ATI 18800/28800 driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This is a software-only driver for the ATI 18800/28800 chipsets, based on
|
||||||
|
the native drivers from old versions of the Allegro library. It only
|
||||||
|
supports 256 color modes, and has no support for linear framebuffers or
|
||||||
|
accelerated drawing. As such it is useful primarily because it is faster
|
||||||
|
than the VESA 1.x bank switching mechanism, and as a workaround for the
|
||||||
|
many bugs in common VESA driver implementations.
|
||||||
|
|
||||||
|
This code is not portable to any platforms other than DOS+DPMI, because
|
||||||
|
it uses BIOS calls to set the initial video mode.

|
* hardware drawing operations so their coordinate system is relative
|

|
* to the active page. You must also maintain an offset from the start
|
||||||

|
* af_active_page*af_height onto the input Y coordinate of any accelerator

Avance Logic driver notes
|
||||||
|
|
||||||
|
|
||||||
|
Notes:
|
||||||
|
|
||||||
|
This is based upon the stub driver implementation, with
|
||||||
|
ALG-specific code added bit by bit.
|
||||||
|
|
||||||
|
Information on the Avance Logic range of cards is taken
|
||||||
|
from the VGADOC package.
|
||||||
|
|
||||||
|
As far as I know, this driver should support the following
|
||||||
|
cards:
|
||||||
|
|
||||||
|
ALG-2101, ALG-2201, ALG-2228, ALG-2301, ALG-2302
|
||||||
|
|
||||||
|
Some of these cards can provide hardware acceleration on
|
||||||
|
blits and lines, and a hardware cursor. Support for these
|
||||||
|
features is not yet implemented into this driver.
|
||||||
|
|
||||||
|
|
||||||
|
Special note for ALG-2101 and ALG-2302 users:
|
||||||
|
|
||||||
|
I'm not quite sure how to tell the difference between
|
||||||
|
ALG-2101 and ALG-2302; I have the latter but have found
|
||||||
|
no specific documentation about it. The documented
|
||||||
|
detection routines return ALG-2101. I have used an
|
||||||
|
underdocumented register to try to tell the difference,
|
||||||
|
but this might not work. If you have either of these
|
||||||
|
and the driver detects the wrong one, please let me know.
|
||||||
|
It won't affect the operation of the driver; it's just
|
||||||
|
nice when a program detects your hardware correctly.
|
||||||
|
|
||||||
|
|
||||||
|
History:
|
||||||
|
13/04/98 -- first version; just a copy of the stub driver.
|
||||||
|
|
||||||
|
15/04/98 -- removed VESA code, replaced with hardware-
|
||||||
|
level code.
|
||||||
|
|
||||||
|
20/04/98 -- finished implementing DrawScan, started lying
|
||||||
|
about supporting hardware acceleration, tested with
|
||||||
|
Allegro, corrected big bug in DrawScan.
|
||||||
|
|
||||||
|
01/11/98 -- Shawn Hargreaves removed hardware acceleration bodge: it
|
||||||
|
now admits that it is a dumb framebuffer driver :-)

/*
|
||||||
|
1 - the oldest BitBLT capable chips, !!for color-expand with transparency
|
||||||
|
transparent color is used !!, maxwidth 2047, maxpitch 4095, maxheight 1023,
|
||||||
|
all BitBLT registers except src&dstaddr are preserved, allow at most 7 bits
|
||||||
|
to be discarded with color expansion at the end of each scanline, color
|
||||||
|
expansion and hw cursor in 8 and 15/16bpp supported
|
||||||
|
2 - supports MMIO at b8000 or at the end of linear address space (2mb-256),
|
||||||
|
!!for color-expand with transparency 0 bits are just skipped!!, maxpitch 8191, color expansion
|
||||||
|
with left edge clipping&pattern vertical preset, supports color expanded
|
||||||
|
pattern polygon fills
|
||||||
|
3 - like 2, ? need srcaddr to be written for color expansion system to
|
||||||
|
screen ?, hw cursor also at 24/32bpp
|
||||||
|
4 - like 3, but 64 bit, maxwidth 8191, doesn't support clipping&vertical
|
||||||
|
preset and polygon fills, color expansion in 32bpp supported, for color
|
||||||
|
expansion with transparency all 4 bytes of fg color has to be written and 4
|
||||||
|
bytes of color has to be filled with not fg color, has bug in system to
|
||||||
|
display memory transfers, hw cursor also at 24/32bpp,
|
||||||
|
5 - the bug is corrected
|
||||||
|
6 - like 2, but 64 bit, maxwidth 8191, maxheight 2047,supports solid fill,
|
||||||
|
color expansion in 24 and 32bpp, for 24bpp color expansion transparency must
|
||||||
|
be enabled, but can invert the meaning of input data, so normal color
|
||||||
|
expansion can de done in two passes, has auto-start capability, hw cursor
|
||||||
|
also at 24/32bpp, triple buffer ?
|
||||||
|
7 - like 3 with video features
|
||||||
|
8 - like 9, no clipping, no X-Y pos.
|
||||||
|
9 - like 6, has clip rectangle, X-Y positioning, command list with possible
|
||||||
|
interrupt on completion, left edge clipping more complex, can probably triple
|
||||||
|
buffer, color expand with uses transparent color, no transparent mask
|
||||||
|
10 - (7541,7543) like 1, height is _not_ preserved
|
||||||
|
11 - (7542) don't know anything
|
||||||
|
12 - (7548) like 1 with MMIO, autostart, height is _not_ preserved
|
||||||
|
13 - (7555-6) like 6, MMIO in PCI 0x14 or offset 0x3fff00, triple buffer
|
||||||
|
GR16-17, no 32bpp color expansion, autostart
|
||||||
|
if banked GR6[3:2]=01,SR17[6]=0,SR17[7:4]=0
|
||||||
|
else SR17[6]=1,SR17[7:4]!=0

Cirrus 54x driver implementation notes.
|
||||||
|
|
||||||
|
Pattern fills may be improved quite a lot for cards which supports starting
|
||||||
|
on different place of pattern than upper left corner (now I always assume
|
||||||
|
accelerator can't do that so whenever upper left corner changes I change the
|
||||||
|
pattern). I also don't understand the notation of raster operations cirrus
|
||||||
|
supports and so SetMix isn't probably implemented properly.
|
||||||
|
|
||||||
|
Because of lack of precise specification of right input data to functions, some
|
||||||
|
of them may be implemented wrong.
|
||||||
|
|
||||||
|
Optimization with -O3 helps a bit, also port accesses are on RING 3 quite slow
|
||||||
|
so checking is the content of registers changed helped quite a bit. I expect
|
||||||
|
there might be quite a lot of problem with newer cirruses now, definitely
|
||||||
|
should work with 5426,5428,7541 and 7543.
|
||||||
|
|
||||||
|
***Note: Now also tested with a 5446 (rev A) and modified to work
|
||||||
|
(Keir Fraser, email: kaf24@cam.ac.uk)
|
||||||
|
I have had some problems with the memory-mapped IO, specifically when the
|
||||||
|
registers are mapped to low memory (0xb8000). If you are having problems
|
||||||
|
getting the driver to work, you can disable MMIO by uncommenting the
|
||||||
|
DISABLE_MMIO line at the top of driver.c. You should also contact me at
|
||||||
|
the email address given above to look for a more permanent solution!

