drm/amdkfd: New IOCTL to allocate queue GWS (v2)

2020-04-28T20:20:30Z

Add a new kfd ioctl to allocate queue GWS. Queue GWS is released on queue destroy. v2: re-introduce this API with the following fixes squashed in: - drm/amdkfd: fix null pointer dereference on dev - drm/amdkfd: Return proper error code for gws alloc API - drm/amdkfd: Remove GPU ID in GWS queue creation Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Delete unnecessary unmap queue package submissions

2020-02-26T19:20:33Z

The previous way of using SDMA queue count to infer whether we should unmap SDMA engines has bugs. The reason it did not cause issues is because MEC firmware unmaps all queues (CP + SDMA) when a unmap package for compute engine is received. Becasue of that, only one unmap queue package is needed, instead of one unmap queue package for CP and each SDMA engine, which results in much simpler driver code.

drm/amdkfd: Add queue information to sysfs

2020-02-06T20:04:38Z

Provide compute queues information in sysfs under /sys/class/kfd/kfd/proc. The format is /sys/class/kfd/kfd/proc//queues//XX where XX are size, type, and gpuid three files to represent queue size, queue type, and the GPU this queue uses. folder and files underneath are generated when a queue is created. They are removed when the queue is destroyed. Signed-off-by: Amber Lin Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

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
