The frame_busy mask is used in frame_done event handling, which is not
invoked for async commits. So an async commit will leave the
frame_busy mask populated after it completes and future commits will start
with the busy mask incorrect.
This showed up on disable after cursor move. I was hitting the "this should
not happen" comment in the frame event worker since frame_busy was set,
we queued the event, but there were no frames pending (since async
also doesn't set that).

In the case of an async/cursor update, we don't wait for the frame_done
event, which means handle_frame_done is never called, and the frame_done
watchdog isn't canceled. Currently, this results in a frame_done timeout
every time the cursor moves without a synchronous frame following it up
before the timeout expires. Since we don't wait for frame_done, and
don't handle it, we shouldn't modify the watchdog.

There exists a bunch of confusion as to what the actual units of
frame_done is:
- The definition states it's in # of frames
- CRTC treats it like it's ms
- frame_done_timeout comment thinks it's Hz, but it stores ms
- frame_done timer is setup such that it _should_ be in frames, but the
timeout is super long
So this patch tries to interpret what the driver really wants. I've
de-centralized the #define since the consumers are expecting different
units.
For crtc, we just use 60ms since that's what it was doing before.
Perhaps we could get fancy and scale with vrefresh, but that's for
another time.
For encoder, fix the comments and rename frame_done_timeout so it's
obvious what the units are. In practice, frame_done_timeout is really
just checked against 0 || !0, which I guess is why the units being wrong
didn't matter. I've also dropped the timeout from the previous 60 frames
to 5. That seems like more than enough time to give up on a frame, and
my guess is that no one intended for the timeout to _actually_ be 60
frames.

Devices that make up DPU, i.e. graphics card, request their interrupts
from this "virtual" interrupt chip. The interrupt chip builds upon a GIC
SPI interrupt that raises high when any of the interrupts in the DPU's
irq status register are triggered. From the kernel's perspective this is
a chained irq chip, so requesting a flow handler for the GIC SPI and
then calling generic IRQ handling code from that irq handler is not
completely proper. It's better to convert this to a chained irq so that
the GIC SPI irq doesn't appear in /proc/interrupts, can't have CPU
affinity changed, and won't be accounted for with irq stats. Doing this
also silences a recursive lockdep warning because we can specify a
different lock class for the chained interrupts, silencing a warning
that is easy to see with 'threadirqs' on the kernel commandline.

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

Instead of assigning/clearing the crtc on vblank enable/disable, we can
just assign and clear the crtc on modeset. That allows us to just toggle
the encoder's vblank interrupts on vblank_enable.
So why is this important? Previously the driver was using the legacy
pointers to assign/clear the crtc. Legacy pointers are cleared _after_
disabling the hardware, so the legacy pointer was valid during
vblank_disable, but that's not something we should rely on.
Instead of relying on the core ordering the legacy pointer assignments
just so, we'll assign the crtc in dpu_crtc enable/disable. This is the
only place that mapping can change, so we're covered there.
We're also taking advantage of drm_crtc_vblank_on/off. By using this, we
ensure that vblank_enable/disable can never be called while the crtc is
off (which means the assigned crtc will always be valid). As such, we
don't need to use modeset locks or the crtc_lock in the
vblank_enable/disable routine to be sure state is consistent.
...I think.

I think the intention here was to protect the enc->crtc access, but
that's insufficient to avoid enc->crtc changing. Fortunately we're
already holding the modeset lock when this is called (from
atomic_check), so remove the crtc_lock and add a modeset lock check.
While we're at it, use the encoder mask from crtc state instead of
legacy pointer.

There are 4 times that _dpu_crtc_vblank_enable_no_lock() is called:
1- crtc enable
2- crtc disable
3- crtc vblank enable
4- crtc vblank disable
When we enable or disable the crtc, we call drm_crtc_vblank_on and
drm_crtc_vblank_off respectively. That will gate vblank enables and
disables to only being called when the crtc is active. That means that
we can just enable/disable pm runtime in crtc enable/disable. This will
be beneficial in trying to eliminate blocking calls from the vblank call
chain.

