support and pageflipping in threeDKit is broken.
|
||||
|
||||
|
||||
1mOak Technologies OTI-037/67/77/870m
|
||||
Driver by Christopher Wiles; includes 32K color modes for OTI-087.
|
||||
|
||||
|
||||
1mS30m
|
||||
The driver is not complete, but should work on a number of cards/RAM-
|
||||
DACs, and 640x480x256 should work on most card. The best support is for
|
||||
a 801/805 with AT&T20C490-compatible RAMDAC, and S3-864 + SDAC. All
|
||||
256/32K/64K/16M works for them (within the bounds of video memory &
|
||||
ramdac restrictions).
|
||||
|
||||
The supported cards include S3 Virge and S3 Trio64 cards.
|
||||
|
||||
None of the acceleration function is supported yet.
|
||||
|
||||
The chip level code should work with the 964/868/968, but most likely
|
||||
the card they come on would use an unsupported ramdac/clock chip. Sup-
|
||||
port for these chips is slowly being added.
|
||||
|
||||
Clocks and Ramdac lines in 1mlibvga.config22m(5) supported.
|
||||
|
||||
The maximum pixel clock (in MHz) of the ramdac can be set using a 1mDac-0m
|
||||
1mspeed 22mline in the config file. A reasonable default is assumed if the
|
||||
1mDacspeed 22mline is omitted. 1mClocks 22mshould be the same as in XFree86.
|
||||
Supported ramdac IDs: 1mSierra32K22m, 1mSC1502522m, 1mSDAC22m, 1mGenDAC22m, 1mATT20C49022m,
|
||||
1mATT20C49822m, 1mIBMRGB52x22m.
|
||||
|
||||
Example:
|
||||
1mClocks 25.175 28.3 40 70 50 75 36 44.9 0 118 77 31.5 110 65 72 93.50m
|
||||
1mRamdac att20c4900m
|
||||
1mDacSpeed 850m
|
||||
|
||||
Also supported, at least in combination with the SC15025/26A ramdac, is
|
||||
the ICD 2061A clock chip. Since it cannot be autodetected you need to
|
||||
define it in the config file using a 1mClockchip 22mline. As there is no way
|
||||
to read the current settings out of the 2061, you have the option to
|
||||
specify the frequency used when switching back to text mode as second
|
||||
argument in the 1mClockchip 22mline.
|
||||
|
||||
This is especially required if your text mode is an 132 column mode,
|
||||
since these modes use a clock from the clock chip, while 80 column
|
||||
modes use a fixed clock of 25 MHz. The text mode frequency defaults to
|
||||
40 MHz, if omitted.
|
||||

1mTrident TVGA 8900C/9000 (and possibly also 8800CS/8900A/B) and also TVGA0m
|
||||
1m94400m
|
||||
Derived from tvgalib by Toomas Losin. TVGA 9440 support by ARK
|
||||
<ark@lhq.com, root@ark.dyn.ml.or>.
|
||||
|
||||
Supports 640x480x256, 800x600x256, 1024x768x256 (interlaced and non-
|
||||
interlaced) Might be useful to add 16-color modes (for those equipped
|
||||
with a 512K TVGA9000) for the 8900 and 9000 cards.
|
||||
|
||||
320x200x{32K, 64K, 16M}, 640x480x{256, 32K, 64K, 16M}, 800x600x{256,
|
||||
32K, 64K, 16M}, 1024x768x{16, 256}, 800x600x{16, 256, 32K, 64K} modes
|
||||
are supported for the TVGA 9440.
|
||||
|
||||
Autodetection can be forced with a:
|
||||
|
||||
1mchipset TVGA 4m22mmemory24m 4mflags0m
|
||||
|
||||
line in the config file.
|
||||
|
||||
4mmemory24m is the amount of VGA memory in KB, 4mflags24m is composed of three
|
||||
bits:
|
||||
|
||||
1mbit2 = false, bit1 = false0m
|
||||
force 8900.
|
||||
|
||||
1mbit2 = false, bit1 = true0m
|
||||
force 9440.
|
||||
|
||||
1mbit2 = true, bit1 = false0m
|
||||
force 9680.
|
||||
|
||||
1mbit0 = true0m
|
||||
force noninterlaced.
|
||||
|
||||
1mbit0 = false0m
|
||||
force interlaced which only matters on 8900's with at
|
||||
least 1M since there is no 512K interlaced mode on the
|
||||
8900 or any of the other cards.
|
||||
|
||||
|
||||
1mTseng ET4000/ET4000W32(i/p)0m
|
||||
Derived from VGAlib; not the same register values. ET4000 register
|
||||
values are not compatible; see 1msvgalib.et400022m(7).
|
||||
|
||||
Make sure the colors are right in hicolor mode; the vgatest program
|
||||
should draw the same color bars for 256 and hicolor modes (the DAC type
|
||||
is defined at compilation in 4met4000.regs24m or the dynamic registers
|
||||
file). ET4000/W32 based cards usually have an AT&T or Sierra 15025/6
|
||||
DAC. With recent W32p based cards, you might have some luck with the
|
||||
AT&T DAC type. If the high resolution modes don't work, you can try
|
||||
dumping the registers in DOS using the program in the 4met4000/24m directory
|
||||
and putting them in a file (4m/etc/vga/libvga.et400024m is parsed at runtime
|
||||
if 1mDYNAMIC 22mis defined in 4mMakefile.cfg24m at compilation (this is
|
||||
default)).
|
||||
|
||||
Supported modes are 640x480x256, 800x600x256, 1024x768x256,
|
||||
640x480x32K, 800x600x32K, 640x480x16M, etc.
|
||||
|
||||
Reports of ET4000/W32i/p functionality are welcome.
|
||||
|
||||
There may be a problem with the way the hicolor DAC register is han-
|
||||
dled; dumped registers may use one of two timing methods, with the
|
||||
value written to the register for a particular DAC for a hicolor mode
|
||||
(in vgahico.c) being correct for just one of the these methods. As a
|
||||
consequence some dumped resolutions may work while others don't.
|
||||
|
||||
|
||||
1mTseng ET60000m
|
||||
Most modes of which the card is capable are supported. The 8 15 16 24
|
||||
and 32 bit modes are supported.
|
||||
|
||||
The ET6000 has a built in DAC and there is no problem coming from that
|
||||
area. The ET6000 is capable of acceleration, but this as well as
|
||||
sprites are not yet implemented in the driver.
|
||||
|
||||
The driver now uses modelines in libvga.config for user defined modes.
|
||||
It is sometimes useful to add a modeline for a resolution which does
|
||||
not display well. For example, the G400x600 is too far to the right of
|
||||
the screen using standard modes. This is corrected by including in
|
||||
1mlibvga.config 22mthe line
|
||||
|
||||
Modeline "400x600@72" 25.000 400 440 488 520 600 639 644 666
|
||||
|
||||
More examples are given below.
|
||||
|
||||
This driver was provided by Don Secrest.

|
||||
Please read README.vesa and README.lrmi in doc subdirectory of the
|
||||
standard distribution.
|
||||
|
||||
Go figure! I turned off autodetection in the release, as a broken bios
|
||||
will be called too, maybe crashing the machine. Enforce 1mVESA 22mmode by
|
||||
putting a 1mchipset VESA 22min the end of your 4mlibvga.config24m(5).
|
||||
|
||||
Note that it will leave protected mode and call the cards bios opening
|
||||
the door to many hazards.

|
||||
This section contains detailed information by the authors on certain
|
||||
chipsets.
|
||||
|
||||
|
||||
1mAT3D (AT25)0m
|
||||
Also known as Promotion at25. Popular as the 2D part of a voodoo rush
|
||||
card.
|
||||
|
||||
I have written a driver for this chipset, based on the XF86 driver for
|
||||
this chipset.
|
||||
|
||||
The programs that work with this driver include all the programs in the
|
||||
demos directory, zgv and dvisvga (tmview).
|
||||
|
||||
I believe it should be easy to make it work on AT24, AT6422.

|
||||
Please see 1msvgalib.mach3222m(7).
|
||||
|
||||
|
||||
1mATI Mach640m
|
||||
The rage.c driver works only on mach64 based cards with internal DAC.
|
||||
The driver might misdetect the base frequency the card uses, so if when
|
||||
setting any svgalib modes the screen blanks, or complains about out of
|
||||
bound freqencies, or the display is unsynced, then try adding the
|
||||
option 1mRageDoubleClock 22mto the config file.

|

1mTseng ET60000m
|
||||
I have only 2 Mbytes of memory on my ET6000 card, so I am not able to
|
||||
get all possible modes running. I haven't even tried to do all of the
|
||||
modes which I am capable of doing, but I am confident that I can manage
|
||||
more modes when I have time. I have enough modes working to make the
|
||||
card useful, so I felt it was worth while to add the driver to svgalib
|
||||
now.
|
||||
|
||||
Linear graphics is working on this card, both with and without BACK-
|
||||
GROUND enabled, and vga_runinbackground works.
|
||||
|
||||
I decided it was best to quit working on more modes and try to get
|
||||
acceleration and sprites working.
|
||||
|
||||
My et6000 card is on a PCI bus. The card will run on a vesa bus, but
|
||||
since I don't have one on my machine I couldn't develop vesa bus han-
|
||||
dling. I quit if the bus is a vesa bus.
|
||||
|
||||
I check for an et6000 card, which can be unequivocally identified. The
|
||||
et4000 driver does not properly identify et4000 cards. It thinks the
|
||||
et6000 card is an et4000, but can only run it in vga modes.
|
||||
|
||||
I have found the following four modelines to be useful in 1mlibvga.config0m
|
||||
or in 1m~/.svgalibrc 22mfor proper display of some modes.
|
||||

1mOak Technologies OTI-037/67/77/870m
|
||||
First a few comments of me (Michael Weller <eowmob@exp-math.uni-
|
||||
essen.de>):
|
||||
|
||||
As of this writing (1.2.8) fixes were made to the oak driver by Frodo
|
||||
Looijaard <frodol@dds.nl> to reenable OTI-067 support. It is unknown
|
||||
right now if they might have broken OTI-087 support. The author of the
|
||||
'87 support Christopher Wiles <wileyc@moscow.com> owns no longer an
|
||||
OTI-087 card and can thus no longer give optimal support to this
|
||||
driver. Thus you might be better off contacting me or Frodo for ques-
|
||||
tions. If you are a knowledgable OTI-087 user and experience problems
|
||||
you are welcome to provide fixes. No user of a OTI-087 is currently
|
||||
known to me, so if you are able to fix problems with the driver please
|
||||
do so (and contact me) as noone else can.
|
||||
|
||||
Michael.
|
||||
|
||||
Now back to the original Oak information:
|
||||
|
||||
The original OTI driver, which supported the OTI-067/77 at 640x480x256,
|
||||
has been augmented with the following features:
|
||||
|
||||
|
||||
1m1) 22mSupported resolutions/colors have been expanded to 640x480x32K,
|
||||
800x600x256/32K, 1024x768x256, and 1280x1024x16.
|
||||
|
||||
1m2) 22mThe OTI-087 (all variants) is now supported. Video memory is
|
||||
correctly recognized.
|
||||
|
||||
|
||||
The driver as it exists now is somewhat schizoid. As the '87 incorpo-
|
||||
rates a completely different set of extended registers, I found it nec-
|
||||
essary to split its routines from the others. Further, I did not have
|
||||
access to either a '67 or a '77 for testing the new resolutions. If
|
||||
using them causes your monitor/video card to fry, your dog to bite you,
|
||||
and so forth, I warned you. The driver works on my '87, and that's all
|
||||
I guarantee. Period.
|
||||
|
||||
Heh. Now, if someone wants to try them out ... let me know if they
|
||||
work.
|
||||
|
||||
New from last release:
|
||||
|
||||
32K modes now work for 640x480 and 800x600. I found that the Sierra
|
||||
DAC information in VGADOC3.ZIP is, well, wrong. But, then again, the
|
||||
information for the '87 was wrong also.
|
||||
|
||||
64K modes 1mdo not 22mwork. I can't even get Oak's BIOS to enter those
|
||||
modes.
|
||||
|
||||
I have included a 1280x1024x16 mode, but I haven't tested it. My moni-
|
||||
tor can't handle that resolution. According to the documentation, with
|
||||
2 megs the '87 should be able to do an interlaced 1280x1024x256 ...
|
||||
again, I couldn't get the BIOS to do the mode. I haven't 2 megs any-
|
||||
way, so there it sits.
|
||||
|
||||
I have included routines for entering and leaving linear mode. They
|
||||
1mshould 22mwork, but they don't. It looks like a pointer to the frame
|
||||
buffer is not being passed to SVGALIB. I've been fighting with this
|
||||
one for a month. If anyone wants to play with this, let me know if it
|
||||
can be make to work. I've got exams that I need to pass.
|
||||
|
||||
Tidbit: I pulled the extended register info out of the video BIOS.
|
||||
When the information thus obtained failed to work, I procured the
|
||||
OTI-087 data book. It appears that Oak's video BIOS sets various modes

