Using += to set the bits in a mask looks funny. It works in this case
because we never set the same bit twice. But let's switch to |= to
make this look more regular.

Writeback connectors represent writeback engines which can write the
CRTC output to a memory framebuffer. Add a writeback connector type and
related support functions.
Drivers should initialize a writeback connector with
drm_writeback_connector_init() which takes care of setting up all the
writeback-specific details on top of the normal functionality of
drm_connector_init().
Writeback connectors have a WRITEBACK_FB_ID property, used to set the
output framebuffer, and a WRITEBACK_PIXEL_FORMATS blob used to expose the
supported writeback formats to userspace.
When a framebuffer is attached to a writeback connector with the
WRITEBACK_FB_ID property, it is used only once (for the commit in which
it was included), and userspace can never read back the value of
WRITEBACK_FB_ID. WRITEBACK_FB_ID can only be set if the connector is
attached to a CRTC.
Changes since v1:
- Added drm_writeback.c + documentation
- Added helper to initialize writeback connector in one go
- Added core checks
- Squashed into a single commit
- Dropped the client cap
- Writeback framebuffers are no longer persistent
Changes since v2:
Daniel Vetter:
- Subclass drm_connector to drm_writeback_connector
- Relax check to allow CRTC to be set without an FB
- Add some writeback_ prefixes
- Drop PIXEL_FORMATS_SIZE property, as it was unnecessary
Gustavo Padovan:
- Add drm_writeback_job to handle writeback signalling centrally
Changes since v3:
- Rebased
- Rename PIXEL_FORMATS -> WRITEBACK_PIXEL_FORMATS
Chances since v4:
- Embed a drm_encoder inside the drm_writeback_connector to
reduce the amount of boilerplate code required from the drivers
that are using it.
Changes since v5:
- Added Rob Clark's atomic_commit() vfunc to connector helper
funcs, so that writeback jobs are committed from atomic helpers
- Updated create_writeback_properties() signature to return an
error code rather than a boolean false for failure.
- Free writeback job with the connector state rather than when
doing the cleanup_work()
Changes since v7:
- fix extraneous use of out_fence that is only introduced in a
subsequent patch.
Changes since v8:
- whitespace changes pull from subsequent patch
Changes since v9:
- Revert the v6 changes that free the writeback job in the connector
state cleanup and return to doing it in the cleanup_work() function

Stop playing around with plane->crtc/fb/old_fb with atomic
drivers. Make life a lot simpler when we don't have to do the
magic old_fb vs. fb dance around plane updates. That way we
can't risk plane->fb getting out of sync with plane->state->fb
and we're less likely to leak any refcounts as well.

Instead of relying on a scale which may increase rounding errors,
clip src by doing: src * (dst - clip) / dst and rounding the result
away from 1, so the new coordinates get closer to 1. We won't need
to fix up with a magic macro afterwards, because our scaling factor
will never go to the other side of 1.
Changes since v1:
- Adjust dst immediately, else drm_rect_width/height on dst gives bogus
results.
Change since v2:
- Get rid of macros and use 64-bits math.

drm_atomic_helper_shutdown()
drm_atomic_helper_shutdown() needs to release the reference held by
plane->fb. Since commit 49d70aeaeca8 ("drm/atomic-helper: Fix leak in
disable_all") we're doing that by calling drm_atomic_clean_old_fb() in
drm_atomic_helper_disable_all(). This also leaves plane->fb == NULL
afterwards. However, since drm_atomic_helper_disable_all() is also
used by the i915 gpu reset code
drm_atomic_helper_commit_duplicated_state() then has to undo the
damage and put the correct plane->fb pointers back in (and also
adjust the ref counts to match again as well).
That approach doesn't work so well for load detection as nothing
sets up the plane->old_fb pointers for us. This causes us to
leak an extra reference for each plane->fb when
drm_atomic_helper_commit_duplicated_state() calls
drm_atomic_clean_old_fb() after load detection.
To fix this let's call drm_atomic_clean_old_fb() only for
drm_atomic_helper_shutdown() as that's the only time we need to
actually drop the plane->fb references. In all the other cases
(load detection, gpu reset) we want to leave plane->fb alone.
v2: Don't inflict the clean_old_fbs bool to drivers (Daniel)
v3: Squash in the revert and rewrite the commit msg (Daniel)

During a non-blocking commit, it is possible to return before the
commit_tail work is queued (-ERESTARTSYS, for example).
Since a reference on the crtc commit object is obtained for the pending
vblank event when preparing the commit, the above situation will leave
us with an extra reference.
Therefore, if the commit_tail worker has not consumed the event at the
end of a commit, release it's reference.
Changes since v1:
- Also check for state->event->base.completion being set, to
handle the case where stall_checks() fails in setup_crtc_commit().
Changes since v2:
- Add a flag to drm_crtc_commit, to prevent dereferencing a freed event.
i915 may unreference the state in a worker.

drm_atomic_helper_setup_commit expects that flipping of previous commits
has happened when it is called to set up a new commit. This can be violated
by commits where userspace doesn't get a flip completion event to
synchronize against i.e. legacy modesets and property changes.
The expectation is that those are done by blocking commits, which wait for
completion. Most drivers call drm_atomic_helper_wait_for_vblanks in the
commit_tail to ensure completion, but the wait for next vblank might not
actually happen if the commit didn't change any planes.
Make the wait more agressive by also waiting if no planes changed. This
is the minimal regression fix for the 4.15 kernel series. Long term
drivers should switch away from drm_atomic_helper_wait_for_vblanks and
use drm_atomic_helper_wait_for_flip_done instead.