Introduction
|
||||||
|
|
||||||
|
VBE/AF is a low level driver interface for accessing graphics hardware.
|
||||||
|
It provides all the same features as VESA 3.0 (access to linear
|
||||||
|
framebuffer video memory, high speed protected mode bank switching, page
|
||||||
|
flipping, hardware scrolling, etc), and adds the ability to use 2D
|
||||||
|
hardware acceleration in an efficient and portable manner. An /AF driver
|
||||||
|
is provided as a disk file (vbeaf.drv), and contains clean 32 bit machine
|
||||||
|
code which can be called directly by a C program. If implemented
|
||||||
|
correctly, these drivers have the potential to be binary portable across
|
||||||
|
multiple operating systems, so the same driver file can be used from DOS,
|
||||||
|
Windows, Linux, etc.
|
||||||
|
|
||||||
|
FreeBE/AF is an attempt to implement free VBE/AF drivers on as many cards
|
||||||
|
as possible. This idea came about on the Allegro mailing list, due to the
|
||||||
|
need for a dynamically loadable driver structure that could support
|
||||||
|
hardware acceleration. VBE/AF seemed to fit the bill, and Allegro already
|
||||||
|
had support for the SciTech drivers, so it seemed like a good idea to
|
||||||
|
adopt this format for ourselves. The primary goal is to make these
|
||||||
|
drivers work with Allegro, so the emphasis will be on implementing the
|
||||||
|
functions that Allegro actually uses, but we encourage other developers
|
||||||
|
to join us in taking advantage of this excellent driver architecture.
|
||||||
|
|
||||||
|
This project currently provides fully accelerated drivers for a handful
|
||||||
|
of chipsets, plus a number of dumb framebuffer implementations based on
|
||||||
|
the video drivers from older versions of the Allegro library. It has also
|
||||||
|
defined a few extensions to the stock VBE/AF API, which allow Allegro
|
||||||
|
programs to use these drivers in a true protected mode environment
|
||||||
|
without having to resort to the nearptr hack, and provide a number of
|
||||||
|
hook functions that will be needed to remain compatible with future
|
||||||
|
generations of the SciTech drivers.
|
||||||
|
|
||||||
|
The current status of the VBE/AF standard is somewhat confused. It was
|
||||||
|
designed by SciTech Software (<a href="http://www.scitechsoft.com/">http://www.scitechsoft.com/</a>), who provide
|
||||||
|
commercial VBE/AF drivers for a wide range of cards as part of their
|
||||||
|
Display Doctor package. It was originally going to be released as a VESA
|
||||||
|
standard, but the VESA people seriously messed this up by charging
|
||||||
|
exorbitant sums of $$$ for copies of the spec. As a result, very few
|
||||||
|
people bothered to support these drivers, and the FreeBE/AF project was
|
||||||
|
only made possible by the information available in the SciTech MGL
|
||||||
|
library source code, and the helpfulness of Kendall Bennett (the designer
|
||||||
|
of the spec) himself. Unfortunately SciTech have now abandoned VBE/AF
|
||||||
|
themselves, replacing it with an equivalent but non-public API called
|
||||||
|
Nucleus, which is only available under NDA. SciTech will continue to
|
||||||
|
provide VBE/AF drivers for the cards which they already support, but
|
||||||
|
will not adding any new ones in the future, so this project is now the
|
||||||
|
only active source of VBE/AF driver implementations.
|
||||||
|
|
||||||
|
At present, the Allegro (<a href="http://www.talula.demon.co.uk/allegro/">http://www.talula.demon.co.uk/allegro/</a>) and MGL
|
||||||
|
(<a href="http://www.scitechsoft.com">http://www.scitechsoft.com</a>) libraries are the only major packages which
|
||||||
|
can take advantage of accelerated VBE/AF drivers. As such, this project
|
||||||
|
is starting to look more like a implementation of video drivers
|
||||||
|
specifically for the Allegro library, rather than a potential
|
||||||
|
industry-wide standard :-) But it doesn't have to be this way! VBE/AF is
|
||||||
|
technically an excellent design: efficient, easy to write and use, and
|
||||||
|
highly portable. If you are writing graphics code, and getting frustrated
|
||||||
|
by the many limitiations imposed by VESA, why not think about using
|
||||||
|
VBE/AF instead? Even better, if you have a card that our project doesn't
|
||||||
|
yet support, why not add a new driver for it? This can be a lot of fun,
|
||||||
|
and we would be delighted to offer any help or advice that you might need.

Usage
|
||||||
|
|
||||||
|
Each driver is located in a different subdirectory. Run "make" to compile
|
||||||
|
them, choose the one you want, copy the vbeaf.drv file from this
|
||||||
|
directory to c:\, and you are ready to go!

|
The stub directory contains a generic non-accelerated VBE/AF driver. This
|
||||||
|
is not useful in any way, because it simply sits on top of your existing
|
||||||
|
VESA driver and emulates a few "hardware" drawing operations with very
|
||||||
|
slow software implementations. The stub is intended as a starting point
|
||||||
|
for people who want to make drivers for a specific card, and should not
|
||||||
|
be used directly.
|
||||||
|
|
||||||
|
To recompile FreeBE/AF, you need a working copy of djgpp. Run "make" to
|
||||||
|
build all the available drivers, or "make dir/vbeaf.drv" to compile a
|
||||||
|
specific driver (replacing {dir} with the directory name, eg. "make
|
||||||
|
stub/vbeaf.drv"). To build the install.exe program for a binary
|
||||||
|
distribution, run "make all" (this requires you to have the Allegro
|
||||||
|
library installed, and the allegro/tools/ directory in your path). This
|
||||||
|
documentation is converted from the custom ._tx format into ASCII and
|
||||||
|
HTML by the Allegro makedoc program: run "make docs" to do this, after
|
||||||
|
putting the makedoc utility somewhere in your path.
|
||||||
|
|
||||||
|
FreeBE/AF only supports the VBE/AF 2.0 API. It is not backward compatible
|
||||||
|
with the assembler VBE/AF 1.0 interface, and programs that try to use
|
||||||
|
those obsolete functions will not work correctly.

Supported Hardware
|
||||||
|
|
||||||
|
Not all VBE/AF drivers provide the complete set of possible features.
|
||||||
|
Some may be written in a 100% clean and portable manner, allowing them to
|
||||||
|
be used on any platform, but others make use of the video BIOS in order
|
||||||
|
to set the initial video mode: this makes them a lot easier to write, but
|
||||||
|
means that it can only be used under DOS. Some of the drivers, in
|
||||||
|
particular the ones based on the old Allegro library chipset support,
|
||||||
|
don't support any hardware accelerated drawing at all: these are still
|
||||||
|
usefull because they provide high speed protected mode bank switching and
|
||||||
|
can work around the bugs in some manufacturer's VESA implementations, but
|
||||||
|
are obviously not nearly as cool as a fully accelerated driver.
|
||||||
|

If you want to add a new driver, follow these steps:
|
||||||
|
<pre>
|
||||||
|
md cardname
|
||||||
|
copy stub\*.* cardname
|
||||||
|
edit makefile
|
||||||
|
{ add a new entry to the DRIVERS variable at the top of the file }
|
||||||
|
cd cardname
|
||||||
|
edit drvhdr.c
|
||||||
|
{ replace "stub driver implementation" with your driver name }
|
||||||
|
edit driver.c
|
||||||
|
{ fill in the blanks, replacing the VESA calls with chipset-specific }
|
||||||
|
{ code, and fleshing out the accelerated drawing functions }
|
||||||
|
edit notes.txt
|
||||||
|
{ describe anything interesting about your driver, most importantly }
|
||||||
|
{ listing what drawing functions it supports in hardware }
|
||||||
|
cd..
|
||||||
|
done!
|
||||||
|
</pre>
|
||||||
|
The makefile requires each driver to provide a drvhdr.c file, which will
|
||||||
|
be linked into the drvgen.exe utility and used to generate the VBE/AF
|
||||||
|
header. You must also provide a notes.txt, which will be displayed by the
|
||||||
|
installation program, but everything else is entirely up to you. Any C
|
||||||
|
source files placed into your driver directory will automatically be
|
||||||
|
compiled and linked into the driver binary, so you can organise your code
|
||||||
|
in whatever style you prefer.
|
||||||
|
|
||||||
|
Because the VBE/AF drivers are output as relocatable binary modules, they
|
||||||
|
cannot use any C library functions. There are a few utility functions in
|
||||||
|
helper.c, but these will not work on any platforms other than DOS+DPMI,
|
||||||
|
so it would be better to avoid using them if you can manage without.
|
||||||
|
|
||||||
|
A great deal of hardware information can be found in the VGADOC package
|
||||||
|
(<a href="ftp://x2ftp.oulu.fi/pub/msdos/programming/docs/vgadoc4b.zip">ftp://x2ftp.oulu.fi/pub/msdos/programming/docs/vgadoc4b.zip</a>) and the
|
||||||
|
XFree86 sources (<a href="http://www.xfree86.org/">http://www.xfree86.org/</a>). If this isn't enough, try
|
||||||
|
asking the manufacturer for more details.