|
||||
I think the ability to use a VGA/SVGA graphics resolution in one vir-
|
||||
tual console, and being able to switch to any other virtual console
|
||||
and back makes a fairly useful implementation of graphics modes in the
|
||||
Linux console.
|
||||
|
||||
Programs that use 1msvgalib 22mmust be setuid root. I don't know how desir-
|
||||
able it is to have this changed; direct port access can hardly be done
|
||||
without. Root privileges can now be given up right after initializa-
|
||||
tion. I noticed some unimplemented stuff in the kernel header files
|
||||
that may be useful, although doing all register I/O via the kernel
|
||||
would incur a significant context-switching overhead. An alternative
|
||||
might be to have a pseudo 4m/dev/vga24m device that yields the required per-
|
||||
missions when opened, the device being readable by programs in group
|
||||
vga.
|
||||
|
||||
It is important that textmode is restored properly and reliably; it is
|
||||
fairly reliable at the moment, but fast console switching back and
|
||||
forth between two consoles running graphics can give problems. Wild
|
||||
virtual console switching also sometimes corrupts the contents of the
|
||||
textmode screen buffer (not the textmode registers or font). Also if a
|
||||
program crashes it may write into the area where the saved textmode
|
||||
registers are stored, causing textmode not be restored correctly. It
|
||||
would be a good idea to somehow store this information in a 'safe' area
|
||||
(say a kernel buffer). Note that the 1mvga_safety_fork22m(3) thing has the
|
||||
same idea.
|
||||
|
||||
Currently, programs that are in graphics mode are suspended while not
|
||||
in the current virtual console. Would it be a good idea to let them run
|
||||
in the background, virtualizing framebuffer actions (this should not be
|
||||
too hard for linear banked SVGA modes)? It would be nice to have, say,
|
||||
a raytracer with a real-time display run in the background (although
|
||||
just using a separate real-time viewing program is much more elegant).
|
||||
|
||||
Anyone wanting to rewrite it all in a cleaner way (something with load-
|
||||
able kernel modules shouldn't hurt performance with linear frame-
|
||||
buffer/vgagl type applications) is encouraged.
|
||||
|
||||
Also, if anyone feels really strongly about a low-resource and true-
|
||||
color supporting graphical window environment with cut-and-paste, I
|
||||
believe it would be surprisingly little work to come up with a simple
|
||||
but very useful client-server system with shmem, the most useful appli-
|
||||
cations being fairly trivial to write (e.g. shell window, bitmap
|
||||
viewer). And many X apps would port trivially.
|
||||
|
||||
This is old information, please be sure to read 1msvgalib.faq22m(7) if you
|
||||
are interested in further goals.

|
||||
The latest version of svgalib can be found on 4msunsite.unc.edu24m in
|
||||
4m/pub/Linux/libs/graphics24m or 4mtsx-11.mit.edu24m in 4m/pub/linux/sources/libs0m
|
||||
as 4msvgalib-X.X.X.tar.gz24m. As of this writing the latest version is
|
||||
4msvgalib-1.4.1.tar.gz24m. There are countless mirrors of these ftp servers
|
||||
in the world. Certainly a server close to you will carry it.
|
||||
|
||||
The original VGAlib is on 4mtsx-11.mit.edu24m,
|
||||
4mpub/linux/sources/libs/vgalib12.tar.Z24m. 4mtvgalib-1.0.tar.Z24m is in the
|
||||
same directory.
|
||||
|
||||
SLS has long been distributing an old version of VGAlib. Slackware
|
||||
keeps a fairly up-to-date version of svgalib, but it may be installed
|
||||
in different directories from what svgalib likes to do by default. The
|
||||
current svgalib install tries to remove most of this. It also removes
|
||||
4m/usr/bin/setmclk24m and 4m/usr/bin/convfont24m, which is a security risk if
|
||||
setuid-root. Actually the recent makefiles try to do a really good job
|
||||
to cleanup the mess which some distributions make.
|
||||
|
||||
If you want to recompile the a.out shared library, you will need the
|
||||
DLL 'tools' package (found on 4mtsx-11.mit.edu24m, 4mGCC24m dir). To make it
|
||||
work with recent ELF compiler's you actually need to hand patch it. You
|
||||
should probably not try to compile it. Compiling the ELF library is
|
||||
deadly simple.
|
||||
|
||||
And here is a list of other references which is horribly outdated.
|
||||
There are many more svgalib applications as well as the directories
|
||||
might have changed. However, these will give you a start point and
|
||||
names to hunt for on CD's or in ftp archives.

In the vga directory of the 1mSIMTEL MSDOS 22mcollection, there is a package
|

Mitch D'Souza has written font functions that work in 16 color modes
|
||||
and can use VGA textmode (codepage format) fonts; these can be found in
|
||||
his 1mg3fax 22mpackage in 4msunsite.unc.edu24m. These functions may go into a
|
||||
later version of 1msvgalib22m.

1m8. KNOWN BUGS0m
|
||||
This section is most probably outdated, none of these problems are no
|
||||
longer reported.
|
||||
|
||||
Using a 132 column textmode may cause graphics modes to fail. Try using
|
||||
something like 80x28.
|
||||
|
||||
The console switching doesn't preserve some registers that may be used
|
||||
to draw in planar VGA modes.
|
||||
|
||||
Wild console switching can cause the text screen to be corrupted, espe-
|
||||
cially when switching between two graphics consoles.
|
||||
|
||||
On ET4000, having run XFree86 may cause high resolution modes to fail
|
||||
(this is more XFree86's fault).
|
||||
|
||||
The Trident probing routine in the XFree86 server may cause standard
|
||||
VGA modes to fail after exiting X on a Cirrus. Try putting a 'Chipset'
|
||||
line in your Xconfig to avoid the Trident probe, or use the link kit to
|
||||
build a server without the Trident driver. Saving and restoring the
|
||||
textmode registers with savetextmode/textmode (restoretextmode) should
|
||||
also work. [Note: svgalib now resets the particular extended register,
|
||||
but only if the Cirrus driver is used (i.e. the chipset is not forced
|
||||
to VGA)] [This is fixed in XFree86 v2.1]
|
||||
|
||||
Some Paradise VGA cards may not work even in standard VGA modes. Can
|
||||
anyone confirm this?
|
||||
|
||||
Piping data into a graphics program has problems. I am not sure why. A
|
||||
pity, since zcatting a 5Mb FLC file into flip on a 4Mb machine would be
|
||||
fun.
|
||||
|
||||
The 1mtseng3.exe 22mDOS program include as source in the svgalib distribu-
|
||||
tion doesn't recognize any modes on some ET4000 cards. Also ET4000
|
||||
cards with a Acumos/Cirrus DAC may only work correctly in 64K color
|
||||
mode.

This is an _alpha_ release. Don't use it if you are not interested in
|
||||
svgalib development.
|
||||
|
||||
Program using svgalib 1.9.0 or later don't need root provoleges (suid
|
||||
root). They do need access to /dev/svga, which is a char device
|
||||
with major 209 and minor 0.
|
||||
The module svgalib_helper need also be inserted.
|
||||
|
||||
To make the devices, and the module (kernel 2.4 or newer), change to directory
|
||||
kernel/svgalib_helper, and type make install.
|
||||
|
||||
There is a compile time option to return to old behaviour, of using root
|
||||
privileges to access /dev/mem, instead of svgalib helper. To compile for this
|
||||
select the NO_HELPER option in Makefile.cfg.

/*
|
||||
Animation/smooth scrolling demo, uses Mode X/page flipping and
|
||||
linear virtual screen in system memory.
|
||||
|
||||
First method copies window to page-flipped Mode X-style video memory
|
||||
for scrolling.
|
||||
Linear addressing, and page flipping (no shearing) and triple
|
||||
buffering, but relatively slow.
|
||||
|
||||
Second method uses Mode X-style hardware scrolling.
|
||||
Limited logical screen size, page flipping if no scrolling, tricky and
|
||||
slow animation, scrolling fast (page flipping with scrolling is very
|
||||
tricky).
|
||||
|
||||
Third method copies window to linear "Mode 13h" video memory.
|
||||
Linear addressing, no page flipping (scrolling looks bad), speed
|
||||
depends on bus (fast on a good ISA card; very fast on VLB).
|
||||
Some SVGA cards can support page-flipping in linear 320x200x256.
|
||||
|
||||
Adding animated objects is trivial with the virtual screen methods (1
|
||||
and 3).

This graphical test program was originally written by Jason Lyons and
|
||||
later hacked to bits by Eric Sharkey, but this program would not be
|
||||
possible without Brett's efforts. Be sure to thank him!
|
||||
|
||||
The original code for the SpaceOrb in Unix/Linux was written by Brett Viren
|
||||
(Brett.Viren@sunysb.edu) on his free time (ie, not when on the pay
|
||||
clock of SUNY@Stony Brook). Do with it what you will, as long as
|
||||
you abide by the GPL.
|
||||
|
||||
I think by now all of Brett's code has been removed from this demo
|
||||
and incorporated into svgalib itself, but he's still responsible for
|
||||
starting this whole thing.

|
||||
0. Introduction
|
||||
This is a low level graphics library for Linux, based on VGAlib 1.2 by
|
||||
Tommy Frandsen. VGAlib supported a number of standard VGA graphics
|
||||
modes, as well as Tseng ET4000 high resolution 256-color modes.
|
||||
Nowadays support for even more hardware is given. For details on
|
||||
supported chipsets, see the file 0-README which is equal to man 7
|
||||
svgalib (when svgalib is installed).
|
||||
|
||||
It supports transparent virtual console switching, that is, you can
|
||||
switch consoles to and from text and graphics mode consoles using
|
||||
alt-[function key]. Also, svgalib corrects most of VGAlib's textmode
|
||||
corruption behaviour by catching SIGSEGV, SIGFPE and SIGILL, and
|
||||
ensuring that a program is running in the currently visible virtual
|
||||
console before setting a graphics mode. Svgalib uses SIGUSR1 and SIGUSR2
|
||||
internally to do so.
|
||||
|
||||
When the library is first used by a program at run-time, the chipset is
|
||||
detected and the appropriate driver is used. This means that a graphics
|
||||
program will work on any card that is supported by svgalib, if the mode
|
||||
it uses is supported by the chipset driver for that card. The library
|
||||
is upwardly compatible with VGAlib.
|
||||
|
||||
The set of drawing functions provided by svgalib itself is limited
|
||||
(mostly unchanged from VGAlib) and unoptimized; you can however use
|
||||
vga_setpage and graph_mem (which points to the 64K VGA framebuffer) in
|
||||
a program or graphics library. A fast external framebuffer graphics
|
||||
library for linear and banked 1, 2, 3 and 4 bytes per pixel modes is
|
||||
included (it also indirectly supports planar VGA modes). See 'man 7
|
||||
vgagl' for details.
|
||||
|
||||
One obvious application of the library is a picture viewer. Several are
|
||||
available, along with animation viewers. See the references at the end
|
||||
of 0-README.
|
||||
|
||||
I have added a simple VGA textmode font restoration utility
|
||||
(restorefont) which may help if you suffer from XFree86 textmode font
|
||||
corruption. It can also be used to change the textmode font. It's in
|
||||
the utils/ directory, along with a README and some other textmode
|
||||
utilities: restoretextmode (which saves/restores textmode registers),
|
||||
restorepalette, and the script textmode. If you run the savetextmode
|
||||
script to save textmode information to /tmp, you'll be able to restore
|
||||
textmode by running the textmode script.
|
||||
|
||||
If you have an ET4000 card, you should read the 0-README in the et4000/
|
||||
directory. You will probably want to replace the ET4000 registers.
|
||||
|
||||
1. Directories
|
||||
doc/ README's and man pages. See the 0-README in this
|
||||
directory for info on how to read these man pages
|
||||
without installing svgalib and how to produce nice
|
||||
printouts.

||||

|
||||
|
||||
I welcome any questions, comments, suggestions, bug-reports, etc.
|
||||
|
||||
The source code is rather a mess, but there's hope. The new XFree86-style
|
||||
driver interface (used by the Cirrus and S3 drivers) and kernel module
|
||||
graphics that some are experimenting with should provide some momentum.

