Bug ID: 88301
Summary: Dota causes GPU fault and kernel hang
Product: DRI
Version: DRI git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel at lists.freedesktop.org
Reporter: tilman at code-monkey.de
I've got an apitrace of Dota that reliably causes GPU faults on radeonsi on my
Bonaire XTX.
The trace: http://files.code-monkey.de/dota.trace (468797931 bytes).
I'm running Mesa from master (8d2542fc9d5af4db355b67cc2a1ff2f413685a27) and can
reproduce the problem with kernel 3.18.2 and 3.19.0-rc2 (built from airlied's
drm-fixes tree; 79305ec6e60d320832505e95c1a028d309fcd2b6).
agd5f's "fix VM flush" patches from 2015-01-06 don't help either.
Example kernel log excerpt:
radeon 0000:01:00.0: GPU fault detected: 147 0x000c4801
radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x01000000
