drm/amdgpu: fix sdma doorbell init ordering on APUs

2022-10-20T13:35:51+00:00

Commit 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()")
uncovered a bug in amdgpu that required a reordering of the driver
init sequence to avoid accessing a special register on the GPU
before it was properly set up leading to an PCI AER error.  This
reordering uncovered a different hw programming ordering dependency
in some APUs where the SDMA doorbells need to be programmed before
the GFX doorbells. To fix this, move the SDMA doorbell programming
back into the soc15 common code, but use the actual doorbell range
values directly rather than the values stored in the ring structure
since those will not be initialized at this point.

This is a partial revert, but with the doorbell assignment
fixed so the proper doorbell index is set before it's used.

drm/amdgpu: move nbio sdma_doorbell_range() into sdma code for vega

2022-09-14T18:21:43+00:00

This mirrors what we do for other asics and this way we are
sure the sdma doorbell range is properly initialized.

There is a comment about the way doorbells on gfx9 work that
requires that they are initialized for other IPs before GFX
is initialized.  However, the statement says that it applies to
multimedia as well, but the VCN code currently initializes
doorbells after GFX and there are no known issues there.  In my
testing at least I don't see any problems on SDMA.

This is a prerequisite for fixing the Unsupported Request error
reported through AER during driver load.

The error was unnoticed before and got visible because of the commit
referenced below. This doesn't fix anything in the commit below, rather
fixes the issue in amdgpu exposed by the commit. The reference is only
to associate this commit with below one so that both go together.

drm/amdgpu: move nbio ih_doorbell_range() into ih code for vega

2022-09-14T18:21:25+00:00

This mirrors what we do for other asics and this way we are
sure the ih doorbell range is properly initialized.

There is a comment about the way doorbells on gfx9 work that
requires that they are initialized for other IPs before GFX
is initialized.  In this case IH is initialized before GFX,
so there should be no issue.

drm/amd: fix gfx hang on renoir in IGT reload test

2022-03-15T18:34:45+00:00

[why]
CP hangs in igt reloading test on renoir, more precisely, hangs on the
second time insmod.

[how]
mode2 reset can make it recover, and mode2 reset only effects gfx core,
dcn and the screen will not be impacted.
