f6e09701c3 drm/amd/display: Add check for granularity in dml ceil/floor helpers
[Why]
Wrapper functions for dcn_bw_ceil2() and dcn_bw_floor2()
should check for granularity is non zero to avoid assert and
divide-by-zero error in dcn_bw_ functions.

[How]
Add check for granularity 0.

79a57f9479 drm/amd/display: Add 6bpc RGB case for dcn32 output bpp calculations
[Why]
Current DCN32 calculation doesn't consider RGB 6bpc for the DP case.
This results in an invalid output bpp being calculated when DSC is not
enabled in the configuration, failing the mode validation.

[How]
Add special case to handle 6bpc RGB in the output bpp calculation.

d7879340e9 drm/amd/display: Disable replay and psr while VRR is enabled
[Why]
Replay and PSR will cause some video corruption while VRR is enabled.

[How]
1. Disable the Replay and PSR while VRR is enabled.
2. Change the amdgpu_dm_crtc_vrr_active() parameter to const.
   Because the function will only read data from dm_crtc_state.

f765e7ce04 drm/amd/display: Fix PSR-SU not support but still call the amdgpu_dm_psr_enable
[Why]
The enum DC_PSR_VERSION_SU_1 of psr_version is 1 and
DC_PSR_VERSION_UNSUPPORTED is 0xFFFFFFFF.

The original code may has chance trigger the amdgpu_dm_psr_enable()
while psr version is set to DC_PSR_VERSION_UNSUPPORTED.

[How]
Modify the condition to psr->psr_version == DC_PSR_VERSION_SU_1

1619d4168b drm/amd/display: Add HBlank reduction DPCD write to DPMS sequence
[Why]
Certain small HBlank timings may not have a large enough HBlank to
support audio when low bpp DSC is enabled. HBlank expansion by the
source can solve this problem, but requires the branch/sink to support
HBlank reduction.

[How]
Update DPMS sequence to call DM to perform DPCD write to enable HBlank
reduction on the branch/sink. Add stub in dm_helpers to be implemented
later.

787e7be0c9 drm/amd/display: Optimize cursor position updates
[why]
Updating the cursor enablement register can be a slow operation and accumulates
when high polling rate cursors cause frequent updates asynchronously to the
cursor position.

[how]
Since the cursor enable bit is cached there is no need to update the
enablement register if there is no change to it.  This removes the
read-modify-write from the cursor position programming path in HUBP and
DPP, leaving only the register writes.

c7c703e433 drm/amd/display: Ensure correct GFX tiling info passed to DML
[Why]
To ensure DML validation receives the correct tiling information,
such as swizzle mode or array mode, based on the active GFX format

[How]
- For new GFX format passed swizzle_mode to DML.
- For legacy GFX format passed array_mode to DML.
- Dynamically determined the appropriate tiling info based on the
  active GFX format.

[Description]
This commit ensures that the correct GFX tiling information is passed
to DML. Depending on the active GFX format, the appropriate tiling info
is passed to DML. This change accommodates the different GFX formats
supported by latest platforms, ensuring compatibility and proper
DML validation.

080950cbdd drm/amd/display: Update dc_tiling_info union to structure
[WHY]
The `dc_tiling_info` union previously did not have a field to
specify the active GFX format, assuming only one format would
be used per DCN version. from DCN4+, support for switching
between different GFX formats is introduced, requiring a way
to track which format is currently in use.

[HOW]
Updated the `dc_tiling_info` union to include a new field that
explicitly indicates the currently used GFX format.
This allows the system to determine the active GFX format
and take the correct programming path accordingly.

[Description]
The union `dc_tiling_info` has been updated to support multiple
GFX formats by adding a new field for identifying the active format.
This update ensures that the correct programming path is followed
based on the selected format. All references to `dc_tiling_info`
in the codebase have been updated to reflect the new structure.

44063dbcdb drm/amd/display: have pretrain for dpia
[WHY]
We like to have pretrain for dpia link so that dp and dp tunneling
have aligned behavior. The Main difficult for dpia pretrain is that
encoder can not get corresponded dpia port when link detection
in current implementation.

