Bug ID: 94869
Summary: [BAT BSW] gem_ctx_param_basic/non-root-set-no-zeromap
causes *ERROR* gpu hanging too fast
Product: DRI
Version: DRI git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Intel
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: tim.gore at intel.com
QA Contact: intel-gfx-bugs at lists.freedesktop.org
CC: intel-gfx-bugs at lists.freedesktop.org
During BAT testing of a patch targeting gen9 only, several tests, of which
gem_ctx_param_basic/non-root-set-no-zeromap is one, cause "*ERROR* gpu hanging
too fast" in dmesg log on the bsw-nuc2 target, although the test reports
success.
This has also been seen in CI_DRM_1199 and CI_DRM_1175. Maybe related to bug
89633.
Patch being tested is https://patchwork.freedesktop.org/series/5367/
This introduces a workaround in gen9_init_workarounds, which is also
conditional on
(IS_SKL_REVID(dev, SKL_REVID_C0, REVID_FOREVER) || IS_BROXTON(dev))
So this patch should not be able to affect a BSW target.
Regression build. CI_DRM_1200
