2017-09-20drm/amdkfd: Adjust dequeue latencies and timeoutsFelix Kuehling5-7/+6
Adjust latencies and timeouts for dequeueing with HWS and consolidate them in one place. Make them longer to allow long running waves to complete without causing a timeout. The timeout is twice as long as the latency plus some buffer to make sure we don't detect a timeout prematurely. Change timeouts for dequeueing HQDs without HWS. KFD_UNMAP_LATENCY is more consistent with what the HWS does for user queues.

2017-09-20drm/amdkfd: Fix suspend/resume issue on Carrizo v2Yong Zhao4-39/+109
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. Another major change is that the bind/unbinding is changed to be performed on a per process basis, instead of whether there are queues in dqm. v2: - free IOMMU device if kfd_bind_processes_to_device fails in kfd_resume - add comments to kfd_bind/unbind_processes_to/from_device - minor cleanups Signed-off-by: Yong Zhao <yong.zhao@amd.com> Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Reviewed-by: Oded Gabbay <oded.gabbay@gmail.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

Apart from adding the helper function itself, the rest of the kernel is converted mechanically using: git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_count);/mmgrab\(\1\);/' git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)\.mm_count);/mmgrab\(\&\1\);/' This is needed for a later patch that hooks into the helper, but might be a worthwhile cleanup on its own. (Michal Hocko provided most of the kerneldoc comment.)

2017-01-16drm/amdkfd: fix improper return value on errorPan Bian1-1/+3
In function kfd_wait_on_events(), when the call to copy_from_user() fails, the value of return variable ret is 0. 0 indicates success, which is inconsistent with the execution status. This patch fixes the bug by assigning "-EFAULT" to ret when copy_from_user() returns an unexpected value.
