Smatch complains that "area_free" could be used without being
initialized. This code is several years old and premusably works fine
so this can't be a very serious bug. But it's easy enough to silence
the warning. If "area_free" is false at the end of the function then
we return -ENOMEM.

In the cleanup, I didn't notice that we needed to dereference the
connector for the bus_format. Fix the regression by looking up the
first (and only) connector attached to us, and assume that its
bus_format is what we want. Some day it would be good to have that
part of display_info attached to the bridge, instead.

Clear the old_state and new_state pointers for private objects
in drm_atomic_state_default_clear(). We don't actually have
functions to get the new/old state for private objects so
getting access to the potentially stale pointers requires a
bit more manual labour than for other object types. But let's
clear the pointers for private objects as well, if only to
avoid future surprises when someone decides to add the functions
to get at them.

Clear the old_state and new_state pointers for every object in
drm_atomic_state_default_clear(). Otherwise
drm_atomic_get_{new,old}_*_state() will hand out stale pointers to
anyone who hasn't first confirmed that the object is in fact part of
the current atomic transcation, if they are called after we've done
the ww backoff dance while hanging on to the same drm_atomic_state.
For example, handle_conflicting_encoders() looks like it could hit
this since it iterates the full connector list and just calls
drm_atomic_get_new_connector_state() for each.
And I believe we have now witnessed this happening at least once in
i915 check_digital_port_conflicts(). Commit 8b69449d2663 ("drm/i915:
Remove last references to drm_atomic_get_existing* macros") changed
the safe drm_atomic_get_existing_connector_state() to the unsafe
drm_atomic_get_new_connector_state(), which opened the doors for
this particular bug there as well.

We have to check dma-buf reservation objects of our framebuffers before
we use them. Otherwise, another driver might be writing on the same
buffer which we are using. This would cause visible tearing effects
on display.
We can use existing atomic helper functions to solve this problem.

The group objects assume linear indexing, and more so always assume that
channel 0 of any active group is used.
Now that the CRTC objects support non-linear indexing, adapt the groups
to remove assumptions that channel 0 is utilised in each group by using
the channel mask provided in the device structures.
Finally ensure that the RGB routing is determined from the index of the
CRTC object (which represents the hardware DU channel index).

The DU CRTC driver does not support distinguishing between a hardware
index, and a software (CRTC) index in the event that a DU channel might
not be populated by the hardware.
Support this by adapting the rcar_du_device_info structure to store a
bitmask of available channels rather than a count of CRTCs. The count
can then be obtained by determining the hamming weight of the bitmask.
This allows the rcar_du_crtc_create() function to distinguish between
both index types, and non-populated DU channels will be skipped without
leaving a gap in the software CRTC indexes.

Fix `[drm:intel_enable_lvds] *ERROR* timed out waiting for panel to
power on` in kernel log at boot time.
Toshiba Satellite Z930 laptops needs between 1 and 2 seconds to power
on its screen during Intel i915 DRM initialization. This currently
results in a `[drm:intel_enable_lvds] *ERROR* timed out waiting for
panel to power on` message appearing in the kernel log during boot
time and when stopping the machine.
This change increases the timeout of the `intel_enable_lvds` function
from 1 to 5 seconds, letting enough time for the Satellite 930 LCD
screen to power on, and suppressing the error message from the kernel
log.
This patch has been successfully tested on Linux 4.14 running on a
Toshiba Satellite Z930.
[vsyrjala: bump the timeout from 2 to 5 seconds to match the DP
code and properly cover the max hw timeout of ~4 seconds, and
drop the comment about the specific machine since this is not
a particulary surprising issue, nor specific to that one machine]

"An outstanding request must still be on an active ring somewhere" is
only true if we haven't just been interrupted by the shrinker in the
middle of allocating the request itself. (At the start of
i915_request_alloc() we pin the context and prepare the GT for activity,
marking it as active, and then try to allocate the request. If this
allocation invokes the shrinker, we try to reclaim some space by calling
i915_retire_requests() which may then be confused by the pre-reservation
of active_requests.)

