This check is useful for drivers that do not have DRIVER_ATOMIC set but
have atomic modesetting internally implemented. Wrap the check into a
function since this is used in many places and as a bonus, the function
name helps to document what the check is for.
v2:
Change return type to bool (Ville)
Move the function drm_atomic.h (Daniel)
Fixed comment marker for documentation

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.

We need to call drm_helper_hpd_irq_event() on resume to properly detect
monitor connection / disconnection on some laptops. For runtime-resume
(which gets called on resume from normal suspend too) we must call
drm_helper_hpd_irq_event() from a workqueue to avoid a deadlock.
Rename acpi_work to hpd_work, and move it out of the #ifdef CONFIG_ACPI
blocks to make it suitable for generic work.

Various notebooks with nvidia GPUs generate an ACPI_VIDEO_NOTIFY_PROBE
acpi-video event when an external device gets plugged in (and again on
modesets on that connector), the default behavior in the acpi-video
driver for this is to send a KEY_SWITCHVIDEOMODE evdev event, which
causes e.g. gnome-settings-daemon to ask us to rescan the connectors
(good), but also causes g-s-d to switch to mirror mode on a newly plugged
monitor rather then using the monitor to extend the desktop (bad)
as KEY_SWITCHVIDEOMODE is supposed to switch between extend the desktop
vs mirror mode.
More troublesome are the repeated ACPI_VIDEO_NOTIFY_PROBE events on
changing the mode on the connector, which cause g-s-d to switch
between mirror/extend mode, which causes a new ACPI_VIDEO_NOTIFY_PROBE
event and we end up with an endless loop.
This commit fixes this by adding an acpi notifier block handler to
nouveau_display.c to intercept ACPI_VIDEO_NOTIFY_PROBE and:
1) Wake-up runtime suspended GPUs and call drm_helper_hpd_irq_event()
on them, this is necessary in some cases for the GPU to detect connector
hotplug events while runtime suspended
2) Return NOTIFY_BAD to stop acpi-video from emitting a bogus
KEY_SWITCHVIDEOMODE key-press event
There already is another acpi notifier block handler registered in
drivers/gpu/drm/nouveau/nvkm/engine/device/acpi.c, but that is not
suitable since that one gets unregistered on runtime suspend, and
we also want to intercept ACPI_VIDEO_NOTIFY_PROBE when runtime suspended.

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.

This commit implements the atomic commit interfaces, and implements the
legacy modeset and page flipping interfaces on top of them.
There's two major changes in behavior from before:
- We're now making use of interlocks between core and satellite EVO
channels, which greatly improves our ability to keep their states
synchronised.
- DPMS is now implemented as a full modeset to either tear down the
entire pipe (or bring it back up). This choice was made mostly
to ease the initial implementation, but I'm also not sure what we
gain by bring backing the old behaviour. We shall see.
This does NOT currently expose the atomic ioctl by default, due to
limited testing having been performed.

This is different from the equivilant functions in the atomic helpers in
that we fully disable the pipe instead of just setting it to inactive.
We do this (primarily) to ensure the framebuffer cleanup paths are hit,
allowing buffers to be un-pinned from memory so they can be evicted to
system memory and not lose their contents while suspended.

nouveau leaks a runtime pm ref if at least one CRTC is enabled on
unload. The ref is taken by nouveau_crtc_set_config() and held as long
as a CRTC is in use.
nv04_display_destroy() should solve this by turning off all CRTCs, but
(1) nv50_display_destroy() doesn't do the same and
(2) it's broken since commit d6bf2f370703 ("drm/nouveau: run mode_config
destructor before destroying internal display state") because the
crtc structs are torn down by drm_mode_config_cleanup() before being
turned off. Also, there's no locking.
Move the code to turn off all CRTCs from nv04_display_destroy() to
nouveau_display_destroy() so that it's called for both nv04 and nv50
and before drm_mode_config_cleanup(). Use drm_crtc_force_disable_all()
helper to save on code and have proper locking.

