[PATCH 02/15] drm/amd/display: Reset cached PSR parameters after hibernate

[Stylon Wang]

From: Evgenii Krasnikov <Evgenii.Krasnikov@amd.com>

[WHY]
After hibernate system might be using old invalid psr_power_opt and
psr_allow_active that never get reset

[HOW]
Reset cached Panel Self Refresh parameters when PSR is first configured
for eDP in dc_link_setup_psr.

[PATCH 05/15] drm/amd/display: do not calculate DP2.0 SST payload when link is off

[Stylon Wang]

From: Wenjing Liu <wenjing.liu@amd.com>

[Why & How]
There is a chance where the RX issues HPD deassert in the
middle of link training, this will cause our logic to
abort link training and turn off link. However our payload
allocation logic needs to use current link settings to
determine average time slot per MTP. This will need to
use current link bandwidth as divider. This causes divide
by zero error occasionally. The fix is to skip DP2.0 payload
allocation logic if current link is not in 128b/132b mode.

[Stylon Wang]

From: Josip Pavic <Josip.Pavic@amd.com>

[Why]
Waiting for the vlbank every time a global sync update is requested,
including during full update flips, results in a stutter.

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

[Why & How]
CONFIG_DRM_AMD_DC_DCN is used by pass the compilation failures, but DC
code should be OS-agnostic.

This patch fixes it by removing unnecessasry CONFIG_DRM_AMD_DC_DCN
in dc and dc/core directories.

[PATCH 08/15] drm/amd/display: remove redundant CONFIG_DRM_AMD_DC_DCN in dce

[Stylon Wang]

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

[Why & How]
CONFIG_DRM_AMD_DC_DCN is used by pass the compilation failures, but DC
code should be OS-agnostic.

This patch fixes it by removing unnecessasry CONFIG_DRM_AMD_DC_DCN
in dce directory.

[PATCH 09/15] drm/amd/display: remove redundant CONFIG_DRM_AMD_DC_DCN in gpio

[Stylon Wang]

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

[Why & How]
CONFIG_DRM_AMD_DC_DCN is used by pass the compilation failures, but DC
code should be OS-agnostic.

This patch fixes it by removing unnecessasry CONFIG_DRM_AMD_DC_DCN
in gpio directory.

[PATCH 10/15] drm/amd/display: remove redundant CONFIG_DRM_AMD_DC_DCN in irq

[Stylon Wang]

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

[Why & How]
CONFIG_DRM_AMD_DC_DCN is used by pass the compilation failures, but DC
code should be OS-agnostic.

This patch fixes it by removing unnecessasry CONFIG_DRM_AMD_DC_DCN
in irq directory.

[PATCH 13/15] drm/amd/display: remove unnecessary else by CONFIG_DRM_AMD_DC_DCN

[Stylon Wang]

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

[Why & How]
CONFIG_DRM_AMD_DC_DCN is used by pass the compilation failures, but DC
code should be OS-agnostic.

This patch fixes it by removing unnecessasry CONFIG_DRM_AMD_DC_DCN
guards for #if-#else clause.

[PATCH 14/15] Revert "drm/amd/display: Fix DCN3 B0 DP Alt Mapping"

[Stylon Wang]

This reverts commit 4b7786d87fb3adf3e534c4f1e4f824d8700b786b.

Commit 4b7786d87fb3 "drm/amd/display: Fix DCN3 B0 DP Alt
Mapping" is causing 2nd USB-C display not lighting up.
Phy id remapping is done differently than is assumed in this
patch.

I presume the driver still builds properly on configs where
CONFIG_DRM_AMD_DC_DCN is not set?  E.g., platforms without floating
point for example?

Hi Alex,

This is part of our effort to isolate FPU code inside DML (right now, we 
are only missing DCN30); since we are really close to that, many of 
these guards become useless. All of these patches were tested in our CI 
against:

1. x86 with DCN
2. x86 without DCN
3. Clang
4. make allmodconfig

Additionally, I think that Alex Hung also checked the compilation with 
PowerPC.

Thanks
Siqueira

Hi Alex,

This is part of our effort to isolate FPU code inside DML (right now, we 
are only missing DCN30); since we are really close to that, many of 
these guards become useless. All of these patches were tested in our CI 
against:

1. x86 with DCN
2. x86 without DCN
3. Clang
4. make allmodconfig

Additionally, I think that Alex Hung also checked the compilation with 
PowerPC.

