Jyri Sarha 80f690e9e3 drm: Add optional COLOR_ENCODING and COLOR_RANGE properties to drm_plane
Add a standard optional properties to support different non RGB color
encodings in DRM planes. COLOR_ENCODING select the supported non RGB
color encoding, for instance ITU-R BT.709 YCbCr. COLOR_RANGE selects
the value ranges within the selected color encoding. The properties
are stored to drm_plane object to allow different set of supported
encoding for different planes on the device.

Maarten Lankhorst 669c9215af drm/atomic: Make async plane update checks work as intended, v2.
By always keeping track of the last commit in plane_state, we know
whether there is an active update on the plane or not. With that
information we can reject the fast update, and force the slowpath
to be used as was originally intended.

We cannot use plane_state->crtc->state here, because this only mentions
the most recent commit for the crtc, but not the planes that were part
of it. We specifically care about what the last commit involving this
plane is, which can only be tracked with a pointer in the plane state.

Changes since v1:
- Clean up the whole function here, instead of partially earlier.
- Add mention in the commit message why we need commit in plane_state.
- Swap plane->state in intel_legacy_cursor_update, instead of
  reassigning all variables. With this commit We know that the cursor
  is not part of any active commits so this hack can be removed.

Maarten Lankhorst 21a01abbe3 drm/atomic: Fix freeing connector/plane state too early by tracking commits, v3.
Currently we neatly track the crtc state, but forget to look at
plane/connector state.

When doing a nonblocking modeset, immediately followed by a setprop
before the modeset completes, the setprop will see the modesets new
state as the old state and free it.

This has to be solved by waiting for hw_done on the connector, even
if it's not assigned to a crtc. When a connector is unbound we take
the last crtc commit, and when it stays unbound we create a new
fake crtc commit for that gets signaled on hw_done for all the
planes/connectors.

We wait for it the same way as we do for crtc's, which will make
sure we never run into a use-after-free situation.

Changes since v1:
- Only create a single disable commit. (danvet)
- Fix leak in intel_legacy_cursor_update.
Changes since v2:
- Make reference counting in drm_atomic_helper_setup_commit
  more obvious. (pinchartl)
- Call cleanup_done for fake commit. (danvet)
- Add comments to drm_atomic_helper_setup_commit. (danvet, pinchartl)
- Add comment to drm_atomic_helper_swap_state. (pinchartl)

Daniel Vetter 144a7999d6 drm: Handle properties in the core for atomic drivers
The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.

But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.

And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.

This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.

v2: Fixup docs even better!

v3: Make it actually work ...

v4: Drop the uses_atomic_modeset() checks from the previous patch
again, since they're now moved up in the callchain.

Ville Syrjälä 38d868e41c drm: Don't force all planes to be added to the state due to zpos
We don't want all planes to be added to the state whenever a
plane with fixed zpos gets enabled/disabled. This is true
especially for eg. cursor planes on i915, as we want cursor
updates to go through w/o throttling. Same holds for drivers
that don't support zpos at all (i915 actually falls into this
category right now since we've not yet added zpos support).

Allow drivers more freedom by letting them deal with zpos
themselves instead of doing it in drm_atomic_helper_check_planes()
unconditionally. Let's just inline the required calls into all
the driver that currently depend on this.

v2: Inline the stuff into the drivers instead of adding another
    helper, document things better (Daniel)

Chris Wilson f54d186700 dma-buf: Rename struct fence to dma_fence
I plan to usurp the short name of struct fence for a core kernel struct,
and so I need to rename the specialised fence/timeline for DMA
operations to make room.

A consensus was reached in
https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html
that making clear this fence applies to DMA operations was a good thing.
Since then the patch has grown a bit as usage increases, so hopefully it
remains a good thing!

(v2...: rebase, rerun spatch)
v3: Compile on msm, spotted a manual fixup that I broke.

Ville Syrjälä d138dd3c0c drm: Add support for optional per-plane rotation property
Not all planes on the system may support the same rotations/reflections,
so make it possible to create a separate property for each plane.
This way userspace gets told exactly which rotations/reflections are
possible for each plane.

v2: Add drm_plane_create_rotation_property() helper
v3: Drop the BIT(), __builtin_ffs(x) - 1,
    Moar WARNs for bad parameters
    Deal with superfluous code shuffling

Chris Wilson 0853695c3b drm: Add reference counting to drm_atomic_state
drm_atomic_state has a complicated single owner model that tracks the
single reference from allocation through to destruction on another
thread - or perhaps on a local error path. We can simplify this tracking
by using reference counting (at a cost of a few more atomics). This is
even more beneficial when the lifetime of the state becomes more
convoluted than being passed to a single worker thread for the commit.

v2: Double check !intel atomic_commit functions for missing gets
v3: Update kerneldocs

Daniel Vetter 226714dc7c drm: Fix plane type uabi breakage
Turns out assuming that only stuff in uabi is uabi is a bit naive, and
we have a bunch of properties for which the enum values are placed in
random headers. A proper fix would be to split out uapi include
headers, but meanwhile sprinkle at least some warning over them.

Daniel Vetter 532b36712d drm/doc: Polish for drm_plane.[hc]
Big thing is untangling and carefully documenting the different uapi
types of planes. I also sprinkled a few more cross references around
to make this easier to discover.

As usual, remove the kerneldoc for internal functions which are not
exported. Aside: We should probably go OCD on all the ioctl handlers
and consistenly give them an _ioctl postfix.

Daniel Vetter 43968d7b80 drm: Extract drm_plane.[hc]
Just pure code movement, cleanup and polish will happen in later
patches.

v2: Don't forget all the ioctl! To extract those cleanly I decided to
put check_src_coords into drm_framebuffer.c (and give it a
drm_framebuffer_ prefix), since that just checks framebuffer
constraints.

v3: rebase over PAGE_FLIP_TARGET.

    drm: Reject page_flip for !DRIVER_MODESET

so as a result of moving the page_flip ioctl, this fix has
been rolled into this patch.
