In amdgpu_ras_query_error_count() return an error
if the device doesn't support RAS. This prevents
that function from having to always set the values
of the integer pointers (if set), and thus
prevents function side effects--always to have to
set values of integers if integer pointers set,
regardless of whether RAS is supported or
not--with this change this side effect is
mitigated.
Also, if no pointers are set, don't count, since
we've no way of reporting the counts.
Also, give this function a kernel-doc.

The ttm caching flags (ttm_cached, ttm_write_combined etc) are
used to determine a buffer object's mapping attributes in both
CPU page table and GPU page table (when that buffer is also
accessed by GPU). Currently the ttm caching flags are set in
function amdgpu_ttm_io_mem_reserve which is called during
DRM_AMDGPU_GEM_MMAP ioctl. This has a problem since the GPU
mapping of the buffer object (ioctl DRM_AMDGPU_GEM_VA) can
happen earlier than the mmap time, thus the GPU page table
update code can't pick up the right ttm caching flags to
decide the right GPU page table attributes.
This patch moves the ttm caching flags setting to function
amdgpu_vram_mgr_new - this function is called during the
first step of a buffer object create (eg, DRM_AMDGPU_GEM_CREATE)
so the later both CPU and GPU mapping function calls will
pick up this flag for CPU/GPU page table set up.

Clock gating setting is still performed even when the corresponding

actually performed no matter for enablement or disablement request.
That seems not logically right.
Considering HW should already properly take care of the CG state, we
will just skip the corresponding clock gating setting when the feature

Once drm_framebuffer_init has returned 0, the framebuffer is hooked up
to the reference counting machinery and can no longer be destroyed with
a simple kfree. Therefore, it must be called last.
If drm_framebuffer_init returns 0 but its caller then returns non-0,
there will likely be memory corruption fireworks down the road.

There is a reversed if statement in amdgpu_preempt_mgr_new() so it
always returns -ENOMEM.

Once drm_framebuffer_init has returned 0, the framebuffer is hooked up
to the reference counting machinery and can no longer be destroyed with
a simple kfree. Therefore, it must be called last.
If drm_framebuffer_init returns 0 but its caller then returns non-0,
there will likely be memory corruption fireworks down the road.
The following lead me to this fix:

In the past, we use MMSCH to determine whether a VCN is enabled or not.
This is not reliable since after a FLR, MMSCH may report junk data.
It is better to use IP discovery data.

Recently, we added support for an experimental feature named Freesync
video; for more details on that, refer to:
commit 6f59f229f8 ("drm/amd/display: Skip modeset for front porch change")
commit d10cd527f5 ("drm/amd/display: Add freesync video modes based on preferred modes")
commit 0eb1af2e82 ("drm/amd/display: Add module parameter for freesync video mode")
Nevertheless, we did not document it in detail in our driver. This
commit introduces a kernel-doc and expands the module parameter
description.

Probably a rebase leftover. This doesn't apply to SR-IOV, and
the non-SR-IOV code below it already handles this properly.
