[ Upstream commit 0021d70a0654e668d457758110abec33dfbd3ba5 ]

I think this was an abstraction back from when
kfd supported both radeon and amdgpu.  Since we just
support amdgpu now, there is no more need for this and
we can use the amdgpu structures directly.

This also avoids having the kfd_cu_info structures on
the stack when inlining which can blow up the stack.

[ Upstream commit a93b1020eb9386d7da11608477121b10079c076a ]

Since 2320c9e6a768 ("drm/sched: memset() 'job' in drm_sched_job_init()")
accessing job-&gt;base.sched can produce unexpected results as the initialisation
of (*job)-&gt;base.sched done in amdgpu_job_alloc is overwritten by the
memset.

This commit fixes an issue when a CS would fail validation and would
be rejected after job-&gt;num_ibs is incremented. In this case,
amdgpu_ib_free(ring-&gt;adev, ...) will be called, which would crash the
machine because the ring value is bogus.

To fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this
because the device is actually not used in this function.

The next commit will remove the ring argument completely.

commit 73dae652dcac776296890da215ee7dec357a1032 upstream.

Split resume into a 3rd step to handle displays when DCC is
enabled on DCN 4.0.1.  Move display after the buffer funcs
have been re-enabled so that the GPU will do the move and
properly set the DCC metadata for DCN.

v2: fix fence irq resume ordering

[ Upstream commit 928cd772e18ffbd7723cb2361db4a8ccf2222235 ]

It is not necessarily corrupted. When there is RAS fatal error, device
memory access is blocked. Hence vcpu bo cannot be saved to system memory
as in a regular suspend sequence before going for reset. In other full
device reset cases, that gets saved and restored during resume.

v2: Remove redundant code like vcn_v4_0 did
