[ Upstream commit f1c2cd3f8fb959123a9beba18c0e8112dcb2e137 ]

The ROMC_INDEX/DATA offset was changed to e4/e5 since
from smuio_v11 (vega20/arcturus).

commit 5bbc6604a62814511c32f2e39bc9ffb2c1b92cbe upstream.

The offset into the array was specified in bytes but should
be in terms of 32-bit words.  Also prevent large reads that
would also cause a buffer overread.

v2:  Read from correct offset from internal storage buffer.

[ Upstream commit 2ab7e274b86739f4ceed5d94b6879f2d07b2802f ]

The TDR will be randomly failed due to compute ring
test failure. If the compute ring wptr &amp; 0x7ff(ring_buf_mask)
is 0x100 then after map mqd the compute ring rptr will be
synced with 0x100. And the ring test packet size is also 0x100.
Then after invocation of amdgpu_ring_commit, the cp will not
really handle the packet on the ring buffer because rptr is equal to wptr.

Use a more meaningful variable name for the invalidation request
that is distinct from the tmp variable that gets overwritten when
acquiring the invalidation semaphore.

Variable grph_obj_type is being assigned twice, one of these is
redundant so remove it.

    drm/amdgpu: drop deprecated drm_get_pci_dev and drm_put_dev

No idea whether this was intentional or accidental breakage, but I
guess anyone who manages to boot a this modern gpu behind an agp
bridge deserves a price. A price I never expect anyone to ever collect
:-)
