Also, see bug 104693 and bug 104694 commit bd724318b682587ad2f989ab8e0f7b3d4486ced5 Author: Michal Wajdeczko <michal.wajdeczko@intel.com> Date: Fri Jan 19 12:49:26 2018 +0000 drm/i915/guc: Keep GuC log disabled by default It looks that GuC log functionality is not fully functional yet and causes issues when enabled by auto(-1) modparam on debug builds. For example, but not limited to: [ 30.062893] ====================================================== [ 30.062894] WARNING: possible circular locking dependency detected [ 30.062895] 4.15.0-rc8-CI-CI_DRM_3648+ #1 Tainted: G U [ 30.062896] ------------------------------------------------------ [ 30.062897] debugfs_test/1268 is trying to acquire lock: [ 30.062898] (&dev->struct_mutex){+.+.}, at: [<00000000e4213449>] i915_mutex_lock_interruptible+0x47/0x130 [i915] [ 30.062921] but task is already holding lock: [ 30.062921] (&mm->mmap_sem){++++}, at: [<00000000dd7adc93>] __do_page_fault+0x106/0x560 [ 30.062924] which lock already depends on the new lock.

I can't close the bug, since I know that the issue is still there. However, I will archive from cibuglog. Hi Marta, Fix has been merged for this today https://patchwork.freedesktop.org/patch/200405/ CI BAT also confirmed resolution with GuC log enabled by default. But change to enable GuC log by default is gated by https://bugs.freedesktop.org/show_bug.cgi?id=104694 and will be addressed next. Can we mark this bug as CLOSED now. Thanks, Sagar |
