When drm_crtc_init_with_planes() was orignally added
(in drm_crtc.c, e13161af80c185ecd8dc4641d0f5df58f9e3e0af
drm: Add drm_crtc_init_with_planes() (v2)), it only checked for "primary"
being non-null. If that was the case, it modified primary->possible_crtcs.
Then, when support for cursor planes was added
(fc1d3e44ef7c1db93384150fdbf8948dcf949f15 drm: Allow drivers to register
cursor planes with crtc), the same behaviour was implemented for cursor
planes.
vc4_plane_init() since its inception has passed 0xff as "possible_crtcs"
parameter to drm_universal_plane_init(). With a change in drm_crtc.c
(7abc7d47510c75dd984380ebf819616e574c9604 drm: don't override
possible_crtcs for primary/cursor planes) passing 0xff results in primary's
possible_crtcs set to 0xff (cursor was updated manually by vc4_crtc.c).
Consequently, it would be allowed to use the primary plane from CRTC 1 (for
example) on CRTC 0, which would result in the overlay and cursors being
buried.

When we restart the engines, and we have active requests, a request on
the first engine may complete and queue a request to the second engine
before we try to restart the second engine. That queueing of the
request may race with the engine to restart, and so may corrupt the
current state. Disabling the engine->irq_tasklet prevents the two paths
from writing into ELSP simultaneously (and modifyin the execlists_port[]
at the same time).

Currently we do a reset prepare/finish around the call to reset the GPU,
but it looks like we need a later stage after the hw has been
reinitialised to allow GEM to restart itself. Start by splitting the 2
GEM phases into 3:
prepare - before the reset, check if GEM recovered, then stop GEM
reset - after the reset, update GEM bookkeeping
finish - after the re-initialisation following the reset, restart GEM

With the cdclk state, all the .modeset_commit_cdclk() hooks are
now pointless wrappers. Let's replace them with just a .set_cdclk()
function pointer. However let's wrap that in a small helper that
does the state comparison and prints a unified debug message across
all platforms. We didn't even have the debug print on all platforms
previously. This reduces the clutter in intel_atomic_commit_tail() a
little bit.

The current dev_cdclk vs. cdclk vs. atomic_cdclk_freq is quite a mess.
So here I'm introducing the "actual" and "logical" naming for our
cdclk state. "actual" is what we'll bash into the hardware and "logical"
is what everyone should use for state computaion/checking and whatnot.
We'll track both using the intel_cdclk_state as both will need other
differing parameters than just the actual cdclk frequency.
While doing that we can at the same time unify the appearance of the
.modeset_calc_cdclk() implementations a little bit.
v2: Commit dev_priv->cdclk.actual since that already has the
new state by the time .modeset_commit_cdclk() is called.

Introduce intel_cdclk state which for now will track the cdclk
frequency, the vco frequency and the reference frequency (not sure we
want the last one, but I put it there anyway). We'll also make the
.get_cdclk() function fill out this state structure rather than
just returning the current cdclk frequency.
One immediate benefit is that calling .get_cdclk() will no longer
clobber state stored under dev_priv unless ex[plicitly told to do
so. Previously it clobbered the vco and reference clocks stored
there on some platforms.
We'll expand the use of this structure to actually precomputing the
state and whatnot later.

Let's clean up the mess we have in the if ladder that assigns the
.get_cdclk() hooks. The grouping of the platforms by the function
results in a thing that's not really legible, so let's do it the
other way around and order the if ladder by platform and duplicate
whatever assignments we need.
To further avoid confusion with the function names let's rename
them to just fixed_<freq>_get_cdclk(). The other option would
be to duplicate the functions entirely but it seems quite
pointless to do that since each one just returns a fixed value.

We're using non-canonical addresses in drm_mm, and we're making sure that
userspace is using canonical addressing - both in case of softpin
(verifying incoming offset) and when relocating (converting to canonical
when updating offset returned to userspace).
Unfortunately when considering the need for relocations, we're comparing
offset from userspace (in canonical form) with drm_mm node (in
non-canonical form), and as a result, we end up always relocating if our
offsets are in the "problematic" range.
Let's always convert the offsets to avoid the performance impact of
relocations.

Apparently there are machines out there with Skylake CPU and KabyPoint
PCH. Judging from our driver code, there doesn't seem to be any code
paths that would do anything different between SunrisePoint and
KabyPoint PCHs, so it would seem okay to accept the combo without
warnings.

Commit 920cf4194954ec ("drm/i915: Introduce an internal allocator for
disposable private objects") introduced a regression for the kernel
running as Xen dom0: when switching to graphics mode a GPU HANG
occurred.
Reason seems to be a missing adaption similar to that done in
commit 7453c549f5f648 ("swiotlb: Export swiotlb_max_segment to users")
to i915_gem_object_get_pages_internal().
So limit the maximum page order to be used according to the maximum
swiotlb segment size instead to the complete swiotlb size.

On a non-llc system, the objects are created with .cache_level =
CACHE_NONE and so the transition to uncached for scanout is a no-op.
However, if the object was never written to, it will still be in the CPU
domain (having been zeroed out by shmemfs). Those cachelines need to be
flushed prior to display.

We're using non-canonical addresses in drm_mm, and we're making sure that
userspace is using canonical addressing - both in case of softpin
(verifying incoming offset) and when relocating (converting to canonical
when updating offset returned to userspace).
Unfortunately when considering the need for relocations, we're comparing
offset from userspace (in canonical form) with drm_mm node (in
non-canonical form), and as a result, we end up always relocating if our
offsets are in the "problematic" range.
Let's always convert the offsets to avoid the performance impact of
relocations.

If dsi_connector fails to allocate, the exit path via label 'fail'
checks if connector is null, which it always is, so the cleanup
that destroys connector is never going to be called. Hence the
failure path can be more optimally performed by removing this
and just returning ERR_PTR(-ENOMEM). This also removes the need
to initialize connector to NULL, and we can also remove ret too.

Following a reset, the context and page directory registers are lost.
However, the queue of requests that we resubmit after the reset may
depend upon them - the registers are restored from a context image, but
that restore may be inhibited and may simply be absent from the request
if it was in the middle of a sequence using the same context. If we
prime the CCID/PD registers with the first request in the queue (even
for the hung request), we prevent invalid memory access for the
following requests (and continually hung engines).
v2: Magic BIT(8), reserved for future use but still appears unused.
v3: Some commentary on handling innocent vs guilty requests
v4: Add a wait for PD_BASE fetch. The reload appears to be instant on my
Ivybridge, but this bit probably exists for a reason.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.
As the result, exynos_drm_crtc_enable[disable]_vblank() become static
functions. They are moved around a bit to save forward declaration
though. Also while at it, we move one step further to kill
exynos_drm_crtc_from_pipe() completely by updating hdmi_bind() a bit.