[HOW]
1. create enable/disable dpia output functions for dcn35 encoder
and have dpia_id and other necessary info as inputs.
2. dcn35 dpia use the new functions to enable/disable output.
3. have a option to enable/disable the change.

ab75a0d2e0 drm/amd/display: fix divide error in DM plane scale calcs
dm_get_plane_scale doesn't take into account plane scaled size equal to
zero, leading to a kernel oops due to division by zero. Fix by setting
out-scale size as zero when the dst size is zero, similar to what is
done by drm_calc_scale(). This issue started with the introduction of
cursor ovelay mode that uses this function to assess cursor mode changes
via dm_crtc_get_cursor_mode() before checking plane state.

1c86c81a86 drm/amd/display: fix page fault due to max surface definition mismatch
DC driver is using two different values to define the maximum number of
surfaces: MAX_SURFACES and MAX_SURFACE_NUM. Consolidate MAX_SURFACES as
the unique definition for surface updates across DC.

It fixes page fault faced by Cosmic users on AMD display versions that
support two overlay planes, since the introduction of cursor overlay
mode.

83626efdce drm/amd/display: Disable MPC rate control on ODM pipe update
[Why]
Seamless boot skips MPC init for the active pipe, resulting in stale MPC
rate control state being retained. This will cause issues since other
logic assumes it is disabled (as DCN30 and newer does not need it).

[How]
Disable MPC rate control on ODM pipe update to cover the seamless boot
case.

04d6273fae Revert "drm/amd/display: Fix green screen issue after suspend"
This reverts commit 87b7ebc2e1.

A long time ago, we had an issue with the Raven system when it was
connected to two displays: one with DP and another with HDMI. After the
system woke up from suspension, we saw a solid green screen caused by an
underflow generated by bad DCC metadata. To workaround this issue, the
'commit 87b7ebc2e1 ("drm/amd/display: Fix green screen issue after
suspend")' was introduced to disable the DCC for a few frames after in
the resume phase. However, in hindsight, this solution was probably a
workaround at the kernel level for some issues from another part
(probably other driver components or user space). After applying this
patch and trying to reproduce the green issue in a similar hardware
system but using the latest kernel and userspace, we cannot see the
issue, which makes this workaround obsolete and creates extra
unnecessary complexity to the code; for all of this reason, this commit
reverts the original change.

1b0cbcf888 drm/amd/display: Fix uninitialized variables in amdgpu_dm_debugfs
[WHAT]
Some fields in struct dc_link_settings and link_training_settings are
not initialized and using them can cause unexpected results.

[HOW]
Initialize struct dc_link_settings and link_training_settings to zero.

57a793a74f drm/amd/display: Apply (some) policy for DML2 formulation on DCN35/DCN351
[Why]
Dropping the entirety of dml2_policy_build_synthetic_soc_states exposes
an issue for states that cannot be filled via bbox_overrides and rely on
the default parameters that may or may not be present depending on the
DM.

For amdgpu_dm this results in missing parameters for most of the struct
in higher states:

- sr_exit_time_us
- sr_enter_plus_exit_time_us
- sr_exit_z8_time_us
- sr_enter_plus_exit_z8_time_us
- urgent_latency_pixel_data_only_us
- urgent_latency_pixel_mixed_with_vm_data_us
- urgent_latency_vm_data_only_us
- dram_clock_change_latency_us
- fclk_change_latency_us
- usr_retraining_latency_us
- writeback_latency_us
- urgent_latency_adjustment_fabric_clock_component_us
- urgent_latency_adjustment_fabric_clock_reference_mhz
- dscclk_mhz
- phyclk_mhz
- phyclk_d18_mhz
- phyclk_d32_mhz
- use_ideal_dram_bw_strobe

[How]
Copy from the first state, applying a minimal policy to set max clocks
for SOC independent values.

Then copy the SOC dependent ones from the states modified by
bbox_overrides.

e56ad45e99 drm/amd/display: Fix Mode Cutoff in DSC Passthrough to DP2.1 Monitor
Source --> DP2.1 MST hub --> DP1.4/2.1 monitor

When change from DP1.4 to DP2.1 from monitor manual, modes higher than
4k120 are all cutoff by mode validation. Switch back to DP1.4 gets all
the modes up to 4k240 available to be enabled by dsc passthrough.

[why]
Compared to DP1.4 link from hub to monitor, DP2.1 link has larger
full_pbn value that causes overflow in the process of doing conversion
from pbn to kbps.

[how]
Change the data type accordingly to fit into the data limit during
conversion calculation.
