These are some dodgy "convenience" macros for the DRM driver to peek
into NVKM state. They're still used in a few places, but don't belong
in nvif/device.h in any case.
Move them to nouveau_drv.h, and modify callers to pass a nouveau_drm
instead of an nvif_device.

TTM wants to get rid of the duplicate refcounting of the embedded GEM
object and its own reference count.
Hence, use of GEM object references where possible.
Also get rid of nouveau_bo_ref() and replace it with nouveau_bo_fini(),
which drops the initial reference we get from initializing a ttm_bo.

nouveau_fence_emit() can fail before and after initializing the
dma-fence and hence before and after initializing the dma-fence' kref.
In order to avoid nouveau_fence_emit() potentially failing before
dma-fence initialization pass the channel to nouveau_fence_new() already
and perform the required check before even allocating the fence.
While at it, restore the original behavior of nouveau_fence_new() and
add nouveau_fence_create() for separate (pre-)allocation instead. Always
splitting up allocation end emit wasn't a good idea in the first place.
Hence, limit it to the places where we actually need to pre-allocate.

The new (VM_BIND) UAPI exports DMA fences through DRM syncobjs. Hence,
in order to emit fences within DMA fence signalling critical sections
(e.g. as typically done in the DRM GPU schedulers run_job() callback) we
need to separate fence allocation and fence emitting.

Losing HW accelerated rendering isn't ideal, but it's been significantly
reduced in performance since the removal of accelerated scrolling in the
kernel anyway - not to mention, can be racey (skips cpu<->gpu sync) from
certain contexts.

This introduces support for CRC readback on gf119+, using the
documentation generously provided to us by Nvidia:
https://github.com/NVIDIA/open-gpu-doc/blob/master/Display-CRC/display-crc.txt
We expose all available CRC sources. SF, SOR, PIOR, and DAC are exposed
through a single set of "outp" sources: outp-active/auto for a CRC of
the scanout region, outp-complete for a CRC of both the scanout and
blanking/sync region combined, and outp-inactive for a CRC of only the
blanking/sync region. For each source, nouveau selects the appropriate
tap point based on the output path in use. We also expose an "rg"
source, which allows for capturing CRCs of the scanout raster before
it's encoded into a video signal in the output path. This tap point is
referred to as the raster generator.
Note that while there's some other neat features that can be used with
CRC capture on nvidia hardware, like capturing from two CRC sources
simultaneously, I couldn't see any usecase for them and did not
implement them.
Nvidia only allows for accessing CRCs through a shared DMA region that
we program through the core EVO/NvDisplay channel which is referred to
as the notifier context. The notifier context is limited to either 255
(for Fermi-Pascal) or 2047 (Volta+) entries to store CRCs in, and
unfortunately the hardware simply drops CRCs and reports an overflow
once all available entries in the notifier context are filled.
Since the DRM CRC API and igt-gpu-tools don't expect there to be a limit
on how many CRCs can be captured, we work around this in nouveau by
allocating two separate notifier contexts for each head instead of one.
We schedule a vblank worker ahead of time so that once we start getting
close to filling up all of the available entries in the notifier
context, we can swap the currently used notifier context out with
another pre-prepared notifier context in a manner similar to page
flipping.
Unfortunately, the hardware only allows us to this by flushing two
separate updates on the core channel: one to release the current
notifier context handle, and one to program the next notifier context's
handle. When the hardware processes the first update, the CRC for the
current frame is lost. However, the second update can be flushed
immediately without waiting for the first to complete so that CRC
generation resumes on the next frame. According to Nvidia's hardware
engineers, there isn't any cleaner way of flipping notifier contexts
that would avoid this.
Since using vblank workers to swap out the notifier context will ensure
we can usually flush both updates to hardware within the timespan of a
single frame, we can also ensure that there will only be exactly one
frame lost between the first and second update being executed by the
hardware. This gives us the guarantee that we're always correctly
matching each CRC entry with it's respective frame even after a context
flip. And since IGT will retrieve the CRC entry for a frame by waiting
until it receives a CRC for any subsequent frames, this doesn't cause an
issue with any tests and is much simpler than trying to change the
current DRM API to accommodate.
In order to facilitate testing of correct handling of this limitation,
we also expose a debugfs interface to manually control the threshold for
when we start trying to flip the notifier context. We will use this in
igt to trigger a context flip for testing purposes without needing to
wait for the notifier to completely fill up. This threshold is reset
to the default value set by nouveau after each capture, and is exposed
in a separate folder within each CRTC's debugfs directory labelled
"nv_crc".
Changes since v1:
* Forgot to finish saving crc.h before saving, whoops. This just adds
some corrections to the empty function declarations that we use if
CONFIG_DEBUG_FS isn't enabled.

* Don't check return code from debugfs_create_dir() or

Originally when trying to fix the issue of runtime PM references with
non-blocking CRTCs on nv50, I ended up stumbling on this code when
trying to remove nouveau_drm->have_disp_power_ref, and attempted to fix
it to remove the dependency on have_disp_power_ref. However, Ilia Mirkin
pointed out that this code is actually completely useless, as pre-nv50
never had runtime PM support in the first place! Go figure.
So, since it's useless just get rid of it. Note that since the only
thing nouveau_crtc_set_config() was doing was grabbing a runtime PM ref,
calling drm_crtc_helper_set_config() then dropping the ref; we can just
remove the function entirely and just call drm_crtc_helper_set_config()
directly.

Atomic helpers really want this instead of the hacked-up legacy
backoff trick, which unfortunately prevents drivers from using their
own private drm_modeset_locks.

nice if they could switch over and just hook up
drm_atomic_helper_legacy_gamma_set() instead.

Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.
Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.
There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.

Add a local 'fb' variable to a few places to get rid of the

So it looks like the code is trying to pick between the passed in fb and
crtc->primary->fb based on that funky 'bool atomic'. But later it will
mix uses of both drm_fb (which was picked by the aforementioned logic)
and crtc->primary->fb. So looks like a bug to me. Let's make it use
drm_fb only.

With atomic nv50+ is already converted over to them, but the old
display code is still using it. Found in a 2 year old patch I have
lying around to un-export these old helpers!
v2: Drop the hand-rolled versions from resume/suspend code. Now that
crtc callbacks do this, we don't need a special case for s/r anymore.
v3: Remove unused variables.
v4: Don't remove drm_crtc_vblank_off from suspend paths, non-atomic
nouveau still needs that. But still switch to drm_crtc_vblank_off
since drm_vblank_off will disappear.

Change return value to int to propagate errors from gamma_set,
and remove start parameter. Updates always use the full size,
and some drivers even ignore the start parameter altogether.
This is needed for atomic drivers, where an atomic commit can
fail with -EINTR or -ENOMEM and should be restarted. This is already
and issue for drm_atomic_helper_legacy_set_gamma, which this patch
fixes up.
Changes since v1:
- Fix compiler warning. (Emil)
- Fix commit message (Daniel)

Nothing too exciting here, there's a larger chunk of work that still
needs more testing but not likely to get that done today - so - here's
the rest of it. Assuming nothing else goes horribly wrong, I should be
able to send the rest Monday if it isn't too late....
Changes:
- Improvements to power sensor support
- Initial attempt at GM108 support
- Minor fixes to GR init + ucode
- Make use of topology information (provided by the GPU) in various
places, should at least fix some fault recovery issues and
engine/runlist mapping confusion on newer GPUs.
