* gbm: Add gbm_surface interfaceAnder Conselvan de Oliveira2012-03-281-2/+19
| | | | | | | | | | | | The idea here is to be able to create an egl window surface from a gbm_surface. This avoids the need for the surfaceless extension and lets the EGL platform handle buffer allocation, while keeping the user in charge of somehow presenting the buffers (using kms page flipping, for example). gbm_surface_lock_front_buffer() locks a surface's front buffer and returns a gbm bo representing it. This bo should later be returned to the gbm surface using gbm_surface_release_buffer().
* gbm: track buffer format through DRI driversJesse Barnes2012-02-221-0/+1
| | | | | | | | | | | | GBM needs the buffer format in order to communicate with DRM and clients for things like scanout. So track the DRI format requested in the various back ends and use it to return the DRI format back to GBM when requested. GBM will then map this into the GBM surface type (which is in turn based on the DRM fb format list). Signed-off-by: Jesse Barnes <[email protected]>