History
|
||||||
|
|
||||||
|
30 March, 1998 - v0.1.
|
||||||
|
First public release, containing an example driver implementation that
|
||||||
|
runs on top of VESA.
|
||||||
|
|
||||||
|
31 March, 1998 - v0.11.
|
||||||
|
Added support for multi-buffered modes.
|
||||||
|
|
||||||
|
5 April, 1998 - v0.2.
|
||||||
|
Added an accelerated Matrox driver.
|
||||||
|
|
||||||
|
8 April, 1998 - v0.3.
|
||||||
|
Added accelerated drivers for ATI mach64 and Cirrus 54x cards, plus
|
||||||
|
minor updates to the Matrox driver.
|
||||||
|
|
||||||
|
12 April, 1998 - v0.4.
|
||||||
|
Proper installation program, more drawing functions implemented by the
|
||||||
|
stub and Matrox drivers, improved ATI driver, compiled with PGCC for a
|
||||||
|
5% speed boost.
|
||||||
|
|
||||||
|
26 April, 1998 - v0.5.
|
||||||
|
More accelerated features in the Cirrus and ATI drivers. Fixed bugs in
|
||||||
|
the Matrox driver. Added an option to disable hardware emulation in
|
||||||
|
the stub driver, which produces a non-accelerated, dumb framebuffer
|
||||||
|
implementation. The init code will now politely fail any programs that
|
||||||
|
try to use VBE/AF 1.0 functions, rather than just crashing.
|
||||||
|
|
||||||
|
10 June, 1998 - v0.6.
|
||||||
|
Fixed scrolling problem on Millenium cards.
|
||||||
|
|
||||||
|
1 November, 1998 - v0.7.
|
||||||
|
Added drivers for Trident TGUI 9440 and Avance Logic cards, and
|
||||||
|
improved the build process.
|
||||||
|
|
||||||
|
14 December, 1998 - v0.8.
|
||||||
|
Bugfixes to the Matrox Millenium II and Cirrus drivers. Converted all
|
||||||
|
the old Allegro library chipset drivers into non-accelerated VBE/AF
|
||||||
|
format, adding support for ATI 18800/28800, Paradise, S3, Trident,
|
||||||
|
Tseng ET3000/ET4000/ET6000, and Video-7 boards. Designed and
|
||||||
|
implemented an API extension mechanism, providing the ability to use
|
||||||
|
these drivers in a true protected mode environment, a more rational
|
||||||
|
relocation scheme, and various hooks that will later be needed for
|
||||||
|
supporting the SciTech Nucleus drivers.
|
||||||
|
|
||||||
|
20 December, 1998 - v0.9.
|
||||||
|
Bugfixes. Added a config mechanism, allowing the install program to
|
||||||
|
optionally disable some features of a driver.
|
||||||
|
|
||||||
|
3 January, 1999 - v1.0
|
||||||
|
Bugfixes.
|
||||||
|
|
||||||
|
27 March, 1999 - v1.1
|
||||||
|
Added acceleration support to the S3 driver, plus some bugfixes.
|
||||||
|
|
||||||
|
27 June, 1999 - v1.2
|
||||||
|
Added driver for NVidia cards. Improved the PCI bus scanning code to
|
||||||
|
know about bridges to secondary devices (so it can locate AGP cards).
|
||||||
|
Minor bugfix to the Mach64 driver (it was using the wrong clip rect
|
||||||
|
for scrolling displays). Minor bugfix to the Matrox driver (it was
|
||||||
|
setting the wrong background color for the hardware cursor).

<h1><a name="Introduction">Introduction</a></h1>
|
||||||
|
<p>
|
||||||
|
VBE/AF is a low level driver interface for accessing graphics hardware.
|
||||||
|
It provides all the same features as VESA 3.0 (access to linear
|
||||||
|
framebuffer video memory, high speed protected mode bank switching, page
|
||||||
|
flipping, hardware scrolling, etc), and adds the ability to use 2D
|
||||||
|
hardware acceleration in an efficient and portable manner. An /AF driver
|
||||||
|
is provided as a disk file (vbeaf.drv), and contains clean 32 bit machine
|
||||||
|
code which can be called directly by a C program. If implemented
|
||||||
|
correctly, these drivers have the potential to be binary portable across
|
||||||
|
multiple operating systems, so the same driver file can be used from DOS,
|
||||||
|
Windows, Linux, etc.
|
||||||
|
<p>
|
||||||
|
FreeBE/AF is an attempt to implement free VBE/AF drivers on as many cards
|
||||||
|
as possible. This idea came about on the Allegro mailing list, due to the
|
||||||
|
need for a dynamically loadable driver structure that could support
|
||||||
|
hardware acceleration. VBE/AF seemed to fit the bill, and Allegro already
|
||||||
|
had support for the SciTech drivers, so it seemed like a good idea to
|
||||||
|
adopt this format for ourselves. The primary goal is to make these
|
||||||
|
drivers work with Allegro, so the emphasis will be on implementing the
|
||||||
|
functions that Allegro actually uses, but we encourage other developers
|
||||||
|
to join us in taking advantage of this excellent driver architecture.
|
||||||
|
<p>
|
||||||
|
This project currently provides fully accelerated drivers for a handful
|
||||||
|
of chipsets, plus a number of dumb framebuffer implementations based on
|
||||||
|
the video drivers from older versions of the Allegro library. It has also
|
||||||
|
defined a few extensions to the stock VBE/AF API, which allow Allegro
|
||||||
|
programs to use these drivers in a true protected mode environment
|
||||||
|
without having to resort to the nearptr hack, and provide a number of
|
||||||
|
hook functions that will be needed to remain compatible with future
|
||||||
|
generations of the SciTech drivers.
|
||||||
|
<p>
|
||||||
|
The current status of the VBE/AF standard is somewhat confused. It was
|
||||||
|
designed by SciTech Software (<a href="http://www.scitechsoft.com/">http://www.scitechsoft.com/</a>), who provide
|
||||||
|
commercial VBE/AF drivers for a wide range of cards as part of their
|
||||||
|
Display Doctor package. It was originally going to be released as a VESA
|
||||||
|
standard, but the VESA people seriously messed this up by charging
|
||||||
|
exorbitant sums of $$$ for copies of the spec. As a result, very few
|
||||||
|
people bothered to support these drivers, and the FreeBE/AF project was
|
||||||
|
only made possible by the information available in the SciTech MGL
|
||||||
|
library source code, and the helpfulness of Kendall Bennett (the designer
|
||||||
|
of the spec) himself. Unfortunately SciTech have now abandoned VBE/AF
|
||||||
|
themselves, replacing it with an equivalent but non-public API called
|
||||||
|
Nucleus, which is only available under NDA. SciTech will continue to
|
||||||
|
provide VBE/AF drivers for the cards which they already support, but
|
||||||
|
will not adding any new ones in the future, so this project is now the
|
||||||
|
only active source of VBE/AF driver implementations.
|
||||||
|
<p>
|
||||||
|
At present, the Allegro (<a href="http://www.talula.demon.co.uk/allegro/">http://www.talula.demon.co.uk/allegro/</a>) and MGL
|
||||||
|
(<a href="http://www.scitechsoft.com">http://www.scitechsoft.com</a>) libraries are the only major packages which
|
||||||
|
can take advantage of accelerated VBE/AF drivers. As such, this project
|
||||||
|
is starting to look more like a implementation of video drivers
|
||||||
|
specifically for the Allegro library, rather than a potential
|
||||||
|
industry-wide standard :-) But it doesn't have to be this way! VBE/AF is
|
||||||
|
technically an excellent design: efficient, easy to write and use, and
|
||||||
|
highly portable. If you are writing graphics code, and getting frustrated
|
||||||
|
by the many limitiations imposed by VESA, why not think about using
|
||||||
|
VBE/AF instead? Even better, if you have a card that our project doesn't
|
||||||
|
yet support, why not add a new driver for it? This can be a lot of fun,
|
||||||
|
and we would be delighted to offer any help or advice that you might need.

|
<p>
|
||||||
|
Each driver is located in a different subdirectory. Run "make" to compile
|
||||||
|
them, choose the one you want, copy the vbeaf.drv file from this
|
||||||
|
directory to c:\, and you are ready to go!
|
||||||
|
<p>
|
||||||
|
The stub directory contains a generic non-accelerated VBE/AF driver. This
|
||||||
|
is not useful in any way, because it simply sits on top of your existing
|
||||||
|
VESA driver and emulates a few "hardware" drawing operations with very
|
||||||
|
slow software implementations. The stub is intended as a starting point
|
||||||
|
for people who want to make drivers for a specific card, and should not
|
||||||
|
be used directly.
|
||||||
|
<p>
|
||||||
|
To recompile FreeBE/AF, you need a working copy of djgpp. Run "make" to
|
||||||
|
build all the available drivers, or "make dir/vbeaf.drv" to compile a
|
||||||
|
specific driver (replacing {dir} with the directory name, eg. "make
|
||||||
|
stub/vbeaf.drv"). To build the install.exe program for a binary
|
||||||
|
distribution, run "make all" (this requires you to have the Allegro
|
||||||
|
library installed, and the allegro/tools/ directory in your path). This
|
||||||
|
documentation is converted from the custom ._tx format into ASCII and
|
||||||
|
HTML by the Allegro makedoc program: run "make docs" to do this, after
|
||||||
|
putting the makedoc utility somewhere in your path.
|
||||||
|
<p>
|
||||||
|
FreeBE/AF only supports the VBE/AF 2.0 API. It is not backward compatible
|
||||||
|
with the assembler VBE/AF 1.0 interface, and programs that try to use
|
||||||
|
those obsolete functions will not work correctly.

