I finally have access to an x86 SMP box, and I have a few cycles to look
at the SMP related problems. I'm using an AGP G400 and quake3-smp. Like
Dieter, I get a black screen and a hung program. When I break in with
GDB, here is the stack trace. Dieter, does this match what you see?
That problem appears to have been a simple deadlock. The LockDisplay /
UnlockDisplay calls were not balanced in various paths through
MakeContextCurrent. The attached patch fixes that problem. I still hit
other problems on MGA, but they *appear* to be MGA specific.
Dieter: Could you try this patch on R200 and let me know if it helps.
I'll keep working on the other issues.
After applling your patch I can run Q3A in window mode at 640x480x32 (on a
1280x1024x32 desktop) with most on and _sound_ as fast as _without_ sound
before ;-)
dual Athlon MP 1900+
MSI K7D Master-L (AMD 768 MPX)
1 GB DDR266, CL (2x 512 MB)
Radeon 8500QL
S3TC is in for sure;-)
640x480x32
166-167,6 with and without sound
Without SMP I get:
136 with sound
166 without sound
The r200 is the clear bottleneck, now
What we need next is the TMU3 patch...;-)
Cheers,
Dieter
