Backmerge tag 'v4.13-rc5' into drm-next
Linux 4.13-rc5
There's a really nasty nouveau collision, hopefully someone can take a look
once I pushed this out.
It's dead code, the core handles all this directly now.
The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.
v2: Rebase over the panel/brideg refactorings in stm/ltdc.

It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_helper_connector_set_property.
The only special case is nouveau which used one function for both
pre-nv50 legacy modeset code and post-nv50 atomic world instead of 2

What is rather strange here is how few drivers set this up, I suspect
the earlier patch to handle properties in the core did end up fixing a
pile of possible issues.

The driver stores lut values from the fbdev interface, and is able
to give them back, but does not appear to do anything with these
lut values. The generic fb helpers have replaced this function,
and may even have made the driver work for the C8 mode from the
fbdev interface. But that is untested.

The goal here was to minimise doing any thing or any check inside the
kernel that was not strictly required. For a userspace that assumes
complete control over the cache domains, the kernel is usually using
outdated information and may trigger clflushes where none were
required.
However, swapping is a situation where userspace has no knowledge of the
domain transfer, and will leave the object in the CPU cache. The kernel
must flush this out to the backing storage prior to use with the GPU. As
we use an asynchronous task tracked by an implicit fence for this, we
also need to cancel the ASYNC flag on the object so that the object will
wait for the clflush to complete before being executed. This also absolves
userspace of the responsibility imposed by commit 77ae995789 ("drm/i915:
Enable userspace to opt-out of implicit fencing") that its needed to ensure
that the object was out of the CPU cache prior to use on the GPU.

I was being overly paranoid in not updating the execobject.offset after
performing the fallback copy where we set reloc.presumed_offset to -1.
The thinking was to ensure that a subsequent NORELOC execbuf would be
forced to process the invalid relocations. However this is overkill so
long as we *only* update the execobject.offset following a successful
update of the relocation value witin the batch. If we have to repeat the
execbuf due to a later interruption, then we may skip the relocations on
the second pass (honouring NORELOC) since the execobject.offset match
the actual offsets (even though reloc.presumed_offset is garbage).
Subsequent calls to execbuf with NORELOC should themselves ensure that
the reloc.presumed_offset have been corrected in case of future
migration.
Reporting back the actual execobject.offset, even when
reloc.presumed_offset is garbage, ensures that reuse of those objects
use the latest information to avoid relocations.

The scaler allocation code depends on a non-zero default value for the
crtc scaler_id, so make sure we initialize the scaler state accordingly
even if the crtc is off. This fixes at least an initial YUV420 modeset
(added in a follow-up patchset by Shashank) when booting with the screen
off: after the initial HW readout and modeset which enables the scaler a
subsequent modeset will disable the scaler which isn't properly
allocated. This results in a funky HW state where the pipe scaler HW
registers can't be modified and the normally black screen is grey and
shifted to the right or jitters.
The problem was revealed by Shashank's YUV420 patchset and first
reported by Ville.

Taking the modeset locks unconditionally isn't the greatest idea,
because atm that part is still broken and times out (and then atomic
keels over). And there's really no reason to do so, the old code
didn't do that either.
To make the patch a bit simpler let's also nuke 2 cases that are only
around for the old mmioflip paths. Atomic nonblocking workers will not
die (minus bugs) when a gpu reset happens.
And of course this doesn't fix any of the gpu reset vs. modeset
deadlock fun, but it at least stop modern CI machines from keeling
over all over the place for no reason at all.
And we still have the explicit testcases to run the fake gpu reset, so
coverage isn't that much worse.
v2: Split out additional changes on top, restrict this to purely reducing
the critical section of modeset locks.
v2: Review from Maarten
- update comments
- don't oops when state is NULL in intel_finish_reset, but try to at
least still drop locks properly. The hw is going to be toast anyway.

Turns out that just writing CURPOS isn't sufficient to move the cursor
on some platforms. My 830 works just fine, but eg. 945 and PNV don't.
On those platforms we need to arm even the CURPOS update with a
CURBASE write.
Even worse, a write to any of the cursor register apart from CURBASE
will cancel an already pending cursor update. So if we have armed a
CURCNTR/CURBASE update, a subsequent CURPOS write prior to vblank
would cancel that armed update. Thus we're left with a cursor that
doesn't appear to move, or even change shape.
Fix the problem by always performing the CURBASE write after a
CURPOS write. Bspec is somewhat unclear which platforms actually
require this CURBASE write and which don't. So to keep it simple
and to make sure we really fix the problem across all supported
devices, let's just perform the CURBASE write unconditionally.

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
the entire panic handling code in our fbdev emulation. We might
restore kms panic output, but not through the bazillion of legacy
code layers called fbdev/fbcon, there's just no way to make that
work safely.
- With the module check change FBINFO_DEFAULT is always 0, so can be
removed too.
That removes another change to cargo-cult stuff in kms drivers, yay!

Once the Windows guest is shutdown, the display pipe will be disabled
and intel_gvt_check_vblank_emulation will be called to check if the
vblank timer is turned off. Given the scenario of creating VM1 ,VM2,
destoying VM2 in current code, VM1 has pipe enabled and continues to
check VM2, the flag have_enabled_pipe is always false since all the VM2
pipes are disabled, so the vblank timer will be canceled and TDR happens
in Windows VM1 guest due to the vsync timeout.
In this patch the vblank timer will be never canceled once one pipe is
enabled.
v2:
- remove have_enabled_pipe flag and check pipe enabled directly. (Zhenyu)

HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).
This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.
This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.
In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
- VIC for 4K modes for HDMI 1.4 sinks
- S3D information for S3D modes
As CEA-861-F has already defined VICs for 4K videomodes, this
patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
until the mode is 3D.

earlier wrapper was converting u32 to fixed16 in 32 bit so we were

Commit 24f8e00a8a ("drm/i915: Prefer to report ENOMEM rather than
incur the oom for gfx allocations") has tried to remove disruptive OOM
killer because the userspace should be able to cope with allocation
failures.
At the time only __GFP_NORETRY could achieve that and it turned out that
this would fail the allocations just too easily. So "drm/i915: Remove
__GFP_NORETRY from our buffer allocator" removed it and hoped for a
better solution. __GFP_RETRY_MAYFAIL is that solution. It will keep
retrying the allocation until there is no more progress and we would go
OOM. Instead we fail the allocation and let the caller to deal with it.

Paulo had noticed that inside cnl_ddi_vswing_program
the case was handling voltage but with no indication
of type where a missing type could also take us to that
path. So my first attempt was to add a message to
let clear who trigger that path.
However DK had a better idea that is to handle the
missed type sooner before it might take to that path.
So this v2 here uses his approach.
v2: Handle missed type sooner.