<h1><a name="Supported Hardware">Supported Hardware</a></h1>
|
||||||
|
<p>
|
||||||
|
Not all VBE/AF drivers provide the complete set of possible features.
|
||||||
|
Some may be written in a 100% clean and portable manner, allowing them to
|
||||||
|
be used on any platform, but others make use of the video BIOS in order
|
||||||
|
to set the initial video mode: this makes them a lot easier to write, but
|
||||||
|
means that it can only be used under DOS. Some of the drivers, in
|
||||||
|
particular the ones based on the old Allegro library chipset support,
|
||||||
|
don't support any hardware accelerated drawing at all: these are still
|
||||||
|
usefull because they provide high speed protected mode bank switching and
|
||||||
|
can work around the bugs in some manufacturer's VESA implementations, but
|
||||||
|
are obviously not nearly as cool as a fully accelerated driver.

If you want to add a new driver, follow these steps:
|
||||||
|
<p><pre>
|
||||||
|
md cardname
|
||||||
|
copy stub\*.* cardname
|
||||||
|
edit makefile
|
||||||
|
{ add a new entry to the DRIVERS variable at the top of the file }
|
||||||
|
cd cardname
|
||||||
|
edit drvhdr.c
|
||||||
|
{ replace "stub driver implementation" with your driver name }
|
||||||
|
edit driver.c
|
||||||
|
{ fill in the blanks, replacing the VESA calls with chipset-specific }
|
||||||
|
{ code, and fleshing out the accelerated drawing functions }
|
||||||
|
edit notes.txt
|
||||||
|
{ describe anything interesting about your driver, most importantly }
|
||||||
|
{ listing what drawing functions it supports in hardware }
|
||||||
|
cd..
|
||||||
|
done!
|
||||||
|
<p></pre>
|
||||||
|
The makefile requires each driver to provide a drvhdr.c file, which will
|
||||||
|
be linked into the drvgen.exe utility and used to generate the VBE/AF
|
||||||
|
header. You must also provide a notes.txt, which will be displayed by the
|
||||||
|
installation program, but everything else is entirely up to you. Any C
|
||||||
|
source files placed into your driver directory will automatically be
|
||||||
|
compiled and linked into the driver binary, so you can organise your code
|
||||||
|
in whatever style you prefer.
|
||||||
|
<p>
|
||||||
|
Because the VBE/AF drivers are output as relocatable binary modules, they
|
||||||
|
cannot use any C library functions. There are a few utility functions in
|
||||||
|
helper.c, but these will not work on any platforms other than DOS+DPMI,
|
||||||
|
so it would be better to avoid using them if you can manage without.

||||||

|
30 March, 1998 - v0.1.
|
||||||
|
First public release, containing an example driver implementation that
|
||||||
|
runs on top of VESA.
|
||||||
|
<p>
|
||||||
|
31 March, 1998 - v0.11.
|
||||||
|
Added support for multi-buffered modes.
|
||||||
|
<p>
|
||||||
|
5 April, 1998 - v0.2.
|
||||||
|
Added an accelerated Matrox driver.
|
||||||
|
<p>
|
||||||
|
8 April, 1998 - v0.3.
|
||||||
|
Added accelerated drivers for ATI mach64 and Cirrus 54x cards, plus
|
||||||
|
minor updates to the Matrox driver.
|
||||||
|
<p>
|
||||||
|
12 April, 1998 - v0.4.
|
||||||
|
Proper installation program, more drawing functions implemented by the
|
||||||
|
stub and Matrox drivers, improved ATI driver, compiled with PGCC for a
|
||||||
|
5% speed boost.
|
||||||
|
<p>
|
||||||
|
26 April, 1998 - v0.5.

|
the Matrox driver. Added an option to disable hardware emulation in
|
||||||
|
the stub driver, which produces a non-accelerated, dumb framebuffer
|
||||||
|
implementation. The init code will now politely fail any programs that
|
||||||
|
try to use VBE/AF 1.0 functions, rather than just crashing.

||||||
|
10 June, 1998 - v0.6.
|
||||||
|

||||||
|
Tseng ET3000/ET4000/ET6000, and Video-7 boards. Designed and
|
||||||
|
implemented an API extension mechanism, providing the ability to use
|
||||||
|
these drivers in a true protected mode environment, a more rational
|
||||||
|
relocation scheme, and various hooks that will later be needed for
|
||||||
|
supporting the SciTech Nucleus drivers.
|
||||||
|
<p>
|
||||||
|
20 December, 1998 - v0.9.
|
||||||
|
Bugfixes. Added a config mechanism, allowing the install program to
|
||||||
|
optionally disable some features of a driver.
|
||||||
|
<p>
|
||||||
|
3 January, 1999 - v1.0
|
||||||
|
Bugfixes.
|
||||||
|
<p>
|
||||||
|
27 March, 1999 - v1.1
|
||||||
|
Added acceleration support to the S3 driver, plus some bugfixes.
|
||||||
|
<p>
|
||||||
|
27 June, 1999 - v1.2
|
||||||
|
Added driver for NVidia cards. Improved the PCI bus scanning code to
|
||||||
|
know about bridges to secondary devices (so it can locate AGP cards).
|
||||||
|
Minor bugfix to the Mach64 driver (it was using the wrong clip rect
|
||||||
|
for scrolling displays). Minor bugfix to the Matrox driver (it was
|
||||||
|
setting the wrong background color for the hardware cursor).

The free VBE/AF driver project, version 1.2

"The nice thing about standards is that
|
||||||
|
there are so many of them to choose from."

||||||

||||||

|
||||||

||||||
|
======================================
|
||||||
|
============ Introduction ============
|
||||||
|
======================================
|
||||||
|
|
||||||
|
VBE/AF is a low level driver interface for accessing graphics hardware.
|
||||||
|
It provides all the same features as VESA 3.0 (access to linear
|
||||||
|
framebuffer video memory, high speed protected mode bank switching, page
|
||||||
|
flipping, hardware scrolling, etc), and adds the ability to use 2D
|
||||||
|
hardware acceleration in an efficient and portable manner. An /AF driver
|
||||||
|
is provided as a disk file (vbeaf.drv), and contains clean 32 bit machine
|
||||||
|
code which can be called directly by a C program. If implemented
|
||||||
|
correctly, these drivers have the potential to be binary portable across
|
||||||
|
multiple operating systems, so the same driver file can be used from DOS,
|
||||||
|
Windows, Linux, etc.
|
||||||
|
|
||||||
|
FreeBE/AF is an attempt to implement free VBE/AF drivers on as many cards
|
||||||
|
as possible. This idea came about on the Allegro mailing list, due to the
|
||||||
|
need for a dynamically loadable driver structure that could support
|
||||||
|
hardware acceleration. VBE/AF seemed to fit the bill, and Allegro already
|
||||||
|
had support for the SciTech drivers, so it seemed like a good idea to
|
||||||
|
adopt this format for ourselves. The primary goal is to make these
|
||||||
|
drivers work with Allegro, so the emphasis will be on implementing the
|
||||||
|
functions that Allegro actually uses, but we encourage other developers
|
||||||
|
to join us in taking advantage of this excellent driver architecture.
|
||||||
|
|
||||||
|
This project currently provides fully accelerated drivers for a handful
|
||||||
|
of chipsets, plus a number of dumb framebuffer implementations based on
|
||||||
|
the video drivers from older versions of the Allegro library. It has also
|
||||||
|
defined a few extensions to the stock VBE/AF API, which allow Allegro
|
||||||
|
programs to use these drivers in a true protected mode environment
|
||||||
|
without having to resort to the nearptr hack, and provide a number of
|
||||||
|
hook functions that will be needed to remain compatible with future
|
||||||
|
generations of the SciTech drivers.
|
||||||
|
|
||||||
|
The current status of the VBE/AF standard is somewhat confused. It was
|
||||||
|
designed by SciTech Software (http://www.scitechsoft.com/), who provide
|
||||||
|
commercial VBE/AF drivers for a wide range of cards as part of their
|
||||||
|
Display Doctor package. It was originally going to be released as a VESA
|
||||||
|
standard, but the VESA people seriously messed this up by charging
|
||||||
|
exorbitant sums of $$$ for copies of the spec. As a result, very few
|
||||||
|
people bothered to support these drivers, and the FreeBE/AF project was
|
||||||
|
only made possible by the information available in the SciTech MGL
|
||||||
|
library source code, and the helpfulness of Kendall Bennett (the designer
|
||||||
|
of the spec) himself. Unfortunately SciTech have now abandoned VBE/AF
|
||||||
|
themselves, replacing it with an equivalent but non-public API called
|
||||||
|
Nucleus, which is only available under NDA. SciTech will continue to
|
||||||
|
provide VBE/AF drivers for the cards which they already support, but
|
||||||
|
will not adding any new ones in the future, so this project is now the
|
||||||
|
only active source of VBE/AF driver implementations.
|
||||||
|
|
||||||
|
At present, the Allegro (http://www.talula.demon.co.uk/allegro/) and MGL
|
||||||
|
(http://www.scitechsoft.com) libraries are the only major packages which
|
||||||
|
can take advantage of accelerated VBE/AF drivers. As such, this project
|
||||||
|
is starting to look more like a implementation of video drivers
|
||||||
|
specifically for the Allegro library, rather than a potential
|
||||||
|
industry-wide standard :-) But it doesn't have to be this way! VBE/AF is
|
||||||
|
technically an excellent design: efficient, easy to write and use, and
|
||||||
|
highly portable. If you are writing graphics code, and getting frustrated
|
||||||
|
by the many limitiations imposed by VESA, why not think about using
|
||||||
|
VBE/AF instead? Even better, if you have a card that our project doesn't
|
||||||
|
yet support, why not add a new driver for it? This can be a lot of fun,
|
||||||
|
and we would be delighted to offer any help or advice that you might need.

