drm/amdkfd: Remove cu mask from struct queue_properties(v2)

2021-10-28T18:26:13+00:00

Actually, cu_mask has been copied to mqd memory and does't have to persist in queue_properties. Remove it from queue_properties. And use struct mqd_update_info to store such properties, then pass it to update queue operation. v2: * Rename pqm_update_queue to pqm_update_queue_properties. * Rename struct queue_update_info to struct mqd_update_info. * Rename pqm_set_cu_mask to pqm_update_mqd.

drm/amdkfd: Add an optional argument into update queue operation(v2)

2021-10-28T18:26:13+00:00

Currently, queue is updated with data in queue_properties. And all allocated resource in queue_properties will not be freed until the queue is destroyed. But some properties(e.g., cu mask) bring some memory management headaches(e.g., memory leak) and make code complex. Actually they have been copied to mqd and don't have to persist in queue_properties. Add an argument into update queue to pass such properties, then we can remove them from queue_properties. v2: Don't use void *.

drm/amdkfd: fix sysfs kobj leak

2021-06-30T04:18:23+00:00

3 cases of kobj leak, which causes memory leak: kobj_type must have release() method to free memory from release callback. Don't need NULL default_attrs to init kobj. sysfs files created under kobj_status should be removed with kobj_status as parent kobject. Remove queue sysfs files when releasing queue from process MMU notifier release callback. Signed-off-by: Philip Yang Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: replace per_device_list by array

2021-04-09T20:41:52+00:00

Remove per_device_list from kfd_process and replace it with a kfd_process_device pointers array of MAX_GPU_INSTANCES size. This helps to manage the kfd_process_devices binded to a specific kfd_process. Also, functions used by kfd_chardev to iterate over the list were removed, since they are not valid anymore. Instead, it was replaced by a local loop iterating the array. Signed-off-by: Alex Sierra Signed-off-by: Felix Kuehling Reviewed-by: Jonathan Kim Signed-off-by: Alex Deucher

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

2020-04-28T20:20:30+00:00

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

2020-02-26T19:20:33+00:00

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.
