Description Tim Miller 2002-07-12 11:42:53 EDT

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020606

Description of problem:
When upgrading my RH7.3 kernel from 2.4.18-3 to 2.4.18-5, I lost
direct rendering on my IBM Thinkpad A30 (Radeon Mobility).  I
traced the issue to kernel modules that did not load because
they were not PRESENT in the kernel package.


Version-Release number of selected component (if applicable): 2.4.18-5


How reproducible:
Always

Steps to Reproduce:
/lib/modules# find . -name "radeon*"
./2.4.18-3/kernel/drivers/char/drm/radeon.o
./2.4.18-3/kernel/drivers/video/radeonfb.o
./2.4.18-5/kernel/drivers/video/radeonfb.o



Actual Results:  When booting 2.4.18-5, chromium game is painfully slow.  Graphics
are jerky and unplayable.  When booting 2.4.18-3 (NO OTHER CHANGES),
chromium game plays just fine.

Comment 1 Arjan van de Ven 2002-07-12 11:46:43 EDT

Ok I bet the following is the case:

you installed the i386 kernel (instead of the i586, i686 or athlon one)

the i386 kernel doesn't have DRM support, the i586, i686 or athlon kernels DO
have DRM support....

is my assumption correct ?

Comment 2 Tim Miller 2002-07-12 19:08:33 EDT

That was the problem.  I didn't realize I had installed the i386
kernel for one thing but I also didn't think it mattered.  Why
isn't DRM in i386?  (I am by far NOT a video guru)

Comment 3 Arjan van de Ven 2002-07-13 04:02:05 EDT

The DRM code internally uses CPU instructions that are not available on a
80386......
