drm/amdgpu: add new doorbell assignment table for aqua_vanjaram
Four basic reasons as below to do the change: 1. number of ring expand a lot on aqua_vanjaram, and adjustment on old assignment cannot make each ring in a continuous doorbell space. 2. the SDMA doorbell index should not exceed 0x1FF on aqua_vanjaram 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 <[email protected]> Reviewed-by: Lijo Lazar <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
