I suspect the version bump is just to signify that the table now specifies
pad macro/links instead of SOR/sublinks.
For our usage of the table, just recognising the new version is enough.

We need to call drm_helper_hpd_irq_event() on resume to properly detect
monitor connection / disconnection on some laptops, use hpd_work for
this to avoid deadlocks.

We need to call drm_helper_hpd_irq_event() on resume to properly detect

(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.

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
Successfully tested on GeForce 9500/9600/330M so far.

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.

This sequence is incorrect for GP102/GP104 boards. This is now being

From visual inspection of traces, what we currently implement appears to

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 avoids an issue that occurs when we're attempting to preempt multiple
channels simultaneously. HW seems to ignore preempt requests while it's
still processing a previous one, which, well, makes sense.
Fixes random "fifo: SCHED_ERROR 0d []" + GPCCS page faults during parallel
piglit runs on (at least) GM107.

Look for firmware files using the legacy ("nouveau/nvxx_fucxxxx") path
if they cannot be found in the new, "official" path. User setups were
broken by the switch, which is bad.
There are only 4 firmware files we may want to look up that way, so
hardcode them into the lookup function. All new firmware files should
use the standard "nvidia/<chip>/gr/" path.

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.
