2021-07-23drm/amdgpu: Clear doorbell interrupt status for Sienna CichlidChengzhe Liu
On Sienna Cichlid, in pass-through mode, if we unload the driver in BACO mode(RTPM), then the kernel would receive thousands of interrupts. That's because there is doorbell monitor interrupt on BIF, so KVM keeps injecting interrupts to the guest VM. So we should clear the doorbell interrupt status after BACO exit. v2: Modify coding style and commit message Signed-off-by: Chengzhe Liu <ChengZhe.Liu@amd.com> Reviewed-by: Luben Tuikov <luben.tuikov@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2021-06-30drm/amdgpu: fix the hang caused by PCIe link width switchEvan Quan
SMU had set all the necessary fields for a link width switch but the width switch wasn't occurring because the link was idle in the L1 state. Setting LC_L1_RECONFIG_EN=0x1 will allow width switches to also be initiated while in L1 instead of waiting until the link is back in L0.

2020-04-01drm/amdgpu: cleanup all virtualization detection routineMonk Liu
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).
