Improve DDX driver xf86-video-amdgpu

[reaperx7]

Since the project is getting caught up, and everything has been forked properly, we do need people to look at drivers:

amdgpu
intel

to see what all can be effectively brought up to date with modern hardware detection and what features can be used and preset in xorg.conf. Reliance on the modesetting is fine, but having a suitable fully featured DDX driver would be beneficial regardless.

amdgpu, when loaded, still doesn't allow usage of radv and zink as part of mesa. It also might lack RX 7000 and 9000 detection systems.

intel, I believe, might need updates for Xe, Alchemist, and Battlemage video chipsets.

xf86-video-intel if that's what you mean effectively got abandoned for anything newer than Skylake/Kabylake iGPUs, for newer stuff (and really even for whatever intel does support) you're supposed to use modesetting (though I myself don't because it doesn't really handle some common usecases all that well, apparently that was an issue for wayland at some point too but can confirm that at least Sway and Plasma Wayland do it fine now).

Looking into fixing whatever the heck modesetting gets tripped up on would probably be more worthwhile, if this fork's intent is to make X great again (as questionable sounding as that is) then that sounds like a somewhat important issue to fix here.

(full disclosure: haven't messed around with running xlibre myself yet but I don't see any reason why this would be fixed by now, so this still stands probably)

It would be helpful to find a way to get vsync controls added to the xorg.conf for modesetting.

Ideas:

Option "vsync_type" "string"

String options include:

"locked" - vsync is set to monitor's EDID refresh rate.
"variable" - vsync is allowed to adjust automatically for g-sync/freesync
"disabled" - vsync is off. monitor either can self manage if capable, or video is allowed to render as fast as possible (useful for benchmarks).

Modesetting options are very basic and lackluster compared to the carss they support.

The program adriconf has some options but seem to be only aimed at OpenGL settings, not DDX or Vulkan.

I'm on an Intel 8 or 9th gen celeron myself and modesetting is still borked for me, fast transitions basically show heavy compression artifacts and its overall much slower at switching resolutions. So I'm basically stuck to the Intel driver currently.

@reaperx7 What was a good self-explanatory title for this issue? Something like:
"Modernize amd and intel video drivers"?

[reaperx7]

Yes possibly.

The xf86-video-amdgpu driver might need updates for the following:

• [ ] Add support for Radeon RX 7000 and 9000 series GPUs and other Radeon iGPUs/APUs.
• [ ] Add support for usage of mesa-radv and mesa-zink via vulkan and opengl driver selection scripts and commands. Modesetting allows this.

As far as xf86-video-intel driver, apparently the driver has been relegated to legacy iGPUs mainly and not Xe (DG1/2/3) and later iGPUs.

Please file those driver specific issues in the corresponding driver repo.
Thanks.
