Poke at the CBR1_VLV register during init_clock_gating to make sure the
PND deadline scheme is used.
The hardware has two modes of operation wrt. watermarks:
1) PND deadline mode:
- memory request deadline is calculated from actual FIFO level * DDL
- WM1 watermark values are unused (AFAIK)
- WM watermark level defines when to start fetching data from memory
(assuming trickle feed is not used)
2) backup mode
- deadline is based on FIFO status, DDL is unused
- FIFO split into three regions with WM and WM1 watermarks, each
part specifying a different FIFO status
We want to use the PND deadline mode, so let's make sure the chicken
bit is in the correct position on init.
Also take the opportunity to refactor the shared code between VLV and
CHV to a shared function.

We need to disable all sprite planes when disabling the CRTC. We had
been using the top-level atomic 'disable' entrypoint to accomplish this,
which was wrong. Not only can this lead to various locking issues, it
also modifies the actual plane state, making it impossible to restore
the plane properly later. For example, a DPMS off followed by a DPMS on
will result in any sprite planes in use not being restored properly.
The proper solution here is to call directly into our 'commit plane'
hook with a copy of the plane's current state that has 'visible' set to
false. Committing this dummy state will turn off the plane, but will
not touch the actual plane->state pointer, allowing us to properly
restore the plane state later.

If the requested size is less than what the full range
of pdps can address, we end up setting pdps for only the
requested area.
The logical context however needs all pdp entries to be valid.
Prior to commit 06fda602db ("drm/i915: Create page table allocators")
we have been writing pdp entries with dma address of zero instead
of valid pdps. This is supposedly bad even if those pdps are not
addressed.
As commit 06fda602db ("drm/i915: Create page table allocators")
introduced more dynamic structure for pdps, we ended up oopsing
when we populated the lrc context. Analyzing this oops revealed
the fact that we have not been writing valid pdps with bsw, as
it is doing the ppgtt init with 2GB limit in some cases.
We should do the right thing and setup the non addressable part
pdps/pde/pte to scratch page through the minimal structure by
having just pdp with pde entries pointing to same page with
pte entries pointing to scratch page.
But instead of going through that trouble, setup all the pdps
through individual pd pages and pt entries, even for non
addressable parts. And let the clear range point them to scratch
page. This way we populate the lrc with valid pdps and wait
for dynamic page allocation work to land, and do the heavy lifting
for truncating page table tree according to usage.
The regression of oopsing in init was introduced by
commit 06fda602db ("drm/i915: Create page table allocators")

We've been a bit too optimistic with this one here :(
The trouble is that internally we're still using these plane
update/disable hooks. Which was totally ok pre-atomic since the drm
core did all the book-keeping updating and these just mostly updated
hw state. But with atomic there's lots more going on, and it causes
heaps of trouble with the load detect code.
This one specifically cause a deadlock since both the load detect code
and the nested plane atomic helper functions tried to grab the same
locks. It only blows up because of the evil tricks though we play with
the implicit ww acquire context.
Applying this revert unearths the NULL deref on already freed
framebuffer objects reported as a regression in 4.0 by various people.
Fixing this will be fairly invasive, hence revert even for the

We shouldn't tempt driver writers into using this since it uses a
default format list which is likely wrong. And when that's done we can
simplify the code a bit, too.
Noticed while reviewing a patch from Laurent.

Both the legacy and atomic helpers need to check whether a plane
supports a given pixel format. The code is currently duplicated, share
it.

Originally it was impossible to be dropping the last refcount in this
function since there was always one around still from the idr. But in

drm: Don't grab an fb reference for the idr
we've switched to weak references, broke that assumption but forgot to
fix it up.
Since we still force-disable planes it's only possible to hit this
when racing multiple rmfb with fbdev restoring or similar evil things.
As long as userspace is nice it's impossible to hit the BUG_ON.
But the BUG_ON would most likely be hit from fbdev code, which usually
invovles the console_lock besides all modeset locks. So very likely
we'd never get the bug reports if this was hit in the wild, hence
better be safe than sorry and backport.

Commit 1da30627fc "drm: Add rotation value to
plane state" moved the rotation property to DRM core but only did the set
property part. This does the get property part as well.
