Summary: X.org 6.8.2 does not activate DRI on i865 but says it
does
Product: DRI
Version: XOrg CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DRM modules
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
Hi,
I am trying to use X.org 6.8.2 on my Debian Sarge.
My machine is a Dell Dimension 3000 with an Intel 865G Graphics Chipset.
0000:00:02.0 VGA compatible controller: Intel Corp. 82865G Integrated Graphics
Device (rev 02)
XFree 4.3.0 from Sarge works almost well but the i810 driver still has some bugs
so I tried X.org 6.8.2 (compiled by myself).
Xorg.log and glxinfo say DRI is enabled.
But every 3D programs I tried (especially crack-attack and quake3) are obviously
way slower than under XFree 4.3.0.
It looks to me that they are as slow as when DRI is disabled.
glxgears reports 500fps with XFree/DRI and 800 with XFree without DRI
(my processor is faster than my GPU ???)
glxgears under Xorg reports 800 too. That's why it looks like without DRI.
dmesg looks good except this:
mtrr: base(0xe8020000) is not aligned on a size(0x960000) boundary
.config, lspci, dmesg, xorg.conf and Xorg.0.log attached
Note that this Dell machine has a buggy BIOS which does not report Video RAM
well. I tried the i865 patch to fix it, but this didn't change anything.
This leads to Xorg.0.log containing things like:
(WW) I810(0): Detected stolen memory (8000 kB) doesn't match what the BIOS
reports (130880 kB)
(II) I810(0): I830CheckAvailableMemory: 441340 kB available
(--) I810(0): Pre-allocated VideoRAM: 8060 kByte
(==) I810(0): VideoRAM: 32768 kByte
