Summary: How to find which DRI version is used by Wayland, and
what is the method to change DRI version on Wayland?
Product: Wayland
Version: 1.4.0
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: wayland
Assignee: wayland-bugs@lists.freedesktop.org
Reporter: nobodyl...@gmail.com
How to find which DRI version is used by/beneath Wayland, and what is the
method to change DRI version on Wayland (if any)?
Short description of the problem: We have GNOME using Wayland, which uses
DRIlib beneath protocol and compositor, and DRI connects to the DRM
(generic/transparent for various DRIs), which is wrapper around GFX kernel
drivers for the specific integrated GPUs and/or GPUs on the PCIe cards.
I assume Xorg server has both implementations for DRIs (DRI2 and DRI3) beneath
X11 protocol. If DRM hooks up GFX kernel driver which uses DRI2 I/F, it'll
connect to DRI2lib. If DRI3 I/F, DRM will hook to DRI3lib.
[1] How does this architecture work for Wayland? Does Wayland support both DRI2
and DRI3 (e,g. had both DRI2lib and DRI3lib APIs integrated within Wayland
server)?
[2] Could this be changes/enforced the same way as for Xorg server (in
/etc/X11/xorg.conf?
[3] Does this (what I wrote here) make any sense??? ;-)
Thank you,
_nobody_
