[PATCH 00/16] DC Patches August 18, 2023

[Wayne Lin]

This DC patchset brings improvements in multiple areas. In summary, we have:

- Ensure FS is enabled before sending request to DMUB for FS changes
- Add check for PMFW hard min request complete
- Save addr update in scratch before flip
- Fix static screen detection setting
- Write flip addr to scratch reg for subvp
- set minimum of VBlank_nom
- Correct unit conversion for vstartup
- Roll back unit correction
- Enable runtime register offset init for DCN32 DMUB
- Refactor edp power control
- PQ regamma end point
- PQ tail accuracy
- Blank phantom OTG before enabling
- Expose mall capability

[PATCH 02/16] drm/amd/display: Blank phantom OTG before enabling

[Wayne Lin]

From: Alvin Lee <alvin.lee2@amd.com>

[Why & How]
Before enabling the phantom OTG for an update we
must enable DPG to avoid underflow.

[PATCH 03/16] drm/amd/display: PQ tail accuracy

[Wayne Lin]

From: Krunoslav Kovac <krunoslav.kovac@amd.com>

[WHY & HOW]
HW LUTs changed slightly in DCN3: 256 base+slope pairs were replaced by
257 bases. Code was still calculating all 256 base+slope and then
creating 257th pt as last base + last slope.
This was done in wrong format, and then "fixed" it by making the last
two points the same thus making the last slope=0.
However, this also created some precision problems near the end that
are not visible but they do show up with capture cards.

Solution is to calculate 257 and remove deltas since we no longer have
those HW registers.

[PATCH 04/16] drm/amd/display: PQ regamma end point

[Wayne Lin]

From: Krunoslav Kovac <krunoslav.kovac@amd.com>

[WHY & HOW]
PQ has a fixed range of 0-10,000 nits.
Using 1=80 nits normalization, PQ should map to 1.0 for X=125.0
HW LUT used for interpolation does not have X=125 so it's interpolated.
However, we cap Y to 1 for all X>=125.

The closest larger HW point is 128.
What we want is Y(128) such that interpolation through 125 gives 1.0.
Such value is ~1.00256.
Another change is to hardcode PQ table, we pretty much always have 1=80
normalization so the table can be static.

[PATCH 05/16] drm/amd/display: Refactor edp power control

[Wayne Lin]

From: Ian Chen <ian.chen@amd.com>

[Why & How]
To organize the edp power control a bit:

1. add flag in dc_link to indicate dc to skip all implicit eDP power control.
2. add edp_set_panel_power link service for DM to call.

[PATCH 06/16] drm/amd/display: Enable runtime register offset init for DCN32 DMUB

[Wayne Lin]

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

[Why&How]
DMUB subsystem was continuing to use compile time offset calculation for
register access. Switch this to runtime calculation to stay consistent
with rest of DC code.

To enable this, an additional interface init_reg_offsets() are added to
DMUB's hw_funcs struct. Asics with runtime register offset calculation
enabled shall populate this hook with a fn pointer that will invoke the
necessary macros to calculate the offset.

[PATCH 07/16] drm/amd/display: Roll back unit correction

[Wayne Lin]

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

[why]
This Unit correction exposes a Replay corruption.

[how]
This reverts commit:
commit 7d3cedf18068 ("drm/amd/display: Correct unit conversion for vstartup")

Roll back unit conversion until Replay can fix their corruption.

[PATCH 08/16] drm/amd/display: Correct unit conversion for vstartup

[Wayne Lin]

From: Reza Amini <reza.amini@amd.com>

[why]
vstartup is calculated to be a large number. it works because
it is within vertical blank, but it reduces region of blank that
can be used for power gating.

[how]
Calculation needs to convert micro seconds to number of
vertical lines.

[PATCH 09/16] drm/amd/display: set minimum of VBlank_nom

[Wayne Lin]

From: ChunTao Tso <chuntao.tso@amd.com>

[Why]
If VBlank_nom is too small, it will cause
VStartUP_Start smaller than VBackPorch + VSync width which is an
invalid case for VStartUP_Start and where to send AS-SDP.

[How]
Setup a minimum value to VBlank_nom

[PATCH 10/16] drm/amd/display: Write flip addr to scratch reg for subvp

[Wayne Lin]

From: Alvin Lee <alvin.lee2@amd.com>

[Description]
SubVP needs to "calculate" the earliest in use META address
by using the current primary / meta addresses, but this leads
to a race condition where FW and driver can read/write the
address at the same time and intermittently produce inconsistent
address offsets. To mitigate this issue without locking (too slow),
save each surface flip addr into scratch registers and use this
to keep track of the earliest in use META addres.

[PATCH 11/16] drm/amd/display: fix static screen detection setting

[Wayne Lin]

From: SungHuai Wang <danny.wang@amd.com>

[WHY]
OTG_STATIC_SCREEN_EVENT_MASK is changed in DCN3,
but we still follow DCN2 to apply setting for
OTG_STATIC_SCREEN_EVENT_MASK.

[How]
Add new function to apply correct settings for DCN3 series.

[PATCH 13/16] drm/amd/display: add check for PMFW hard min request complete

[Wayne Lin]

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

[Why]
When we issue hard min request to PMFW, the ack back does not
guarantee the request has been fulfilled.

[How]
Add new PMFW message to check if the hard min request has been
completed. Returned bit mask indicates which clock requests are
completed. Check PMFW version before using message

[PATCH 14/16] drm/amd/display: ensure FS is enabled before sending request to DMUB for FS changes

[Wayne Lin]

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

[Why]
ignore_msa_timing_param indicates FS is capable but not necessarily enabled

[How]
add check for either allow_freesync or vrr_active_variable to confirm FS is enabled

RE: [PATCH 00/16] DC Patches August 18, 2023

[Wheeler, Daniel]

[Public]

Hi all,

This week this patchset was tested on the following systems:
        * Lenovo ThinkBook T13s Gen4 with AMD Ryzen 5 6600U
        * MSI Gaming X Trio RX 6800
        * Gigabyte Gaming OC RX 7900 XTX

These systems were tested on the following display/connection types:
        * eDP, (1080p 60hz [5650U]) (1920x1200 60hz [6600U]) (2560x1600 120hz[6600U])
        * VGA and DVI (1680x1050 60hz [DP to VGA/DVI, USB-C to VGA/DVI])
        * DP/HDMI/USB-C (1440p 170hz, 4k 60hz, 4k 144hz, 4k 240hz [Includes USB-C to DP/HDMI adapters])
        * Thunderbolt (LG Ultrafine 5k)
        * MST (Startech MST14DP123DP [DP to 3x DP] and 2x 4k 60Hz displays)
        * DSC (with Cable Matters 101075 [DP to 3x DP] with 3x 4k60 displays, and HP Hook G2 with 1 4k60 display)
        * USB 4 (Kensington SD5700T and 1x 4k 60Hz display)
        * PCON (Club3D CAC-1085 and 1x 4k 144Hz display [at 4k 120HZ, as that is the max the adapter supports])

The testing is a mix of automated and manual tests. Manual testing includes (but is not limited to):
        * Changing display configurations and settings
        * Benchmark testing
        * Feature testing (Freesync, etc.)

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

The patchset consists of the amd-staging-drm-next branch (Head commit - 06e1ec5a9a88 drm/amd/display: Promote DAL to 3.2.247) with new patches added on top of it.

Tested on Ubuntu 22.04.3, on Wayland and X11, using Gnome for both.
