it isn't a case of turning up noses at games or gaming hardware;
it's often a matter of manufacturers not
releasing the data required to program them, or not without one or more of:
a fuss, NDA, no source distribution, internet lobbying, manufacturer
jumping on linux bandwagon, and reverse engineering.
it's a lot of fuss for a research group once they've got drivers for
a reasonable selection of reasonable cards from reasonable manufacturers,
updated periodically as cards come and go.

That is all very true and I somehow don't think P9 is envisioned as a gaming
platform anytime in the near future;however,I hardly think,going by the
hardware computability list,' reasonable' comes to mind when looking at the
supported cards.

By all means develop drivers for other cards that interest you,
and contribute them to the cause.  If they work at all I suspect
they'll be added to the distribution.

Well, it looks like maybe they started by bringing the antique 2nd Edition
(1995) drivers forward, to get 3rd Edition off the ground.  And 3rd Edition
has only been out a few months.  Maybe this situation will improve.

These days, though, every graphics card for the PC is a 3D gaming card, and
right now Matrox is the only company doing the right thing with documentation.
You can look at XFree86, but XFree86 has a lot of problems with a lot of
cards; bugs are rife, and many drivers aren't even accelerated.  So it's a
pretty grim situation.

For this plan to work, people must have the system installed

that might be difficult.

3D visualization is one of the areas where distributed computing
still fills a real need.  So a 3D card in a PC isn't necessarily
just for games, with a system like Plan 9.

Assuming you have (or can get) one.  Most of them are obsolete.

Then there's the issue of either setting up a spare machine,

We're using the Diamond Stealth 3d 2000 vers 1.04 here.  While
obsolete, there are workarounds.  You can actually get a DS3D2K with other
bios versions (higher than 1.04), pull the chip off, and stick in a 1.04
you've burned yourself and it works great (e-me for board revs we've
tested this with).  I think I found one of these cards on ebay a few
months back for around $12.

I'll pass along the MOT S19 records for the 1.04 bios if anyone would
like them.

Well, the stated reason is wrong.  There is a "reasonableness
clause" in the law, such that the remedy _cannot_ be unreasonably
onerous.

Requiring anyone who writes software to port and support on all
possible platforms would clearly be unreasonably onerous.

Chip companies, however, already have register-level documentation
for their own internal use, so making it public is not itself
onerous at all, especially with the Internet.  And support should
not be required, beyond keeping the documentation reasonably up
to date.

In other words, the circumstances are simply not comparable.  OS
writers shouldn't have to port to all hardware, and application
writers shouldn't have to port to all OSes.  However, OS companies
should have to provide reasonable documentation to all application
writers, and hardware complanies should have to provide reasonable
documentation to all OS writers.

Chuck Moore, author of Forth, designs CPUs in his kitchen. Not FPGAs,
fast small silicon. It takes some funding to get a fab run, but if you
have a chip, funding shouldn't be too too tough. Chuck's stuff is
weird, but it screams. So the means to make it exist. How big is another
matter. I like to think Microsoft, for example, is an unfortunate
(for the rest of us) fluke.

Surely that's not essential?  I'm thinking (but please keep in mind I'm
very much a graphics layman) of something like Tk's widgets and the means
to manipulate them as an extreme case.  3D, naturally, would require
extensions, but a language like Tcl, even if not necessarily to
everyone's tastes, would enable the construction of such extensions.  Of
course, one still needs the channel for the communication of commands and
responses between the graphic engine and the client, but is the above
idea really totally off the mark?

Sorry, poor wording.  It migrated from the bus or the serial port, I
didn't mean to imply that it ever was on the display adapter.  I remember
Intel making some combination blit/mouse/network adapters in the late 80s
and early 90s, but they weren't terribly popular.  Then again, screen
capabilities in those days weren't exactly at the commodity level, and I
may be misremembering about the mouse as well.

My point is that graphics have more or less always been accompanied by
the mouse in the history of commodity computing.

Actually, I wasn't laying blame, I was just alluding

There's a small matter of U.S. anti-trust law, and a
principle known as "fair access to essential
facilities".  It dates back to the railroad tycoons,
fer cryin' out loud.  Ironically, the case has been
made against Microsoft software.  It's even more
obvious with respect to chips, but as far as I know
(not very far) no one has tried making the case.

In this context "fair access" means public
documentation, sufficient for any competent graphics
chip driver writer to write his own "naked hardware"
driver -- for any arbitrary OS -- which uses all
features of the chip claimed by the chip's maker.

In other words, legally you shouldn't _need_ to burn
your own silicon, at least not in the U.S.

A "sensible protocol" would be a flat frame buffer with
a single color depth.  Unfortunately, the vast majority of
today's customers for add-in video cards want the fastest,
most featureful 3D rendering engines.  Presumably many of
the details of the 2D interface are dictated by the needs
of the 3D design, including the bus cache.  Of course, the
"standard" VGA/SVGA modes that evolved step by step from
the original IBM VGA over the years must still be supported
for such things as Windows "Safe Mode".

The mouse was never (on the PC platform) closely coupled
with the display.  Typical PCs do not "need" a mouse, but
it is more tedious to navigate in Windows via the keyboard.

It still baffles me why nobody has produced a graphic card that
speaks a sensible protocol instead of being variously I/O and memory
mapped in the most unorthodox manners.

For that matter, why on earth did the mouse controller migrate to
the keyboard handler, when I have yet to see a single PC clone with
a video card that did not need a mouse?

The Ontel Amigo (1979 vintage?) had dual ported memory (all of
32KB) into which the 8085 (or Z80?) would deposit a 6502 program
to drive the graphics output.  The default program was provided as
source, so you could do whatever you liked with it.

Am I being naive, or is it too late for that type of sensible
engineering to happen again?  Have Intel really disbanded the i860
team?

The other question, unfortunately, is whether there is any room
for the double Steves of the world, I mean, garage engineering

Well, there's no response to that level of fanaticism.

But there really is a serious problem with chip companies
claiming their register sets are somehow proprietary.

If the Wall Street crowd had their way, Microsoft would
declare their drop-down menus proprietary, so you'd have
to hire someone to operate your PCs for you.

In general, the more 3D oriented, and state-of-the-art,
the less likely the card is to be supported. This is partially
a function of the proprietary nature of 'gamers' cards,
and partially the unlikelihood that researchers in Plan 9
have found the need to support such cards.

If you read the hardware compatibility specs, you will
see what is supported in the current release. The usual
line is 'ATi mach64 based cards are OK'. Of course, if
you see it mentioned in /lib/vgadb then this is encouraging.

Support is improving, though. If you check the archives,
you will see that a Voodoo 3 and S3 Savage drivers have been
done, but not yet released. Matrox G200/G400 may not be far away.

On the flip side, no Ati 128 bit cards are supported.

Another important rule of thumb is 'does XFree86 support
it'. This is an indication as to whether the technical
documentation needed to write a driver is available.
At one time certainly, Nvidia were difficult.
