When fb is tiled and fb->height isn't the multiple of tile's height,
the format fb->size = fb->stride * fb->height, will get a smaller size
than the actual size. As the memory height of tiled fb should be multiple
of tile's height.

Commit 7769db588384 ("drm/i915/dp: optimize eDP 1.4+ link config fast
and narrow") started to optize the eDP 1.4+ link config, both per spec
and as preparation for display stream compression support.
Sadly, we again face panels that flat out fail with parameters they
claim to support. Revert, and go back to the drawing board.
v2: Actually revert to max params instead of just wide-and-slow.

Push getting the reference for the encoders' power domains into the
encoder get_power_domains() hook instead of doing this from the caller.
This way the encoder can store away the corresponding wakerefs.
This fixes the DSI encoder disabling, which didn't release these
power references it acquired during HW state readout.
Note that longtime ownership for the corresponding wakerefs can be thus
acquired / released in two ways. Nevertheless there is always only one
owner for them:
After HW readout (booting/system resume):
- encoder->get_power_domains() acquires
- encoder->disable*() releases
After a modeset (calling intel_atomic_commit()):
- encoder->enable*() acquires
- encoder->disable*() releases
* can be any of the encoder enable/disable hooks.
v2:
- Check that the DSI io_wakerefs are unset both during encoder HW
readout and enabling. (Chris)

The only bpc information in pipe registers for BXT/GLK DSI
is the PIPEMISC dither bpc. Let's try to use that to read
out pipe_bpp on these platforms. However, I'm not sure if
this will be correctly populated by the GOP since bspec
suggests it's only needed if dithering is actually enabled.
If not I guess we'll have to go one step further and
extract pipe_bpp from the DSI pixel format when dithering
is disabled.

ppgtt_free_all_spt() iterates the radixtree as it is deleting it,
forgoing all protection against the leaves being freed in the process
(leaving the iter pointing into the void).
A minimal fix seems to be to use the available post_shadow_list to
decompose the tree into a list prior to destroying the radixtree.
Alerted by the sparse warnings:

shadow mm's pin count got increased in workload preparation phase, which
is after workload scanning.
it will get decreased in complete_current_workload() anyway after
workload completion.
Sometimes, if a workload meets a scanning error, its shadow mm pin count
will not get increased but will get decreased in the end.
This patch lets shadow mm's pin count not go below 0.

If I'm reading the spec right AML 0x87CA is a Y SKU, so it
should be marked as ULX in our old style terminology.

We assumed that vm_mmap() would reject an attempt to mmap past the end of
the filp (our object), but we were wrong.
Applications that tried to use the mmap beyond the end of the object
would be greeted by a SIGBUS. After this patch, those applications will
be told about the error on creating the mmap, rather than at a random
moment on later access.

We rely on VBT DDI port info for eDP detection on GEN9 platforms and
above. This breaks GEN9 platforms which don't have VBT because port A
eDP now defaults to false. Fix this by defaulting to true when VBT is
missing.

We may race the interrupt signaling with retirement, in which case the
order in which we acquire the reference inside the interrupt is vital to
provide the correct barrier against the request being freed in
retirement, i.e. we need to acquire our reference before marking the
breadcrumb as cancelled (as soon as the breadcrumb is cancelled
retirement may drop its reference to the request without serialisation
with the interrupt handler).

If we drop the engine lock, we may run execlists_dequeue which may free
the priolist. Therefore if we ever drop the execution lock on the
engine, we have to discard our cache and refetch the priolist to ensure
we do not use a stale pointer.

If we allocate while iterating the rbtree of active nodes, we may hit
the shrinker and so retire the i915_active, reaping the rbtree. Modifying
the rbtree as we iterate is not good behaviour, so acquire the
i915_active first to keep the tree intact whenever we allocate.

