drm/amdkfd: Make sched_policy a per-device setting

2018-01-04T22:17:43+00:00

Some dGPUs don't support HWS. Allow them to use a per-device sched_policy that may be different from the global default. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Add debugfs support to KFD

2017-11-27T23:29:49+00:00

This commit adds several debugfs entries for kfd: kfd/hqds: dumps all HQDs on all GPUs for KFD-controlled compute and SDMA RLC queues kfd/mqds: dumps all MQDs of all KFD processes on all GPUs kfd/rls: dumps HWS runlists on all GPUs Signed-off-by: Yong Zhao Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Add crash protection in debugger register path

2017-11-27T23:29:44+00:00

After debugger is registered, the pqm_destroy_queue fails because is_debug is true, the queue should not be removed from process_queue_list since the count is not reduced. Test application calls debugger unregister without register debugger, add null pointer check protection to avoid crash for this case Signed-off-by: Philip Yang Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Cleanup qpd.pqm initialization

The PQM doesn't change after process creation. So initialize it in kfd_create_process_device_data. Signed-off-by: Felix Kuehling Signed-off-by: Oded Gabbay

drm/amdkfd: Fix SDMA oversubsription handling

2017-11-26T09:31:32+00:00

SDMA only supports a fixed number of queues. HWS cannot handle oversubscription. Signed-off-by: shaoyun liu Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Register/Deregister process on qpd resolution

2017-11-01T23:21:30+00:00

Process registration needs to happen on each device. So use per-device queue lists to determine when to register/deregister the process. Signed-off-by: Ben Goz Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Limit queue number per process and device to 127

2017-09-27T04:09:55+00:00

HWS uses bit 7 in the queue number of the map process packet for an undocumented feature. Therefore the queue number per process and device must be 127 or less. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Clean up process queue management

Removed unused num_concurrent_processes. Implemented counting of queues in QPD. This makes counting the queue list repeatedly in several places unnecessary. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay
