drm/amdkfd: Check HIQ's MQD for queue preemption status

2021-03-24T02:59:25+00:00

MEC firmware can silently fail the queue preemption request without time out. In this case, HIQ's MQD's queue_doorbell_id will be set. Check this field to see whether last queue preemption was successful or not. Signed-off-by: Oak Zeng Suggested-by: Jay Cornwall Acked-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Shift sdma_engine_id and sdma_queue_id in mqd

2019-05-24T17:21:01+00:00

FW of some new ASICs requires sdma mqd size to be not more than 128 dwords. Repurpose the last 2 reserved fields of sdma mqd for driver internal use, so the total mqd size is no bigger than 128 dwords Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu/gfx8: move CE&DE meta data structure to vi_structs.h

2017-03-30T03:53:31+00:00

Because different HWs have different definition for CE & DE meta data, follow mqd design to move the structures to vi_structs.h. And change the prefix from amdgpu to vi as the structures is only for VI family. Signed-off-by: Xiangliang Yu Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Add amdgpu <--> amdkfd gfx8 interface

2015-07-20T06:16:48+00:00

This patch adds the gfx8 interface file between amdgpu and amdkfd. This interface file is currently in use when running on a Carrizo-based system. The interface itself is represented by a pointer to struct kfd_dev. The pointer is located inside amdgpu_device structure. All the register accesses that amdkfd need are done using this interface. This allows us to avoid direct register accesses in amdkfd proper, while also allows us to avoid locking between amdkfd and amdgpu. The single exception is the doorbells that are used in both of the drivers. However, because they are located in separate pci bar pages, the danger of sharing registers between the drivers is minimal. Having said that, we are planning to move the doorbells as well to amdgpu.
