2023-10-09drm/amdkfd: get doorbell's absolute offset based on the db_sizeArvind Yadav
Here, Adding db_size in byte to find the doorbell's absolute offset for both 32-bit and 64-bit doorbell sizes. So that doorbell offset will be aligned based on the doorbell size. v2: - Addressed the review comment from Felix. v3: - Adding doorbell_size as parameter to get db absolute offset. v4: Squash the two patches into one.

2023-06-09drm/amdgpu: Use unique doorbell range per xccLijo Lazar
Program different ranges in each XCC with MEC_DOORBELL_RANGE_LOWER/HIGHER. Keeping the same range causes CPF in other XCCs also to be busy when an IB packet is submitted to KCQ. Only the XCC which processes the packet comes back to idle afterwards and this causes other CPs not be idle. This in turn affects clockgating behavior as RLC doesn't get idle interrupt. LOWER/HIGHER covers only KIQ/KCQs which are per XCC queues. Assigning different ranges doesn't seem to have any side effect as user queue ranges are outside of this range. User queue tests - PM4 through KFD and AQL through rocr - have the same results after this change.

2023-06-09drm/amdgpu: introduce new doorbell assignment table for GC 9.4.3Le Ma
Four basic reasons as below to do the change: 1. number of ring expand a lot on GC 9.4.3, and adjustment on old assignment cannot make each ring in a continuous doorbell space. 2. the SDMA doorbell index should not exceed 0x1FF on SDMA 4.2.2 due to regDOORBELLx_CTRL_ENTRY.BIF_DOORBELLx_RANGE_OFFSET_ENTRY field width. 3. re-design the doorbell assignment and unify the calculation as "start + ring/inst id" will make the code much concise. 4. only defining the START/END makes the table look simple v2: (Lijo) 1. replace name 2. use num_inst_per_aid/sdma_doorbell_range instead of hardcoding Signed-off-by: Le Ma <le.ma@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2023-06-09drm/amdgpu: assign the doorbell index for sdma on non-AID0Le Ma
Allocate new sdma doorbell index for the instances only on AID1 for now. Todo: there's limitation that SDMA doorbell index on SDMA 4.4.2 needs to be less than 0x1FF, so the tail part in _AMDGPU_VEGA20_DOORBELL_ASSIGNMENT is not enough to store sdma doorbell range on maximum 4 AIDs if doorbell_range is 20. So it looks better to create a new doorbell index assignment table for 4.4.2. v2: change "(x << 1) + 2" to "(x + 1) << 1" for readability.
