drm/amdkfd: Add TC flush on VMID deallocation for Hawaii

2018-03-15T21:27:50Z

On GFX7 the CP does not perform a TC flush when queues are unmapped. To avoid TC eviction from accessing an invalid VMID, flush it explicitly before releasing a VMID. v2: Fix unnecessary list_for_each_entry_safe v3: Moved allocation to kfd_process_device_init_vm Signed-off-by: Amber Lin Signed-off-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Oded Gabbay

drm/amdkfd: Add debugfs support to KFD

drm/amdkfd: map multiple processes to HW scheduler

2017-11-27T23:29:45Z

Allow HWS to to execute multiple processes on the hardware concurrently. The number of concurrent processes is limited by the number of VMIDs allocated to the HWS. A module parameter can be used for limiting this further or turn it off altogether (mainly for debugging purposes).

drm/amdkfd: Improve multiple SDMA queues support per process

2017-09-27T04:09:56Z

HWS does not support over-subscription and the scheduler can not internally modify the engine. Driver needs to program the correct engine ID. Fix the queue and engine selection to create queues on alternating SDMA engines. This allows concurrent bi-directional DMA transfers in a process that creates two SDMA queues.

drm/amdkfd: Avoid name confusion involved in queue unmapping

2017-09-27T04:09:48Z

When unmapping the queues from HW scheduler, there are two actions: reset and preempt. So naming the variables with only preempt is inapproriate. For functions such as destroy_queues_cpsch, what they do actually is to unmap the queues on HW scheduler rather than to destroy them. Change the name to reflect that fact. On the other hand, there is already a function called destroy_queue_cpsch() which exactly destroys a queue, and the name is very close to destroy_queues_cpsch(), resulting in confusion.
