There is no synchronization between processes (e.g. 3D app and compositor)
within X on AMD hw. It works because of some hacks in Mesa.

Many callers of drm_encoder_init use a drm_encoder_funcs
that contains only a drm_encoder_cleanup() callback.
drm_simple_encoder_init() was introduced to cover the
common case where an encoder with only basic functionality
was needed. But it really do not belong in drm_simple_*
Rename drm_encoder
Thomas Zimmermann had made a nice patch-set that introduced
drm_simple_encoder_init() which is already present in drm-misc-next.
While looking at this it was suddenly obvious to me that
this was functionalty that really should be included in drm_encoder.c
The case where the core could handle the c
A lot of drivers requires only a basic encoder with no need
to extend the functionality.
This was previously implemented in drm_simple_kms_helper.c
but encoders are not necessarily simple despite no
need for a drm_encoder_funcs for adding functionality.
Move the init function to drm_encoder.c to r
atmel-hlcdc has no need to extend the functionality of the
encoder, so use drm_encoder_init().
