drm/i915: SAGV is not SKL-only, so rename a few things
The plan is to introduce intel_has_sagv() and then use it to discover
which platforms actually support it.
I thought about keeping the functions with their current skl names,
but found two problems: (i) skl_has_sagv() would become a very
confusing name, and (ii) intel_atomic_commit_tail() doesn't seem to be
calling any functions whose name start with a platform name, so the
"intel_" naming scheme seems make more sense than the "firstplatorm_"
naming scheme here.

drm/i915: don't forget to set intel_crtc->dspaddr_offset on SKL+
We never remembered to set it (so it was zero), but this was not a
problem in the past due to the way handled the hardware registers.
Unfortunately we changed how we set the hardware and forgot to set
intel_crtc->dspaddr_offset.
This started to reflect on a few kms_frontbuffer_tracking subtests
that relied on page flips with CRTCs that don't point to the x:0,y:0
coordinates of the frontbuffer. After the page flip the CRTC was
showing the x:0,y:0 coordinate of the frontbuffer instead of
x:500,y:500. This problem is present even if we don't enable FBC or
PSR.
While trying to bisect it I realized that the first bad commit
actually just gives me a black screen for the mentioned tests instead
of showing the wrong x:0,y:0 offsets. A few commits later the black
screen problem goes away and we get to the point where the code is
today, but I'll consider the black screen as the first bad commit
since it's the point where the IGT subtests start to fail.

drm/radeon: Prevent races on pre DCE4 between flip submission and completion.
Pre DCE4 hw doesn't have reliable pageflip completion
interrupts, so instead polling for flip completion is
used from within the vblank irq handler to complete
page flips.
This causes a race if pageflip ioctl is called close to
vblank:
1. pageflip ioctl queues execution of radeon_flip_work_func.
2. vblank irq fires, radeon_crtc_handle_vblank checks for
flip_status == FLIP_SUBMITTED finds none, no-ops.
3. radeon_flip_work_func runs inside vblank, decides to
set flip_status == FLIP_SUBMITTED and programs the
flip into hw.
4. hw executes flip immediately (because in vblank), but
as 2 already happened, the flip completion routine only
emits the flip completion event one refresh later ->
wrong vblank count/timestamp for completion and no
performance gain, as instead of delaying the flip until
next vblank, we now delay the next flip by 1 refresh
while waiting for the delayed flip completion event.
Given we often don't gain anything due to this race, but
lose precision, prevent the programmed flip from executing
in vblank on pre DCE4 asics to avoid this race.
On pre-AVIVO hw we can't program the hw for edge-triggered
flips, they always execute anywhere in vblank. Therefore delay
the actual flip programming until after vblank on pre-AVIVO.

drm/radeon: Slightly more robust flip completion handling for < DCE-4
Pre DCE4 hardware doesn't have (reliable) pageflip completion
irqs, therefore we have to use the old polling method for flip
completion handling in vblank irq.
As vblank irqs fire a bit before start of vblank (when the
linebuffer fifo read position reaches end of scanout), we
have some fudge for flip completion handling in the last
lines of active scanout. Old code assumed the threshold to
be 99% of active scanout height, a ballpark estimate which
worked ok. Since we know since a while how to calculate the
actual threshold from linebuffer size, lets make use of it
to get a more accurate threshold.
This completion path is still prone to some races in corner
cases, especially on pre-AVIVO hardware, so document them
a bit better in the code comments.

drm: Convert prime dma-buf <-> handle to rbtree
Currently we use a linear walk to lookup a handle and return a dma-buf,
and vice versa. A long overdue TODO task is to convert that to a
hashtable. Since the initial implementation of dma-buf/prime, we now
have resizeable hashtables we can use (and now a future task is to RCU
enable the lookup!). However, this patch opts to use an rbtree instead
to provide O(lgN) lookups (and insertion, deletion). rbtrees were chosen
over using the RCU backed resizable hashtable to firstly avoid the
reallocations (rbtrees can be embedded entirely within the parent
struct) and to favour simpler code with predictable worst case
behaviour. In simple testing, the difference between using the constant
lookup and insertion of the rhashtable and the rbtree was less than 10%
of the wall time (igt/benchmarks/prime_lookup) - both are dramatic
improvements over the existing linear lists.

drm: Restore lost drm_framebuffer_unreference in drm_mode_page_flip_ioctl

43968d7b806d ("drm: Extract drm_plane.[hc]") was not the simple

drm/exynos: g2d: use autosuspend mode for PM runtime
The runqueue worker currently issues a get() when a new
node is processed, and a put() once a node is completed.
The corresponding suspend and resume calls currently only
do clock gating, but with the upcoming introduction of
IOMMU runpm also the corresponding IOMMU domain gets
enabled (for get()) and disabled (for put()). This
introduces performance regressions with we mitigate here.
Switch PM runtime to autosuspend, such that clock gating
and IOMMU control only happens when the engine is idle for
a 'long' time.

While the engine works on a runqueue node it does memory access to

Make sure that the engine is idle when g2d_close() and/or
g2d_remove() are called, i.e. buffer associated with the process (for
g2d_close()), or all buffers (for g2d_remove()) can be safely be
unmapped.
We have to take into account that the engine might be in an undefined
state, i.e. it hangs and doesn't become idle. In this case, we issue
a hardware reset to return the hardware and the driver context into a
proper state.

This reverts commit
b05984e21a7e000bf5074ace00d7a574944b2c16.
The change, i.e. merging the sleep and runpm operations, produces
a deadlock situation:
(1) exynos_g2d_exec_ioctl() prepares a runqueue node and
calls g2d_exec_runqueue()
(2) g2d_exec_runqueue() calls g2d_dma_start() which gets
runtime PM sync
(3) runtime PM core calls g2d_runtime_resume()
(4) g2d_runtime_resume() calls g2d_exec_runqueue(), which
loops back to (2)
Due to mutexes that are in place, a deadlock situation is created.

Notable changes:
- Cleanups from Fabio to some error paths and proper error propagation.
- Lots of refactoring and new code to support the new MMU version 2,
still relatively unoptimized and doesn't yet provide better process
isolation than MMUv1, but enough to get newer cores up and running.
- New hardware support: GC3000, as found on the NXP i.MX6 QuadPlus SoC.