The downgrade of the fullmodeset into fastset
intel_encoder->update_pipe, in possible scenario, skips the En/Dis-able
DDI. Hence breaks the HDCP state change handling.
We also don't have any hdcp tests in CI, because the shard runs don't
have hdcp capable outputs :-/
So this change fixs it by handling the HDCP state change request at
intel_encoder->update_pipe too along with enable and disable of the DDI.
Fixes: d19f958db23c ("drm/i915: Enable fastset for non-boot modesets.")
v2:

Pull char/misc driver updates from Greg KH:
"Here is the big char/misc driver patch pull request for 5.1-rc1.
The largest thing by far is the new habanalabs driver for their AI
accelerator chip. For now it is in the drivers/misc directory but will
probably move to a new directory soon along with other drivers of this
type.
Other than that, just the usual set of individual driver updates and
fixes. There's an "odd" merge in here from the DRM tree that they
asked me to do as the MEI driver is starting to interact with the i915
driver, and it needed some coordination. All of those patches have
been properly acked by the relevant subsystem maintainers.
All of these have been in linux-next with no reported issues, most for
quite some time"

The migration scanner is a linear scan of a zone with a potentiall large
search space. Furthermore, many pageblocks are unusable such as those
filled with reserved pages or partially filled with pages that cannot
migrate. These still get scanned in the common case of allocating a THP
and the cost accumulates.
The patch uses a partial search of the free lists to locate a migration
source candidate that is marked as MOVABLE when allocating a THP. It
prefers picking a block with a larger number of free pages already on
the basis that there are fewer pages to migrate to free the entire
block. The lowest PFN found during searches is tracked as the basis of
the start for the linear search after the first search of the free list
fails. After the search, the free list is shuffled so that the next
search will not encounter the same page. If the search fails then the
subsequent searches will be shorter and the linear scanner is used.
If this search fails, or if the request is for a small or
unmovable/reclaimable allocation then the linear scanner is still used.
It is somewhat pointless to use the list search in those cases. Small
free pages must be used for the search and there is no guarantee that
movable pages are located within that block that are contiguous.

This shows an improvement in allocation latencies with similar
allocation success rates. While not presented, there was a 31%
reduction in migration scanning and a 8% reduction on system CPU usage.
A 2-socket machine showed similar benefits.

As vGPU shadow ctx is loaded with guest context state, arbitrarily
submitting request in error workload dispatch path would cause trouble.
So don't try to submit in error path now like in previous code.
This is to fix VM failure when GPU hang happens.

There is one corner case that workload_thread may pick and dispatch one
workload of vgpu after it's already deactivated. Below is the scenario:
1. deactive_vgpu got the vgpu_lock, it found pending workload was
submitted, then it released the vgpu_lock and wait for vgpu idle.
2. before deactive_vgpu got the vgpu_lock back, workload_thread might pick
one new valid workload, then it was blocked by the vgpu_lock.
3. deactive_vgpu got the vgpu_lock again, finished the last processes of
deactivating, then release the vgpu_lock.
4. workload_thread got the vgpu_lock, then it will try to dispatch the
fetched workload. It's not expected one workload of deactivated vgpu is
dispatched.
The solution is to add condition check of the vgpu's active flag and stop
to schedule when it's inactive.

Depends on GEN family and I915_PARAM_HAS_CONTEXT_ISOLATION, Mesa driver
will decide whether constant buffer 0 address is relative or absolute,
and load GPU initial state by lri to context mmio INSTPM (GEN8)
or 0x20D8 (>=GEN9).
Mesa Commit fa8a764b62
("i965: Use absolute addressing for constant buffer 0 on Kernel 4.16+.")
INSTPM is already added to gen8_engine_mmio_list, but 0x20D8 is missed
in gen9_engine_mmio_list. From GVT point of view, different guest could
have different context so should switch those mmio accordingly.

When MI_FLUSH_DW post write hw status page in index mode, the index
value is in dword step and turned into address offset in cmd dword1.
As status page size is 4K, so can't exceed that.
This fixed upper bound check in cmd parser code which incorrectly
stopped VM for reason of invalid MI_FLUSH_DW write index.
v2:
- Fix upper bound as 4K page size because index value is address offset.