===============================
|
||||||
|
============ Usage ============
|
||||||
|
===============================
|
||||||
|
|
||||||
|
Each driver is located in a different subdirectory. Run "make" to compile
|
||||||
|
them, choose the one you want, copy the vbeaf.drv file from this
|
||||||
|
directory to c:\, and you are ready to go!
|
||||||
|
|
||||||
|
The stub directory contains a generic non-accelerated VBE/AF driver. This
|
||||||
|
is not useful in any way, because it simply sits on top of your existing
|
||||||
|
VESA driver and emulates a few "hardware" drawing operations with very
|
||||||
|
slow software implementations. The stub is intended as a starting point
|
||||||
|
for people who want to make drivers for a specific card, and should not
|
||||||
|
be used directly.
|
||||||
|
|
||||||
|
To recompile FreeBE/AF, you need a working copy of djgpp. Run "make" to
|
||||||
|
build all the available drivers, or "make dir/vbeaf.drv" to compile a
|
||||||
|
specific driver (replacing {dir} with the directory name, eg. "make
|
||||||
|
stub/vbeaf.drv"). To build the install.exe program for a binary
|
||||||
|
distribution, run "make all" (this requires you to have the Allegro
|
||||||
|
library installed, and the allegro/tools/ directory in your path). This
|
||||||
|
documentation is converted from the custom ._tx format into ASCII and
|
||||||
|
HTML by the Allegro makedoc program: run "make docs" to do this, after
|
||||||
|
putting the makedoc utility somewhere in your path.
|
||||||
|
|
||||||
|
FreeBE/AF only supports the VBE/AF 2.0 API. It is not backward compatible
|
||||||
|
with the assembler VBE/AF 1.0 interface, and programs that try to use
|
||||||
|
those obsolete functions will not work correctly.
|
||||||
|
|
||||||
|

||||||

============================================
|
||||||
|
============ Supported Hardware ============
|
||||||
|
============================================
|
||||||
|
|
||||||
|
Not all VBE/AF drivers provide the complete set of possible features.
|
||||||
|
Some may be written in a 100% clean and portable manner, allowing them to
|
||||||
|
be used on any platform, but others make use of the video BIOS in order
|
||||||
|
to set the initial video mode: this makes them a lot easier to write, but
|
||||||
|
means that it can only be used under DOS. Some of the drivers, in
|
||||||
|
particular the ones based on the old Allegro library chipset support,
|
||||||
|
don't support any hardware accelerated drawing at all: these are still
|
||||||
|
usefull because they provide high speed protected mode bank switching and
|
||||||
|
can work around the bugs in some manufacturer's VESA implementations, but
|
||||||
|
are obviously not nearly as cool as a fully accelerated driver.

If you want to add a new driver, follow these steps:
|
||||||
|
|
||||||
|
md cardname
|
||||||
|
copy stub\*.* cardname
|
||||||
|
edit makefile
|
||||||
|
{ add a new entry to the DRIVERS variable at the top of the file }
|
||||||
|
cd cardname
|
||||||
|
edit drvhdr.c
|
||||||
|
{ replace "stub driver implementation" with your driver name }
|
||||||
|
edit driver.c
|
||||||
|
{ fill in the blanks, replacing the VESA calls with chipset-specific }
|
||||||
|
{ code, and fleshing out the accelerated drawing functions }
|
||||||
|
edit notes.txt
|
||||||
|
{ describe anything interesting about your driver, most importantly }
|
||||||
|
{ listing what drawing functions it supports in hardware }
|
||||||
|
cd..
|
||||||
|
done!
|
||||||
|
|
||||||
|
The makefile requires each driver to provide a drvhdr.c file, which will
|
||||||
|
be linked into the drvgen.exe utility and used to generate the VBE/AF
|
||||||
|
header. You must also provide a notes.txt, which will be displayed by the
|
||||||
|
installation program, but everything else is entirely up to you. Any C
|
||||||
|
source files placed into your driver directory will automatically be
|
||||||
|
compiled and linked into the driver binary, so you can organise your code
|
||||||
|
in whatever style you prefer.
|
||||||
|
|
||||||
|
Because the VBE/AF drivers are output as relocatable binary modules, they
|
||||||
|
cannot use any C library functions. There are a few utility functions in
|
||||||
|
helper.c, but these will not work on any platforms other than DOS+DPMI,
|
||||||
|
so it would be better to avoid using them if you can manage without.
|
||||||
|
|
||||||
|
A great deal of hardware information can be found in the VGADOC package
|
||||||
|
(ftp://x2ftp.oulu.fi/pub/msdos/programming/docs/vgadoc4b.zip) and the
|
||||||
|
XFree86 sources (http://www.xfree86.org/). If this isn't enough, try
|
||||||
|
asking the manufacturer for more details.

As the name implies, FreeBE/AF is free. Both the driver binaries and

sources may be distributed and modified without restriction. If you find

any of this stuff useful, the best way to repay us is by writing a new

|
driver for a card that isn't currently supported.

The Video Electronics Standards Association does _not_ deserve any

mention here. The absurd prices they charge for copies of the /AF

specification have prevented it from being widely supported, and I think
|

this is a great pity. Long live freedom!

============ History ============
|
||||||
|
=================================
|
||||||
|
|
||||||
|
30 March, 1998 - v0.1.
|
||||||
|
First public release, containing an example driver implementation that
|
||||||
|
runs on top of VESA.
|
||||||
|
|
||||||
|
31 March, 1998 - v0.11.
|
||||||
|
Added support for multi-buffered modes.
|
||||||
|
|
||||||
|
5 April, 1998 - v0.2.
|
||||||
|
Added an accelerated Matrox driver.
|
||||||
|
|
||||||
|
8 April, 1998 - v0.3.
|
||||||
|
Added accelerated drivers for ATI mach64 and Cirrus 54x cards, plus
|
||||||
|
minor updates to the Matrox driver.
|
||||||
|
|
||||||
|
12 April, 1998 - v0.4.
|
||||||
|
Proper installation program, more drawing functions implemented by the
|
||||||
|
stub and Matrox drivers, improved ATI driver, compiled with PGCC for a
|
||||||
|
5% speed boost.
|
||||||
|
|
||||||
|
26 April, 1998 - v0.5.
|
||||||
|
More accelerated features in the Cirrus and ATI drivers. Fixed bugs in
|
||||||
|
the Matrox driver. Added an option to disable hardware emulation in
|
||||||
|
the stub driver, which produces a non-accelerated, dumb framebuffer
|
||||||
|
implementation. The init code will now politely fail any programs that
|
||||||
|
try to use VBE/AF 1.0 functions, rather than just crashing.
|
||||||
|
|
||||||
|
10 June, 1998 - v0.6.
|
||||||
|
Fixed scrolling problem on Millenium cards.
|
||||||
|
|
||||||
|
1 November, 1998 - v0.7.
|
||||||
|
Added drivers for Trident TGUI 9440 and Avance Logic cards, and
|
||||||
|
improved the build process.
|
||||||
|
|
||||||
|
14 December, 1998 - v0.8.
|
||||||
|
Bugfixes to the Matrox Millenium II and Cirrus drivers. Converted all
|
||||||
|
the old Allegro library chipset drivers into non-accelerated VBE/AF
|
||||||
|
format, adding support for ATI 18800/28800, Paradise, S3, Trident,
|
||||||
|
Tseng ET3000/ET4000/ET6000, and Video-7 boards. Designed and
|
||||||
|
implemented an API extension mechanism, providing the ability to use
|
||||||
|
these drivers in a true protected mode environment, a more rational
|
||||||
|
relocation scheme, and various hooks that will later be needed for
|
||||||
|
supporting the SciTech Nucleus drivers.
|
||||||
|
|
||||||
|
20 December, 1998 - v0.9.
|
||||||
|
Bugfixes. Added a config mechanism, allowing the install program to
|
||||||
|
optionally disable some features of a driver.
|
||||||
|
|
||||||
|
3 January, 1999 - v1.0
|
||||||
|
Bugfixes.
|
||||||
|
|
||||||
|
27 March, 1999 - v1.1
|
||||||
|
Added acceleration support to the S3 driver, plus some bugfixes.
|
||||||
|
|
||||||
|
27 June, 1999 - v1.2
|
||||||
|
Added driver for NVidia cards. Improved the PCI bus scanning code to
|
||||||
|
know about bridges to secondary devices (so it can locate AGP cards).
|
||||||
|
Minor bugfix to the Mach64 driver (it was using the wrong clip rect
|
||||||
|
for scrolling displays). Minor bugfix to the Matrox driver (it was
|
||||||
|
setting the wrong background color for the hardware cursor).

