[PATCH 02/11] drm/amdkfd: Fix suspend/resume issue on Carrizo

2017-09-15 Thread Felix Kuehling
From: Yong Zhao When we do suspend/resume through "sudo pm-suspend" while there is HSA activity running, upon resume we will encounter HWS hanging, which is caused by memory read/write failures. The root cause is that when suspend, we neglected to unbind pasid from kfd device.
