2023-10-09T21:02:34+00:00

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.

drm/amdgpu: Use unique doorbell range per xcc

2023-06-09T13:52:06+00:00

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. Signed-off-by: Lijo Lazar Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher
