Previous Revision:
http://lists.freedesktop.org/archives/dri-devel/2013-November/049363.html
Changes since previous:
+ convert new properties over to DRM_MODE_PROP_EXTENDED_TYPE, so we
aren't consuming one new bit per property type (as suggested by, I
think, Ville)
+ Fixed usage of ww_ctx, split things out into 'struct drm_modeset_lock'
to make things easier when we start making locking even more fine
grained (ie. per-plane locks, etc)
+ Handle connector_ids changes better. In legacy setcrtc path, we
implicitly update other CRTCs that are having their connector stolen,
whereas in atomic ioctl there is no implicit connector stealing (ie.
this is an error if user does not also remove the connector from it's
current CRTC.
---------------------------------------------------------------------
Description from original RFC (with updated links):
This patchset is the merging of Ville's atomic modeset ioctl, and
the drm_{crtc,plane}_state stuff from my original nuclear pageflip
RFC.
It is currently working on msm with an updated version of Ville's
glplane test app (removing cursor properties and atomic event):
https://github.com/robclark/glplane
the libdrm bits can be found here:

The msm part is on top of msm-next, the complete branch can be found:
http://cgit.freedesktop.org/~robclark/linux/log/?h=global-thermonuclear-war-9
Compared to my earlier nuclear pageflip RFC, there is now a set of
drm_atomic helpers which do most of the non-hw-specific work for
the different drivers.
Unlike the crtc helpers, it is intended that the atomic helpers can
be used piecemeal by the drivers, either using all or overriding
parts as needed.
A naive driver, with no special constraints or hw support for atomic
updates may simply add the following to their driver struct:
.atomic_begin = drm_atomic_helper_begin,
.atomic_set_event = drm_atomic_helper_set_event,
.atomic_check = drm_atomic_helper_check,
.atomic_commit = drm_atomic_helper_commit,
.atomic_end = drm_atomic_helper_end,
.atomic_helpers = &drm_atomic_helper_funcs,
In addition, if you're plane/crtc doesn't already have it's own
custom properties, then add to your plane/crtc_funcs:
.set_property = drm_atomic_helper_{plane,crtc}_set_property,
A driver which can have (for example) conflicting modes across
multiple crtcs (for example, bandwidth limitations or clock/pll
configuration restrictions), can wrap drm_atomic_helper_check()
with their own driver specific .atomic_check() function.
A driver which can support true atomic updates can wrap
drm_atomic_helper_commit().
A driver with custom properties should override the appropriate
get_state(), check_state(), and commit_state() functions in
.atomic_helpers if it uses the drm-atomic-helpers. Otherwise it
is free to use &drm_atomic_helper_funcs as-is.
