These exist to give NVKM information on the set of display paths that
the DD needs to be active at any given time.
Previously, the supervisor attempted to determine this solely from OR
state, but there's a few configurations where this information on its
own isn't enough to determine the specific display paths in question:
- ANX9805, where the PIOR protocol for both DP and TMDS is TMDS.
- On a device using DCB Switched Outputs.
- On GM20x and newer, with a crossbar between the SOR and macro links.
After this commit, the DD tells NVKM *exactly* which display path it's
attempting a modeset on.

Enable stereoscopic output for HDMI and DisplayPort connectors on

hardware in case there is some older board that still has HDMI
output but for which we have no logic for setting the Vendor

drm_mode_set_crtcinfo() does compensation for interlace and
doublescan timing effects already, so do it first and use the
compensated figures instead of the constant "vscan / ilace" terms
that we had before.
And then it turns out that the hardware model for how the timing
parameters are configured is basically the standard model, but
starting one clock before the sync pulse rather than at the start
of the display area, which lets us drastically simplify the
overall timing calculations (verifying the changes by algebraic
operations is left as an exercise for the reader).
Finally, there were a couple of issues with the computation of
m->v.blankus that are addressed here. Interlaced modes would
generate a negative intermediate result. Double scan modes would
generate an overestimate rather than an underestimate. And when
enabling frame-packing modes, a rather extreme overestimate would
be generated. Fixed, by using the timings as adjusted for the
CRTC to find the length of the vertical blanking period instead of
mixing adjusted and pre-adjustment timing parameters.

Backmerge tag 'v4.12-rc3' into drm-next

Daniel has requested this for some drm-intel-next work.
Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI
as a convenience.
Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
through the atomic API, but realizing that userspace is likely to take
shortcuts and assume that the enum values are what is sent over the
wire.
As a result these defines are provided purely as a convenience to
userspace applications.
Changes since v3:
- Switched away from past tense in comments
- Add define name change to previously mis-spelled DRM_REFLECT_X comment
- Improved the comment for the DRM_MODE_REFLECT_<axis> comment
Changes since v2:
- Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_
- Fix compilation errors
- Changed comment formatting
- Deduplicated comment lines
- Clarified DRM_MODE_PROP_REFLECT_ comment
Changes since v1:
- Moved defines from drm.h to drm_mode.h
- Changed define prefix from DRM_ to DRM_MODE_PROP_
- Updated uses of the defines to the new prefix
- Removed include from drm_rect.c

Commit cae9ff036e effectively disabled the drm poll_helper by checking
the wrong flag to see if the driver should enable the poll or not:
mode_config.poll_enabled is only set to true by poll_init and it is not
indicating if the poll is enabled or not.
nouveau_display_create() will initialize the poll and going to disable it
right away. After poll_init() the mode_config.poll_enabled will be true,
but the poll itself is disabled.
To avoid the race caused by calling the poll_enable() from different paths,
this patch will enable the poll from one place, in the
nouveau_display_hpd_work().
In case the pm_runtime is disabled we will enable the poll in
nouveau_drm_load() once.

Quite a few patches, but not much code changed:
- Fixes regression from atomic when only the source rect of a plane
changes (ie. xrandr --right-of)
- Fixes another issue where atomic changed behaviour underneath us,
potentially causing laggy cursor position updates
- Fixes for a bunch of races in thermal code, which lead to random
lockups for a lot of users

drm/nouveau/therm: remove ineffective workarounds for alarm bugs
drm/nouveau/tmr: avoid processing completed alarms when adding a new one
drm/nouveau/tmr: fix corruption of the pending list when rescheduling an alarm
drm/nouveau/tmr: handle races with hw when updating the next alarm time
drm/nouveau/tmr: ack interrupt before processing alarms
drm/nouveau/core: fix static checker warning
drm/nouveau/fb/ram/gf100-: remove 0x10f200 read
drm/nouveau/kms/nv50: skip core channel cursor update on position-only changes
drm/nouveau/kms/nv50: fix source-rect-only plane updates
drm/nouveau/kms/nv50: remove pointless argument to window atomic_check_acquire()
These were ineffective due to touching the list without the alarm lock,
but should no longer be required.

The idea here was to avoid having to "manually" program the HW if there's
a new earliest alarm. This was lazy and bad, as it leads to loads of fun
races between inter-related callers (ie. therm).
Turns out, it's not so difficult after all. Go figure ;)

At least therm/fantog "attempts" to work around this issue, which could
lead to corruption of the pending alarm list.
Fix it properly by not updating the timestamp without the lock held, or
trying to add an already pending alarm to the pending alarm list....

If the time to the next alarm is short enough, we could race with HW and
end up with an ~4 second delay until it triggers.
Fix this by checking again after we update HW.

Fixes a race where we can miss an alarm that triggers while we're already
processing previous alarms.

object->engine cannot be NULL, it's either valid, or an error pointer.
This particular condition shouldn't actually be possible, but just in
case, we'll keep it.

This reg has moved on Pascal, and causes a bus fault.
We never use the value anyway, so just remove the read.

The DRM core used to only call prepare_fb/cleanup_fb() when a plane's
framebuffer changed, which achieved the desired effect.
It's apparently now up to the driver to decide on its own.

This "optimisation" (which was originally meant to skip updating cursor
settings in the core channel on position-only updates) turned out to be
pointless in the final design of the code before it was merged.
Remove it completely, as it breaks other cases.
