VK_EXT_full_screen_exclusive - will this be useful for freesync support?

No, vulkan is drawing api. Freesync depends on support from the display drivers and x11 (and wayland compositors).

Vulkan is not a drawing API. Vulkan is GPU programming API. radeonsi had to add support for it, so I assume radv / amdvlk will have to as well. May be bypassing the compositor will allow Vulkan driver control framerate according to whatever the kernel VRR features communicate.

This extension is win32 only in the spec. Mostly for the app to control whether to use the windows concept of exclusive fullscreen or borderless windowed fullscreen.

Good to know, thanks! Is there some work that needs to be done to enable adaptive sync with radv?

[aufkrawall]

On Windows with Vulkan, Nvidia doesn't support fullscreen exclusive, while AMD doesn't support borderless. What a mess.
On Xorg, we already have full control whether the compositor stays enabled or not.

I ported whatever radeonsi does to radv in this patch: https://gitlab.freedesktop.org/bnieu...mmits/freesync

However, I've had someone tell me that it does not work for him, and lacking a freesync monitor (or any good testing plan really) I haven't spend a lot of effort on finding the issue. You're welcome to try, a second test result is always welcome (but before you report, please make sure freesync works with radeonsi on your setup so we can isolate issues)

I'd like to, but I don't have such monitor either yet. It's kind of an chicken and egg problem - I'm waiting with buying a FreeSync capable monitor before radv and KWin will catch up with it... It would be a bit annoying to get some 144 Hz 2560x1440 monitor that will be forcing 144 Hz all the time causing games to be out of sync.

Hopefully someone with such monitors can help testing it. Feel free to post a request for it here:

I'm sure you can find some gamers there with Freesync capable monitors who would be interested in helping testing it with radv.

Good day, i could test if goes to Mesa-Git.
