[PATCH 01/28] drm/amd/display: Update IPS sequential_ono requirement checks

[Ray Wu]

From: Ovidiu Bunea <Ovidiu.Bunea@amd.com>

[why & how]
ASICs that require special RCG/PG programming are determined based
on hw_internal_rev. Update these checks to properly include all such
ASICs.

[PATCH 02/28] drm/amd/display: Refactoring DSC enum dsc_bits_per_comp.

[Ray Wu]

From: Bhuvanachandra Pinninti <bpinnint@amd.com>

[Why]
Previously the 'dsc_bits_per_comp' enumeration was defined in individual
.c files, making it unavailable for other files that may need it.

[How]
The 'dsc_bits_per_comp' enumeration has been relocated to a common header
file.

[PATCH 04/28] drm/amd/display: Always Scale Flag

[Ray Wu]

From: Jesse Agate <jesse.agate@amd.com>

[Why & How]
When always scale flag is set at the API level, the number of taps
should not be overridden to zero in the identity scaling ratio case,
and luma scale should not be set to bypass regardless of luma scale
ratio

[PATCH 06/28] drm/amd/display: Fix invalid context error in dml helper

[Ray Wu]

From: Roman Li <Roman.Li@amd.com>

[Why]
"BUG: sleeping function called from invalid context" error.
after:
"drm/amd/display: Protect FPU in dml2_validate()/dml21_validate()"

The populate_dml_plane_cfg_from_plane_state() uses the GFP_KERNEL flag
for memory allocation, which shouldn't be used in atomic contexts.

The allocation is needed only for using another helper function
get_scaler_data_for_plane().

[How]
Modify helpers to pass a pointer to scaler_data within existing context,
eliminating the need for dynamic memory allocation/deallocation
and copying.

Fixes: d1df16640462 ("drm/amd/display: Protect FPU in dml2_validate()/dml21_validate()")

[PATCH 07/28] drm/amd/display: Prepare for Fused I2C-over-AUX

[Ray Wu]

From: Dominik Kaszewski <dominik.kaszewski@amd.com>

[Why]
Passive DP-HDMI dongles use I2C-over-AUX protocol which is currently
not supported using HDCP Locality Check FW path.

[How]
Prepare code for switching to I2C-over-AUX protocol. Passive dongle
detection to be added in another commit.

[PATCH 09/28] drm/amd/display: allow dscclk disable

[Ray Wu]

From: Charlene Liu <Charlene.Liu@amd.com>

[why]
when dscclk rcg disabled from usr reg option,
dsc clock will remain enabled because driver was doing two things
both dscclk and dsc rcg in the same routine.

[PATCH 10/28] drm/amd/display: more liberal vmin/vmax update for freesync

[Ray Wu]

From: Aurabindo Pillai <aurabindo.pillai@amd.com>

[Why]
FAMS2 expects vmin/vmax to be updated in the case when freesync is
off, but supported. But we only update it when freesync is enabled.

[How]
Change the vsync handler such that dc_stream_adjust_vmin_vmax() its called
irrespective of whether freesync is enabled. If freesync is supported,
then there is no harm in updating vmin/vmax registers.

Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3546

[PATCH 11/28] drm/amd/display: disable DPP RCG before DPP CLK enable

[Ray Wu]

From: Charlene Liu <Charlene.Liu@amd.com>

[why]
DPP CLK enable needs to disable DPPCLK RCG first.
The DPPCLK_en in dccg should always be enabled when the corresponding
pipe is enabled.

[PATCH 18/28] drm/amd/display: Remove unnecessary DC_FP_START/DC_FP_END

[Ray Wu]

From: Alex Hung <alex.hung@amd.com>

[WHY & HOW]
Remove the unnecessary DC_FP_START/DC_FP_END pair to reduce time in
preempt_disable. It also fixes "BUG: sleeping function called from
invalid context" error messages because of calling kzalloc with
GFP_KERNEL which can sleep.

[PATCH 19/28] drm/amd/display: Call FP Protect Before Mode Programming/Mode Support

[Ray Wu]

From: Austin Zheng <Austin.Zheng@amd.com>

[Why]
Memory allocation occurs within dml21_validate() for adding phantom planes.
May cause kernel to be tainted due to usage of FP Start.

[How]
Move FP start from dml21_validate to before mode programming/mode support.
Calculations requiring floating point are all done within mode programming
or mode support.

[PATCH 21/28] drm/amd/display: Refactor SubVP cursor limiting logic

[Ray Wu]

From: Dillon Varone <dillon.varone@amd.com>

[WHY]
There are several gaps that can result in SubVP being enabled with
incompatible HW cursor sizes, and unjust restrictions to cursor size due
to wrong predictions on future usage of SubVP.

