Add reverse iterator for_each_oldnew_plane_in_state_reverse to
compliment the for_each_oldnew_plane_in_state way or reading plane
states.
The plane states are required to be read in reverse order for
amd drivers, cause the z order convention followed in linux is
opposite to how the planes are supposed to be presented to DC
engine, which is in common to both windows and linux.
V2: fix compile time errors due to -Werror flag.

570e86963a51 ("drm: Widen vblank count to 64-bits [v3]") changed the
return type for drm_crtc_vblank_count() to u64.
The flip ioctl receives a 32-bit target sequence from user space and is
compared against the current sequence from drm_crtc_vblank_count(). So,
typecast return from drm_crtc_vblank_count() explicitly to add clarity.
__drm_crtcs_state.last_vblank_count however only ever stores the value from
drm_crtc_vblank_count() and can be upgraded to u64.

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.

We don't want people to accidentally stumble over there.
Also rename the plane helpers to legacy plane helpers. After Ville's
patch to make the clipping helper atomic and move it to
drm_atomic_helper.c there's nothing left in there that should be
useful for modern drivers.
v2: Laurent had a few questions around how state is added to
drm_atomic_state, tried to clarify that. And spotted another sentence

DK put some nice docs into the commit introducing driver private
state, but in the git history alone it'll be lost.
Also, since Ville remove the void* usage it's a good opportunity to
give the driver private stuff some tlc on the doc front.
Finally try to explain why the "let's just subclass drm_atomic_state"
approach wasn't the greatest, and annotate all those functions as
deprecated in favour of more standardized driver private states. Also
note where we could/should extend driver private states going forward
(atm neither locking nor synchronization is handled in core/helpers,
which isn't really all that great).
v2: Spelling and phrasing improvements (Alex, DK).

Commit 669c9215afea ("drm/atomic: Make async plane update checks work as
intended, v2.") assumed incorrectly that if only 1 plane is matched in
the loop, the variables will be set to that plane. In reality we reset
them to NULL every time a new plane was iterated. This behavior is
surprising, so fix this by making the for loops only assign the
variables on a match.
When we have not added all the planes/crtc/connector to the state, and
there's a few NULL ones after the last one we iterated, te assumption
is broken that the pointers will hold the values from the last loop
iteration, which holds true for all other for_each macros we're using.
Except of course the iterator pointer itself, but that one really is
entirely internal.

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.

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.

In some cases, like cursor updates, it is interesting to update the
plane in an asynchronous fashion to avoid big delays. The current queued
update could be still waiting for a fence to signal and thus block any
subsequent update until its scan out. In cases like this if we update the
cursor synchronously through the atomic API it will cause significant
delays that would even be noticed by the final user.
This patch creates a fast path to jump ahead the current queued state and
do single planes updates without going through all atomic steps in
drm_atomic_helper_commit(). We take this path for legacy cursor updates.
For now only single plane updates are supported, but we plan to support
multiple planes updates and async PageFlips through this interface as well
in the near future.

It is necessary to track states for objects other than connector, crtc
and plane for atomic modesets. But adding objects like DP MST link
bandwidth to drm_atomic_state would mean that a non-core object will be
modified by the core helper functions for swapping and clearing
it's state. So, lets add void * objects and helper functions that operate
on void * types to keep these objects and states private to the core.
Drivers can then implement specific functions to swap and clear states.
The other advantage having just void * for these objects in
drm_atomic_state is that objects of different types can be managed in the
same state array.

Currently we use a flag to change behavior in atomic commit
whether a conflicting encoder should be enabled or disabled.
This is used for the legacy set_config helper, which disables
connectors that have a conflicting encoder but not part of the
active crtc list.
There's no need for this to be handled in atomic commit, it
could be done in the set_config helper instead. This will
let the atomic check function reject any conflicting encoders,
while set_config can disable conflicting crtc's. This makes it
possible to recalculate the changed flags in 1 loop.

Mostly because I want the links from the newly-added @state functions
to work. But I think explaining when they're useful and that the
implicit one is deprecated is good either way. Slightly repetitive

After atomic commit, these macros should be used in place of
get_existing_state. Also after commit get_xx_state should no longer
be used because it may not have the required locks.
The calls to drm_atomic_get_existing_$obj_state should no longer be
used, and converted over to these new calls.
Changes since v1:
- Expand commit message.
- Deprecate get_existing_*_state functions in the documentation.

Add for_each_(old)(new)_(plane,connector,crtc)_in_state iterators to
replace the old for_each_xxx_in_state ones. This is useful for >1 flip
depth and getting rid of all xxx->state dereferences.
This requires extra fixups done when committing a state after
duplicating, which in general isn't valid but is used by suspend/resume.
To handle these, introduce drm_atomic_helper_commit_duplicated_state
which performs those fixups before checking & committing the state.
Changes since v1:
- Remove nonblock parameter for commit_duplicated_state.
Changes since v2:
- Use commit_duplicated_state for i915 load detection.
- Add WARN_ON(old_state != obj->state) before swapping.

I just learned that &struct_name.member_name works and looks pretty
even. It doesn't (yet) link to the member directly though, which would
be really good for big structures or vfunc tables (where the

Also some minor drive-by polish where it makes sense, I read a lot

Currently if the userspace declares a int variable to store the out_fence
fd and pass it to OUT_FENCE_PTR the kernel will overwrite the 32 bits
above the int variable on 64 bits systems.
Fix this by making the internal storage of out_fence in the kernel a s32

Support DRM out-fences by creating a sync_file with a fence for each CRTC
that sets the OUT_FENCE_PTR property.
We use the out_fence pointer received in the OUT_FENCE_PTR prop to send
the sync_file fd back to userspace.
The sync_file and fd are allocated/created before commit, but the
fd_install operation only happens after we know that commit succeed.

- Rebase after fence -> dma_fence rename
- Store out_fence_ptr in the 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.

It's silly to have 2 mallocs when we could tie these two together.
Also, Gustavo adds another one in his per-crtc out-fence patches. And
I want to add more stuff here for nonblocking commit helpers.
In the future we can use this to store a pointer to the preceeding
state, making an atomic update entirely free-standing. This will be
needed to be able to queue them up with a depth > 1.

It's kinda pointless to have 2 separate mallocs for these. And when we

Right now there's no such thing planned, but both Gustavo's per-crtc
fence patches, and some nonblocking commit helpers I'm playing around

planes, just for consistency.
