[Dri-users] DRM problems with G400 in 9-28-2000 CVS

[Ravi K. S. <rk...@rt...>]

I downloaded the latest tree through CVS last night (9-28-2000) and can't
get 3D to work anymore.  Brief history, I was using Redhat 6.2 
with XFree86 3.3.6 and Utah-GLX and got ~40fps in Quake3.  I'm trying out
Redhat 7.0 w/ XFree86 4.0.1 and now I only get ~29fps.  I've seen other
posters say that moving from Utah-GLX to DRI gave about a 5% speedup but
I wasn't expecting a 25% slowdown.  I downloaded the latest CVS tree
and it looks like the mga.o module is 2.0.0 (20000910) while RH 7.0 shipped
version 1.0.0 but now I get DRM errors when starting the server.

Any ideas?

With the new CVS tree the drm fails to initialize correctly:

(==) MGA(0): Write-combining range (0xd8000000,0x1000000)
(--) MGA(0): 16 DWORD fifo
(==) MGA(0): Default visual is TrueColor
(II) MGA(0): [drm] bpp: 16 depth: 16
(II) MGA(0): [drm] Sarea 2176+632: 2808
(0): [drm] drmSetBusid failed (6, PCI:1:0:0)

Before it would initialize correctly like below:

(==) MGA(0): Write-combining range (0xd8000000,0x1000000)
(--) MGA(0): 16 DWORD fifo
(==) MGA(0): Default visual is TrueColor
(II) MGA(0): [drm] Sarea 2176+624: 2800
(0): [drm] created "mga" driver at busid "PCI:1:0:0"
