drm/amdkfd: Avoid hanging hardware in stop_cpsch

2020-01-07T16:55:04Z

Don't use the HWS if it's known to be hanging. In a reset also don't try to destroy the HIQ because that may hang on SRIOV if the KIQ is unresponsive. Signed-off-by: Felix Kuehling Tested-by: Emily Deng Reviewed-by: shaoyunl Signed-off-by: Alex Deucher

drm/amdkfd: Rename create_cp_queue() to init_user_queue()

2019-11-13T20:29:45Z

create_cp_queue() could also work with SDMA queues, so we should rename it. It only initialize the data values rather than creating queues. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Avoid using doorbell_off as offset in process doorbell pages

2019-11-13T20:29:45Z

dorbell_off in the queue properties is mainly used for the doorbell dw offset in pci bar. We should not set it to the doorbell byte offset in process doorbell pages. This makes the code much easier to read. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Use hex print format for pasid

2019-10-03T14:11:03Z

Since KFD pasid starts from 0x8000 (32768 in decimal), it is better perceived as a hex number. Meanwhile, change the pasid type from unsigned int to uint16_t to be consistent throughout the code. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

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

2019-05-24T17:21:02Z

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.