At least when they have vblank support they need to call this, or the
vblank core will happily call into their crtc->enable_vblank callback
even when the crtc is off. Which leads to a boom when the clocks are
off on most hardware (besides the inevitable confusion in the
book-keeping).
The consistency checks in drm_vblank.c will then make sure that
vblank_off/on calls are balanced, and if drivers forget to re-enable
it all the commits will stall, so I think we're covered.
It'd be nice to be able to place this check outside of commit helpers,
but tha's not really possible (due to nonblocking commits and all
that). Placing it into atomic helpers should at least cover most
drivers.
Also note that vblank support is still optional (for virtual drivers,
which tend to not have this), check for that.
v2: Fixup the handling for vblank_put (Rob).

We still want to fail with -EBUSY if a plane or connector is part of
a commit, even if it will be assigned to a new commit.
This closes a small hole left open where we should return -EBUSY.
It's not severe, because wait_for_dependencies and swap_state helpers
still block. But it should return -EBUSY and not stall.

Commit 669c9215afea ("drm/atomic: Make async plane update checks work as
intended, v2.") forced planes to always be tracked, but forgot to
explicitly get the crtc commit from the new crtc when available.
This broke plane commit tracking, and caused kms_atomic_transitions
to randomly fail with -EBUSY.
Changes since v1:
- Prefer new_crtc_state->crtc above old_crtc_state->crtc.

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.

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)

When commit synchronization through drm_crtc_commit was first
introduced, we tried to solve the problem of the flip_done
needing a reference count by blocking in cleanup_done.
This has been changed by commit 24835e442f28 ("drm: reference count
event->completion") which made the waits here no longer needed.
However, even after this commit we still needed the wait because
otherwise we cannot wait for the flip_done because this item might
have been removed from the list.
Changed since v1:
- Make mention of cleanup_done completing before flip_done.

Most code only cares about the current commit or previous commit.
Fortuantely we already have a place to track those. Move it to
drm_crtc_state where it belongs. :)
The per-crtc commit_list is kept for places where we have to look
deeper than the current or previous commit for checking whether to stall
on unpin. This is used in drm_atomic_helper_setup_commit and
intel_has_pending_fb_unpin.

It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_helper_connector_set_property.
The only special case is nouveau which used one function for both
pre-nv50 legacy modeset code and post-nv50 atomic world instead of 2
vtables. But amounts to exactly the same.
What is rather strange here is how few drivers set this up, I suspect
the earlier patch to handle properties in the core did end up fixing a
pile of possible issues.

Atomic drivers only use the property value store for immutable (i.e.
can't be set by userspace, but the kernel can still adjust it)
properties. The only tricky part is the removal of the update in
drm_atomic_helper_update_legacy_modeset_state().
This was added in

drm/atomic: Update legacy DPMS state during modesets, v3.
by copying it from the i915 code, where it was originally added in
commit 68d3472047a572936551f8ff0b6f4016c5a1fdef
Author: Daniel Vetter <daniel.vetter@ffwll.ch>

drm/i915: update dpms property in set_mode
for the legacy modeset code. The reason we needed this hack was that
i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of
the newer-ish drm_drv_uses_atomic_modeset(), which avoids such
troubles. With the correct feature checks this isn't needed anymore at
all.
Also make sure that drivers don't accidentally get this wrong by
making the exported version of drm_object_property_get_value() only
work for legacy drivers. Only gma500 uses it anyway.

again.
for_each_obj_in_state is about to be removed, so use the correct new
iterator macro.
I renamed the variable to 'unused', but forgot to convert
drm_atomic_helper_wait_for_flip_done to the new iterator macro,
so make it work this time.

Resync with upstream to avoid git getting too badly confused. Also, we
have a conflict with the drm_vblank_cleanup removal, which cannot be
resolved by simply taking our side. Bake that in properly.

The current drm_atomic_helper_commit_tail helper works only if the CRTC is
accessible, and documents an alternative implementation that is supposed to
be used if that happens.
That implementation is then duplicated by some drivers. Instead of
documenting it, let's implement an helper that all the relevant users can
use directly.

We want to change swap_state to wait indefinitely, but to do this
swap_state should wait interruptibly. This requires propagating
the error to each driver.