The crtc runtime resume doesn't actually operate on the crtc, but rather
its encoders. The problem with this is that we need to inspect the crtc
state to get the currently connected encoders. Since runtime resume
isn't guaranteed to be called while holding the modeset locks (although
it sometimes is), this presents a race condition.
Now that we have ->enabled on the virtual encoders, and a lock to
protect it, just call resume on each encoder and only restore the ones
that are enabled.

This patch sprinkles a few async/legacy_cursor_update checks
through commit to ensure that cursor updates aren't blocked on vsync.
There are 2 main components to this, the first is that we don't want to
wait_for_commit_done in msm_atomic before returning from atomic_complete.
The second is that in dpu we don't want to wait for frame_done events when

There exists a case where a flush of a plane/dma may have been triggered
& started from an async commit. If that plane/dma is subsequently disabled
by the next commit, the flush register will continue to hold the flush
bit for the disabled plane. Since the bit remains active,
pending_kickoff_cnt will never decrement and we'll miss frame_done
events.
This patch limits the check of flush_register to include only those bits
which have been updated with the latest commit.

In case of msm drm bind failure, dpu_mdss_destroy is triggered.
In this function, resources are freed and pm runtime disable is
called, which triggers dpu_mdss_disable. Now in dpu_mdss_disable,
driver tries to access a memory which is already freed. This
results in kernel panic. Fix this by ensuring proper sequence

4.19 is out, Lyude asked for a backmerge, and it's been a while. All
very good reasons on their own :-)

We are currently leaking a drm_crtc_commit struct for every atomic
commit containing plane state. The dpu plane destroy function cleans up
the fb reference manually, but fails to release the commit ref. As a
result, we just keep allocating drm_crtc_commits without ever freeing
them. Fortunately there's a helper function which will clean up all of
our mess at once, so use that.
Thanks to Doug Anderson for reporting the memory leak (and leaving
breadcrumbs from kmemleak!).

As done treewide earlier, this catches several more open-coded
allocation size calculations that were added to the kernel during the
merge window. This performs the following mechanical transformations
using Coccinelle:
kvmalloc(a * b, ...) -> kvmalloc_array(a, b, ...)
kvzalloc(a * b, ...) -> kvcalloc(a, b, ...)
devm_kzalloc(..., a * b, ...) -> devm_kcalloc(..., a, b, ...)

drm_plane_helper_disable is a non-atomic drivers only function, and
will blow up (since no one passes the locking context it needs).
Atomic drivers which want to quiescent their hw on unload should
use drm_atomic_helper_shutdown() instead.

The return from the call to _mixer_stages can be a negative error
code however this is being assigned to an unsigned variable 'stages'
hence the check is always false. Fix this by making 'stages' an
int.

stages < 0")

cur_master in dpu_encoder is assigned at modeset and cleared on
.disable(). Unfortunately dpms (or enable/disable) does not guarantee a
modeset, so cur_master is NULL when we try to re-enable it.
This patch moves the NULL assignment to setup_display where it will be
re-assigned later in the function.

Remove unneeded checks from _dpu_plane_get_aspace.

Removed all impossible checks from the function, which eliminates
the need for a return value. This function is also never used
outside of dpu_plane.c, so the function is made static.

it locally.

All checks for _dpu_crtc_power_enable are not true, so the function
can never return an error code. This removes the need for the
function as pm_runtime functions can be used instead.
v3: Separated _dpu_crtc_power_enable into _dpu_crtc_power_enable and
_dpu_crtc_power_disable for clarity.
v4: Removed both _dpu_crtc_power_enable and _dpu_crtc_power_disable
and called pm_runtime_get_sync and pm_runtime_put_sync from all
call points
