[PATCH 01/10] drm/amd/display: temp w/a for dGPU to enter idle optimizations

[Wayne Lin]

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

[Why&How]
vblank immediate disable currently does not work for all asics. On
DCN401, the vblank interrupts never stop coming, and hence we never
get a chance to trigger idle optimizations.

Add a workaround to enable immediate disable only on APUs for now. This
adds a 2-frame delay for triggering idle optimization, which is a
negligible overhead.

Fixes: db11e20a1144 ("drm/amd/display: use a more lax vblank enable policy for older ASICs")
Fixes: 6dfb3a42a914 ("drm/amd/display: use a more lax vblank enable policy for DCN35+")

Considering the regression raised [1] is on an APU too I wonder if this 
is really the best workaround to approach to this issue.

Hi Mario,

Hamza is working on the reported issue and appears to be due to a different root cause. Hence, we're expecting that the fix for that issue is likely going to be different, with what we know so far. While that issue is being debugged, this patch will allow us to have better idle power consumption on dGPUs

Jay

[PATCH 02/10] drm/amd/display: w/a to program DISPCLK_R_GATE_DISABLE DCN35

[Wayne Lin]

From: Yihan Zhu <Yihan.Zhu@amd.com>

[WHY & HOW]
Cursor corruption observed on USBC display with specific system setup with a
reboot. Cursor memory might still in the lightsleep state due to voltage
issue, we need program DISPCLK_R_GATE_DISABLE to avoid this issue only on
DCN35.

[PATCH 05/10] drm/amd/display: temp w/a for DP Link Layer compliance

[Wayne Lin]

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

[Why&How]
Disabling P-State support on full updates for DCN401 results in
introducing additional communication with SMU. A UCLK hard min message
to SMU takes 4 seconds to go through, which was due to DCN not allowing
pstate switch, which was caused by incorrect value for TTU watermark
before blanking the HUBP prior to DPG on for servicing the test request.

Fix the issue temporarily by disallowing pstate changes for compliance
test while test request handler is reworked for a proper fix.

Fixes: 67ea53a4bd9d ("drm/amd/display: Disable DCN401 UCLK P-State support on full updates")

[PATCH 06/10] drm/amd/display: Recalculate SubVP Phantom VBlank End in dml21

[Wayne Lin]

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

[WHY]
The phantom stream timing is copied from the main stream as most
parameters are identical, however some need to be recalculated.
Currently VBlank End is not recalculated and copied from the main
incorrectly.

[HOW]
Recalculate VBlank End for phantom stream timing.

[PATCH 08/10] drm/amd/display: update fullscreen status to SPL

[Wayne Lin]

From: Samson Tam <Samson.Tam@amd.com>

[Why]
Current fullscreen check in SPL using dm_helpers is out-of-sync
with dc state. This causes an issue during minimal transition
where we pick an invalid intermediate state because the pre and
post fullscreen status are different.

[How]
Add sharpening_required flag to dc_stream_state. Use this flag to
indicate if we are in fullscreen or not. Propagate flag to SPL for
fullscreen status. Remove workaround in DML

RE: [PATCH 00/10] DC Patches October 14, 2024

[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 -> 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
        * DSC -> Cable Matters 101075 (DP to 3x DP) with 3x 4k60hz displays, HP Hook G2 with 3x 4k60hz displays (2x DP, 1x USB-C)
        * USB 4 -> HP Hook G4, Lenovo Thunderbolt Dock, both with 2x 4k60hz DP and 1x 4k60hz HDMI displays
        * PCON -> Club3D CAC-1085 + 1x 4k 144hz

DGPU
        * Single Display DP -> 4k144hz, 4k240hz
        * Multiple Display DP -> 4k240hz + 4k144hz
        * MST (Startech MST14DP123DP [DP to 3x DP] and 2x 4k 60hz displays)
        * 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 - 3631f572ee38bed4c3d0a9003570c63eaa9fd4e3 -> drm/amdgpu/swsmu: add automatic parameter to set_soft_freq_range) with new patches added on top of it.

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