674e78acae drm/amd/display: Add fast path for cursor plane updates
[Why]
Legacy cursor plane updates from drm helpers go through the full
atomic codepath. A high volume of cursor updates through this slow
code path can cause subsequent page-flips to skip vblank intervals
since each individual update is slow.

This problem is particularly noticeable for the compton compositor.

[How]
A fast path for cursor plane updates is added by using DRM asynchronous
commit support provided by async_check and async_update. These don't do
a full state/flip_done dependency stall and they don't block other
commit work.

However, DC still expects itself to be single-threaded for anything
that can issue register writes. Screen corruption or hangs can occur
if write sequences overlap. Every call that potentially perform
register writes needs to be guarded for asynchronous updates to work.
The dc_lock mutex was added for this.

922454c2e7 drm/amd/display: Fix duplicating scaling/underscan connector state
[Why]
These properties aren't being carried over when the atomic state.
This tricks atomic check and commit tail into performing underscan
and scaling operations when they aren't needed.

With the patch that forced scaling/RMX_ASPECT on by default this
results in many unnecessary surface updates and hangs under certain
conditions.

[How]
Duplicate the properties.

65276f2beb drm/amd/display: Fix unintialized max_bpc state values
[Why]
If the "max bpc" isn't explicitly set in the atomic state then it
have a value of 0. This has the correct behavior of limiting a panel
to 8bpc in the case where the panel supports 8bpc. In the case of eDP
panels this isn't a true assumption - there are panels that can only
do 6bpc.

Banding occurs for these displays.

[How]
Initialize the max_bpc when the connector resets to 8bpc. Also carry
over the value when the state is duplicated.

28c5946930 Revert "drm/amd/display: Set RMX_ASPECT as default"
This reverts commit 91b66c47ba.

Forcing RMX_ASPECT as default uses the preferred/native mode's timings
for any mode the user selects and scales the image. This provides a
a consistently nicer result in the case where the selected mode's
refresh rate matches the native mode's refresh but this isn't always
the case.

For example, if the monitor is 1080p@144Hz and the preferred mode is
60Hz then even if the user selects 1080p@144Hz as their selected mode
they'll get 1080p@60Hz.

9ed9203c3e drm/amd/powerplay: rv dal-pplib interface refactor powerplay part
[WHY] clarify dal input parameters to pplib interface, remove
un-used parameters. dal knows exactly which parameters needed
and their effects at pplib and smu sides.

current dal sequence for dcn1_update_clock to pplib:

1.smu10_display_clock_voltage_request for dcefclk
2.smu10_display_clock_voltage_request for fclk
3.phm_store_dal_configuration_data {
  set_min_deep_sleep_dcfclk
  set_active_display_count
  store_cc6_data --- this data never be referenced

new sequence will be:

1. set_display_count  --- need add new pplib interface
2. set_min_deep_sleep_dcfclk -- new pplib interface
3. set_hard_min_dcfclk_by_freq
4. set_hard_min_fclk_by_freq

after this code refactor, smu10_display_clock_voltage_request,
phm_store_dal_configuration_data will not be needed for rv.

[HOW] step 1: add new functions at pplib interface
      step 2: add new functions at amdgpu dm and dc

1db8c142b6 drm/scheduler: Add drm_sched_suspend/resume_timeout()
This patch adds two new functions to help client drivers suspend and
resume the scheduler job timeout. This can be useful in cases where the
hardware has preemption support enabled. Using this, it is possible to have
the timeout active only for the ring which is active on the ringbuffer.
This patch also makes the job_list_lock IRQ safe.

9afd07566b drm/scheduler: Set sched->thread to NULL on failure
In cases where the scheduler instance is used as a base object of another
driver object, it's not clear if the driver can call scheduler cleanup on the
fail path. So, Set the sched->thread to NULL, so that the driver can safely
call drm_sched_fini() during cleanup.

0cf5eb76e2 drm/amd/display: Add tracing to dc
[Why]
Tracing is a useful and cheap debug functionality

[How]
This creates a new trace system amdgpu_dm, currently with
three trace events

amdgpu_dc_rreg and amdgpu_dc_wreg report the address and value
of any dc register reads and writes

amdgpu_dc_performance requires at least one of those two to be
enabled.  It counts the register reads and writes since the
last entry

This reverts commit 9a09a42369.

The whole interface isn't thought through. Since this function can't
fail we actually can't allocate an object to store the sync point.

Sorry, I should have taken the lead on this from the very beginning and
reviewed it more thoughtfully. Going to propose a new interface as a
follow up change.
