drm/amdgpu: cleanup all virtualization detection routine

2020-04-01T18:44:42Z

we need to move virt detection much earlier because: 1) HW team confirms us that RCC_IOV_FUNC_IDENTIFIER will always be at DE5 (dw) mmio offset from vega10, this way there is no need to implement detect_hw_virt() routine in each nbio/chip file. for VI SRIOV chip (tonga & fiji), the BIF_IOV_FUNC_IDENTIFIER is at 0x1503 2) we need to acknowledged we are SRIOV VF before we do IP discovery because the IP discovery content will be updated by host everytime after it recieved a new coming "REQ_GPU_INIT_DATA" request from guest (there will be patches for this new handshake soon).

2020-01-14T15:18:09Z

guest vm gets 0xffffffff when reading RCC_DEV0_EPF0_STRAP0, as a consequence, the rev_id and external_rev_id are wrong. workaround it by hardcoding the rev_id to 0, which is the default value. v2. add comment in the code Signed-off-by: Tiecheng Zhou Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher
