kernel bootup output

module options for radeon: modeset=1 audio=0 dynclks=1 dynpm=1

* Notes: While I was trying to fiddle with VBOs in Second Life the drm spit out:
radeon 0000:01:00.0: vbo resource seems too big for the bo

No matter what VRAM size set, 256 and texture memory of 192, or 128MB vram and texture memory of  96MB (you can set what the game 'thinks' is the most memory available, it attempts and fails to look at the Xorg log file for VRAM info (the string changed and thus broke this code it falls back to 128MB)

I don't think this had anything to do to trigger this, but that error is alarming nonetheless.

Crash below:

crashdump (easier to read than in bug)

Comment 2 Shawn Starr 2010-02-05 00:38:28 UTC

From Dave Airlie: Thats the CS checker code from glisse. He'll need to test when he gets back from FOSDEM

Comment 3 Shawn Starr 2010-02-11 19:56:18 UTC

Attaching new crash info: This is 2.6.33-rc7 and any of linus's changes merged in linux-2.6: drm-linus, drm-core-next, drm-next and drm-radeon-testing.

crash dump from today

Comment 5 Shawn Starr 2010-02-12 14:49:51 UTC

Today's crash information:

playing Second Life, I managed to trigger a drm error that did not lock up GPU, a 2nd time trying the same steps resulted in the GPU lockup with a kernel oops:

1) in Second Life, I started game, did not have VBOs on and it used the default 128MB for textures
2) Set texture memory size to 256MB (max limit in drm right now) and enable VBO support.

Results:

Feb 12 15:53:56 segfault kernel: [  838.349029] [drm:radeon_ib_get] *ERROR* IB 8 scheduled without a fence.
Feb 12 15:53:56 segfault kernel: [  838.349033] [drm:radeon_cs_ioctl] *ERROR* Failed to get ib !

Took off VBOs for a bit then reenabled them and kernel panic'd not long after:

Created attachment 33310 [details] [review]
Add free flag for ib

Please test with that one hopefully it should fix the kref/ib issue

Comment 8 Fabio Pedretti 2010-02-26 01:17:03 UTC

Patch applied in 2.6.33.
