Summary: r300_check_offset fails on PCI-E R420 (5D4F)
Product: DRI
Version: DRI CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DRM modules
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
I'm using an AMD64 computer with X800 GTO PCI-Express gfx card (5D4F). I'm using
both a) Ubuntu 6.06 LTS default configuration and b) Ubuntu edgy development
branch with kernel 2.6.17 drm modules, mesa 6.5.0.cvs.20060725,
xserver-xorg-driver-ati-6.6.1 and libdrm cvs. Glxinfo gives me "Direct
rendering: Yes", but glxgears gives: drmRadeonCmdBuffer: -22 (exiting)
In both configurations, dmesg shows the following after trying to run glxgears:
[ 1849.338955] [drm:r300_emit_carefully_checked_packet0] *ERROR* Offset failed
range check (reg=4e28 sz=1)
[ 1849.338960] [drm:r300_do_cp_cmdbuf] *ERROR* r300_emit_packet0 failed
For some reason, r300_check_offset in r300_cmdbuf.c is failing while it probably
should not. At least if I force that function to return 0; (in the Ubuntu edgy
configuration), glxgears runs without problems (ca. 2800 fps) and so does a
couple of screensavers.
Any idea what's going wrong? If you need more information, just tell what should
I find out.