2. Installation
|
||||
If you are happy with the configuration in 'Makefile.cfg' which means
|
||||
that you want to install an ELF shared library and probably an a.out
|
||||
shared library for support of some old binaries (and if the svgalib tar
|
||||
file you got already contains such an precompiled a.out shared library)
|
||||
just running
|
||||
|
||||
make install
|
||||
|
||||
as root should take care of proper installation. After installation,
|
||||
you MUST edit /etc/vga/libvga.config to set the monitor and mouse type.
|
||||
Depending on your hardware, other setup might be required. Checkout
|
||||
'man 7 svgalib' for details after you installed svgalib (or see
|
||||
doc/0-README)
|
||||
|
||||
It is a good idea to read and check the configurable section of
|
||||
Makefile.cfg nevertheless, even if you don't think you have to. Also,
|
||||
if your are using GLIBC you have to uncomment the definition of
|
||||
USEGLIBC in Makefile.cfg as glibc is not completely compatible to the
|
||||
linux libc (at least at compile time).
|
||||
|
||||
Let me rephrase this: YOU MUST COMPILE AND INSTALL AS ROOT.
|
||||
If you don't nothing bad will happen during compilation, but certain
|
||||
tools won't be able to become SETUID ROOT which is required for
|
||||
proper operation.
|
||||
|
||||
In case you change anything in 'Makefile.cfg' which does not just control
|
||||
which parts to install and where, you *MUST* issue a 'make clean' prior to
|
||||
'make install' to remove any already compiled objects and force complete
|
||||
recompilation.
|
||||
|
||||
Edit Makefile.cfg to change installation paths and to select the parts
|
||||
that should be installed.
|
||||
|
||||
If you have an ET4000 card, read 'man 7 svgalib.et4000' and copy the
|
||||
appropriate register file to et4000.regs. Remember to set the DAC type.
|
||||
|
||||
The default behaviour is the following:
|
||||
|
||||
Shared libraries are installed in /lib and /usr/local/lib, header files
|
||||
in /usr/local/include (any old header files in /usr/include are
|
||||
removed). In the Slackware distribution the linkable libraries are in
|
||||
/usr/lib, and the utilities in /usr/bin; these are now removed by 'make
|
||||
install'. Until now just doing make install with Slackware might have
|
||||
produced duplicate binaries, but fortunately the newer version in
|
||||
/usr/local/* would have taken precedence in use.
|
||||
|
||||
The et4000 registers (et4000.regs) are installed as
|
||||
/etc/vga/libvga.et4000, but only if this file does not exit yet. The
|
||||
same goes for the configuration file, libvga.config.
|
||||
|
||||
Textmode utilities are installed in /usr/local/bin. These are
|
||||
restorefont, runx, restorepalette, dumpreg, restoretextmode, textmode,
|
||||
savetextmode, fix132x43, and mode3.
|
||||
|
||||
If you change Makefile.cfg to install the static libraries, static
|
||||
libraries are compiled, and installed in /usr/local/lib. Note that you
|
||||
do not need to do this; the shared library is enough.
|
||||
|
||||
If you now run 'make demoprogs', the demo programs are created in the
|
||||
demos/ and threeDKit/ directory. If you
|
||||
|
||||
You can remove previously installed files (not the et4000 registers and
|
||||
config file and manual pages) with 'make uninstall'.
|
||||
|
||||
In 1.28 the makefiles were changed. With minimal effort you can compile
|
||||
it from a separate (even read-only) source tree. Just make a copy of
|
||||
Makefile and Makefile.cfg into a writable dir, and change srcdir (or
|
||||
override from environment) to the directory where the source code is.
|
||||
|
||||
This feature, as well as the code for ELF compilation was kindly
|
||||
contributed by Stephen Lee <sl14@crux1.cit.cornell.edu>.
|
||||
|
||||
`make static' compiles a static version of svgalib. It is not
|
||||
automatically installed by default but you can enable that from
|
||||
Makefile.cfg. Note though, that if you specify installation of the static
|
||||
libraries in 'Makefile.cfg' a simple 'make install' will compile the
|
||||
static library first.
|
||||
|
||||
If you do not configure Makefile.cfg to install the shared libs, the
|
||||
demoprogs and utilities are linked against the new static lib
|
||||
(regardless of one already installed). However, the static libraries are
|
||||
not build automatically then. You must issue a 'make static' first.
|
||||
|
||||
Building elf or a.out shared libraries can easily be configured in the
|
||||
Makefile.cfg. Be sure to issue a `make clean' after changing the
|
||||
TARGET_FORMAT setting.
|
||||
|
||||
If you specified elf, `make install' will compile the shared libs as
|
||||
they don't come pre-built. This is nothing to worry about. Compilation
|
||||
is easy and will not use any user action.
|
||||
|
||||
This is not true for a.out and there is a special hack in the makefiles
|
||||
for this. As svgalib is distributed there is no attempt to recompile the
|
||||
a.out sharedlibs. Prebuild images are already included.
|
||||
|
||||
If you have the required tools-* installed and if you made patches (or
|
||||
just feel like recompiling) issue a `make clean' and `make shared' to
|
||||
enforce recompiling of the a.out sharedlibs (from then on even a make
|
||||
install will update the shared library if sources changed). Issue `make
|
||||
distclean' after a `make shared' to fall back to the distribution
|
||||
behaviour.
|
||||
|
||||
However, getting the right tools becomes more and more complicated as
|
||||
it gets less important to give a.out support. Right now you even have to
|
||||
hand patch the last tools-* release to make it usuable with current
|
||||
compilers. In general I discourage trying to compile the a.out libs.
|
||||
Just use the images that come with svgalib.
|
||||
|
||||
3. SVGALib port to ALPHA AXP hardware
|
||||
David Mosberger-Tang <davidm@azstarnet.com> contributed patches to make
|
||||
SVGALib run on Linux/Alpha namely APECS-based and low-cost PCI boards.
|
||||
|
||||
It is known to run with #9 GXE (but all S3-based graphic cards should
|
||||
work if they are supported). He wrote a patch to make SVGALib run on
|
||||
Jensen boards. They own EISA slots instead of PCI slots and can not map
|
||||
video memory as a continous frame buffer. Use this patch with extreme
|
||||
care (do sync disks before starting compiled software for the first
|
||||
time!). He also recommends using SVGATextMode in combination with
|
||||
SVGALib-based software otherwise the library crunches the font
|
||||
(although the system should not crash). Here is a list of what is not
|
||||
supported yet:
|
||||
|
||||
- vc-switching (due to lack of some signals supported by current ALPHA
|
||||
kernels but this could be fixed now [He used a 1.3.28 to test])
|
||||
- font restoring without SVGATextMode (He still works on it)
|
||||
- clearing screen in mode 320x200x256
|
||||
- vgagl (will never be ported by me because he thinks it is too much work
|
||||
and useless in the end)
|
||||
|
||||
He tested his patch with an ELSA Winner 1000 but it should even work on
|
||||
other cards (He recommends to always sync disks, it saves a lot of time
|
||||
and sweat :-) ).
|
||||
|
||||
If you compile it on a machine where __alpha__ is defined, you should
|
||||
have configured your kernel correctly once. This is due to the fact
|
||||
that he saw no other possibility to determine the type of ALPHA AXP
|
||||
hardware you use. During kernel configuration your are asked which
|
||||
architecture you want to compile it for.
|
||||
|
||||
Also important: you must have the right libc compiled for your board
|
||||
hardware. This is due to the I/O functions in libc. They need to be
|
||||
compiled especially for your Alpha board. Have a look at
|
||||
ftp.azstarnet.com for precompiled libc's (although this is not very
|
||||
reliable, most of the libc-packages are sources).
|
||||
|
||||
Note that he feels __not__ responsible for damage to your hardware when
|
||||
using this software. If you encounter any problems that refer to
|
||||
Jensen-type hardware you can send an email to me:
|
||||
|
||||
If you encounter any problems that refer to Jensen-type hardware you
|
||||
can send an email to:
|
||||
Stephan Kanthak <kanthak@i6.informatik.rwth-aachen.de>
|
||||
|
||||
Here are some additional comments Michael Weller wrote on the first
|
||||
ALPHA patches from David Mosberger-Tang:
|
||||
|
||||
No reports of other hardware working or not exist yet. This is REAL
|
||||
ALPHA software. I don't know any installation details. In theory you
|
||||
just recompile it out of the box (When you are using Linux/Alpha you
|
||||
are a hacker and should be able to create a shared lib w/o problems). I
|
||||
don't know any details, in case of problems please contact David.
|
||||
|
||||
From what I saw you might have to use static libs. That's no real
|
||||
problem, a simple 'make static' will create a static lib.
|
||||
|
||||
The background mode is said not to work on Dec-ALPHA, so you better
|
||||
disable it in Makefile.cfg

