Subject: [PATCH xserver 02/27] xwayland: move formats and modifiers functions
to common glamor code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This is preliminary work for hardware accelerated rendering with the
NVIDIA driver.
This moves the modifiers and formats functions previously only available
to the GBM backend to the common glamor code so that it can be used by
both the GBM and EGLStream backends.
Reviewed-by: Michel Dänzer <mdaenzer@redhat.com>
