Wayland Protocols 1.22 Released With DRM Object Leasing Support For VR HMDs
![WAYLAND](/assets/categories/wayland.webp)
The DRM lease protocol is modeled around Linux's Direct Rendering Manager (DRM) object leasing where the DRM master is able to "lease" a subset of resources to a client. In the case of this Wayland protocol it's about leasing DRM resources for exclusive use by a Wayland client.
As with the DRM leasing code itself, the Wayland DRM lease protocol is pushed along by virtual reality head-mounted displays. With this support, Wayland clients can now request exclusive access to a VR HMD. The X11 support around DRM leasing has been settled whole now with Wayland-Protocols 1.22 the protocol support is debuting in staging form.
There is code pending already for at least Sway/WLROOTS and KDE's KWin/KWaylandServer for lease support. GNOME Mutter developers have also looked at it as well. There is also XWayland DRM leasing patches pending.
The other mostly mundane changes with Wayland-Protocols 1.22 can be found via its release announcement.
