drm/imx: fix YUV primary plane and IPUv3 build corner case
- Enable color space conversion on the primary plane when the framebuffer
format is a YUV format.
- The IPUv3 base driver now uses drm_format_info in the PRE/PRG code. The
PRE/PRG parts are already disabled if DRM is not available. Enforce that
if DRM is built as a module, IPUv3 must be built as a module, too.

Final pile of features for 4.14
- New ioctl to change NOA configurations, plus prep (Lionel)
- CCS (color compression) scanout support, based on the fancy new
modifier additions (Ville&Ben)
- Document i915 register macro style (Jani)
- Many more gen10/cnl patches (Rodrigo, Pualo, ...)
- More gpu reset vs. modeset duct-tape to restore the old way.
- prep work for cnl: hpd_pin reorg (Rodrigo), support for more power
wells (Imre), i2c pin reorg (Anusha)
- drm_syncobj support (Jason Ekstrand)
- forcewake vs gpu reset fix (Chris)
- execbuf speedup for the no-relocs fastpath, anv/vk low-overhead ftw (Chris)
- switch to idr/radixtree instead of the resizing ht for execbuf id->vma
lookups (Chris)
gvt:
- MMIO save/restore optimization (Changbin)
- Split workload scan vs. dispatch for more parallel exec (Ping)
- vGPU full 48bit ppgtt support (Joonas, Tina)
- vGPU hw id expose for perf (Zhenyu)
Bunch of work all over to make the igt CI runs more complete/stable.
Watch https://intel-gfx-ci.01.org/tree/drm-tip/shards-all.html for
progress in getting this ready. Next week we're going into production
mode (i.e. will send results to intel-gfx) on hsw, more platforms to

During a global reset, we disable the irq. As we disable the irq, the
hardware may be raising a GT interrupt that we then ignore, leaving it
pending in the GTIIR. After the reset, we then re-enable the irq,
triggering the pending interrupt. However, that interrupt was for the
stale state from before the reset, and the contents of the CSB buffer
are now invalid.
v2: Add a comment to make it clear that the double clear is purely my
paranoia.

The commit 213e08ad60ba
("drm/i915/bxt: add bxt dsi gpio element support")
enables GPIO support for Broxton based platforms.
While using that API we might get into troubles in the future, because
we can't rely on label name in the driver since vendor firmware might
provide any GPIO pin there, e.g. "reset", and even mark it in _DSD (in
which case the request will fail).
To avoid inconsistency and potential issues we have two options:
a) generate GPIO ACPI mapping table and supply it via
acpi_dev_add_driver_gpios(), or
b) just pass NULL as connection ID.
The b) approach is much simpler and would work since the driver relies
on GPIO indices only. Moreover, the _CRS fallback mechanism, when
requesting GPIO, has been made stricter, and supplying non-NULL
connection ID when neither _DSD, nor GPIO ACPI mapping is present, is
making request fail.

drm-next
this cycle has been fairly calm in etnaviv land with most of the action
happening on the userspace side.
Notable changes:
- Improvements to CONFIG option handling to make it harder for users to
shoot themselves in the foot due to kernel misconfiguration.
- Tweaked GEM object population, so that userspace can take considerate
action when memory allocation fails, rather than waking the raging OOM
killer beast.

This is the amdkfd pull request for 4.14 merge window.
AMD has started cleaning the pipe and sending patches from their internal
development to the upstream community.
The plan as I understand it is to first get all the non-dGPU patches to
upstream and then move to upstream dGPU support.
The patches here are relevant only for Kaveri and Carrizo.
The following is a summary of the changes:
- Add new IOCTL to set a Scratch memory VA
- Update PM4 headers for new firmware that support scratch memory
- Support image tiling mode
- Remove all uses of BUG_ON
- Various Bug fixes and coding style fixes

In a synchronous setup, we may retire the last request before we
complete allocating the next request. As the last request is retired, we
queue a timer to mark the device as idle, and promptly have to execute
ad cancel that timer once we complete allocating the request and need to
keep the device awake. If we rearrange the mark_busy() to occur before
we retire the previous request, we can skip this ping-pong.
v2: Joonas pointed out that unreserve_seqno() was now doing more than
doing seqno handling and should be renamed to reflect its wider purpose.
That also highlighted the new asymmetry with reserve_seqno(), so fixup
that and rename both to [un]reserve_engine().

This was the competing idea long ago, but it was only with the rewrite
of the idr as an radixtree and using the radixtree directly ourselves,
along with the realisation that we can store the vma directly in the
radixtree and only need a list for the reverse mapping, that made the
patch performant enough to displace using a hashtable. Though the vma ht
is fast and doesn't require any extra allocation (as we can embed the node
inside the vma), it does require a thread for resizing and serialization
and will have the occasional slow lookup. That is hairy enough to
investigate alternatives and favour them if equivalent in peak performance.
One advantage of allocating an indirection entry is that we can support a
single shared bo between many clients, something that was done on a
first-come first-serve basis for shared GGTT vma previously. To offset
the extra allocations, we create yet another kmem_cache for them.

When userspace is doing most of the work, avoiding relocs (using
NO_RELOC) and opting out of implicit synchronisation (using ASYNC), we
still spend a lot of time processing the arrays in execbuf, even though
we now should have nothing to do most of the time. One issue that
becomes readily apparent in profiling anv is that iterating over the
large execobj[] is unfriendly to the loop prefetchers of the CPU and it
much prefers iterating over a pair of arrays rather than one big array.

Forcewake is not affected by the engine reset on gen6+. Indeed the
reason why we added intel_uncore_forcewake_reset() to
gen6_reset_engines() was to keep the bookkeeping intact because the
reset did not touch the forcewake bit (yet we cancelled the forcewake
consumers)! This was done in commit 521198a2e7095:
Author: Mika Kuoppala <mika.kuoppala@linux.intel.com>
Date: Fri Aug 23 16:52:30 2013 +0300
drm/i915: sanitize forcewake registers on reset
In reset we try to restore the forcewake state to
pre reset state, using forcewake_count. The reset
doesn't seem to clear the forcewake bits so we
get warn on forcewake ack register not clearing.
That futzing of the forcewake bookkeeping was dropped in commit
0294ae7b44bb ("drm/i915: Consolidate forcewake resetting to a single
function"), but it did not make the realisation that the remaining
intel_uncore_forcewake_reset() was redundant.
The new danger with using intel_uncore_forcewake_reset() with per-engine
resets is that the driver and hw are still in an active state as we
perform the reset. We may be using the forcewake to read protected
registers elsewhere and those results may be clobbered by the concurrent
dropping of forcewake.

and BXT. Rename i915_port_to_ to g4x_port_to since that was
the first platform to run this. Correct code style. (Paulo)

This should save us a bunch of command submission overhead.
v2: move the LRU move to the right place to avoid the move for the root BO

the move needs to happen before the kmap.
