99e7d65ccc drm/amdkfd: Allow CPU access for all VRAM BOs
The thunk needs to mmap all BOs for CPU access to allow the debugger to
access them. Invisible ones are mapped with PROT_NONE.

43a44c5322 drm/amdgpu: Return error if no RAS
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.

798c511548 drm/amdgpu: SRIOV flr_work should take write_lock
[Why]
If flr_work takes read_lock, then other threads who takes
read_lock can access hardware when host is doing vf flr.

[How]
flr_work should take write_lock to avoid this case.

757fa80f4e Tracing updates for 5.14:
- Added option for per CPU threads to the hwlat tracer
 
  - Have hwlat tracer handle hotplug CPUs
 
  - New tracer: osnoise, that detects latency caused by interrupts, softirqs
    and scheduling of other tasks.
 
  - Added timerlat tracer that creates a thread and measures in detail what
    sources of latency it has for wake ups.
 
  - Removed the "success" field of the sched_wakeup trace event.
    This has been hardcoded as "1" since 2015, no tooling should be looking
    at it now. If one exists, we can revert this commit, fix that tool and
    try to remove it again in the future.
 
  - tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids.
 
  - New boot command line option "tp_printk_stop", as tp_printk causes trace
    events to write to console. When user space starts, this can easily live
    lock the system. Having a boot option to stop just after boot up is
    useful to prevent that from happening.
 
  - Have ftrace_dump_on_oops boot command line option take numbers that match
    the numbers shown in /proc/sys/kernel/ftrace_dump_on_oops.
 
  - Bootconfig clean ups, fixes and enhancements.
 
  - New ktest script that tests bootconfig options.
 
  - Add tracepoint_probe_register_may_exist() to register a tracepoint
    without triggering a WARN*() if it already exists. BPF has a path from
    user space that can do this. All other paths are considered a bug.
 
  - Small clean ups and fixes

8dbe43e99f drm/amdgpu: Set ttm caching flags during bo allocation
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.

v2: rebase (Alex)

$ git grep -P '\b__assign_str\b' | wc -l

$ git grep -P '\b__assign_str\b.*;' | wc -l

Add semicolons to the __assign_str() uses without semicolon termination
and all the other uses without semicolon termination via additional defines
that are equivalent to __assign_str() with the eventual goal of removing
the semicolon from the __assign_str() macro definition.

754e9883d4 drm/amdgpu: correct clock gating settings on feature unsupported
Clock gating setting is still performed even when the corresponding
CG feature is not supported. And the tricky part is disablement is
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
is not supported.

Sometimes, DP receiver chip power-controlled externally by an
Embedded Controller could be treated and used as eDP,
if it drives mobile display. In this case,
we shouldn't be doing power-sequencing, hence we can skip
waiting for T7-ready and T9-ready."

[How]
Added a feature mask to enable eDP no power sequencing feature.

To enable this, set 0x10 flag in amdgpu.dcfeaturemask on

4c6a23188e drm/amdgpu: Call drm_framebuffer_init last for framebuffer init
Once drm_framebuffer_init has returned 0, the framebuffer is hooked up
to the reference counting machinery and can no longer be destroyed with

If drm_framebuffer_init returns 0 but its caller then returns non-0,
there will likely be memory corruption fireworks down the road.

eed75ce7c8 drm/amdgpu: fix amdgpu_preempt_mgr_new()
There is a reversed if statement in amdgpu_preempt_mgr_new() so it
always returns -ENOMEM.

24981fa336 drm/amdgpu: Call drm_framebuffer_init last for framebuffer init
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:

376002f4b0 drm/amd/amdgpu: Use IP discovery data to determine VCN enablement instead of MMSCH
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.

5fd953a3f6 drm/amd/display: Add Freesync video documentation
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.

the non-SR-IOV code below it already handles this properly.
