Message-ID: <20031105194942.51568.qmail@web40908.mail.yahoo.com> (raw)
Mr. Morton,
This patch: +drm-agp-module-dependency-fix.patch
has broken the radeon DRM driver under 2.6.0-test9-mm2. Enclosed is an e-mail I
sent to the dri-devel sourceforge list:
<snip>
I'm having problems using te DRI radeon driver in the 2.6.0-test9-mm2
kernel tree. When X is started, the kernel outputs these messages:
[drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held
[drm:radeon_unlock] *ERROR* Process 1083 using kernel context 0
The driver did not do this under 2.6.0-test9-mm1.
Interesting parts of dmesg (under 2.6.0-test9-mm2):
Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected an Intel i845 Chipset.
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: AGP aperture is 64M @ 0xec000000
[drm] Initialized radeon 1.9.0 20020828 on minor 0
I am using XFree86-4.3.0-42 from Fedora Core.
</snip>
Diffing the drivers/char/drm trees produces this, which I assume is the patch
you applied:
diff -urN linux-2.6.0-test9-mm1/drivers/char/drm/drm_agpsupport.h

I've had some responses from dri-devel so far, but right now I'm running
2.6.0-test9-mm1, which works perfectly fine.
What now?
TIA
Brad
