QA, please re-test It should still die unless they have a machine with more memory... Increasing priority due to current platform experience impact (In reply to Chris Wilson from comment #2) > It should still die unless they have a machine with more memory... Hi Chris : it would be great if you can tell us with are the exact amount of memory that we need in order to run this test, because looks like that the ram for KBL (4GB) / APL (8GB) is not enough right ? as information APL & KBL support until 16GB but the ram in KBL is imbibed which mean that we are not able to increase it, only we can do it in BXT-P meanwhile this test is fail on BXT-P with the following configuration test : igt@gem_ctx_thrash@threads test output =============================== (gem_ctx_thrash:1941) igt-core-DEBUG: Test requirement passed: !igt_run_in_simulation() (gem_ctx_thrash:1941) igt-core-DEBUG: Starting subtest: threads Creating 98304 contexts (assuming of size 65536) (gem_ctx_thrash:1941) intel-os-DEBUG: Checking 98,304 surfaces of size 65,536 bytes (total 6,492,782,592) against RAM + swap (gem_ctx_thrash:1941) intel-os-DEBUG: Test requirement passed: __intel_check_memory(count, size, mode, &required, &total) (gem_ctx_thrash:1941) igt-core-DEBUG: Test requirement passed: !igt_run_in_simulation() (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: Test assertion failure function gem_execbuf, file ioctl_wrappers.c:589: (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: Failed assertion: __gem_execbuf(fd, execbuf) == 0 (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: error: -5 != 0 Stack trace: (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: Test assertion failure function gem_execbuf, file ioctl_wrappers.c:589: #0 [__igt_fail_assert+0x101] #1 [gem_execbuf+0x44] #2 [thread+0xb1] #3 [start_thread+0xca] #4 [clone+0x6d] (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: Failed assertion: __gem_execbuf(fd, execbuf) == 0 (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: error: -5 != 0 Stack trace: #0 [__igt_fail_assert+0x101] #1 [gem_execbuf+0x44] #2 [thread+0xb1] #3 [start_thread+0xca] #4 [clone+0x6d] #5 [<unknown>+0x6d] Subtest threads failed. #5 [<unknown>+0x6d] **** DEBUG **** (gem_ctx_thrash:1941) INFO: Creating 98304 contexts (assuming of size 65536) (gem_ctx_thrash:1941) intel-os-DEBUG: Checking 98,304 surfaces of size 65,536 bytes (total 6,492,782,592) against RAM + swap (gem_ctx_thrash:1941) intel-os-DEBUG: Test requirement passed: __intel_check_memory(count, size, mode, &required, &total) (gem_ctx_thrash:1941) igt-core-DEBUG: Test requirement passed: !igt_run_in_simulation() (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: Test assertion failure function gem_execbuf, file ioctl_wrappers.c:589: (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: Failed assertion: __gem_execbuf(fd, execbuf) == 0 (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: error: -5 != 0 (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: Test assertion failure function gem_execbuf, file ioctl_wrappers.c:589: (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: Failed assertion: __gem_execbuf(fd, execbuf) == 0 (gem_ctx_thrash:1941) ioctl-wrappers-CRITICAL: error: -5 != 0 **** END **** Subtest threads: FAIL (6.782s) Subtest threads failed.

Enough to hit oom on some machines. References: https://bugs.freedesktop.org/show_bug.cgi?id=94145 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> should factor execlists into account for memory usage and so prevent further oom. The GPU hang is another bug... Test is Pass on KBL-U. It needs 4660,198s. Tested with intel-gpu-tools 1.15 f5d370c from http://anongit.freedesktop.org/git/xorg/app/intel-gpu-tools.git Please open another bug for APL. |