This file contains some talk about what is involved with a good
|
||||
register-level graphics driver interface. This is an old file,
|
||||
you might also consider reading 'man 7 svgalib.faq'
|
||||
|
||||
Section 1: Mode Setting
|
||||
|
||||
The following describes what happens during a mode set.
|
||||
|
||||
A request is made for a mode with given width, height, and color
|
||||
resolution. Optionally the request can specify a specific pixel size,
|
||||
scanline offset (line width), and pixel size (e.g. 3 vs. 4 pixels for
|
||||
24-bit color modes), otherwise the driver chooses defaults for these
|
||||
properties. It is the intention that requests for resolutions that don't
|
||||
match an availabe mode timing can still be honoured by choosing a higher
|
||||
resolution (for example, 700x500 is requested and 800x600 timing is
|
||||
programmed). The scanline offset should ensure correct drawing of
|
||||
graphics.
|
||||
|
||||
The user-level driver tries to match the requested mode properties with
|
||||
either fixed modes defined by the selected kernel module driver, or with a
|
||||
flexible mode timing if the selected kernel module driver supports mode
|
||||
timing. In the case of fixed modes, the user-level driver must ask the
|
||||
kernel driver about the supported fixed modes, and in the case of mode
|
||||
timings, the user-level driver must ask the kernel driver about physical
|
||||
limits such as the amount of video memory, maximum pixel clocks for each
|
||||
pixel size, range and mapping of horizontal timing parameters, and the
|
||||
available pixel clock frequencies. In both cases, modes/timings that fall
|
||||
outside of the configured monitor specs (probably stored in a file in
|
||||
/etc) will not be selected. In the case of flexible mode timings, the
|
||||
highest refresh timing that is possible will be selected.
|
||||
|
||||
Once a mode timing or fixed mode is selected, the kernel module driver is
|
||||
requested to set the mode on the hardware. A mode state is defined which
|
||||
is a collection of VGA and driver-specific extended register values (byte
|
||||
values) that describes the mode that the video card is set to. During the
|
||||
mode set proper, the following actions are performed:
|
||||
|
||||
1. The registers values that make up the state are read from the video
|
||||
card and stored in a state in system memory (this is the state of
|
||||
the video card before the mode set).
|
||||
|
||||
2. An initialization function modifies the values in the state according
|
||||
to the requested mode. Nothing is written to the card; only the state
|
||||
in system memory is changed.
|
||||
|
||||
3. The actual mode set on the hardware is performed by writing the values
|
||||
in the state to the corresponding registers on the video card.
|
||||
|
||||
A special case is VGA-compatible textmode state, which would normally be
|
||||
active at the time of a graphics mode set. This mode cannot be initialized
|
||||
in the way of (2) above. Instead, the mode is saved using (1), and the
|
||||
resulting state is restored using (3) when textmode needs to be restored.
|
||||
|
||||
Another special case is the setting of a mode for which (1) and (2) have
|
||||
already been performed, and the resulting state has been saved. In this
|
||||
case the mode can be set accomplished by just (3), provided that certain
|
||||
hardware-specific settings on the card have not been changed in the time
|
||||
between (1) and (3) (this would normally be the case).
|
||||
|
||||
When a VT switch away from a graphics modes happens, the current hardware
|
||||
state should be saved, instead of the initialized mode state, since an
|
||||
application can have changed it (banking, displaystart, accelerator state
|
||||
etc.). This is subject to all the extended registers being readable, which
|
||||
may be a problem with some cards (note that for simple mode setting
|
||||
followed by textmode restoration, this is not a problem since the mode
|
||||
initialization overwrites most of the delicate extended registers, and the
|
||||
saved textmode state is largely VGA registers, and doesn't deal with
|
||||
delicate extended registers). A possible solution would be to have
|
||||
functions that save and restore or re-initialize the 'drawing' state,
|
||||
which would include banking, displaystart and accelerator registers. Upon
|
||||
VT switching back, the mode initialization function would be used followed
|
||||
by the restoring of the saved drawing state.
|
||||
|
||||
Section 2: What should be in the kernel driver.
|
||||
|
||||
A decision that has to be made is whether all chipset specific settings
|
||||
should be handled within the kernel module driver. There's a fair amount
|
||||
of information required to select a suitable timing, which the user-level
|
||||
driver will have to request, and it might have to do additional queries
|
||||
during its evaluation. The abstractions used for this communication will
|
||||
include a growing number of properties to accomodate new card/chipset
|
||||
drivers. It is however desirable that the simple loading of a new module
|
||||
driver is enough to make full use it, without the requirement of having an
|
||||
updated user-level driver.

Here are some tips on writing a new chipset svgalib driver.
|
||||
They don't require knowledge of direct vga programming, even though that
|
||||
helps.
|
||||
The instructions assume:
|
||||
1- A super vga card, that is a card which is extended, but also fully
|
||||
compatible to standard vga. Of the cards available today (in the mass market),
|
||||
all are, with the possible exception of Permedia chipsets.
|
||||
2- A PCI (or AGP) connected card. This is useful for detection of the card,
|
||||
and for finding the linear aperture, as well as knowing it is always there.
|
||||
3- Knowledge of the extended features of the chipset: Usually either as the
|
||||
spec, or a source of a driver for the chipset (XFree86).
|
||||
|
||||
as a start, get the following:
|
||||
1- vgadoc4b.zip[1] (or a later version), includes information on the vga
|
||||
hardware registers, as well as on many chipsets.
|
||||
2- the latest svgalib[2].
|
||||
3- If the card is supported by XFree86, either the link kit (Xlkit.tgz[3])
|
||||
if the card is supported by the XF86_SVGA server, or the XFree86 source
|
||||
([4]), if it is supported by a special server.
|
||||
|
||||
1. in the src subdir of the svgalib distribution, cp skeleton.c to some other
|
||||
name, chipset.c, where chipset is the name of the chipset you intend to
|
||||
support.
|
||||
|
||||
2. now you have to fill the blanks. The functions that need to be are
|
||||
sk_setpage
|
||||
sk_saveregs
|
||||
sk_setregs
|
||||
sk_initializemode
|
||||
sk_unlock
|
||||
sk_test
|
||||
sk_setdisplaystart
|
||||
sk_setlogicalwidth
|
||||
sk_init
|
||||
|
||||
3. When that is done, change all sk_ in the driver to chipset_ (where
|
||||
chipset is the name of the chipset you write the driver for). Then
|
||||
the driver needs to be integrated into svgalib. The files that need
|
||||
to be edited are:
|
||||
Makefile.cfg
|
||||
src/Makefile
|
||||
src/driver.h
|
||||
src/vga.c
|
||||
src/vga.h
|
||||
(It's easy to see what changes are needed in those files, by simply
|
||||
seeing how its done for another driver).
|
||||
|
||||
4. Now is the most interesting time - debugging. Usually (in my experience,
|
||||
in all cases), the driver won't work right immediately. Here are a few
|
||||
debugging tips:
|
||||
|
||||
Setting modes is made of two things: setting the timings, and setting the
|
||||
memory organisation. You can usually tell which is the problem, by noticing
|
||||
if the wrong screen is seen as if some/all pixels are not set to the color
|
||||
they should (memory organisation), or the display looks "stormy" (timings
|
||||
problem). If the problem is timing problem, a digital monitor taht displays
|
||||
horizontal and vertical timings helps. If the horizontal freq is right, but
|
||||
vertical is wrong, then the problem is in the vertical timing. If both horiz
|
||||
and vert are wrong, then either the clock frequency, or the horizontal
|
||||
frequency is wrong.
|
||||
|
||||
If the problem is in memory organisation, It might work in linear mode, so try
|
||||
running testlinear and lineart.
|
||||
|
||||
If the driver fails to restore text mode properly, then usually starting X
|
||||
will work. It won't help restoring text mode, but then you might be able
|
||||
to see the output of the program (using /dev/vcs?, /dev/vcsa?).
|
||||
|
||||
The program mode3 (in lrmi-0.6m subdir) might be able to restore text mode,
|
||||
corrupted by a bad driver.
|
||||
|
||||
The same mode3 might be used for debugging as follows: if a mode, say
|
||||
800x600x256 does not work properly, but mode3 does work, you might try the
|
||||
following run vgatest, select 11 (for 800x600x256), and while the wrong mode
|
||||
is displayed, press d (to recieve a registers dump).
|
||||
then, try mode3 259 ; utils/dumpreg ; mode3, and compare the register dump
|
||||
of vesa mode 259 (800x600x256), with the output from your driver. Try finding
|
||||
out what do the bits that are different mean.
|
||||
|
||||
|
||||
Here are some more details on writing the necessary functions:
|
||||
examples given are from the banshee.c driver, written according to the spec
|
||||
available from 3dfx, and the (hypotethical) milleniumII.c driver, written
|
||||
according to the XFree86 source.
|
||||
|
||||
_setpage:
|
||||
|
||||
This is a simple function. A mistake in this function is indicated by:
|
||||
all linear programs work fine, while in paged memory examples, the problem
|
||||
is that blocks (full width * ??? lines) are moved.
|
||||
|
||||
For millenium, from freebe (this part is unavailable in X source,
|
||||
since X uses only linear mode).
|
||||
{
|
||||
outw(0x3de,(page<<8)|4);
|
||||
};
|
||||
|
||||
For Banshee:
|
||||
{
|
||||
page<<=1;
|
||||
outl(banshee_io_base+0x2c,(inl(banshee_io_base+0x2c)&0xfff00000)|(page)|(page<<10));
|
||||
}
|
||||
|
||||
|
||||
_saveregs, _setregs
|
||||
|
||||
This functions should save and restore the state of the svga card, such that
|
||||
it can be restored to a previous state, no matter what we do. A mistake is
|
||||
indicated by failure to restore text mode properly.
|
||||
|
||||
We should save all registers that we change, or might be changed by other
|
||||
programs (X, SVGATextMode, etc.), here's the banshee_saveregs:
|
||||
|
||||
typedef struct {
|
||||
unsigned int pllCtrl0, pllCtrl1, dacMode, dacAddr,
|
||||
vidProcCfg, vidScreenSize, vgaInit0,
|
||||
vgaInit1, vidDesktopStartAddr,vidDesktopOverlayStride;
|
||||
} *HWRecPtr;
|
||||
|
||||
static int banshee_saveregs(unsigned char regs[])
|
||||
{
|
||||
HWRecPtr save;
|
||||
|
||||
banshee_unlock();
|
||||
|
||||
save=(HWRecPtr)(regs+62);
|
||||
|
||||
regs[BANSHEEREG_SAVE(0)]=__svgalib_inCR(0x1a);
|
||||
regs[BANSHEEREG_SAVE(1)]=__svgalib_inCR(0x1b);
|
||||
save->pllCtrl0=inl(banshee_io_base+0x40);
|
||||
save->pllCtrl1=inl(banshee_io_base+0x44);
|
||||
save->dacMode=inl(banshee_io_base+0x4c);
|
||||
save->dacAddr=inl(banshee_io_base+0x50);
|
||||
save->vidProcCfg=inl(banshee_io_base+0x5c);
|
||||
save->vidScreenSize=inl(banshee_io_base+0x98);
|
||||
save->vgaInit0=inl(banshee_io_base+0x28);
|
||||
save->vgaInit1=inl(banshee_io_base+0x2c);
|
||||
save->vidDesktopStartAddr=inl(banshee_io_base+0xe4);
|
||||
save->vidDesktopOverlayStride=inl(banshee_io_base+0xe8);
|
||||
|
||||
return BANSHEE_TOTAL_REGS - VGA_TOTAL_REGS;
|
||||
}
|
||||
|
||||
If we use the X source, it usually in the functions XXXSave and XXXRestore.
|
||||
It is only needed to translate from XFree86 notation to svgalib notation,
|
||||
and to remember that while the X functions need to save the vga state (usually
|
||||
by calling the vga function to do it, in svgalib the chipset_saveregs/setregs
|
||||
don't need to do that, but only save extended vga info).
|
||||
For MilleniumII, the interesting X functions are: MGA3026Save and
|
||||
MGA3026Restore, here a translation of a part of MGA3026Restore to
|
||||
mill_setregs:
|
||||
|
||||
MGA3026Restore:
|
||||
for (i = 0; i < 6; i++)
|
||||
outw(0x3DE, (restore->ExtVga[i] << 8) | i);
|
||||
|
||||
/* restore DAC regs */
|
||||
for (i = 0; i < sizeof(MGADACregs); i++)
|
||||
outMGA1064(MGADACregs[i], restore->DACreg[i]);
|
||||
|
||||
translates to (assuming sizeof(MGADACregs)==32)
|
||||
for (i = 0; i < 6; i++)
|
||||
outw(0x3DE, (restore[60+i] << 8) | i);
|
||||
|
||||
/* restore DAC regs */
|
||||
for (i = 0; i < 32; i++){
|
||||
OUTREG8(RAMDAC_OFFSET + MGA1064_INDEX, MGADACregs[i]);
|
||||
OUTREG8(RAMDAC_OFFSET + MGA1064_DATA, restore[66+i]);
|
||||
};
|
||||
|
||||
|
||||
_initializemode - This is the trickiest function. If you use the XFree86
|
||||
source, try to translate the appropriate function from X to svgalib (in
|
||||
the milleniumII case, MGA1064Init(mode)). For examples of this translation,
|
||||
see how its done for nv3.c compared to nv/nv3driver.c from X, or apm.c compared
|
||||
to apm/apm_driver.c.
|
||||
If you are working from specs, it usually explained in the spec.
|
||||
|
||||
_unlock:
|
||||
simple function. The skeleton includes the vga unlocking part. If you have
|
||||
specs, they usually explain how to unlock the extended features, if you use
|
||||
the X source, its usually in the EnterLeave function.
|
||||
|
||||
_test - If you are supporting a single chipset of a single manufacturer,
|
||||
on a PCI/AGP, the skeleton driver includes a test for this, just make sure to
|
||||
set VENDOR_ID and CARD_ID properly. Otherwise, either the specs explain
|
||||
how to recognize that you have the right chipset, or its in the function
|
||||
XXXProbe of the XFree86 source.
|
||||
|
||||
|
||||
_setdisplaystart, _setlogicalwidth:
|
||||
vga includes this settings, but with limited range (start<65536,
|
||||
width<2048 bytes). An svga chipset either defines extra bits, for increasing
|
||||
the range, or completely new registers for these values.
|
||||
In the first case, the skeleton driver includes setting the vga part, and
|
||||
the extra bits are either defined in the specs, or in the XXXAdjust function
|
||||
in XFree86 (see mx.c for example of this). In the second case, remove the
|
||||
vga setting part from the functions (see for example rage.c).
|
||||
Note that none of the demo programs test this functions, so if you want to
|
||||
check if they work, the only example I know of is seejpeg (try to see an image
|
||||
larger than the screen)
|
||||
|
||||
|
||||
_init
|
||||
should not need much changes, except for checking memory size (in the spec, or
|
||||
in XXXProbe), and maybe setting MMIO (if other functions use it).

