Based on top of the 'prepare for preparing for atomic (v2)' series.
Since previous version posted, reshuffled a few things to pull some
changes ahead of atomic (in 'prepare for preparing..' patchset), and
few little fixes.
This patchset may be a bit more controversial for merging 3.16, but I
think it is worth considering. It certainly will need a few tweaks
as some drivers add native atomic support. And to handle all cases
when we actually expose the atomic ioctl to userspace, I think we
will need at least per-plane locks.
But merging now unblocks driver work. And I think the further changes
needed should not have much impact on drivers, at least no less than
if we merged atomic later.

The 'atomic' mechanism allows for multiple properties to be updated,
checked, and commited atomically. This will be the basis of atomic-
modeset and nuclear-pageflip.
The basic flow is:
state = dev->atomic_begin();
for (... one or more ...)
obj->set_property(obj, state, prop, value);
if (dev->atomic_check(state))
dev->atomic_commit(state);
dev->atomic_end(state);
The split of check and commit steps is to allow for ioctls with a
test-only flag (which would skip the commit step).

+/**
+ * DOC: atomic state helpers
+ *
+ * Base helper atomic state and functions. Drivers are free to either
+ * use these as-is, extend them, or completely replace them, in order
+ * to implement the atomic KMS API.
+ *
+ * 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_begin,
+ * .atomic_set_event = drm_atomic_set_event,
+ * .atomic_check = drm_atomic_check,
+ * .atomic_commit = drm_atomic_commit,
+ * .atomic_end = drm_atomic_end,
+ * .atomics = &drm_atomic_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_{plane,crtc}_set_property,
+ *
+ * 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 driver which can have (for example) conflicting modes across multiple
+ * crtcs (for example, bandwidth limitations or clock/pll configuration
+ * restrictions), can simply wrap drm_atomic_check() with their own
+ * driver specific .atomic_check() function.
+ *
+ * A driver which can support true atomic updates can wrap
+ * drm_atomic_commit().
+ *
+ * A driver with custom properties should override the appropriate get_state(),
+ * check_state(), and commit_state() functions in .atomics if it uses
+ * the drm-atomic-helpers. Otherwise it is free to use &drm_atomic_funcs
+ * as-is.

From: Rob Clark @ 2014-05-30 17:23 UTC (permalink / raw)
To: dri-devel
Split property values out into a different struct, so we can later
move property values into state structs. This will allow the
property values to stay in sync w/ the state updates which are
either discarded or atomically committed.
And since we are touching all the same code, add support for mutable
blob properties, which will also be needed for atomic modeset.

Break the mutable state of a plane out into a separate structure
and use atomic properties mechanism to set plane attributes. This
makes it easier to have some helpers for plane->set_property()
and for checking for invalid params. The idea is that individual
drivers can wrap the state struct in their own struct which adds
driver specific parameters, for easy build-up of state across
multiple set_property() calls and for easy atomic commit or roll-
back.
The same should be done for CRTC, encoder, and connector, but this
patch only includes the first part (plane).

From: Rob Clark @ 2014-05-30 17:23 UTC (permalink / raw)
To: dri-devel
Break the mutable state of a crtc out into a separate structure
and use atomic properties mechanism to set crtc attributes. This
makes it easier to have some helpers for crtc->set_property()
and for checking for invalid params. The idea is that individual
drivers can wrap the state struct in their own struct which adds
driver specific parameters, for easy build-up of state across
multiple set_property() calls and for easy atomic commit or roll-
back.