[HOW]
- remove "prediction" logic in favor of tagging based on previous SubVP
  usage
- block SubVP if current HW cursor settings are incompatible
- provide interface for DM to determine if HW cursor should be disabled
  due to an attempt to enable SubVP

[PATCH 22/28] drm/amd/display: Shift DMUB AUX reply command if necessary

[Ray Wu]

From: Wayne Lin <Wayne.Lin@amd.com>

[Why]
Defined value of dmub AUX reply command field get updated but didn't
adjust dm receiving side accordingly.

[How]
Check the received reply command value to see if it's updated version
or not. Adjust it if necessary.

[PATCH 24/28] drm/amd/display: Remove incorrect checking in dmub aux handler

[Ray Wu]

From: Wayne Lin <Wayne.Lin@amd.com>

[Why & How]
"Request length != reply length" is expected behavior defined in spec.
It's not an invalid reply. Besides, replied data handling logic is not
designed to be written in amdgpu_dm_process_dmub_aux_transfer_sync().
Remove the incorrectly handling section.

[Ray Wu]

From: Wayne Lin <Wayne.Lin@amd.com>

[Why]
We incorrectly ack all bytes get written when the reply actually is defer.
When it's defer, means sink is not ready for the request. We should
retry the request.

[How]
Only reply all data get written when receive I2C_ACK|AUX_ACK. Otherwise,
reply the number of actual written bytes received from the sink.
Add some messages to facilitate debugging as well.

Is this safe?  If this function uses FP or calls a function which uses
FP, removing these will lead to register corruption.

I checked dcn32_resource_construct again and I did not find any FP or 
functions uses FP, and Aurabindo helped double check.

I also checked other dnc*_resource_construct (like 321, 35, 351, 36) and 
they don't use DC_FP_START/DC_FP_END pair either.

So it should be safe to remove this pair.

RE: [PATCH 00/28] DC Patches May 05 2025

[Wheeler, Daniel]

[Public]

Hi all,

This week this patchset was tested on 4 systems, two dGPU and two APU based, and tested across multiple display and connection types.

APU
        * Single Display eDP -> 1080p 60hz, 2560x1600 120hz, 1920x1200 165hz
        * Single Display DP (SST DSC) -> 4k144hz, 4k240hz
        * Multi display -> eDP + DP/HDMI/USB-C -> 1080p 60hz eDP + 4k 144hz, 4k 240hz (Includes USB-C to DP/HDMI adapters)
        * Thunderbolt -> LG Ultrafine 5k
        * MST DSC -> Cable Matters 101075 (DP to 3x DP) with 3x 4k60hz displays, HP Hook G2 with 2x 4k60hz displays
        * USB 4 -> HP Hook G4, Lenovo Thunderbolt Dock, both with 2x 4k60hz DP and 1x 4k60hz HDMI displays
        * SST PCON -> Club3D CAC-1085 + 1x 4k 144hz, FRL3, at a max resolution supported by the dongle of 4k 120hz YUV420 12bpc.
        * MST PCON -> 1x 4k 144hz, FRL3, at a max resolution supported by the adapter of 4k 120hz RGB 8bpc.

DGPU
        * Single Display DP (SST DSC) -> 4k144hz, 4k240hz
        * Multiple Display DP -> 4k240hz + 4k144hz
        * MST (Startech MST14DP123DP [DP to 3x DP] and 2x 4k 60hz displays)
        * MST DSC (with Cable Matters 101075 [DP to 3x DP] with 3x 4k60hz displays)

The testing is a mix of automated and manual tests. Manual testing includes (but is not limited to)
        * Changing display configurations and settings
        * Video/Audio playback
        * Benchmark testing
        * Suspend/Resume testing
        * Feature testing (Freesync, HDCP, etc.)

Automated testing includes (but is not limited to)
        * Script testing (scripts to automate some of the manual checks)
        * IGT testing

The testing is mainly tested on the following displays, but occasionally there are tests with other displays
        * Samsung G8 Neo 4k240hz
        * Samsung QN55QN95B 4k 120hz
        * Acer XV322QKKV 4k144hz
        * HP U27 4k Wireless 4k60hz
        * LG 27UD58B 4k60hz
        * LG 32UN650WA 4k60hz
        * LG Ultrafine 5k 5k60hz
        * AU Optronics B140HAN01.1 1080p 60hz eDP
        * AU Optronics B160UAN01.J 1920x1200 165hz eDP
        * AU Optronics B160QAN02.L 2560x1600 120hz eDP

The patchset consists of the amd-staging-drm-next branch (Head commit - b5383f917c59e8a5e61f469bb41dc8c826258d92 -> drm/amdgpu/mes: remove more unused functions) with new patches added on top of it.

Tested on Ubuntu 24.04.1, on Wayland and X11, using KDE Plasma and Gnome.