Hi!
|
||||
I wrote a set of SVGAlibish joystick routines while I played with porting
|
||||
DOSDoom to SVGAlib.
|
||||
It is compatible with both the older joystick driver for Linux 1.x and 2.0
|
||||
and the newer joystick driver that is in recent 2.1.x kernels.
|
||||
Some of the code is ripped from the userland tools joystick-0.6.7 and
|
||||
joystick-2.0.6 none of wich has any special license attaced to them.
|
||||
|
||||
The files are:
|
||||
joydev.h: my userland version of the kernel joystick.h
|
||||
vgajoystick.h: library include file analog to vgakeyboard.h and vgamouse.h
|
||||
joystick.c: the library routines.
|
||||
joytest.c: a simple test program/example
|
||||
|
||||
I dunno how useful these will be, but I could at least use them in doom. (Not
|
||||
that joystick control in doom adds anything, I just implemented it for
|
||||
completeness.)
|
||||
|
||||
BUGS:
|
||||
Only one joystick device at any time (but the new 2.1.x driver will let you
|
||||
map 4 axis and 4 buttons to one logical device).
|
||||
|
||||
The routines:
|
||||
|
||||
int joystick_init(const char *joydev, int verbose, FILE *file);
|
||||
This one inits the joystick routines and opens the device. Returna the
|
||||
filedescriptor of the joystick device if successfull or -1 if not.
|
||||
Outputs some messages to stdout id verbose is != 0. If file != NULL it will
|
||||
try to recalibrate the joystick and output the recalibration instructions to
|
||||
the struct file pointed to by file.
|
||||
E.g.
|
||||
|
||||
if (-1 == joystick_init("/dev/js0, 1, stdout))
|
||||
{
|
||||
printf("Joystick init failed\n");
|
||||
exit(1);
|
||||
}
|
||||
|
||||
void joystick_close(void);
|
||||
Shuts down the joystick.
|
||||
|
||||
int joystick_update(void);
|
||||
Reads the joystick and calls the joystick handler if anything events are
|
||||
availible. Should be called every now and then.
|
||||
|
||||
|
||||
void joystick_sethandler(__joystick_handler jh);
|
||||
Install a user supplied joystick handler.
|
||||
|
||||
A user supplied joystick handler would look like this.
|
||||
void joystick_handler(int event, int number, char value);
|
||||
int event - event type:
|
||||
JOY_EVENTAXIS an axis has moved
|
||||
JOY_EVENTBUTTONDOWN a button has been pushed
|
||||
JOY_EVENTBUTTONUP a button has been released
|
||||
int number - the axis or button number for this event 0=x axis or button 1, etc.
|
||||
char value - value for axis events (-128 .. 0 .. 127)
|
||||
|
||||
void joystick_setdefaulthandler(void);
|
||||
Restore the default joystick handler.
|
||||
|
||||
char joystick_getnumaxes(void);
|
||||
char joystick_getnumbuttons(void);
|
||||
Retrun the number of axes/buttons on the joystick.
|
||||
|
||||
char joystick_getaxis(int a);
|
||||
char joystick_getbutton(int b);
|
||||
Querys the jostick state from the default joystick handler if it is used.
|
||||
|
||||
The following macros calls joystick_getaxis() or joystick_getbutton().
|
||||
joystick_getb1() - Gets button 1
|
||||
joystick_getb2() - Gets button 2
|
||||
joystick_getb3() - Gets button 3
|
||||
joystick_getb4() - Gets button 4
|
||||
|
||||
joystick_getx() - Returns the X axis
|
||||
joystick_gety() - Returns the Y axis
|
||||
joystick_getz() - Returns the Z axis
|
||||
|
||||
That all folks,

** Svgalib keyboard scancode remapping: the Readme **
|
||||
|
||||
** Introduction
|
||||
|
||||
After a poll on Slashdot.org about keyboard layouts, I decided to switch from
|
||||
QWERTY to the Dvorak simplified keyboard. (Such is the power of Slashdot!) It
|
||||
was easy to switch the keymaps used by the console and X and even LILO, but
|
||||
svgalib programs that used raw keyboard weren't affected since they interpret
|
||||
the keyboard scancodes into characters themselves - often assuming a standard
|
||||
US keyboard with QWERTY layout.
|
||||
|
||||
In order for my machine to present a ``unified front'' with a single consistent
|
||||
keyboard layout, I added to svgalib the ability to remap scancodes. This is
|
||||
done in keyboard_getevents(), before the event handler is called, so it will
|
||||
work whether or not a program provides its own handler. Programs that do not
|
||||
use raw keyboard are not affected, so by setting both the console and svgalib
|
||||
itself to use the same keymap a consistent keyboard layout is available to all
|
||||
svgalib programs.
|
||||
|
||||
|
||||
** Background
|
||||
|
||||
When you press or release a key on your keyboard, it sends a byte of data to
|
||||
your computer. The top bit indicates whether the key was pressed or released,
|
||||
and the lower seven bits hold the scancode, a number that uniquely identifies
|
||||
the key. A program on the computer interprets these scancodes as representing
|
||||
characters (`A', `%', etc) or actions to be taken (`Page Up', `Back Space') or
|
||||
modifiers that alter the interpretation of other keys (`Shift', `Alt', etc).
|
||||
Most programs do not perform this interpretation themselves, but leave it up
|
||||
to some other piece of software: the system BIOS, or the operating system,
|
||||
or the graphical user interface system.
|
||||
|
||||
On Linux this is normally done by the kernel or by the X server for X clients,
|
||||
but this doesn't meet the needs of some programs (especially games) which
|
||||
care more about whether a key is up or down than what it means and treat the
|
||||
modifiers the same way as other keys. These programs open the keyboard in `raw'
|
||||
mode and deal directly with scancodes.
|
||||
|
||||
The problem comes because these programs often do need to interpret the keys
|
||||
into characters, or it is important for a certain key to be identifiable to
|
||||
the user as being associated with a certain key. For instance, a game player
|
||||
might need to type a description of a saved game or be directed to press a
|
||||
certain key to activate a game feature. Interpretation of keyboard scancodes
|
||||
can be difficult since there are many different keyboard layouts which do not
|
||||
have the same associations between scancodes, modifiers, characters, and
|
||||
commands. So the author of the program must choose between writing a complex
|
||||
and customizable conversion routine that can handle any layout the user might
|
||||
have, and a simple routine that is hard-coded to use a single layout. In the
|
||||
latter case, users of other keyboard layouts will encounter numerous
|
||||
discrepancies between what he or she tries to type and what the program
|
||||
interprets.
|
||||
|
||||
|
||||
** How it works
|
||||
|
||||
Svgalib's scancode conversion is meant to at least partially fill this gap by
|
||||
converting the scancodes that the keyboard produces to equivalent, or nearly
|
||||
equivalent, scancodes for the keyboard layout that the program expects. The
|
||||
program then (hopefully) interprets the new scancode into the intended
|
||||
character.
|
||||
|
||||
As an example, let us consider a US keyboard with Dvorak layout and the game
|
||||
Quake, which expects a US keyboard with QWERTY layout. Both layouts have the
|
||||
same scancodes for each physical key, but different characters are produced.
|
||||
For intance, the first row of letters produces the scancodes 16 through 27, but
|
||||
on QWERTY this produces the charaters qwertyuiop[] while Dvorak produces
|
||||
',.pyfgcrl/=. Thus when the Dvorak letter `p' is pressed, the scancode 19
|
||||
is interpreted by Quake as the letter `r', which occupies scancode 19 on the
|
||||
QWERTY layout.
|
||||
|
||||
The solution lies in the fact that svgalib acts as an intermediary between the
|
||||
keyboard and the program and has the opportunity to present a different
|
||||
scancode to the program than the keyboard produced. In this case we tell Quake
|
||||
that the scancode was not 19 but rather 25, which is the letter `p' in the
|
||||
QWERTY layout, so when Quake interprets the scancode the correct character is
|
||||
produced.
|
||||
|
||||
|
||||
** The keymap files
|
||||
|
||||
In order to know what scancodes to convert to what other scancodes, a keymap
|
||||
file is read which lists scancodes produced by the keyboard and their
|
||||
equivalents in the layout expected by the program.
|
||||
|
||||
A program called svgakeymap is provided to generate these maps from the
|
||||
keytable files in /usr/lib/kbd/keytables; you must have perl for it to work.
|
||||
Creating a keymap file with svgakeymap is easy; to make a map to convert
|
||||
scancodes from a US Dvorak keyboard to a US QWERTY keyboard as for our example
|
||||
above:
|
||||
|
||||
svgakeymap dvorak us > dvorak-us.keymap
|
||||
|
||||
The path and .map and .gz suffixes are automatically added if necessary. If
|
||||
your keytables are stored elsewhere, specify a complete path. If only one
|
||||
keytable is specified, a keymap is generated that performs no conversions but
|
||||
contains the correct key names so you can specify scancodes used by fake
|
||||
keyboard and mouse events by name instead of by number. If none are specified,
|
||||
this is done for the standard US QWERTY layout.
|
||||
|
||||
dvorak-us.keymap and default.keymap (the US QWERTY layout) are provided with
|
||||
the svgalib distribution and can serve as an example if you wish to make your
|
||||
own keymap files manually or create an improved generator.
|
||||
|
||||
|
||||
** Configuration
|
||||
|
||||
You can specify a keymap to use for all svgalib programs (keeping in mind that
|
||||
only those that use raw keyboard are affected) by putting a line like this into
|
||||
libvga.config or ~/.svgalibrc:
|
||||
|
||||
kbd_keymap /etc/vga/dvorak-us.keymap
|
||||
|
||||
You must specify a complete path to the keymap file. If no keymap is specified,
|
||||
no conversion is performed.
|
||||
|
||||
You can also override the global keymap by setting the environment variable
|
||||
SVGALIB_KEYMAP to point to the appropriate keymap file. This can be useful if
|
||||
some programs support alternate keymaps directly but not others, or if
|
||||
different users use their own keyboard layouts based on preference.
|
||||
|
||||
|
||||
** Security issues
|
||||
|
||||
It can be dangerous to let users arbitrarily reassign keyboard scancodes; for
|
||||
instance all keys could be routed to an unused scancode, making the console
|
||||
unusable. To prevent this, put the option kbd_only_root_keymaps into
|
||||
libvga.config; only keymaps owned by root will be accepted, so the available
|
||||
keymaps can be limited to safe ones.
|
||||
|
||||
|
||||
** Bugs and limitations
|
||||
|
||||
There are no known bugs, but there probably are some. If you find any please
|
||||
let me know at brion@pobox.com.
|
||||
|
||||
Limitations however we definitely have. The scancode conversion performed is
|
||||
very simple, and can only achieve 100% success when the keyboard layouts being
|
||||
converted between differ _only_ in arrangement of keys while producing the same
|
||||
characters from each key. Example: the de facto standard Dvorak keyboard has
|
||||
the left and right brackets (`[' and `]') on separate keys, with the curly
|
||||
braces (`{' and `}') produced by those keys when shifted. The standard QWERTY
|
||||
keyboard produces those characters the same way, the only difference is that
|
||||
the keys are a row higher on Dvorak; switching the scancodes around results in
|
||||
proper character interpretation. However the official ANSI standard Dvorak
|
||||
layout has tho two brackets on _the same key_, one regular and one shifted.
|
||||
The curly braces similarly have their own key. These cannot be properly mapped
|
||||
by scancode to the QWERTY keyboard since they produce different characters
|
||||
in conjunction with modifiers, and the wrong character is produced by the
|
||||
program.
|
||||
|
||||
This could be worked around by interpreting the modifiers in svgalib and
|
||||
simulating the proper modifier/character keypress/release sequences, but it
|
||||
would be very complex and would do nothing to help the situation where
|
||||
characters on the physical keyboard layout do not exist on the target layout
|
||||
(quite likely when dealing with national or language-specific keyboards);
|
||||
they cannot be converted into any key sequence since they do not exist.
|
||||
|
||||
Ultimately it might be better to set up a ``medium-rare'' keyboard mode where
|
||||
keys are interpreted into characters but ``raw''-style non-interpreted key
|
||||
press and release events are available.
|
||||
|
||||
|
||||

