028a998c62 drm/amd/display: Defer LUT memory powerdown until LUT bypass latches
[WHY]
Blnd, 3dlut, and shaper LUT select registers are double buffered, however
their accompanying LUT memory shutdown registers are not. As a result,
shutting down LUT memory immediately after setting a block to bypass causes
corruption as bypass only happens at next Vupdate.

[HOW]
Re-enable mem low power for CM block
Force optimization on next flip and disable LUT memory during optimization
sequence if LUT select field is then set to bypass

if vsync is disabled and steady state is reached.

253a55918c drm/amd/display: Fix issue with dynamic bpp change for DCN3x
Why:
Screen sometimes would have artifacts or blink once at the time when bpp
is dynamically changed.

How:
1. Changed to update PPS infopacket in frame mode instead of immediate mode
   since other updates for bpp change are double-buffered.
2. Changed double-buffering enablement programming for DCN30 as advised by
ASIC team

0d4b4253ad drm/amd/display: Fix dynamic encoder reassignment
[Why]
Incorrect encoder assignments were being used while applying a new state
to hardware.

(1) When committing a new state to hardware requires resetting the
back-end, the encoder assignments of the current or old state should be
used when disabling the back-end; and the encoder assignments for the
next or new state should be used when re-enabling the back-end.

(2) Link training on hot plug could take over an encoder already in use
by another stream without first disabling it.

[How]

(1) Introduce a resource context 'link_enc_cfg_context' which includes:
- a mode to indicate when transitioning from current to next state.
- transient encoder assignments to use during this state transition.

Update the encoder configuration interface to respond to queries about
encoder assignment based on the mode of operation.

(2) Check if an encoder is already in use before attempting to perform
link training on hot plug.

b3492ed160 drm/amd/display: Fix concurrent dynamic encoder assignment
[Why]
Trying to enable multiple displays simultaneously exposed shortcomings
with the algorithm for dynamic link encoder assignment.

The main problems were:
- Assuming stream order remained constant across states would sometimes
lead to invalid DIG encoder assignment.
- Incorrect logic for deciding whether or not a DIG could support a
stream would also sometimes lead to invalid DIG encoder assignment.
- Changes in encoder assignment were wholesale while updating of the
pipe backend is incremental. This would lead to the hardware state not
matching the software state even with valid encoder assignments.

[How]

The following changes fix the identified problems.
- Use stream pointer rather than stream index to track streams across
states.
- Fix DIG compatibility check by examining the link signal type rather
than the stream signal type.
- Modify assignment algorithm to make incremental updates so software
and hardware states remain coherent.

Additionally:
- Add assertions and an encoder assignment validation function
link_enc_cfg_validate() to detect potential problems with encoder
assignment closer to their root cause.
- Reduce the frequency with which the assignment algorithm is executed.
It should not be necessary for fast state validation.

6566cae7ae drm/amd/display: fix odm scaling
There are two issues with scaling calculations, odm recout
calculation and matching viewport to actual recout.

This change fixes both issues. Odm recout calculation via
special casing and viewport matching issue by reworking
the viewport calcualtion to use scaling ratios and recout
to derrive the required offset and size.

3ca402375a drm/amd/display: Refactor and add visual confirm for HW Flip Queue
[Why]
Visual confirm will indicate if driver is programming
the surface address.
Refactor is required because much of the visual confirm
logic is buried deep in the mpcc files.
In addition, visual confirm is not updated during fast updates.

[How]
In order to have visual confirm for driver flips, visual confirm
needs to be updated on every frame, including fast updates.
Add a new hw sequencer interface update_visual_confirm_color,
and a new mpc function pointer set_bg_color.

[WHY]
There is a bug in HW that causes P-State to hang when DPG is enabled in
certain conditions.

[HOW]
The solution is to force MIN_TTU_VBLANK register to maximum value
whenever DPG has been enabled.
Make stream do a full update on test pattern change, so that the TTUs
get updated.
When DPG is enabled, update the ttu_regs.min_ttu_vblank field of each

4f8e37dbaf drm/amd/display: Support for DMUB AUX
[WHY]
To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes.

[HOW]
1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands
   to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd
   with DCN and sends reply back in an outbox1 message triggering an
   outbox1 interrupt to driver.
2) In existing driver implementation, AUX commands are processed
   synchronously by configuring DCN reg. But in DMUB AUX, driver sends an
   inbox1 message and waits for a conditional variable (CV) which will be
   signaled by outbox1 ISR.
3) As the driver holds dal and dc locks while waiting for CV, the outbox1
   ISR is registered with noMutexWait set to true, which allows ISR to run
   and signal CV. This sets a constraint on ISR to not modify variables
   such as dc, dmub, etc.
4) Created dmub_outbox.c with dmub_enable_outbox_notification() to enable
   outbox1 mailbox.
5) New mailbox address ranges allocated for outbox1 of size DMUB_RB_SIZE.
   Created dmub functions for Outbox1: dmub_dcn20_setup_out_mailbox(),
   dmub_dcn20_get_outbox1_wptr() and dmub_dcn20_set_outbox1_rptr().
6) Added functions dc_stat_get_dmub_notification() and
   dmub_srv_stat_get_notification() to retrieve Outbox1 message.
7) Currently, DMUB doesn't opens DDC in AUX mode before issuing AUX
   transaction. A workaround is added in dce_aux_transfer_dmub_raw() to
   open in DDC in AUX mode for every AUX transaction.
8) Added dc debug option enable_dmub_aux_for_legacy_ddc enable/disable
   DMUB AUX. This debug option is checked dce_aux_transfer_with_retries()
   to select the method to process AUX transactions.
