drm/amdkfd: Add wavefront context save state retrieval ioctl

2018-09-27T02:09:15Z

Wavefront context save data is of interest to userspace clients for debugging static wavefront state. The MQD contains two parameters required to parse the control stack and the control stack itself is kept in the MQD from gfx9 onwards. Add an ioctl to fetch the context save area and control stack offsets and to copy the control stack to a userspace address if it is kept in the MQD.

drm/amdkfd: Add CU-masking ioctl to KFD

2018-07-14T23:05:59Z

CU-masking allows a KFD client to control the set of CUs used by a user mode queue for executing compute dispatches. This can be used for optimizing the partitioning of the GPU and minimize conflicts between concurrent tasks.

drm/amdkfd: Make SDMA engine number an ASIC-dependent variable

2018-07-13T20:17:44Z

On Raven there is only one SDMA engine instead of previously assumed two, so we need to adapt our code to this new scenario. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Felix Kuehling Acked-by: Alex Deucher Signed-off-by: Oded Gabbay

drm/amdkfd: Implement doorbell allocation for SOC15

2018-04-10T21:33:05Z

Allocate doorbells according to the doorbell routing information on SOC15 ASICs (Vega10 and later). On older ASICs we continue to use the queue_id as the doorbell ID to maintain compatibility with the Thunk.

drm/amdkfd: Add crash protection in debugger register path

2017-11-27T23:29:44Z

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.
