[parisc-linux] Voodoo 2

[M. Grabert]

Hi,

I'm about to purchase a Voodoo2 PCI graphics card since I saw some
reports on the p-l list that it is working on Linux/PA-RISC.


I want to ask a couple of questions before I'm going to buy the graphics card:

- Helge prepared a patch to make the Voodoo working, and was incorporated
  into the 2.4.19-pa18 kernel. It seems that it's still in 2.4.25-pa1.
  But is the patch integrated into the mainstream 2.4?
  I just took a brief look, and it appears so, is this correct?


- What about 2.6? I don't think that it's been forwarded to 2.6 yet?


- there is also the XFree86 Voodoo 1/2 driver from Alan Cox
(http://lists.parisc-linux.org/pipermail/parisc-linux/2004-February/022382.html)

  I suppose this driver also doesn't require the Voodoo2 card to be initialized,
  and I think the advanage over using sstfb would be that it supports DGA
  and some 2D acceleration.

  Has anybody tested it (I couldn't even compile it)?


Thanks alot,
  Max

hmm... if they are useful to people. anybody (us sf bay area local)
wants one of these (or a singleboard v2 sli) they can have them (you
can't have my cool fib-ed board #2, since it probably won't work anymore
:-)

anyway, i'm not sure what you meant by 'initialization', but the init
code can be done at anytime and doesn't need to have any special
boot-time interpreter stuff (unlike

Mostly the 2D acceleration is useful

You need to drop it into a full XFree 4.3/X.org 6.7 tree to build
which makes it umm fun. When you get to that point I can give you
instructions and we can debug it 8)

No idea yet. I will check.

It's in 2.6. I just tested my Vodoo2 in my c3k and it works.
Linux version 2.6.5-pa6 (root@p100) (gcc version 3.0.2 20010829 (prerelease)) #29 Mon Apr 12 22:46:03 CEST 2004
The 32-bit Kernel has started...
..
sstfb: Voodoo2 (revision 2) with ICS ICS5342 dac
sstfb: framebuffer at 0xfb400000, mapped to 0xfb400000, size 2MB
fb0: Voodoo2 frame buffer device at 0xfb400000
..

I can run the driver, graphics & Tux penguin comes up.
Running "fbset -a 1024x768-75" even gives me a nice big screen (although
I still don't like this "stty cols 64 rows 48" stuff yet...)

At least it should (if it works :-))

Neither me (I was lacking the XFree86 sources).

this interests me since i'd love to get something better than the 8bit vid 
card running in my C360 :)

i threw my obsidian voodoo2 into my box, but it did what it always has for 
me ... i build the sstfb as a module and when i modprobe it, the box locks 
up ... i builld it as a module because otherwise it'll lock at boot and i 
have to do a little manual rescue foo :)

My above test was with the sstfb driver built-in into the kernel and with all
other graphics drivers (incl. stifb and STI text console) disabled.

FYI, this is what my graphics-relevant part of .config looked like:
#

Then, in a second test I enabled STIFB, and choosed SSTFB as module.
Booting up worked:

Works too...

ok, here's what i found ...

the card i originally tried doesnt seem to work atm ... it's the obsidian card 
that was top of the line in its day because it's basically 2 voodoo2's on 1 
pci card ... when i modprobe the module, machine locks up ... when i boot 
with the driver built in, it dies, but i can at least see a bunch of oops 
messages ;)

i had another voodoo2 card, a sti black magic, and it works as you 
advertise :)

thanks