In the display resume path, move the calls to drm_vblank_on()
after the point when the display engine is running again.
Since changes were made to drm_update_vblank_count() in Linux 4.4+
to emulate hw vblank counters via vblank timestamping, the function
drm_vblank_on() now needs working high precision vblank timestamping
and therefore working scanout position queries at time of call.
These don't work before the display engine gets restarted, causing
miscalculation of vblank counter increments and thereby large forward
jumps in vblank count at display resume. These jumps can cause client
hangs on resume, or desktop hangs in the case of composited desktops.
Fix this Linux 4.4 regression by reordering calls accordingly.

drm/irq: Make pipe unsigned and name consistent
Triggering a warning when trying to sample the vblank timestamp for a
non-existing pipe. There's a few ways to fix this:
- Open-code the old behaviour, which just enshrines this slight
breakage of the userspace ABI.
- Revert Mario's commit and again inflict broken timestamps, again not
pretty.
- Fix this for real by delaying the pageflip TS until the next vblank
interrupt, thereby making it accurate.
This patch implements the third option. Since having a page flip
interrupt that happens when the pageflip gets armed and not when it
completes in the next vblank seems to be fairly common (older i915 hw
works very similarly) create a new helper to arm vblank events for
such drivers.
v2 (Mario Kleiner):
- Fix function prototypes in drmP.h
- Add missing vblank_put() for pageflip completion without
pageflip event.
- Initialize sequence number for queued pageflip event to avoid
trouble in drm_handle_vblank_events().
- Remove dead code and spelling fix.
v3 (Mario Kleiner):
- Add a signed-off-by and cc stable tag per Ilja's advice.
v4 (Thierry Reding):
- Fix kerneldoc typo, discovered by Michel Dänzer
- Rearrange tags and changelog

This continues the pattern started in commit cc1ef118fc09 ("drm/irq:
Make pipe unsigned and name consistent"). This is applied to the public
APIs and driver callbacks, so pretty much all drivers need to be updated
to match the new prototypes.

linedur_ns, and especially pixeldur_ns are becoming rather inaccurate
to be used for the vblank timestamp correction. With 4k@60 the pixel
duration is already below 2ns, so the amount of error due to the
truncation to nanoseconds is introducing quite a bit of error.
We can avoid such problems if we instead calculate the timestamp
delta_ns directly from the dislay timings, avoiding the use of
these intermediate truncated values.

Collect the timestamping constants alongside the rest of the relevant
stuff under drm_vblank_crtc.
We can now get rid of the 'refcrtc' parameter to
drm_calc_vbltimestamp_from_scanoutpos().

A variety of tweaks to the NVIF library interfaces, mostly ripping out
things that turned out to be not so useful.
- Removed refcounting from nvif_object, callers are expected to not be
stupid instead.
- nvif_client is directly reachable from anything derived from nvif_object,
removing the need for heuristics to locate it
- _new() versions of interfaces, that allocate memory for the object
they construct, have been removed. The vast majority of callers used
the embedded _init() interfaces.
- No longer storing constructor arguments (and the data returned from
nvkm) inside nvif_object, it's more or less unused and just wastes
memory.

Having a RAM device does not make sense for chips like GK20A which have
no dedicated video memory. The dummy RAM device that we used so far
works as a temporary band-aid, but in the longer term it is desirable
for the driver to be able to work without any kind of VRAM.
This patch adds a few conditionals in places where a RAM device was
assumed to be present and allows some more objects to be allocated from
the TT domain, allowing Nouveau to handle GPUs for which
pfb->ram == NULL.

NVKM is having it's namespace switched to nvkm_, which will conflict
with these functions (which are workarounds for the fact that as of
yet, we still aren't able to split DRM and NVKM completely).
A comparison of objdump disassemblies proves no code changes.

This reverts commit 355a70183848f21198e9f6296bd646df3478a26d.
This had some bad side effects under normal operation, and should
have been dropped earlier.

Preparation for transition to planes, which use framebuffers for the
cursor image. We've always done copies from the userspace buffer up
until now for legacy reasons, there's no good reason to do so on the
chipsets this code covers.

We have the ability to move buffers around in the kernel if necessary,
and should probably use it rather than failing if userspace passes us
a non-contig buffer for a plane.
The NOUVEAU_GEM_TILE_NONCONTIG flag from userspace will become a mere
initial placement hint once all the relevant paths have been updated.