ATI mach64 driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This driver is currently a limited implementation of VBE/AF for mach64.
|
||||||
|
It is not very well tested and may not work for you (if it doesn't,
|
||||||
|
give me your system description and a description of the problems).
|
||||||
|
It has a built-in table of known VESA modes, as well as all non-VESA
|
||||||
|
modes that the mach64 BIOS supports, but currently the non-VESA mode
|
||||||
|
setting doesn't work properly, so only VESA modes are enabled. However,
|
||||||
|
it is able to take advantage of extra VESA modes provided by tools like
|
||||||
|
Scitech Display Doctor.
|
||||||
|
|
||||||
|
It supports 8, 15, 16, 24, and 32 bits per pixel, if available. It
|
||||||
|
currently provides acceleration for these primitives:
|
||||||
|
|
||||||
|
DrawScan()
|
||||||
|
DrawPattScan()
|
||||||
|
DrawRect()
|
||||||
|
DrawPattRect()
|
||||||
|
BitBlt()
|
||||||
|
SrcTransBlt() (not in 24bpp)
|
||||||
|
DrawLine() (not in 24bpp)
|
||||||
|
|
||||||
|
These accelerated functions are planned and may be provided in the
|
||||||
|
future:
|
||||||
|
|
||||||
|
DrawTrap() (actually the mach64 seems to be able to draw entire
|
||||||
|
polygons, too bad there isn't a DrawPoly() in VBE/AF;
|
||||||
|
DrawTri() and DrawQuad() may be possible, but since
|
||||||
|
they are not widely used, who cares about them)
|
||||||
|
PutMonoImage() (using HOST transfer, perhaps)
|
||||||
|
BitBltSys() (using HOST transfer)
|
||||||
|
SrcTransBltSys() (same here)
|
||||||
|
SetCursor()
|
||||||
|
SetCursorPos()
|
||||||
|
SetCursorColor()
|
||||||
|
ShowCursor()
|
||||||
|
|
||||||
|
This driver is not portable to anything but DOS+DPMI, since it uses
|
||||||
|
DPMI to communicate with the mach64 BIOS.
|
||||||
|
|
||||||
|
Both linear and banked modes are supported, but SetBank32 is in the
|
||||||
|
current (sloppy) implementation not fully relocatable, but this should
|
||||||
|
rarely be a problem since linear modes are much more fun anyway.
|
||||||
|
|
||||||
|
If you want to have 32bpp and 1600x1200 modes without having to
|
||||||
|
install Scitech Display Doctor, define REFUSE_VESA and try to find out
|
||||||
|
why the mach64 mode settings doesn't work properly, then uncomment the
|
||||||
|
appropriate extra modes, and report to me.
|
||||||
|
|
||||||
|
Virtual heights above screen height (for hardware scrolling) may not
|
||||||
|
work properly above 8bpp, I'm not sure why yet, but it looks like it
|
||||||
|
could be a bug in Allegro.
|
||||||
|
|
||||||
|
DrawLine does not seem to be rounded exactly like Allegro's, which
|
||||||
|
becomes evident when clipping.
|
||||||
|
|
||||||
|
I'm not sure how to do patterns. It is possible to load an 8x8 mono
|
||||||
|
pattern into the mach64 registers and use it, but I'm not sure how,
|
||||||
|
but I made a guess and implemented that, and it seems to work, but
|
||||||
|
I'm not totally sure. As for color patterns, I have just disabled
|
||||||
|
them since I haven't figured out how to do those yet. It would be
|
||||||
|
possible to use Shawn's technique; to bitblt them from offscreen VRAM,
|
||||||
|
but use TILE_X enabled for automatic tiling, but it doesn't seem
|
||||||
|
worthwhile at present, if there is a better way.

Matrox driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This driver supports the Millenium, Mystique, and Millenium II (both PCI
|
||||||
|
and AGP) cards.
|
||||||
|
|
||||||
|
It supports color depths of 8, 15, 16, and 32 bits per pixel in both
|
||||||
|
linear and banked modes, and should be able to use all the resolutions
|
||||||
|
provided by your underlying VESA driver. It provides accelerated versions
|
||||||
|
of the VBE/AF functions:
|
||||||
|
|
||||||
|
DrawScan()
|
||||||
|
DrawPattScan()
|
||||||
|
DrawColorPattScan()
|
||||||
|
DrawRect()
|
||||||
|
DrawPattRect()
|
||||||
|
DrawColorPattRect()
|
||||||
|
DrawLine()
|
||||||
|
DrawTrap()
|
||||||
|
PutMonoImage()
|
||||||
|
BitBlt()
|
||||||
|
BitBltSys()
|
||||||
|
SrcTransBlt() - Mystique only
|
||||||
|
SrcTransBltSys() - Mystique only
|
||||||
|
|
||||||
|
This driver supports the FreeBE/AF extension mechanism for enabling true
|
||||||
|
protected mode access to video memory. Uncomment the definition of
|
||||||
|
NO_HWPTR at the top of driver.c if you want to return to the standard
|
||||||
|
nearptr memory access.
|
||||||
|
|
||||||
|
Masked blitting from system memory is only enabled in 256 color modes,
|
||||||
|
because in truecolor resolutions it is actually faster to do the masking
|
||||||
|
checks in software (the increased pixel size means that too much time is
|
||||||
|
wasted copying zeros to the card, so it is more efficient for the cpu to
|
||||||
|
test and discard these).
|
||||||
|
|
||||||
|
Hardware cursors are supported, but only on the Mystique. The Millenium
|
||||||
|
does them quite differently, and I have no way to test any code for it.
|
||||||
|
|
||||||
|
This code is not portable to any platforms other than DOS+DPMI, because
|
||||||
|
it uses VESA calls to set the initial video mode.

NVidia driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This driver should in theory support both the NVidia Riva 128 and Riva
|
||||||
|
TNT cards, but it has only been tested on the TNT. I'd be very interested
|
||||||
|
to hear whether it works on the 128 or not, although I'm afraid there
|
||||||
|
isn't much I can do to fix any problems on hardware that I don't own.
|
||||||
|
|
||||||
|
This driver doesn't work properly under Windows. It will run ok, but
|
||||||
|
after using it, you can't switch back to your Windows desktop. I have no
|
||||||
|
idea why this is.
|
||||||
|
|
||||||
|
It supports color depths of 8, 16, and 32 bits per pixel in both linear
|
||||||
|
and banked modes, and resolutions of 320x200, 320x240, 320x400, 640x400,
|
||||||
|
640x480, 800x600, 1024x768, and 1280x1024 (this last not in 32 bit mode).
|
||||||
|
Other modes can easily be added if you know the register values for them.
|
||||||
|
|
||||||
|
It provides accelerated versions of the VBE/AF functions:
|
||||||
|
|
||||||
|
DrawScan()
|
||||||
|
DrawRect()
|
||||||
|
DrawTrap()
|
||||||
|
PutMonoImage()
|
||||||
|
BitBlt()
|
||||||
|
SetCursor()
|
||||||
|
SetCursorPos()
|
||||||
|
SetCursorColor()
|
||||||
|
ShowCursor()
|
||||||
|
|
||||||
|
Patterned drawing is not accelerated. I have some routines that sort-of
|
||||||
|
worked for this, but couldn't get them to do the right thing in all the
|
||||||
|
possible drawing modes. Since I got that code from an alpha version of an
|
||||||
|
XFree86 driver which itself doesn't do patterned modes properly, this is
|
||||||
|
not exactly surprising. I'll add that acceleration as soon as I get some
|
||||||
|
decent info about how it works.
|
||||||
|
|
||||||
|
This driver is unable to use more than 16 meg of video memory, because
|
||||||
|
I'm unable to detect the amount of vram until after I map the
|
||||||
|
framebuffer, at which point it is too late to request a larger memory
|
||||||
|
block.
|
||||||
|
|
||||||
|
The hardware scrolling and bank switching code may not be entirely
|
||||||
|
correct, because I didn't have any docs for how the bank switch system
|
||||||
|
works, and the scrolling routine supplied in XFree86 is broken. The code
|
||||||
|
in this driver works correctly on my TNT, but your mileage may vary.
|
||||||
|
|
||||||
|
This driver does not implement the FreeBE/AF farptr extension mechanism,
|
||||||
|
which means that it only works with nearptrs enabled. This could be
|
||||||
|
altered if enough people feel strongly about it, but would be a
|
||||||
|
considerable pain because I'd have to rewrite most of the NVidia helper
|
||||||
|
routines as well as my own driver code.
|
||||||
|
|
||||||
|
This code is heavily based on the NVidia driver from XFree86 version
|
||||||
|
3.3.3.1. In particular, the source file riva_hw.c was copied directly
|
||||||
|
from XFree86. This imposes two restrictions on me. First, I have to say
|
||||||
|
that NVidia is an exceptionally cool company, and they deserve much
|
||||||
|
congratulation for releasing this nice bit of reusable driver source.
|
||||||
|
Also, to comply with their BSD-style licensing terms, I have to reproduce
|
||||||
|

Paradise driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This is a software-only driver for Paradise chipsets, based on the native
|
||||||
|
Paradise driver from old versions of the Allegro library. It only
|
||||||
|
supports 256 color modes, and has no support for linear framebuffers or
|
||||||
|
accelerated drawing. As such it is useful primarily because it is faster
|
||||||
|
than the VESA 1.x bank switching mechanism, and as a workaround for the
|
||||||
|
many bugs in common VESA driver implementations.
|
||||||
|
|
||||||
|
This code is not portable to any platforms other than DOS+DPMI, because
|
||||||
|
it uses BIOS calls to set the initial video mode.
|
||||||
|
|
||||||
|
Any volunteers to add hardware accelerator support? That would be very
|
||||||
|
welcome if you want to do it :-)

S3 driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This is a driver for S3 chipsets. It supports 8/15/16/24/32bits color
|
||||||
|
modes, and has support for accelerated drawing (currently only for BitBlt
|
||||||
|
between vram).
|
||||||
|
|
||||||
|
This code is not portable to any platforms other than DOS+DPMI, because
|
||||||
|
it uses BIOS calls to set the initial video mode.
|
||||||
|
|
||||||
|
|
||||||
|
Accelerated functions
|
||||||
|
---------------------
|
||||||
|
|
||||||
|
BitBlt - I'm sorry I didn't add more functions yet, but I haven't got a
|
||||||
|
time and this function was very important for me. I hope it help
|
||||||
|
you too. If I had a more time a I will send to Allegro new
|
||||||
|
functions.
|
||||||
|
|
||||||
|
|
||||||
|
Supported Hardware
|
||||||
|
------------------
|
||||||
|
|
||||||
|
I think all earlier S3 cards and some older. I'm sure for Trio64, I
|
||||||
|
tested it. If somebody have a problem, please send me note and your
|
||||||
|
ident. number of S3 card.
|
||||||
|
|
||||||
|
Thank you, Michal Stencl

Stub driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This is an example driver implementation, intended as a starting point
|
||||||
|
for anyone who wants to make a real driver for a specific card. It
|
||||||
|
provides all the essential VBE/AF functions, but it runs on top of your
|
||||||
|
existing VESA driver, using VESA calls to set the video mode and then
|
||||||
|
simple software drawing functions to emulate the hardware accelerated
|
||||||
|
operations. As such it is not useful in any practical way, but it does
|
||||||
|
work: just copy the vbeaf.drv file to c:\ and you should be able to use
|
||||||
|
it from any Allegro programs, or the SciTech VBETEST utility (run
|
||||||
|
"vbetest -f" to use VBE/AF rather than regular VESA).
|
||||||
|
|
||||||
|
This driver is not portable, because it uses DPMI calls to communicate
|
||||||
|
with VESA. This is no problem as long as it is being used with Allegro,
|
||||||
|
but the binary will not work on any other platforms until you have
|
||||||
|
removed all the VESA calls and are using direct hardware access for
|
||||||
|
everything.
|
||||||
|
|
||||||
|
This driver provides "accelerated" (emulated in software, and painfully
|
||||||
|
slow, but they look like hardware functions to the calling program),
|
||||||
|
versions of the VBE/AF routines:
|
||||||
|
|
||||||
|
WaitTillIdle()
|
||||||
|
SetMix()
|
||||||
|
Set8x8MonoPattern()
|
||||||
|
Set8x8ColorPattern()
|
||||||
|
Use8x8ColorPattern()
|
||||||
|
DrawScan()
|
||||||
|
DrawPattScan()
|
||||||
|
DrawColorPattScan()
|
||||||
|
DrawRect()
|
||||||
|
DrawPattRect()
|
||||||
|
DrawColorPattRect()
|
||||||
|
DrawLine()
|
||||||
|
DrawTrap()
|
||||||
|
PutMonoImage()
|
||||||
|
BitBlt()
|
||||||
|
BitBltSys()
|
||||||
|
SrcTransBlt()
|
||||||
|
SrcTransBltSys()
|
||||||
|
|
||||||
|
If you don't want to support all these in your driver, they should be
|
||||||
|
replaced with NULL pointers so the caller will know to use their normal
|
||||||
|
drawing code instead. VBE/AF provides many more routines than these, but
|
||||||
|
Allegro only uses the ones from that list, so it would be rather futile
|
||||||
|
to implement any others.
|
||||||
|
|
||||||
|
This driver supports the FreeBE/AF extension mechanism for enabling true
|
||||||
|
protected mode access to video memory. Uncomment the definition of
|
||||||
|
NO_HWPTR at the top of driver.c if you want to return to the standard
|
||||||
|
nearptr memory access.
|
||||||
|
|
||||||
|
If you comment out the definition of USE_ACCEL at the top of driver.c,
|
||||||
|
the emulated acceleration routines will be removed, leaving only a dumb
|
||||||
|
framebuffer driver. This may be useful to see what is the bare minimum of
|
||||||
|
functions that you need to include in a VBE/AF driver.
|
||||||
|
|
||||||
|
This driver implements the FreeBE/AF FAF_CFG_FEATURES extension
|
||||||
|
mechanism, which allows the installation program to selectively disable
|
||||||
|
some of the hardware accelerated drawing routines. Comment out the
|
||||||
|
definition of USE_FEATURES at the top of driver.c if you want to remove
|
||||||
|
this capability.
|
||||||
|
|
||||||
|
There is no support for hardware cursors, 8 bit DAC modes, or the refresh
|
||||||
|
rate control functions.
|
||||||
|
|
||||||
|
The VESA implementation assumes a single 64k memory bank, so it will not
|
||||||
|
function correctly on cards with dual banks or other granularities. This
|
||||||
|
won't be a problem for the real drivers, though, because you will know
|
||||||
|
the granularity in advance. VBE/AF only allows 4k or 64k, so other sizes
|
||||||
|
must be scaled up to 64k units.

