drm/amdkfd: Remove GWS from process during uninit

2019-07-17T18:34:31Z

If we shut down a process without having destroyed its GWS-using queues, it is possible that GWS BO will still be in the process BO list during the gpuvm destruction. This list should be empty at that time, so we should remove the GWS allocation at the process uninit point if it is still around.

drm/amdkfd: Add function to set queue gws

2019-05-28T19:44:24Z

Add functions in process queue manager to set/unset queue gws. Also set process's number of gws used. Currently only one queue in process can use and use all gws. Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Introduce XGMI SDMA queue type

Existing QUEUE_TYPE_SDMA means PCIe optimized SDMA queues. Introduce a new QUEUE_TYPE_SDMA_XGMI, which is optimized for non-PCIe transfer such as XGMI. Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Init mqd managers in device queue manager init

2019-05-24T17:21:02Z

Previously mqd managers was initialized on demand. As there are only a few type of mqd managers, the on demand initialization doesn't save too much memory. Initialize them on device queue initialization instead and delete the get_mqd_manager interface. This makes codes more organized for future changes.

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.

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
