With many Linux desktops now running Wayland quite nicely, it seems it's time to keep pushing ahead. AMD have revealed what they call the AMDGPU Composition Stack (ACS).
This is a fork of Wayland's Weston compositor with some "additional advanced features". It all sounds pretty exciting when you look at what AMD developer Shashank Sharma noted on the GitLab Wiki page with these being the primary goals:
- To act as a staging area for Weston/Wayland features to be opensourced to mainline.
- To act as a reference compositor for AMD's advanced graphics and display feature development.
- To provide a middleware compositor which extracts the best out of AMD Display and Graphics HW (We don't mind being biased to AMDGPU HW)
- To host some of the AMD HW specific code, which can't be merged in weston mainline due to its bias towards AMD HW.
- To be utilised in full stack opensource delivery vehicle for AMDs commercial solutions and products.
- To be the space where AMD specific in-house SW tools (performance tweakers, multimedia players, 3D games, profiling tools etc) can be saved in future.

As noted on the Wiki page some initial features added include:
- VRR / Freesync.
- MPO using underlays.
- Color Management and Wide gamut support.
- ACS media-player app.
- Fullscreen HDR video playback.
- Multi-seat config support.
There's also a basic video player included to "demonstrate some of these advance feature in a video playback context".
This was announced on the dri-devel mailing list.

Hope that with ACS they may release Adrenalin Software for Linux in the future.
Including all or at least most features they have available for Windows.

Hopefully AMD can sort out the issue with HDMI 2.1 support.
Spent £3K on a TV and GPU but cannot use VRR or FREESYNC features due to a lack of driver support.
This problem may force me to drop AMD in favour of Nvidia. I do not want to do this though.

A few years too late.
Most of features are already implemented in KDE + MPV and on the way to Gnome.

Hopefully AMD can sort out the issue with HDMI 2.1 support.That will only work if they change the hardware in future cards, the issue is that AMD does HDMI in software and the HDMI consortium have forbidden them to release anything beyond 2.0 as open source. Intel solved this by only doing DP on their card and then have a hardware DP->HDMI chip and Nvidia solved it by having HDMI2.1 be done in their closed firmware.
