drm/nouveau/fifo/gf100-: recover from host mmu faults
This has been on the TODO list for a while now, recovering from things
such as attempting to execute a push buffer or touch a semaphore in an
unmapped memory area.
The only thing required on the HW side here is that the offending
channel is removed from the runlist, and *not* a full reset of PFIFO.
This used to be a bit messier to handle before the rework to make use
of engine topology info, but is apparently now trivial.

drm/nouveau/kms/nv50: Fix atomic pageflip events.
The new atomic modesetting/pageflip code for nv50+ for
Linux 4.10+ no longer uses pageflip irq's to signal
flip completion. Instead it polls for flip completion
from within a kthread/work queue.
This creates a race between the vblank irq handler
updating the vblank count and timestamp for the
vblank of flip completion, and the kthread's
polling code detecting flip completion and sending
out the flip completion event.
Depending on who executes a few microseconds earlier,
the flip completion event will either contain correct
count/timestamp or a stale count/timestamp from the
previous vblank. This error was observed for about
50% of all executed flips, e.g., observable under DRI2
by the Xorg.log filling with flip handler warning
messages.
Call drm_accurate_vblank_count() before sending
out flip completion events to enforce a vblank
count/ts update for the vblank of flip completion
and avoid stale counts/timestamps.
This fix leads to one redundant call to drm_update_vblank_count
for each completed flip, but no other side effects. On
a ~6 year old Core i7 M620@ 2.67GHz the redundant call
costs about 10 usecs per flip

drm/nouveau: Intercept ACPI_VIDEO_NOTIFY_PROBE
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.

There's two major changes in behavior from before:
- We're now making use of interlocks between core and satellite EVO

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.

As of this commit, we're no longer bothering to point the core surface

channel to the framebuffer passed in a mode_set()/mode_set_base(), and
then use the base channel for any page-flip updates, leaving the core
channel pointing at stale information.
The important thing here is to configure the core surface parameters in
such a way that EVO's error checking is satisfied.
TL;DR: The situation isn't too much different to before.
There may be brief periods of times during modesets where the (garbage)
core surface will be showing. This issue will be resolved once support
for atomic commits has been implemented and we're able to interlock the
updates that involve multiple channels.

drm/nouveau/kms: subclass atomic connector state
This commit implements the atomic property hooks for a connector, and
wraps the legacy interface handling on top of those.
For the moment, a full modeset will be done after any property change
in order to ease subsequent changes. The optimised behaviour will be
restored for Tesla and later (earlier boards always do full modesets)
once atomic commits are implemented.
Some functions are put under the "nouveau_conn" namespace now, rather
than "nouveau_connector", to distinguish functions that will work for
(upcoming) MST connectors too.
