11964258fe drm/amdkfd: Get unique_id dynamically v2
Instead of caching the value during amdgpu_device_init, just call the
function directly. This avoids issues where the unique_id hasn't been
saved by the time that KFD's topology snapshot is done (e.g. Arcturus).

KFD's topology information from the amdgpu_device was initially cached
at KFD initialization due to amdkfd and amdgpu being separate modules.
Now that they are combined together, we can directly call the functions
that we need and avoid this unnecessary duplication and complexity.

As a side-effect of this change, we also remove unique_id=0 for CPUs,
which is obviously not unique.

v2: Drop previous patch printing unique_id in hex

0a52a6cacc drm/amdgpu: add wave limit functionality for gfx8,9
Wave limiting can be use to load balance high priority
compute jobs along with gfx jobs. When enabled, this will reserve
~75% of waves for compute jobs.

We do not need this from gfx10 onwards because >=gfx10 has
asynchronous compute tunneling to replace wave limit requirement.

For high priority compute to work properly we need to enable

6eed1f3fba drm/amd/display: Fix unused variable warning
[Why]
The dm struct is only being used if DCN config is defined and this
causes a unused variable warning if DCN option is not set.

[How]
Remove the compile flag so the variable is used (there also seems to be
a duplicate guard due to a bad rebase) so remove the outer guard to fix
the warning.

Fixes this warning
drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c: In function 'dm_set_vblank':
drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c:5380:33: warning: unused variable 'dm' [-Wunused-variable]

40d916a260 drm/amd/display: Reject too small viewport size when validating plane
[why]
Overlay won't move to a new positon if viewport size is smaller than
what can be handled. It'd either disappear or stay at the old
position. This condition is for example hit if overlay is moved too
much outside of left or top edge of the screen, but it applies to
any non-cursor plane type.

[how]
Reject this contidion at validation time. This gives the calling
level a chance to handle this gracefully and avoid inconsistent
behaivor.

e2dcd9b8b8 drm/amd/display: Better handling of dummy p-state table
[Why]
Some scenarios where we use a UCLK frequency in between dummy p-state table
entries result in a p-state hang, due to the table not having a close
enough match, so the default DPM0 latency is used, which can be too long to
support dummy p-state switching in these scenarios.

[How]
 - old: match if current freq is within +- margin of table entry
 - new: find largest table entry that is lower than current freq + margin
   - lower than DPM0 will still use DPM0

Maximum resolution is 1440*900 when connecting to FHD monitor via some DP-VGA

c64b0d6bb5 drm/amd/display: Decrement refcount of dc_sink before reassignment
[why]
An old dc_sink state is causing a memory leak because it is missing a
dc_sink_release before a new dc_sink is assigned back to
aconnector->dc_sink.

[how]
Decrement the dc_sink refcount before reassigning it to a new dc_sink.

a38b873f49 drm/amd/display: Fix CW4 programming for dmub30 cached inbox
[Why]
The conditions for whether we used cached vs non-cached inbox1 depend
on a version check that mismatches what the shared helpers in dmub20
implement.

[How]
Use the dmub_dcn20_use_cached_inbox check for dmub_dcn30 as well.

163e3bcbca drm/amd/display: fix initial bounding box values for dcn3.02
[Why]
Initial bounding box values are updated in dcn30_update_bw_bounding_box
 but they use dcn3_0_soc and dcn3_0_ip instead of dcn3_02_soc and
 dcn3_02_ip

[How]
Add dcn302_update_bw_bounding_box and
 dcn302_get_optimal_dcfclk_fclk_for_uclk so it uses
 dcn3_02_soc and dcn3_02_ip.
Use sr_exit_time_us, sr_enter_plus_exit_time_us,
 from dcn30 on dcn302 to fix flicker on eDP.
 Also use dram_clock_change_latency_us from dcn30.
