Created attachment 126881 [details] Dmesg with load and submission value 2 i'm facing some issue running basic IGT tests with GUC 6.1 enabled, sharing my configuration. GuC 6.1: https://01.org/linuxgraphics/downloads/skylake-guc-6.1 Kernel: 4.8.0-rc7_3c9e639/ Commit git_commit=3c9e639197bb52280334830e611082d5b6bfaceb Intel Gpu Tools : intel-gpu-tools-1.16-36-gd16318a Hardware: : Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz Behavior: In a 244 test suites, after i got the first time out, all the others tests still facing the same behavior taking more than 10 minutes to execute, this causes a time out signal failing the test. Something completely different if i disable guc deleting values from grub.( i915.enable_guc_loading=2 i915.enable_guc_submission=2) Steps to reproduce: Enable guc using grub parameters after installing firmware (i915.enable_guc_loading=2 i915.enable_guc_submission=2).

Updated to highest blocker. It is causing our DUTs to be very slow when executing full IGT.
Yann found this is due to test gem_ringfill. It is not reproduced when blacklisting it.
Reduced from Highest to High since failure is not visible with default config/settings.
If you have time, can you run this experiment? 1. grub parameters: i915.enable_guc_loading=2 i915.enable_guc_submission=2 i915.guc_log_level=2 drm.debug=0xe 2. run these tests (stop if one of the tests already timeout): gem_ringfill --run-subtest basic-default gem_ringfill --run-subtest basic-default-interruptible gem_ringfill --run-subtest basic-default-hang gem_ringfill --run-subtest basic-default-forked 3. get these logs: dmesg cat /sys/kernel/debug/dri/0/i915_guc_log_dump > ~/guc_log_dump.log cat /sys/kernel/debug/dri/0/i915_guc_info > ~/timeout_info.log cat /sys/kernel/debug/dri/0/i915_gem_seqno >> ~/timeout_info.log cat /sys/kernel/debug/dri/0/i915_gem_request >> ~/timeout_info.log And attach those 3 files (dmesg, guc_log & timeout_info).

Elio, please try Michal's patch: https://patchwork.freedesktop.org/series/13388/
https://patchwork.freedesktop.org/series/13388/ Fixes the problem on SKL, but the issue does not depend on HW/GuC version
Patch from Chris also fixes the issue: https://patchwork.freedesktop.org/patch/114110/ You should probably ignore my version.
