Priority: medium Bug ID: 71983 Assignee: dri-devel@lists.freedesktop.org Summary: libdrm 2.4.49 makes gpu crash (HD7770) Severity: normal Classification: Unclassified OS: All Reporter: arek.rusi@gmail.com Hardware: Other Status: NEW Version: git Component: Drivers/Gallium/radeonsi Product: Mesa
Created attachment 89740 --> https://bugs.freedesktop.org/attachment.cgi?id=89740&action=edit kernel log when i run some ogl apps (unigine-*;some 3d games; even google-chrome)
I've gzipped log because it has ~ 14MB.
main part are bazillion lines like that: <3>[ 414.876442] radeon 0000:01:00.0: GPU fault detected: 146 0x0fe32004 <3>[ 414.876446] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x000021FF <3>[ 414.876448] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x03020004 <4>[ 414.876450] VM fault (0x04, vmid 1) at page 8703, write from CB (32) <3>[ 414.876455] radeon 0000:01:00.0: GPU fault detected: 146 0x0fc32004 <3>[ 414.876457] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000 <3>[ 414.876458] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x00000000 <4>[ 414.876460] VM fault (0x00, vmid 0) at page 0, read from unknown (0)
Usually my PC doesn't respone but sometimes like for unigine-sanctuary i can see graphics corruption for a while. When i downgrade libdrm everything works like before.

http://cgit.freedesktop.org/mesa/drm/commit/?id=ce8af454259279c14c44bcd32c42...
btw i try turn off tiling but without succes, gpu still crashes. Before this commit it works ok.

--- Comment #5 from Dave Witbrodt dawitbro@sbcglobal.net --- Same problem here on HD 7850 (PITCAIRN 0x1002:0x6819 0x1787:0x2320).
Yesterday I was upgrading my X server to test 1.15 RC2, which requires some libraries not available on Debian yet. All was well when I began:
libdrm : 2.4.48 mesa : 10.1.0-devel (commit 53f89a43 of Nov. 17) xorg-server: 1.14.99.3 radeon DDX : 7.2.99 (commit d571d6af of Nov. 13) glamor : 0.5.1 (commit 890a7738 of Nov. 6) linux : 3.12.1 (+ some DRM from 3.13rc1)
I had some build failures last time I tried to update the X server, and I saw bigger than usual changes coming for 1.15, so I thought I should invest some time into trying to get things working. After getting the dependencies satisfied and having succesfully built 1.14.99.902 (with the drivers rebuilt against it) everything was fine. In fact, I saw a very noticeable performance boost. On a roll, I decided to update Mesa and libdrm, ending up with this set of packages:
libdrm : 2.4.49 mesa : 10.1.0-devel (commit f56f875b of Nov. 21) xorg-server: 1.14.99.902 radeon DDX : 7.2.99 (commit d571d6af of Nov. 13) glamor : 0.5.1 (commit 71e7168d of Nov. 13) linux : 3.12.1 (+ some DRM from 3.13rc1)
That's when it all stopped working. Even downgrading the X stack and Mesa (in any combination) to the previous working versions still causes failures. The symptoms are that everything seems to be fine (kernel boots, X starts, you can use the desktop, etc.) until you touch OpenGL. Any attempt to try a game like 'torcs' (or even 'prboom-plus', which is much less GL intensive) causes X to freeze. It is sometimes possible to switch to a VT, but the screen goes black in a few moments so there is nothing to see; if the system does not reboot on its own, it is possible to use sysrq keys to shut it down somewhat sanely.
When changing everything back (except libdrm) to previous working versions _also_ was not working, I began to suspect libdrm. After downgrading to libdrm 2.4.48, everything was working again flawlessly; even upgrading Mesa and the X stack continued to work perfectly, so I can once again enjoy the 1.15 performance improvements!
It took so many hours to identify libdrm 2.4.49 as the culprit -- I was assuming that xorg-server, mesa, or glamor were at fault -- that I ran out of time last night. I only have to work 2 days this week, so I should be able to bisect it in 2 days (if no developer can reproduce it by then).

Does this patch fix the problem?