multi-monitor support is still very experimental, and not
|
||||
very easy to setup. Here's a copy of a message I sent to
|
||||
the mailing list:
|
||||
|
||||
|
||||
First: only nvidia, 3dfx, sis and i740 cards can be secondary cards,
|
||||
(though the primary can be anything, including vesa).
|
||||
Second: as far as I can understand, once both cards are enabled, there
|
||||
ought to be a resource contention (in hardware) between the cards for
|
||||
the vga regions (IO 0x3c0-0x3df and MEM 0xa0000-0xbffff). I don't know
|
||||
how it is supposed to be solved, but in practice, if I ignore it in my
|
||||
system, it just works.
|
||||
|
||||
If anybody else has successfully run svgalib on a secondary card, please
|
||||
tell me, and if you had to do something different from what I did, a
|
||||
detailed report to the list might help others.
|
||||
|
||||
Here's my setup:
|
||||
|
||||
I have two vga cards: AGP (1:0.0) nVidia TNT2 and (PCI0:0f.0) Riva128.
|
||||
The AGP card is the primary (in the BIOS option "initialize AGP card
|
||||
first" is selected). My boot sequence includes the following code to
|
||||
initialize the secondary card:
|
||||
|
||||
/usr/local/sbin/vbios.x86emu
|
||||
/usr/local/sbin/vga_reset
|
||||
/sbin/setpci -s 00:0f.0 COMMAND=2
|
||||
|
||||
the vbios.x86emu is the same as distributed in x86emu-0.6 (from ftp.scitechsoft.com)
|
||||
except that in debug.h the line
|
||||
#define CONFIG_ACTIVE_DEVICE 1
|
||||
is replaced by
|
||||
#define CONFIG_ACTIVE_DEVICE 0
|
||||
(so that the active device is not initialized by x86emu).
|
||||
|
||||
the setpci line enables memory access (of the drivers supporting
|
||||
secondary card, nv3 and i740 use only memory mapped IO, sis and banshee
|
||||
need I/O access as well, so you need COMMAND=3). The COMMAND register
|
||||
might have other bits set, so you might try to see its value first, and
|
||||
then set the 0,1 bits.
|
||||
|
||||
I have two config files in /etc/vga:
|
||||
libvga.config.0 - for the scondary card:
|
||||
|
||||
novccontrol
|
||||
secondary
|
||||
include /etc/vga/libvga.config.common
|
||||
HorizSync 30 54
|
||||
VertRefresh 40 120
|
||||
|
||||
The novccontrol and secondary options are necessary for a secondary
|
||||
card. The include statement is for a card with common configurations -
|
||||
mouse, keyboard, etc.
|
||||
|
||||
libvga.config.1 - for the primary:
|
||||
|
||||
PCIStart 1 0
|
||||
include /etc/vga/libvga.config.common
|
||||
HorizSync 30 115
|
||||
VertRefresh 40 160
|
||||
|
||||
The pcistart option is necessary to make sure that svgalib skips the
|
||||
first card (in PCI order), and so finds the AGP card.
|
||||
|
||||
to run a program on the primary card, in the usual way, I do
|
||||
|
||||
export SVGALIB_CARD=1
|
||||
/svgalib/demos/vgatest
|
||||
|
||||
to run a program on the secondary card:
|
||||
|
||||
export SVGALIB_CARD=0
|
||||
/svgalib/demos/vgatest
|
||||
|
||||
There are a few differences for a program running on secondary card:
|
||||
|
||||
- The program is not aware of VC switches, so you can switch to another
|
||||
console, and the program will still run (and display).
|
||||
- The program can't event system (mouse or raw keyboard).
|
||||
- Standard VGA modes and paged memory modes might have problems.
|
||||
|
||||
What this limitations mean is that usual svgalib program might not be
|
||||
useful for a secondary card. I use the secondary display for
|
||||
watching TV, movies and slideshows. Eye candy programs (such as
|
||||
synaesthesia) might also work, after a few changes, but interactive
|
||||
programs (zgv, games) are unusable right now. I intend to add support
|
||||
for Vojtech Pavlik's input event system to svgalib-2.0, so that
|
||||
interactive program will be usable as well.

|
||||
|
||||
0. Introduction
|
||||
|
||||
Here is some info on writing patches and/or adding support for
|
||||
further chipsets. The info on the chipset drivers is outdated, but
|
||||
better than nothing and get you started.
|
||||
|
||||
As a side note, other than a.out, ELF does not allow to have some
|
||||
symbols global to svgalib which are not accessible to user
|
||||
programs.
|
||||
|
||||
Because of that, if possible all the symbols and functions in your
|
||||
program should be static. Those which can not be static should
|
||||
have a name like: "__svgalib_*" to mark them as internals s.t.
|
||||
people using them get what they deserve. Please do only add a new
|
||||
function to the user interface if it is really unavoidable. Better
|
||||
add some new parameters to an existing function.
|
||||
|
||||
Adding a new function would definitly result in loosing a.out
|
||||
compatibility thus removing the chance to use new cards and such
|
||||
with old a.out binaries where the source is not available (doom
|
||||
comes to mind).
|
||||
|
||||
A new function should be really important to outweigh this draw
|
||||
back.
|
||||
|
||||
1. Indenting
|
||||
|
||||
Due to some request (and I heard it b4) all the sources were now
|
||||
automatically indentified.
|
||||
|
||||
There were some requests for indent -gnu but it looks painful. I
|
||||
opted for -kr (there were requests for it as well) as it is not
|
||||
only nicer but also what is done in the linux-kernel and this is
|
||||
certainly a program only usable for linux.
|
||||
|
||||
I dunno if emacs is confused by -kr, but to be honest this is a
|
||||
big all-in-one egg-giving-wool-milk-sow (as we say in german), and
|
||||
you won't tell me that this several megs beast is unable to edit
|
||||
this and I can't use -kr due to some restrictions of emacs. That
|
||||
would be really ridiculous. If it is the case just make emacs
|
||||
better.
|
||||
|
||||
The OneModeEntry macro is eaten by indent (I would say it is an
|
||||
indent bug, I might send a bug report to them), please ensure (if
|
||||
at all possible) that your code can be passed through indent (use
|
||||
the INDENT-OFF comments as shown in some sources for
|
||||
OneModeEntry).
|
||||
|
||||
You can use `make indent-gnu' (if you have a recent enough (I use
|
||||
1.9.1) indent) to switch to your favorite style. But please ensure
|
||||
your patches fit into this now declared as "official style"
|
||||
sources. (Use `make indent' to reformat).
|
||||
|
||||
Do not use it too often though as most indent's tend to add empty
|
||||
lines at certain places in the source.
|
||||
|
||||
2. Structure of the chipset drivers
|
||||
|
||||
The chipset specific registers saving function (saveregs) is only
|
||||
used directly to save the textmode registers at initialization.
|
||||
|
||||
The chipset specific registers restoring function (setregs) is only
|
||||
used directly to return to textmode, and when setting a VGA mode
|
||||
after an SVGA mode.
|
||||
|
||||
The registers for each mode are stored like the ET4000 modes in
|
||||
VGAlib 1.2, i.e. the extended registers at the end. The following
|
||||
functions must be provided in a driver:
|
||||
|
||||
saveregs( unsigned char regs[] )
|
||||
Saves the chipset-specific registers in regs, starting at
|
||||
array index EXT (after the VGA registers).
|
||||
|
||||
setregs( unsigned char regs[] )
|
||||
Sets the chipset-specific registers stored in regs from
|
||||
index EXT.
|
||||
|
||||
modeavailable( int mode )
|
||||
Returns nonzero if mode is available (should check video
|
||||
memory).
|
||||
|
||||
getmodeinfo( vga_modeinfo *modeinfo )
|
||||
Fills in chipset specific field of mode information
|
||||
structure: maxlogicalwidth, startaddressrange (mask of
|
||||
significant bits), and maxpixels (video memory divided by
|
||||
the number of bytes per pixel). haveblit indicates whether
|
||||
bitblt functions are available.
|
||||
Note: providing extended info and an aperture with size
|
||||
>= memory and setting bits 4 and 6 in flags will
|
||||
automatically enable linear addressing support.
|
||||
|
||||
|
||||
setmode( int mode, int previous_mode )
|
||||
Sets all registers for a mode; returns nonzero if mode not
|
||||
available. __vga_setregs can be called to set the VGA
|
||||
registers.
|
||||
|
||||
unlock()
|
||||
Unlocks chipset-specific registers.
|
||||
|
||||
lock()
|
||||
Lock (protect) chipset-specific registers. Currently not
|
||||
called.
|
||||
|
||||
test()
|
||||
Identify chipset; initialize (check memory and type) and
|
||||
return nonzero if detected.
|
||||
|
||||
setpage( int page )
|
||||
Set 64K page number to be mapped at 0xa0000.
|
||||
|
||||
init( int force, int par1, ... )
|
||||
Initialize memory and type; called by test. If force is 1,
|
||||
the chiptype or the amount of memory can be forced (this
|
||||
is pretty useless).
|
||||
|
||||
The following functions provide for things like page flipping
|
||||
and hardware scrolling virtual desktops.
|
||||
|
||||
setdisplaystart( int address )
|
||||
Sets the display start address in video memory in pixels.
|
||||
|
||||
setlogicalwidth( int width )
|
||||
Sets the logical scanline length in bytes. Usually a
|
||||
multiple of 8.
|
||||
|
||||
The function getchipset() in vga.c must call the test routine for
|
||||
the chipset. The chipsetfunctionslist must be have a pointer
|
||||
to the chipsetfunctions table for the chipset (which is the only
|
||||
global symbol in a chipset driver). Also, vga.h contains a magic
|
||||
number for each chipset. Also driver_names[] in vga.c has to
|
||||
contain a name for each driver at the correct position.

Notes for the VESA driver:
|
||||
|
||||
The driver's autodetection is disabled by default, so in order to use it,
|
||||
the line
|
||||
chipset VESA
|
||||
must be added to the config file (usually /etc/vga/libvga.config).
|
||||
|
||||
The error:
|
||||
Int 0x10 is not in rom (xxxx:xxxx)
|
||||
is usually caused by running linux using loadlin, after loading a dos tsr
|
||||
that changes the int 10 vector, or after windows 95, that does the same
|
||||
thing. The solution, is either to use lilo, or run loadlin after a clean
|
||||
dos boot.
|
||||
|
||||
|
||||
There is a new config file option that affects the vesa driver:
|
||||
VesaText
|
||||
If this option is used, the driver sets 80x25 text mode (using vesa bios)
|
||||
before setting any standard vga mode.
|
||||
|
||||
This option was added in order to enable standard vga modes with the vesa
|
||||
driver on Matrox Millenium, but now it has the following effect:
|
||||
(read in a fixed width font)
|
||||

Riva 128 does not restore works

|
||||
|
||||
Matrox
|
||||
Millenium works does not set standard vga
|
||||
modes properly.
|
||||
|
||||
A list of cards known to work with the VESA driver is:
|
||||
* Riva128 (both on a STBV128 and a Viper330)
|
||||
* RivaTNT
|
||||
* Matrox Millenium 2
|
||||
* Matrox Mystique
|
||||
* Matrox Productiva G100
|
||||
* Matrox Millenium G200
|
||||
* Neomagic Magicgraph 128XD (in a Dell Inspiron laptop)
|
||||
* S3 375 Virge/DX ( A "Trident Video Excel 3D Accelerator" )
|
||||
* S3 Trio3D
|
||||
* Cirrus Logic GD5446
|
||||
* Rendition V1000 - Only modes up to 800x600 seem to work
|
||||
* ATI Expression+ PC2TV 2MB (RageII chipset) - tested only modes up
|
||||
to 800x600 resolution
|
||||
* i740 (Diamond Stealth G460)
|
||||
* Voodoo Banshee
|
||||
* Alliance Technology AT24
|
||||
|
||||
Please note that some of this cards have also failed to work in some
|
||||
cases, so it is _very_ configuration dependent.
|
||||
|
||||
For Matrox cards, the advice is to upgrade to the latest bios from Matrox.

Be sure to read the svgalib.FAQ man 7 svgalib.faq

Have to decide what exactly is G320x200x256 (VGA Mode 13h or SVGA
|
||||
packed-pixel). A separate Mode X would be nice too.
|
||||
|
||||
A set of functions to handle page-flipping would be nice. (e.g. a
|
||||
vga_setvideopage() that returns the new video start address)
|
||||
|
||||
Support for more chipsets?
|
||||
|
||||
Clean up keyword parsing code.
|
||||
|
||||
Kernel support for page-flipping.
|
||||
|
||||
automatic console restore on device close.
|
||||
|
||||
really reliable vc switching.
|
||||
|
||||
There are races in the mouse code when the mouse device is closed in the
|
||||
signal handler on a vc switch. Again, probably kernel support is due.
|
||||
|
||||
start marking functions that will become obsolete.
|
||||
|
||||
Move away from hard-coded mode numbers:
|
||||
|
||||
Think what would happen if a program is compiled to call
|
||||
vga_setmode(G1280x1024x256) and we change the mode number to
|
||||
something else... This has happened before. The solution is either
|
||||
to provide a getmodenum(xres, yres, colordepth, layout) function, or
|
||||
a setmode(xres, yres, colordepth, layout) function or vow not to
|
||||
change the definitions of the mode numbers (i.e. new modes can only
|
||||
be added to the end of the list).
|
||||
|
||||
More RamDAC support. The S3 code should have no problem with 868, Trio and
|
||||
9xx chips except that boards that uses those chips usually uses
|
||||
newer/unsupported RamDACs as well.
|
||||
|
||||
Multiple-adaptor support.
|
||||
|
||||
IBM RGB52x >8bpp support.

create a different libvga.config for each card, which contains the

|

|
||||
|
||||
Some explanations:
|
||||
|
||||
When the environment variable SVGALIB_CARD is set, svgalib opens the
|
||||
config file /etc/vga/libvga.config.$SVGALIB_CARD, instead of the usual
|
||||
/etc/vga/libvga.config. So, if I want to run zgv on the nv3 card, I do
|
||||
export SVGALIB_CARD=nv3 ; zgv
|
||||
|
||||
The helper keyword can be used similar to the device keyword, to tell
|
||||
svgalib which device to open.
|
||||
|
||||
All cards except for the primary need to use the secondary and
|
||||
novccontrol keywords. Secondary tells svgalib not to try to use the
|
||||
standard VGA ports when accessing this card (since only one card can be
|
||||
accessed with those, and that is the primary). NoVCControl tells svgalib
|
||||
not to check or try to control the VC, so you can run an svgalib program
|
||||
on a secondary card, while working normally on the main head, including
|
||||
switching virtual consoles.
|
||||
|
||||
You should use "mouse none", or "mdev" options to make sure no two
|
||||
programs open the mouse at the same time. (Though it is possible with
|
||||
most mice, and can give some funny results).
|
||||
|
||||
XFree86 likes to disable all PCI video cards that it does not use,
|
||||
whenever it is started, or switched to, so if you switch in and out of X
|
||||
on your main card, you need to patch your X server to prevent this
|
||||
behavior. If you only run X on the main card, and don't return to
|
||||
text mode, there is no need to patch X.
|
||||
|
||||
|
||||
There are no limitations on the primary card. As you can see, I currently
|
||||
use nvidia, mystique and rage (mach64) cards as secondaries. Also known to
|
||||
work are sis, r128 (including radeon), laguna, trident and s3 (trio and up)
|
||||
cards.
|
||||
|
||||
|
||||
The main issue with secondary cards is initializing them. If your BIOS
|
||||
initializes them, that's the best (I heard rumors of such BIOSes, but
|
||||
never something concrete). The next option is x86emu, this almost always
|
||||
works (on x86 systems). It also works on some other arches, if you use PC
|
||||
video cards. If even that fails, then C code is available to initialize some
|
||||
mach64 cards, and old matrox cards (before G100).

.SH DESCRIPTION
|

The chipset drivers of svgalib inquire the mode of the graphic card when the application

is started and restore it when the svgalib application quits.
|

.B dumpreg
|

prints this information to stdout.
|

|
||||
This is useful for debugging or adding modes to a device driver. For example you can
|
||||
use Xfree86 to setup a given mode timing, then run
|
||||
.B dumpreg
|
||||
and use it's stdout to make your chipset driver use exactly this timing.
|
||||
|
||||
However, the recent change of svgalib to hunt an own free virtual console does not allow
|
||||
this, because it will make Xfree86 return to textmode first. You can avoid this by using
|
||||
the second form where
|
||||
.I N
|
||||
is the number of the virtual console on which Xfree86 runs (usually 7) as root.

fix132x43 \- fix problems with certain (132 column) graphics modes
|

dump the state of the card as the svgalib chipset driver sees it.
|
||||
.SH SYNOPSIS
|
||||
|
||||
.BI fix132x43 " options"
|
||||
|
||||
.SH DESCRIPTION
|
||||
This program tries to fix problems with extended textmodes on some cards. The problem is that for
|
||||
132x43 textmode, some BIOS's set the vertical display end register to 349 (350), instead of 343
|
||||
(344 = 3 * 8 scanlines). Because in Linux textmode video memory is usually filled with old text
|
||||
that has already scrolled away (this includes the area below the 43rd textmode line, which changes
|
||||
when the console scrolls), the top half of a constantly changing irrelevant text line is visible
|
||||
at the bottom of the screen, which is very annoying.
|
||||
|
||||
This program sets the VGA Vertical Display End register to the proper value.
|
||||
|
||||
This problem is at least present in the BIOS of most Cirrus Logic 542x based cards, and
|
||||
some WD90C03x based cards.
|
||||
|
||||
The
|
||||
.B LINES
|
||||
environment variable is used to detect 43 or 44 line consoles.
|
||||
|
||||
.SH OPTIONS
|
||||
You have to specify exactly one of the following options:
|
||||
.TP
|
||||
.B -f
|
||||
Fix problem of annoying changing line of text at bottom of screen.
|
||||
.TP
|
||||
.B -v
|
||||
Switch to 9 line characters (400 line frame, 70 Hz).
|
||||
.TP
|
||||
.B -w
|
||||
Switch to 11 line characters (480 line frame, 60 Hz).
|
||||
|
||||
.B fix132x43
|

does not usually provide this option but it can be enabled in the source of
|

.BR fix132x43.
|

.SH NAME

restorefont \- save or restore the SVGA font for textmode.
|

.SH SYNOPSIS
|
||||
|
||||
.BI "restorefont {-r|-w} " filename
|
||||
|
||||
.SH DESCRIPTION
|
||||
The font used by SVGA when in textmode is written to or restored from
|

.IR filename
|
||||
using the
|

.BR vga_gettextfont "(3) and "
|
||||
.BR vga_puttextfont (3)
|
||||
functions.
|
||||
|
||||
.SH FILE FORMAT
|
||||
The VGA font file
|
||||
.I filename
|
||||
has the following format:
|
||||
|
||||
.RS
|
||||
.BR Offset:
|
||||
.br
|
||||
.BR " 0 - 31 " "Character 0"
|
||||
.br
|
||||
.BR " ... " " ..."
|
||||
.br
|
||||
.BR "8164 - 8195 " "Character 255"
|
||||
.RE
|
||||
|
||||
Each row of a character bitmap is stored as a byte (8 pixels).
|
||||
The space that is left from the 32-byte buffer for each character
|
||||
is ignored, e.g. a 16 line font uses only offsets 0 - 15 of each character.
|
||||
|
||||
Linux textmode screen resolutions:
|
||||
|
||||
.BR 80x25 " 16 line font 400 scanlines"
|
||||
.br
|
||||
.BR 80x28 " 14 line font 400 scanlines"
|
||||
.br
|
||||
.BR 80x50 " 8 line font 400 scanlines"
|
||||
|
||||
The font sizes and resolutions of extended textmodes depend on the
|
||||
video card type and BIOS:
|
||||
|
||||
.BR 132x25 " 14 line font 350 scanlines (ugly)"
|
||||
.br
|
||||
.BR 132x25 " 16 line font 400 scanlines"
|
||||
.br
|
||||
.BR 132x43 " 8 line font 350 scanlines (use fix132x43 to fix/improve)"
|
||||
.br
|
||||
.BR 132x50 " 8 line font 400 scanlines"
|
||||
.br
|
||||
|
||||
Using a font that has less lines per character than the textmode works, but
|
||||
the characters are smaller. Using a font that is bigger than the textmode
|
||||
font results in the bottom part of characters being cut off.
|
||||
|
||||
The svgalib distribution contains sample fonts with 8, 14 and 16 line characters
|
||||
in the files
|
||||
.IR utils/font8 ", " utils/font14 ", and " utils/font16 .
|
||||
|
||||
The
|
||||
.BR convfont
|
||||
(1) program can be used to convert fonts straightforwardly stored
|
||||
character-after-character (i.e. each character only uses 8/14/whatever
|
||||
bytes), to the 32-byte per character format that
|
||||
.B restorefont
|
||||
requires.
|
||||
|
||||
The purpose of this program is usually to recover from a crashed console due to an
|
||||
svgalib, Xfree or other program bug. First save the state of the SVGA card when on a
|
||||
text console. After the crash restore this state. The
|
||||
.BR savetextmode (1)
|
||||
and
|
||||
.BR textmode (1)
|
||||
script makes this procedure very easy.
|
||||
|
||||
The national/fontpak packages, which include kernel patches, allow different
|
||||
textmode fonts to be used in different virtual consoles. These have been
|
||||
superseded by the kbd package (in the kernel since ages). See the
|
||||
.BR setfont (8)
|
||||
utility of the kbd package as a starting point.
|
||||
|
||||
Recent kernels support up to 2 fonts with 512 chars each. Recent versions
|
||||
of svgalib take this into account and extend the size of the datafile accordingly.

|

.B restorepalette

without arguments sets the standard VGA palette. This can be useful

if it is somehow messed up.