Trident TGUI9440AGi driver implementation notes.
|
||||||
|
|
||||||
|
Warning: My english is bad ;-)
|
||||||
|
|
||||||
|
|
||||||
|
This is the FreeBE/AF implementation for the Trident 9440 chipset for
|
||||||
|
PCI boards.
|
||||||
|
The driver is quite complet but there are some limitations:
|
||||||
|
|
||||||
|
1) The driver doesn't work under Windows.
|
||||||
|
2) The driver doesn't work with SciTech tools like vbetest.exe.
|
||||||
|
3) The hardware cursor isn't 100% compliant.
|
||||||
|
|
||||||
|
Here are explanations about each topic:
|
||||||
|
|
||||||
|
1) Trident drivers for Windows aren't good wenough to support a DOS
|
||||||
|
application setting the mode at register level. The drivers can emulate
|
||||||
|
VBE calls successfully but virtualize some critical registers avoiding
|
||||||
|
changes to this registers.
|
||||||
|
I think that isn't an important limitation because the main goal of
|
||||||
|
this driver is enhance the performance of DOS Allegro programs and they
|
||||||
|
works much better under pure DOS.
|
||||||
|
|
||||||
|
2) I realised it too late, but this time SciTech taked the desition to
|
||||||
|
close the Nucleus standard (the VBE/AF sucesor). So I'll address this
|
||||||
|
topic only if somebody really needs support for it.
|
||||||
|
|
||||||
|
3) In the future I'll add a way to disable the hardware cursor
|
||||||
|
acceleration, but by now I think is better to let it on all the time.
|
||||||
|
|
||||||
|
The implemented routines are the following:
|
||||||
|
|
||||||
|
WaitTillIdle()
|
||||||
|
SetMix()
|
||||||
|
Set8x8MonoPattern()
|
||||||
|
Set8x8ColorPattern()
|
||||||
|
Use8x8ColorPattern()
|
||||||
|
DrawScan()
|
||||||
|
DrawScanList()
|
||||||
|
DrawPattScan()
|
||||||
|
DrawPattScanList()
|
||||||
|
DrawColorPattScan()
|
||||||
|
DrawColorPattScanList()
|
||||||
|
DrawRect()
|
||||||
|
DrawPattRect()
|
||||||
|
DrawColorPattRect()
|
||||||
|
DrawLine()
|
||||||
|
DrawTrap() *4
|
||||||
|
SetLineStipple() *1
|
||||||
|
SetLineStippleCount() *1
|
||||||
|
DrawStippleLine() *1
|
||||||
|
PutMonoImage()
|
||||||
|
BitBlt()
|
||||||
|
BitBltSys()
|
||||||
|
SrcTransBlt()
|
||||||
|
SrcTransBltSys()
|
||||||
|
GetVideoModeInfo()
|
||||||
|
SetVideoMode() *3
|
||||||
|
RestoreTextMode()
|
||||||
|
SetDisplayStart()
|
||||||
|
SetActiveBuffer()
|
||||||
|
SetVisibleBuffer()
|
||||||
|
GetDisplayStartStatus() *5
|
||||||
|
SetBank()
|
||||||
|
SetPaletteData()
|
||||||
|
SetCursor()
|
||||||
|
SetCursorPos()
|
||||||
|
SetCursorColor() *2
|
||||||
|
ShowCursor()
|
||||||
|
GetClosestPixelClock()
|
||||||
|
|
||||||
|
Notes:
|
||||||
|
*1 I'm not sure about the implementation but the functions have
|
||||||
|
equivalent registers in the chip.
|
||||||
|
*2 9440 doesn't support it, that's a wrapper.
|
||||||
|
*3 Supports the AF_CRTCInfo parameter!
|
||||||
|
*4 Implemented using scans because isn't supported by the hard.
|
||||||
|
*5 Dummy because looks like TGUI doesn't set the interrupt flag.
|
||||||
|
|
||||||
|
Additionally I did some attempts to implement the following Inertia
|
||||||
|
functions, but they are disabled because SciTech dropped it:
|
||||||
|
|
||||||
|
GetConfigInfo
|
||||||
|
GetCurrentMode
|
||||||
|
SetVSyncWidth
|
||||||
|
GetVSyncWidth
|
||||||
|
GetBank
|
||||||
|
GetVisibleBuffer
|
||||||
|
GetDisplayStart
|
||||||
|
SetDisplayStartAddr
|
||||||
|
IsVSync
|
||||||
|
WaitVSync
|
||||||
|
GetActiveBuffer
|
||||||
|
IsIdle
|
||||||
|
|
||||||
|
The driver was implemented without using BIOS calls for this reason is
|
||||||
|
much more complex than current FreeBE/AF drivers (october 1998).
|
||||||
|
TGUI9440 doesn't support acelerations in 24 bpp, the modes are supported
|
||||||
|
but without accelerations.
|
||||||
|
|
||||||
|
Supported video modes:
|
||||||
|
|
||||||
|
8 bpp 15 bpp 16 bpp 24 bpp
|
||||||
|
320x200 * * * *
|
||||||
|
320x240 * * * *
|
||||||
|
400x300 * * * *
|
||||||
|
512x384 * * * *
|
||||||
|
576x432 * * * *
|
||||||
|
640x400 * * * *
|
||||||
|
640x480 * * * *
|
||||||
|
720x540 * * * *
|
||||||
|
800x600 * * * *
|
||||||
|
900x675 * * * *
|
||||||
|
1024x768 * * * (1)
|
||||||
|
|
||||||
|
(1) Needs more than 2Mb so is impossible with 9440
|
||||||
|
|
||||||
|
Other modes could be implemented using AF_CRTCInfo and
|
||||||
|
GetClosestPixelClock, that's a good feature of VBE/AF.
|
||||||
|
|
||||||
|
|
||||||
|
Technical notes:
|
||||||
|
* I'm bliting to the 0xA0000 region instead of the LFB in BitBltSys
|
||||||
|
because that's faster in the Ivan's motherboard, don't ask me why.
|
||||||
|
* See the sources for more information.
|
||||||
|
* Addtionally you can take a look to the vbeaf.htm included, it was
|
||||||
|
generated by my editor with almost no extra efforts.
|
||||||
|
|
||||||
|
|
||||||
|
Thanks to:
|
||||||
|
* The rest of the FreeBE/AF team, specially Shawn, the stub helped a lot
|
||||||
|
and I took ideas from various drivers.
|
||||||
|
* The people at Trident, they sent me the printed manuals of the board
|
||||||
|
without asking a cent (they invested money on it!)
|
||||||
|
* Kendall Benett, even when SciTech taked the desition to close the
|
||||||
|
Nucleus spec Kendall was very kind answering some questions about
|
||||||
|
functions, specially about the AF_CRTCInfo structure.
|
||||||
|
* Ivan Baldo, my beta tester.
|
||||||
|
|
||||||
|
|
||||||
|
Legal notes:
|
||||||
|
* All trademarks are property of their owners ;-))), I don't know why
|
||||||
|
manuals point out it, sounds funny no?
|
||||||
|
* The fonts included where dumped from the Trident's BIOS, I guess that's
|
||||||
|
OK because the driver works only with Trident boards ;-).
|
||||||
|
* Here goes another silly one: The information presented in this
|
||||||
|
publication has been carefully tested for reliability; however, no
|
||||||
|
responsability is assumed for inaccuracies. Specifications are subject
|
||||||
|
to change without notice. =-))))))))))
|
||||||
|
* Now seriously: this driver is under the FreeBE/AF license and no
|
||||||
|
warranty is provided (after all: try to sue M$ for the time lost
|
||||||
|
reinstalling Windows over and over each time it screws your HD ;-).

Trident driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This is a software-only driver for Trident chipsets, based on the native
|
||||||
|
Trident driver from old versions of the Allegro library. It only supports
|
||||||
|
256 color modes, and has no support for linear framebuffers or
|
||||||
|
accelerated drawing. This code has been made obsolete by the accelerated
|
||||||
|
TGUI driver recently written by SET, and is included only because it may
|
||||||
|
support a slightly wider range of chipset variants. Any future
|
||||||
|
development effort should be spent on improving the TGUI driver instead
|
||||||
|
of this one.
|
||||||
|
|
||||||
|
This code is not portable to any platforms other than DOS+DPMI, because
|
||||||
|
it uses BIOS calls to set the initial video mode.

Tseng driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This is a software-only driver for the Tseng ET3000, ET4000, and ET6000
|
||||||
|
chipsets, based on the native Tseng drivers from old versions of the
|
||||||
|
Allegro library. It has no support for linear framebuffers or accelerated
|
||||||
|
drawing operations. As such it is useful primarily because it is faster
|
||||||
|
than the VESA 1.x bank switching mechanism, and as a workaround for the
|
||||||
|
many bugs in common VESA driver implementations.
|
||||||
|
|
||||||
|
This code is not portable to any platforms other than DOS+DPMI, because
|
||||||
|
it uses BIOS calls to set the initial video mode.
|
||||||
|
|
||||||
|
Any volunteers to add hardware accelerator support? That would be very
|
||||||
|
welcome if you want to do it :-)

Video-7 driver implementation notes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
This is a software-only driver for Video-7 chipsets, based on the native
|
||||||
|
Video-7 driver from old versions of the Allegro library. It only supports
|
||||||
|
256 color modes, and has no support for linear framebuffers or
|
||||||
|
accelerated drawing. As such it is useful primarily because it is faster
|
||||||
|
than the VESA 1.x bank switching mechanism, and as a workaround for the
|
||||||
|
many bugs in common VESA driver implementations.
|
||||||
|
|
||||||
|
This code is not portable to any platforms other than DOS+DPMI, because
|
||||||
|
it uses BIOS calls to set the initial video mode.
|
||||||
|
|
||||||
|
Any volunteers to add hardware accelerator support? That would be very
|
||||||
|
welcome if you want to do it :-)
