9b27390139 drm/i915: Use the correct crtc when sanitizing plane mapping
When we decide that a plane is attached to the wrong pipe we try
to turn off said plane. However we are passing around the crtc we
think that the plane is supposed to be using rather than the crtc
it is currently using. That doesn't work all that well because
we may have to do vblank waits etc. and the other pipe might
not even be enabled here. So let's pass the plane's current crtc to
intel_plane_disable_noatomic() so that it can its job correctly.

To do that semi-cleanly we also have to change the plane readout
to record the plane's visibility into the bitmasks of the crtc
where the plane is currently enabled rather than to the crtc
we want to use for the plane.

One caveat here is that our active_planes bitmask will get confused
if both planes are enabled on the same pipe. Fortunately we can use
plane_mask to reconstruct active_planes sufficiently since
plane_mask still has the same meaning (is the plane visible?)
during readout. We also have to do the same during the initial
plane readout as the second plane could clear the active_planes
bit the first plane had already set.

v2: Rely on fixup_active_planes() to populate active_planes fully (Daniel)
    Add Daniel's proposed comment to better document why we do this
    Drop the redundant intel_set_plane_visible() call

7cada4d0b7 drm/i915: Restore vblank interrupts earlier
Plane sanitation needs vblank interrupts (on account of CxSR disable).
So let's restore vblank interrupts earlier.

3f6d5ba173 drm/i915: Check fb stride against plane max stride
commit 4e0b83a567 ("drm/i915: Extract per-platform plane->check()
functions") removed the plane max stride check for sprite planes.
I was going to add it back when introducing GTT remapping for the
display, but after further thought it seems better to re-introduce
it separately.

So let's add the max stride check back. And let's do it in a nicer
form than what we had before and do it for all plane types (easy
now that we have the ->max_stride() plane vfunc).

Only sprite planes really need this for now since primary planes
are capable of scanning out the current max fb size we allow, and
cursors have more stringent stride checks elsewhere.

cfea88a4d8 drm/nouveau: Start using new drm_dev initialization helpers
Per the documentation in drm_get_pci_dev(), this function is deprecated
and shouldn't be used anymore. As it turns out, we're going to need to
stop using drm_get_pci_dev() anyway in order to allow us to turn off the
card before full system shutdowns, otherwise we'll hit race conditions
with userspace while trying to tear down the card on shutdown.

So, start using drm_dev_get() and drm_dev_put(), and just turn our
load/unload callbacks into open coded init/fini() functions.

e15e4c13e5 drm/nouveau: Refactor nvXX_backlight_init()
There's literally no difference between any of the backlight init
functions besides the backlight properties they set and the backlight
callbacks that they set, so move all of the duplicated backlight init
code out of there and into nouveau_backlight_init().

This gets rid of a lot of copy pasta!

Changes since v1:
- Some of the pre-refactor callbacks were storing nv_encoder in callback
  data for the backlight devices that they registered, as opposed to
  nouveau_drm. This got missed and caused some bugs that didn't
  originally appear on my setup (NULL kernel derefs) for some reason.
  So, fix this by finding the nouveau_encoder in
  nouveau_backlight_init(), and using that as the callback data for all
  gens instead even if they don't care about the encoder.

While I haven't actually gone into the details of what's causing this to
happen (maybe the kernel removes the backlight device in the device core
before we get to it?), it doesn't really matter anyway because the way
nouveau handles backlights has long since been deprecated.

According to the documentation on the drm_connector->late_register()
hook, the ->late_register() hook should be used for adding extra
connector-related devices. Vice versa, the ->early_unregister() hook is
meant to be used for removing those devices.

So: gut nouveau_drm->bl_list and nouveau_drm->backlight, and replace
them with per-connector backlight structures. Additionally, move
backlight registration/teardown into the ->late_register() and
->early_unregister() hooks so that DRM can give us a chance to remove
the backlight before the connector is even removed. This appears to fix
the problem once and for all.

Changes since v2:
- Use NV_INFO_ONCE for printing GMUX information, since otherwise this
  will end up printing that message for as many times as we have
  connectors

582f58de36 drm/amdgpu: Suppress keypresses from ACPI_VIDEO events
Currently we return NOTIFY_DONE for any event which we don't think is
ours. However, many laptops will send more then just an ATIF event and
will also send an ACPI_VIDEO_NOTIFY_PROBE event as well. Since we don't
check for this, we return NOTIFY_DONE which causes a keypress for the
ACPI event to be propogated to userspace. This is the equivalent of
someone pressing the display key on a laptop every time there's a
hotplug event.

So, check for ACPI_VIDEO_NOTIFY_PROBE events and suppress keypresses
from them.

f2d9bbc996 drm/amdgpu: Limit the max mc address to hole start
For the vram_start is 0 case, the gart range will be from 0x0000FFFF00000000
to 0x0000FFFF1FFFFFFF, which will cause the engine hang.

So to avoid the hole, limit the max mc address to AMDGPU_GMC_HOLE_START.:wq
