From 3aa0115d238c71423d0e212138678a8cf51d4361 Mon Sep 17 00:00:00 2001 From: Monk Liu Date: Wed, 4 Mar 2020 14:02:55 +0800 Subject: drm/amdgpu: cleanup all virtualization detection routine 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).
