Bug ID: 111858 Summary: [ICL] IGT tests kms_ccs and kms_frontbuffer_tracking fail on latest drm-tip kernel Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: not set Component: IGT Assignee: dri-devel@lists.freedesktop.org Reporter: yue.he@intel.com

Created attachment 145585 --> https://bugs.freedesktop.org/attachment.cgi?id=145585&action=edit kms_frontbuffer_tracking

On Ubuntu 16.04 on ICL-U D0 board, replace kernel to 5.3.0-rc8: git clone https://github.com/freedesktop/drm-tip Then git clone https://gitlab.freedesktop.org/drm/igt-gpu-tools.git Build igt test tool. Then run the igt test on console terminal as root ./kms_ccs IGT-Version: 1.24-g924e5c5 (x86_64) (Linux: 5.3.0-rc8 x86_64) Subtest pipe-A-crc-primary-basic: CRASH (0.004s) Starting subtest: pipe-A-crc-primary-rotation-180 Subtest pipe-A-crc-primary-rotation-180: CRASH (0.004s) Starting subtest: pipe-A-crc-sprite-planes-basic Starting subtest: pipe-B-crc-primary-basic Subtest pipe-B-crc-primary-basic: CRASH (0.001s) Starting subtest: pipe-B-crc-primary-rotation-180 Subtest pipe-B-crc-primary-rotation-180: CRASH (0.001s) The 4 tests are crash.

Run the gem_basic, the subtests of gem_basic are all pass.

Run the ./ kms_frontbuffer_tracking, there are error: Stack trace: #0 /home/hdr/igt-gpu-tools/lib/igt_core.c:1696 __igt_fail_assert() #1 /home/hdr/igt-gpu-tools/tests/kms_frontbuffer_tracking.c:1274 __real_main3273() #2 /home/hdr/igt-gpu-tools/tests/kms_frontbuffer_tracking.c:3273 main() #3 ../csu/libc-start.c:325 __libc_start_main() #4 [_start+0x29] #5 [<unknown>+0x0] And all subtest fail.
