Patch series that adds support for DRM leases.
DRM leases is a method developed by Keith Packard to allow other application
manage the output of a display/VR, while a DRM master is already owning
the outputs resources. A more thorough explanation and terminology can
be found at [1]. libdrm [2] and kernel [3] have already gained support.
Initially this was a single patch but decided to split into series to
accommodate a demo client and another change as to allow a smoother transition
of the output from weston to a DRM leased client.
Marius Vlad (3):
compositor-drm: Add support for drm-lease.
compositor-drm: Do not perform a modeset when the output has been
leased
clients/simple-egl-lease: A demo client for DRM leases
