While introducing HDMI support, component matching on connectors node
were bypassed since no driver would actually bind on the DT node.
But when only a CVBS connector is present, only a single node is found
in the graph, but ignored and a NULL match table is given to the
component code.
This code permits bypassing the components framework by binding directly
the DRM driver when no components needs to be loaded.

The scanline counter is bonkers on VLV/CHV DSI. The scanline counter
increment is not lined up with the start of vblank like it is on
every other platform and output type. This causes problems for
both the vblank timestamping and atomic update vblank evasion.
On my FFRD8 machine at least, the scanline counter increment
happens about 1/3 of a scanline ahead of the start of vblank (which
is where all register latching happens still). That means we can't
trust the scanline counter to tell us whether we're in vblank or not
while we're on that particular line. In order to keep vblank
timestamping in working condition when called from the vblank irq,
we'll leave scanline_offset at one, which means that the entire
line containing the start of vblank is considered to be inside
the vblank.
For the vblank evasion we'll need to consider that entire line
to be bad, since we can't tell whether the registers already
got latched or not. And we can't actually use the start of vblank
interrupt to get us past that line as the interrupt would fire
too soon, and then we'd up waiting for the next start of vblank
instead. One way around that would using the frame start
interrupt instead since that wouldn't fire until the next
scanline, but that would require some bigger changes in the
interrupt code. So for simplicity we'll just poll until we get
past the bad line.

Commit 7c3f86b6dc51 ("drm/i915: Invalidate the guc ggtt TLB upon
insertion") added the restoration of the invalidation routine after the
GuC was disabled, but missed that the GuC was unconditionally disabled
when not used. This then overwrites the invalidate routine for the older
chipsets, causing havoc and breaking resume as the most obvious victim.
We place the guard inside i915_ggtt_disable_guc() to be backport
friendly (the bug was introduced into v4.11) but it would be preferred
to be in more control over when this was guard (i.e. do not try and
teardown the data structures before we have enabled them). That should
be true with the reorganisation of the guc loaders.

commit bac2a909a096c9110525c18cbb8ce73c660d5f71

PCI / PM: Avoid resuming PCI devices during system suspend
PCI devices will default to allowing the system suspend complete
optimization where devices are not woken up during system suspend if
they were already runtime suspended. This however breaks the i915/HDA
drivers for two reasons:
- The i915 driver has system suspend specific steps that it needs to
run, that bring the device to a different state than its runtime
suspended state.
- The HDA driver's suspend handler requires power that it will request
from the i915 driver's power domain handler. This in turn requires the
i915 driver to runtime resume itself, but this won't be possible if the
suspend complete optimization is in effect: in this case the i915
runtime PM is disabled and trying to get an RPM reference returns
-EACCESS.
Solve this by requiring the PCI/PM core to resume the device during
system suspend which in effect disables the suspend complete optimization.
Regardless of the above commit the optimization stayed disabled for DRM
devices until
commit d14d2a8453d650bea32a1c5271af1458cd283a0f
Author: Lukas Wunner <lukas@wunner.de>
Date: Wed Jun 8 12:49:29 2016 +0200
drm: Remove dev_pm_ops from drm_class
so this patch is in practice a fix for this commit. Another reason for
the bug staying hidden for so long is that the optimization for a device
is disabled if it's disabled for any of its children devices. i915 may
have a backlight device as its child which doesn't support runtime PM
and so doesn't allow the optimization either. So if this backlight
device got registered the bug stayed hidden.
Credits to Marta, Tomi and David who enabled pstore logging,
that caught one instance of this issue across a suspend/
resume-to-ram and Ville who rememberd that the optimization was enabled
for some devices at one point.

Allow intel_engine_is_idle() to be called outside of the GT wakeref by
acquiring the device runtime pm for ourselves. This allows the function
to act as check after we assume the engine is idle and we release the GT
wakeref held whilst we have requests. At the moment, we do not call it
outside of an awake context but taking the wakeref as required makes it
more convenient to use for quick debugging in future.

The previous attempt at this had an issue with with num_clips > 1
because it would always end up using the coordinates of the last
clip while using width and height calculated from the bounding
box of all the clips.
So if the last clip happens to be not at the top-left corner of
the bounding box, the CPU blit operation would go out of bounds.
The original intent was to coalesce all the clips into one blit,
and to do that we need to also track the starting point of the
content buffer.

When vmw_gb_surface_define_ioctl() is called with an existing buffer,
we end up returning an uninitialized variable in the backup_handle.
The fix is to first initialize backup_handle to 0 just to be sure, and
second, when a user-provided buffer is found, we will use the
req->buffer_handle as the backup_handle.

BXT has a H/W issue with IOMMU which can lead to system hangs when
Aperture accesses are queued within the GAM behind GTT Accesses.
This patch avoids the condition by wrapping all GTT updates in stop_machine
and using a flushing read prior to restarting the machine.
The stop_machine guarantees no new Aperture accesses can begin while
the PTE writes are being emmitted. The flushing read ensures that
any following Aperture accesses cannot begin until the PTE writes
have been cleared out of the GAM's fifo.
Only FOLLOWING Aperture accesses need to be separated from in flight
PTE updates. PTE Writes may follow tightly behind already in flight
Aperture accesses, so no flushing read is required at the start of
a PTE update sequence.
This issue was reproduced by running
igt/gem_readwrite and
igt/gem_render_copy
simultaneously from different processes, each in a tight loop,
with INTEL_IOMMU enabled.
This patch was originally published as:
drm/i915: Serialize GTT Updates on BXT
[Note: This will cause a performance penalty for some use cases, but
avoiding hangs trumps performance hits. This may need to be worked
around in Mesa to recover the lost performance.]
v2: Move bxt/iommu detection into static function
Remove #ifdef CONFIG_INTEL_IOMMU protection
Make function names more reflective of purpose
Move flushing read into static function
v3: Tidy up for checkpatch.pl

Instead of taking the first pipe and giving the rest to kfd, take the
first 2 queues of each pipe.
Effectively, amdgpu and amdkfd own the same number of queues. But
because the queues are spread over multiple pipes the hardware will be
able to better handle concurrent compute workloads.
amdgpu goes from 1 pipe to 4 pipes, i.e. from 1 compute threads to 4
amdkfd goes from 3 pipe to 4 pipes, i.e. from 3 compute threads to 4