With a

<chuckb@alice.wonderland.caltech.edu>).

This allow a user to set up a file that looks like this one
|

(These color map definitions are the same as the default VGA ones.
|

Alter to suite personal tastes). The first column contains the number of

the color to set, then follow three integers in range 0 - 63 (lowest to

|

The inline comments are the

only kind of allowed, as I use a little
|
||||
.BR fscanf (3)
|

trick to get them. Blank lines
|

are ok, but not pure comment lines. See the comments in my code, also.
|

|

This allows people to set up custom palettes for use in virtual console text
|
||||
modes. I use it all the time. When combined with a color-syntax editor like
|
||||
jed-0.97+ or color-ls, etc., being able to choose your own text-mode palette is
|
||||
quite a bonus. I set mine up via
|
||||
.B restorepalette /etc/palette
|
||||
in my
|
||||
.IR /etc/rc .
|
||||
If the program is given the correct permissions, then individual users can
|
||||
have
|
||||
.B restorepalette ~/.palette
|
||||
or some such thing in their shell startup
|
||||
files.
|
||||
Of course, it shouldn't be done when starting remote shells or when
|
||||
under X, so some kind of test that
|
||||
.B TERM
|
||||
is a virtual console is needed for that case.

Please do not fiddle with the contents of the file except when you know what you do. It

this command available to all users on your system.
|
||||
|
||||
The purpose of this program is usually to recover from a crashed console due to an
|
||||
svgalib, Xfree or other program bug. First save the state of the SVGA card when on a
|
||||
text console. After the crash restore this state. The
|
||||
.BR savetextmode (1)
|
||||
and
|
||||
.BR textmode (1)
|
||||
script makes this procedure very easy.

.SH DESCRIPTION
|

in your path and use the shell script
|

.B runx
|

to run X.

.RE
|

|

Note that this doesn't help with syncing problems.
|

A more rigorous alternative is to run the
|
||||
.BR savetextmode (1)
|
||||
script before running X, and
|
||||
.BR textmode (1)
|
||||
after. This will restore the textmode registers and the VGA palette in addition to the VGA font.

|

are in your

the

|

These are simple scripts to save the SVGA register state when in textmode to the
|
||||
files
|
||||
.IR /tmp/fontdata " and " /tmp/textregs
|
||||
or to restore it from these files.
|

|
||||
The actual utilities used are
|
||||
.BR restorefont (1),
|
||||
.BR restoretextmode "(1), and "
|
||||
.BR restorepalette (1).
|
||||
|
||||
The purpose of these scripts program is usually to recover from a crashed console due to an
|
||||
svgalib, Xfree or other program bug.
|
||||
|
||||
You do this by being a smart guy and running
|
||||
.B savetextmode
|
||||
right after booting of your machine,
|
||||
.B prior
|
||||
to any problems. Then, in case the SVGA state is hosed and you sit in front of a blank or
|
||||
useless console, change VC (maybe login) to get to a shell. Or exist the currently running
|
||||
program with
|
||||
.BR <Ctrl>-C ", "
|
||||
.BR <Ctrl>-<Alt>-<Backspace> ,
|
||||
or whatever applies. Once you got a shell, run
|
||||
.B textmode
|
||||
and it will hopefully render your console useable again.
|
||||
|
||||
To make it clear: You do all this while not seeing anything on your console screen, you
|
||||
enter this information blindly or after logging in from a network. Also, if the keyboard is
|
||||
left in raw mode, nothing can really help you as you cannot enter anything which a shell
|
||||
will understand.

.SH NAME
|

setmclk \- adjust the memory timing of certain Cirrus cards.
|
||||
.SH SYNOPSIS
|
||||
|
||||
.BI setmclk
|
||||
|
||||
.SH DESCRIPTION
|
||||
This program sets the
|
||||
.B memory clock
|
||||
of Cirrus 5424/26/28 cards.
|
||||
|
||||
The first three values could be set by utility programs that
|
||||
came with my card (AVGA3), but somewhat higher values seem to work (on my
|
||||
card at least). It may be that better and more recent Cirrus cards use a
|
||||
higher value as boot-up default. It should depend on DRAM speed, but it
|
||||
seems to be more dependant on the card logic.
|
||||
|
||||
I have the impression that many Cirrus 542x cards suffer from horrible
|
||||
BIOS version/DRAM timing misconfigurations. Perhaps even some versions of
|
||||
MS-Windows drivers change the MCLK register. In any case, the boot-up BIOS
|
||||
default (0x1c) may be inappropriately low for the type of DRAM timing most
|
||||
cards use.
|
||||
|
||||
Using a higher memory clock gives a very significant performance improvement;
|
||||
with high dot clock modes (like 640x480x16M or 1150x900x256) performance can
|
||||
be more than twice that of the standard 50 MHz clock. This goes for both
|
||||
(VLB) framebuffer access and accelerated features (bitblt). This also helps
|
||||
XFree86 server performance, but only if the XFree86 Cirrus driver doesn't
|
||||
set the memory clock register (it should work for XFree86 1.3 and 2.0).
|
||||
Use at your own risk!
|
||||
|
||||
Note that the
|
||||
.B dot clock
|
||||
is something entirely different. There does not
|
||||
seem to be much correlation between the two (i.e. if a high dot clock gives
|
||||
screen problems, using a high memory clock is not likely to fix it, other
|
||||
than improving speed).
|
||||
|
||||
The actual
|
||||
.B memory clock
|
||||
is hard compiled into the program. It defaults to 0x1c. You can change this value
|
||||
and some suggestiong come in th source of the utility.
|
||||
|
||||
This utility is part of svgalib and can be found in the

||||

||||
subdirectory of the original svgalib distribution. However, it is not installed
|
||||
by default, s.t. it is unclear where you can find it if your svgalib was install
|
||||
linux distribution.
|
||||
|
||||
In case of any such problem, simply get an svgalib distribution from the net. You
|
||||
don't need to install it. Just
|
||||
.B make
|
||||
in the

If only one keytable is specified, a keymap is generated that performs no

conversion but contains the proper key names for that layout. If no keytables

are specified, the standard US QWERTY keyboard is used.

|

The generated keymap is sent to the standard output and may be redirected

|
||||
.SH NAME
|
||||
gl_bcircle \- draw a filled or unfilled Bresenham circle
|
||||
|
||||
.SH SYNOPSIS
|
||||
.B #include <vgagl.h>
|
||||
|
||||
.BI "void gl_bcircle(int " x ", int " y ", int " r ", int " c ", int " fill ");"
|
||||
|
||||
.SH DESCRIPTION
|
||||
Draw a Bresenham circle of radius
|
||||
.I r
|
||||
in color
|
||||
.I c ,
|
||||
centered at
|
||||
.I ( x ", " y ).
|
||||
|
||||
.I Fill
|
||||
should be 0 for a hollow circle, or any other value for a solid color.
|
||||
|
||||
This function differs from gl_circle (3) and gl_fillcircle (3) in that it
|
||||
looks good in 320 x 200 screen modes. The modified algorithm was provided
|
||||
by Chris Atenasio <chris@svgalib.org>, and is based upon Bresenham's
|
||||
formula.
|
||||
|
||||
Note that the "circle" is technically an ellipse, and is actually wider
|
||||
than it is tall. Therefore,
|
||||
.I r
|
||||
is equal to the circle's height, but is less than its width. This
|
||||
distortion is necessary to accomodate the 8:5 aspect ratio (e.g., 320 x
|
||||
200).
|
||||
|
||||
I don't recommend using this function in standard 4:3 screen modes (e.g.,
|
||||
640 x 480 and higher). Furthermore, care must be taken so that a circle
|
||||
drawn with this function isn't copied to a screen with a different aspect
|
||||
ratio. Otherwise, the result may be undesirable.

.SH DESCRIPTION
|

Save the current context in the structure variable

|

You can also get the current context from the global
|

variable
|

|

|
||||
However, simply access single elements in this structure
|

with the macros given in

.BR vgagl (7)
|
||||
but do not copy
|
||||
.I currentcontext
|
||||
in another structure. This is because the size of the structure
|
||||
might change and your program does not know it when it will be
|
||||
linked dynamically to future svgalib versions.
|
||||
|
||||
Instead use
|
||||
.BR gl_allocatecontext (3)
|
||||
to allocate such a structure, fill it with
|
||||
.B gl_getcontext
|
||||
and release it with
|

.BR free (3)
|
||||
after usage.

You should not assume that the same drawing trajectory is used when you exchange start and

To use this program one first sets up a mode with a regular
|
||||
vga_setmode call and vga_setpage(0), with possibly a
|
||||
vga_setlinearaddressing
|
||||
call. Then a call to gl_setcontextvga(mode) is made. This makes the
|
||||
information about the mode available to gl_line.
|
||||
|
||||
The pixels are placed directly into video memory using inline coded

||||
commands.

.TH gl_printf 3 "22 Feb 1997" "Svgalib 1.3.0" "Svgalib User Manual"
|
||||
.SH NAME
|
||||
gl_printf \- write formatted output in graphic mode
|
||||
|
||||
.SH SYNOPSIS
|
||||
.B #include <vgagl.h>
|
||||
|
||||
.BI "int gl_printf(int " x ", int " y ", const char *" fmt ", ...);"
|
||||
|
||||
.SH DESCRIPTION
|
||||
.B gl_printf
|
||||
writes, like
|
||||
.B printf(3)
|
||||
a formatted string to position
|
||||
.RI ( x ", " y )
|
||||
using the currently selected font. If one or both of
|
||||
.IR x " and " y
|
||||
is negative, the text printing continues at the last position. The
|
||||
special characters
|
||||
.BR \eb ", " \er ", "
|
||||
.BR \en ", " \ea ", "
|
||||
.BR \et " and " \ev
|
||||
have the usual effects.
|
||||
|
||||
Printing wraps at the screen borders. Nevertheless, behaviour is undefined
|
||||
if not a single characters fits on the screen or if the initial position
|
||||
is outside the screen.
|
||||
|
||||
The kind of text draw operation is set with
|
||||
.BR gl_setwritemode (3).
|
||||
|
||||
.B BEWARE!
|
||||
Prior to the of use of
|
||||
.BR gl_printf (3)
|
||||
you must set a font.
|
||||
|
||||
A good default initialization sequence is:
|
||||
|
||||
.B gl_setfont(8, 8, gl_font8x8);
|
||||
.br
|
||||
.B gl_setwritemode(FONT_COMPRESSED + WRITEMODE_OVERWRITE);
|
||||
.br
|
||||
.B gl_setfontcolors(0, vga_white());
|
||||
.br
|
||||
|
||||
.SH RETURN VALUE
|
||||
The number of characters printed.
|
||||
|
||||

.SH NAME
|

gl_putboxmask \- copy a masked pixmap to a rectangular area
|
||||
|

.SH SYNOPSIS
|

.B #include <vgagl.h>
|

|
||||
.BI "void gl_putboxmask(int " x ", int " y ", int " w ", int " h ", void *" dp );

|

Copy the contents of a memory buffer

This function works like
|

.BR gl_putbox ,
|
||||
but does not write pixmap pixels of color zero. If the same pixmap is used often
|
||||
you should consider using the faster
|
||||
.BR gl_putboxmaskcompiled (3).
|
||||
|
||||
Pixmaps are in row-major order. The source pixmap memory has the size
|
||||
.IR w " * " h " * "