Thanks
Siqueira

RE: [PATCH 07/15] drm/amd/display: remove redundant CONFIG_DRM_AMD_DC_DCN in dc

[VURDIGERENATARAJ, CHANDAN]

Hi,

Changes are not needed in " drivers/gpu/drm/amd/display/Kconfig" ??
Also, is this change validated on Chrome?

BR,
Chandan V N

Re: [PATCH 07/15] drm/amd/display: remove redundant CONFIG_DRM_AMD_DC_DCN in dc

I don't think so, unless I'm missing something. We are not dropping the 
CONFIG_DRM_AMD_DC_DCN config; we are just removing it from some places 
that we don't need anymore. Do you have a specific concern?

> Also, is this change validated on Chrome?

I don't see any good reason why ChromeOS will not work with that; we are 
not sending this change to the stable kernel since it depends on our FPU 
code as well.

Daniel tested it on ChromeOS (amd-staging-drm-next); he will probably 
send his test result as a reply to the cover letter. Afik, everything is 
alright.

The community dropped support for ARM from RDNA1 (and above) a few years 
ago because of how we were handling the FPU code on the display side. 
However, we have been working on that for a couple of months; we are 
close to completing this work and re-enabling ARM + DCN soon.

Thanks
Siqueira

I am curious, what this means exactly? You clone the Ubuntu Linux 5.16 
kernel source, and then apply your patches on top? (Do they even apply?)

The same for Chrome OS. Do you use Chrome OS Flex [1] with the systems 
you listed? If not, what Google Chromebooks/-boxes did you test with? 
The Linux kernel version is also tied for a device and Chrome OS 
release. Please mention those too.

Is it documented somewhere, what tests you run exactly?


Kind regards,

Paul

All of these "promotion" patches are tested by using 
amd-staging-drm-next. In a few words:

1. We get the latest code from amd-staging-drm-next;
2. We apply these weekly promotion patches on top of it;
3. We compile, run unit tests, and run many manual tests (Daniel does that).

If everything is alright with Daniel's tests, we feel confident to merge 
these series on top amd-staging-drm-next (we are basically trying to 
avoid regressions here).

Anyway, maybe we can rephrase:

  Tested on Ubuntu 22.04 with Kernel Version 5.16, and ChromeOS

to

  Tested on Ubuntu 22.04 and ChromeOS with amd-staging-drm-next + 
promotion patches.

We run IGT tests, some scripts that validate some specific areas, and 
Daniel has an extensive set of manual tests.

Yes, that’d be great. Maybe even reference the commit hash from the 
commit on top of *amd-staging-drm-next*.

As written, the used Chrome OS version (and devices) would be helpful too.

RE: How are the DC patches tested?

[Wheeler, Daniel]

[Public]

Hi Paul,

I've made some edits to my cover letter to hopefully make it clearer with what is being done.




		Hi all,
 
		This week this patchset was tested on the following systems:
 
		HP Envy 360, with Ryzen 5 4500U
		Lenovo Thinkpad T14s Gen2, with AMD Ryzen 5 5650U 
		Sapphire Pulse RX5700XT 
		Reference AMD RX6800
		Engineering board with Ryzen 9 5900H

		These systems were tested on the following display types: 
		eDP, (1080p 60hz [4500U, 5650U, 5900H])
		VGA and DVI (1680x1050 60HZ [DP to VGA/DVI, USB-C to DVI/VGA])
		DP/HDMI/USB-C (1440p 170hz, 4k 60hz, 4k 144hz [Includes USB-C to DP/HDMI adapters])

		MST tested with Startech MST14DP123DP and 2x 4k 60Hz displays
		DSC tested with Cable Matters 101075 (DP to 3x DP), and 201375 (USB-C to 3x DP) with 3x 4k60 displays
 
		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 most recent amd-staging-drm-next branch with a selection of patches added on top of it. This goes for both Ubuntu testing and Chrome 		OS testing.

		Tested on Ubuntu 22.04 and Chrome OS

Please mention the commit hash of the commit at the top of 
amd-staging-drm-next.

I still do not see the Chrome OS version and devices listed. I think, 
that information would be valuable.
