commit 5599239c331b9860c35d5e0fd7c6acbc838fc20d Author: Monk Liu Monk.Liu@amd.com Date: Tue Apr 19 20:11:32 2016 +0800

drm/amdgpu: keep vm in job instead of ib

ib.vm is a legacy way to get vm, after scheduler implemented vm should be get from job, and all ibs from one job share the same vm, no need to keep ib.vm just move vm field to job.

this patch as well add job as paramter to ib_schedule so it can get vm from job->vm.

Easy to provoke with powerplay=1 and auto clocks. Harder to provoke, but also happens with powerplay=0.

dmesg with Oops attached.
