drm/amdgpu: Fix fall-through warnings for Clang

2020-11-24T17:05:36+00:00

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
warnings by explicitly adding multiple break statements instead of just
letting the code fall through to the next case.

drm/amdgpu: note what type of reset we are using

2020-08-14T21:03:20+00:00

When we reset the GPU, note what type of reset will be
used.  This makes debugging different reset scenarios
more clear as the driver may use different reset
methods depending on conditions on the system.

drm/amdgpu: add module parameter choose reset mode

2020-07-15T16:42:01+00:00

Default value is auto, doesn't change
original reset method logic.

v2: change to use parameter reset_method
v3: add warn msg if specified mode isn't supported

drm/amdgpu: request init data in virt detection

2020-07-02T16:02:50+00:00

Move request init data to virt detection func, so we
can insert request full access between request init data
and set ip blocks.

drm/amdgpu: cleanup all virtualization detection routine

2020-04-01T18:44:42+00:00

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).

drm/amd/powerplay: cover the powerplay implementation details V3

2020-01-14T15:18:08+00:00

This can save users much troubles. As they do not
actually need to care whether swSMU or traditional
powerplay routine should be used.

V2: apply the fixes to vi.c and cik.c also
V3: squash in oops fix
