In order to avoid accessing GPU registers while GPU is suspended cancel
the hangcheck work before calling intel_suspend_complete which actually
puts the GPU to suspend. Otherwise hangcheck might do MMIO reads to a
suspended GPU.
Placement before intel_guc_suspend is imitated from i915_drm_suspend
which cancels the work at i915_gem_suspend, to keep the functions
similar.
On VLV systems, namely BYT, this was causing an error during runtime
suspend cycle:

This adds code to initialise the SDP streams
for a sink in the simplest ordering.
I've no idea how you'd want to control the

All of these iterator macros require a 'temp' argument, used merely to
hold internal partial results. We can instead declare the temporary
variable inside the macro, so the caller need not provide it.
Some of the old code contained nested iterators that actually reused the
same 'temp' variable for both inner and outer instances. It's quite
surprising that this didn't introduce bugs! But it does show that the
value of 'temp' isn't required to persist during the iterated body.

Userspace can pass in an offset that it presumes the object is located
at. The kernel will then do its utmost to fit the object into that
location. The assumption is that userspace is handling its own object
locations (for example along with full-ppgtt) and that the kernel will
rarely have to make space for the user's requests.

v2: Fixed incorrect eviction found by Michal Winiarski - fix suggested by Chris
Wilson. Fixed incorrect error paths causing crash found by Michal Winiarski.
(Not published externally)
v3: Rebased because of trivial conflict in object_bind_to_vm. Fixed eviction
to allow eviction of soft-pinned objects when another soft-pinned object used
by a subsequent execbuffer overlaps reported by Michal Winiarski.
(Not published externally)
v4: Moved soft-pinned objects to the front of ordered_vmas so that they are
pinned first after an address conflict happens to avoid repeated conflicts in
rare cases (Suggested by Chris Wilson). Expanded comment on
drm_i915_gem_exec_object2.offset to cover this new API.
v5: Added I915_PARAM_HAS_EXEC_SOFTPIN parameter for detecting this capability
(Kristian). Added check for multiple pinnings on eviction (Akash). Made sure
buffers are not considered misplaced without the user specifying
EXEC_OBJECT_SUPPORTS_48B_ADDRESS. User must assume responsibility for any
addressing workarounds. Updated object2.offset field comment again to clarify
NO_RELOC case (Chris). checkpatch cleanup.
v6: Trivial rebase on latest drm-intel-nightly
v7: Catch attempts to pin above the max virtual address size and return
EINVAL (Tvrtko). Decouple EXEC_OBJECT_SUPPORTS_48B_ADDRESS and
EXEC_OBJECT_PINNED flags, user must pass both flags in any attempt to pin
something at an offset above 4GB (Chris, Daniel Vetter).

As described in the code comment, I couldn't set the minimum RPS
frequency on my BYT-M B0 to the minimum allowed as reported by Punit.
Fix this by clamping the minimum value to the first one that was
accepted on my machine.
Atm this issue doesn't cause any test failures, since in igt/pm_rps we
only check the cached version of the current frequency which is the same
what has been set. In the future we'll add checks for the actual
frequency too, and for that to pass this fix is necessary.

Currently we have 4 helper libraries (probe, crtc, plane & atomic)
that all use the same helper vtables. And that's by necessity since we
don't want to litter the core structs with one ops pointer per helper
library. Also often the reuse the same hooks (like atomic does, to
facilite conversion from existing drivers using crtc and plane
helpers).
Given all that it doesn't make sense to put the docs for these next to
specific helpers. Instead extract them into a new header file and
section in the docbook, and add references to them everywhere.
Unfortunately kernel-doc complains when an include directive doesn't
find anything (and it does by dumping crap into the output file). We
have to remove the now empty includes to avoid that, instead of leaving
them in for future proofing.

Currently we disable some parts of FDI setup after a failed link
training. But despite that we continue with the modeset as if everything
is fine. This results in tons of noise from the state checker, and
it means we're not following the proper modeset sequence for the rest of
crtc enabling, nor for crtc disabling.
Ideally we should abort the modeset and follow the proper disable
sequence to shut off everything we enabled so far, but that would
require a big rework of the modeset code. So instead just leave FDI
up and running in its untrained state, and log an error. This is
what we do on older platforms too.

Bspec modeset sequence tells us to disable the PCH transcoder and
FDI after the CRT port on LPT-H, so let's do that. And the CRT port
should be disabled after the pipe, as we do on other PCH platforms
too since
commit 1ea56e269e13 ("drm/i915: Disable CRT port after pipe on PCH platforms")
commit 00490c22b1b5 ("drm/i915: Consider SPLL as another shared pll, v2.")
moved the SPLL disable from the .post_disable() hook to some upper
level code, so we can just move the CRT port disabling into the
.post_disable() hook. If we still had the non-shared SPLL, it would have
needed to be moved into the .post_pll_disable() hook.

When we want to use SPLL for FDI we want SSC, which means we have to
disable clock bending for the PCH SSC reference (bend and spread are
mutually exclusive). So let's turn off bending when we want spread.
In case the BIOS enabled clock bending for some reason we'll just turn
it off and enable the spread mode instead.
Not sure what happens if the BIOS is actually using the bend source for
HDMI at this time, but I suppose it should be no worse than what already
happens when we simply turn on the spread.
We don't currently use the bend source for anything, and only use the
PCH SSC reference for the SPLL to drive FDI (always with spread).

There is conflicting info between E0 and F0 steppings
for this workarounds. Trust more authoritative source and
be conservative and extend also for F0.
This prevents numerous (>50) gpu hangs with SKL GT4e
during piglit run.

Fixes native drm clients like Fedora 23 Wayland which now appears to
be able to use cursor hotspots without strange cursor offsets.
Also fixes a couple of ignored error paths.
Since the core drm cursor hotspot is incompatible with the legacy vmwgfx
hotspot (the core drm hotspot is reset when the drm_mode_cursor ioctl
is used), we need to keep track of both and add them when the device
hotspot is set. We assume that either is always zero.

drm/i915: Clean up associated VMAs on context destruction
Added a warning based on an incorrect assumption that all VMAs
in a VM will be on the inactive list at the point last reference
to a context and VM is dropped.
This is not true because i915_gem_object_retire__read will not
put VMA on the inactive list until all activities on the object
in question (in all VMs) have been retired.
As a consequence, whether or not a context/VM will be destroyed
with its VMAs still on the active list, can depend on completely
unrelated activities using the same object from a different
context or engine.

An async pageflip stores the modeset to be done and executes it once
the BOs are ready to be displayed. This gets us about 3x performance
in full screen rendering with pageflipping.

The user submission is basically a pointer to a command list and a
pointer to uniforms. We copy those in to the kernel, validate and
relocate them, and store the result in a GPU BO which we queue for
execution.
v2: Drop support for NV shader recs (not necessary for GL), simplify
vc4_use_bo(), improve bin flush/semaphore checks, use __u32 style
types.
