drm: move allocation out of drm_get_format_name()
to be able to apply his patches without conflicts.
Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
It has been suggested that having per-plane modifiers is making life
more difficult for userspace, so let's just retire modifier[1-3] and
use modifier[0] to apply to the entire framebuffer.
Obviosuly this means that if individual planes need different tiling
layouts and whatnot we will need a new modifier for each combination
of planes with different tiling layouts.
For a bit of extra backwards compatilbilty the kernel will allow
non-zero modifier[1+] but it require that they will match modifier[0].
This in case there's existing userspace out there that sets
modifier[1+] to something non-zero with planar formats.
Mostly a cocci job, with a bit of manual stuff mixed in.

The graphics driver is supposed to define the DIDL, which are used for
_DOD, not the BIOS. Restore that behaviour.
This is basically a revert of
commit 3143751ff5
Author: Zhang Rui <rui.zhang@intel.com>
Date: Mon Mar 29 15:12:16 2010 +0800
drm/i915: set DIDL using the ACPI video output device _ADR method return.
which went out of its way to cater to a specific BIOS, setting up DIDL
based on _ADR method. Perhaps that approach worked on that specific
machine, but on the machines I checked the _ADR method invents the
device identifiers out of thin air if DIDL has not been set. The source
for _ADR is also supposed to be the DIDL set by the driver, not the
other way around.
With this, we'll also limit the number of outputs to what the driver
actually has.
A side effect of this change is that the DIDL, and by proxy CADL, will
be initialized in the order of the connector list. That, in turn, has
internal panels in front, ensuring they're included in the DIDL and CADL
lists. Hopefully this ensures the BIOS does not block backlight hotkey
events, thinking the internal panel is off.

For a single_port_submission context, GVT expects that it can only be
submitted to port 0, and there shouldn't be any other context in port 1
at the same time. This is required by GVT-g context to have an opportunity
to save/restore some non-hw context render registers.
This patch is to workaround GVT-g.

Looking at the ioctl permission checks I noticed that it's impossible
to import gem buffers into a control nodes, and fd2handle/handle2fd
also don't work, so no joy with dma-bufs.
The only way to do anything with a control node is by drawing stuff
into a dumb buffer and displaying that. I suspect control nodes are an
entirely unused thing, and a cursory check shows that there does not
seem to be any callers of drmOpenControl nor of the other drmOpen
functions using DRM_MODE_CONTROL.
Since I don't like dead uabi, let's remove it. But since this would be
a really big change I think it's better to start out small by simply
not registering anything. We can garbage-collect the dead code later
on, once we're sure it's really not used anywhere.

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.