With the previous patch drm_atomic_helper_check_plane_state correctly
calculates clipping and the xf86-video-intel ddx is fixed to fall back
to GPU correctly when SetPlane fails, we can remove the hack where
we try to pan/zoom when out of min/max scaling range. This was already
poor behavior where the screen didn't show what was requested, and now
instead we reject it outright. This simplifies check_sprite_plane a lot.
Changes since v1:
- Set crtc_h to the height correctly.
- Reject < 3x3 rectangles instead of making them invisible for <gen9.
For gen9+ skl_update_scaler_plane will reject them.

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.

When userspace is passing around swapbuffers using DRI, we frequently
have to open and close the same object in the foreign address space.
This shows itself as the same object being rebound at roughly 30fps
(with a second object also being rebound at 30fps), which involves us
having to rewrite the page tables and maintain the drm_mm range manager
every time.
However, since the object still exists and it is only the local handle
that disappears, if we are lazy and do not unbind the VMA immediately
when the local user closes the object but defer it until the GPU is
idle, then we can reuse the same VMA binding. We still have to be
careful to mark the handle and lookup tables as closed to maintain the
uABI, just allowing the underlying VMA to be resurrected if the user is
able to access the same object from the same context again.
If the object itself is destroyed (neither userspace keeping a handle to
it), the VMA will be reaped immediately as usual.
In the future, this will be even more useful as instantiating a new VMA
for use on the GPU will become heavier. A nuisance indeed, so nip it in
the bud.
v2: s/__i915_vma_final_close/i915_vma_destroy/ etc.
v3: Leave a hint as to why we deferred the unbind on close.

This driver will be used to support Mesa on the Broadcom 7268 and 7278
platforms.
V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's
complicated CL/shader validation scheme. This massively changes the
GEM behavior, so I've forked off to a new driver.
v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild
test robot. Drop personal git link from MAINTAINERS. Don't
double-map dma-buf imported BOs. Add kerneldoc about needing MMU
eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup
to mmap time. Use drm_dev_init instead of _alloc. Use
ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage,
since we don't modeset. Switch page tables back to WC (debug
change to coherent had slipped in). Switch
drm_gem_object_unreference_unlocked() to
drm_gem_object_put_unlocked(). Simplify overflow mem handling by
not sharing overflow mem between jobs.

I had originally asked Stefan Schake to drop the pad field from the
syncobj changes that just landed, because I couldn't come up with a
reason to align to 64 bits.
Talking with Dave Airlie about the new v3d driver's submit ioctl, we
came up with a reason: sizeof() on 64-bit platforms may align to 64
bits, in which case the userspace will be submitting the aligned size
and the final 32 bits won't be zero-padded by the kernel. If
userspace doesn't zero-fill, then a future ABI change adding a 32-bit
field at the end could potentially cause the kernel to read undefined
data from old userspace (our userspace happens to use structure
initialization that zero-fills, but as a general rule we try not to
rely on that in the kernel).

During state readout we first read out the pipe src size, store
that information in the user mode h/vdisplay, but later on we overwrite
that with the actual crtc timings. That makes our read out crtc state
inconsistent with itself when the BIOS has enabled the panel fitter to
scale the pipe contents. Let's preserve the pipe src size based
information in the user mode to make things consistent again.
This fixes a problem introduced by commit a2936e3d9a9c ("drm/i915:
Use drm_mode_get_hv_timing() to populate plane clip rectangle")
where the inconsistent state is now leading the plane clipping code
to report a failure on account the plane dst coordinates not matching
the user mode size. Previously we did the plane clipping based on
the pipe src size instead and thus never noticed the inconsistency.
The failure manifests as a WARN:

No functional changes, just a minor knit. Stumbled across the kernel doc for
schedule_timeout() which quotes "In all cases the return value is guaranteed
to be non-negative". Also, the return code of schedule_timeout() already checks
for negative values "return timeout < 0 ? 0 : timeout;" and returns 0
in such cases. Furthermore, the msec_to_jiffies returns an ungined long
value. So, let's do away with the redundant check for an atomic
pipe update.
v2: Commit message changes (Manasi).

With each bus implementing its own DMA configuration callback, there is no
need for bus to explicitly set the force_dma flag. Modify the
of_dma_configure function to accept an input parameter which specifies if
implicit DMA configuration is required when it is not described by the
firmware.
