drm/amd/display: Handle branch device with DFP count = 0 case.

[Why]
When you have a SST branch device the driver, Even no sink device connected,
it also send HPD with a valid EDID. Driver will config it to DP sink.
Therefore, there're two displays in display setting.

DPCD 0x05, DFP_PRESENT = 1 (branch device),
DFP_TYPE = 00 (Display Port)

[How]
Driver determine DPCD 0x05 DFP_PRESENT = 1(branch) as an active dongle
And check DFP count.

drm/amd/display: add preferred pipe split logic

[why]
existing logic finds "first free pipe from 5 -> 0" to split
this will cause certain sequences to require DC to move
an MPCC from one tree to another, which is unsupported
this leads to blackscreen

to mitigate this problem, we will always try to acquire the
"preferred" pipe, and each pipe has a unique preferred pipe
this means we avoid most of the scenarios where

Y41x formats is a 4:4:4 format, so it can be addressed with pixel level accuracy.
Meanwhile it seems that while rotating YUYV 4:2:2 formats need a multiple of 2

For YUV 4:2:2, the spec says that w/h should always be even, but we get
away with odd height while unrotated. When rotating it seems corruption
occurs with an odd x/y, and w/h should always be even.

drm/i915: Update TRANS_MSA_MISC for fastsets

Update the DP MSA MISC bits for fastsets. This is needed
when we change between limited and full range RGB output.

On HSW+ changing limited_range does not currently result in a
full modeset since we have don't have the readout code for it
(for DP we could, and probably should, readout from TRANS_MSA_MISC
itself, for HDMI we would have to rely on the infoframe). So
the PIPE_CONF_CHECK() is only performed for pre-HSW platforms.
That means any change in the value will result in a fastset
instead. Fortunately there is no prohibition to changing
TRANS_MSA_MISC dynamically, so it looks like we can legally do
fastsets for this.

drm/fb-helper: set fbi->fix.id in fill_info()

Looking at the oldest/most popular drivers ${driver}drmfb seems to be
the standard, except i915.ko went with "inteldrmfb". I guess renaming
that for consistency won't hurt, it definitely confused me when I
started with kms 10 years ago.

I hope this never became uapi ... worst case drivers can overwrite it
after having called fill_info().

Since subsequent patches change this for some drivers later on in the
series, here's the exhaustive list of where all fix.id is used:
- /proc/fb which prints the minor number and fix.id name.
- per-fb sysfs name file
- getfix ioctl, which is used by fbset only to print out the name when
dumping information
- lots and lots of places in dmesg, anytime anything happens with an
fbdev really

I think minimal to 0 chances that changing this will screw up a config
script or something, since outside of informational message it's not
used by anything to identify which fbdev maps to which minor. After
all the last fbset release is from 1999, and that predates even devfs
I think.

v2: Rebase and amend commit message, thanks to Ilia for pointing out
that this needs to be spelled out.

drm/fb-helper: Add fill_info() functions

The fbdev split between fix and var information is kinda
pointless for drm drivers since everything is fixed: The fbdev
emulation doesn't support changing modes at all.

Create a new simplified helper and use it in the generic fbdev
helper code. Follow-up patches will beef it up more and roll
it out to all drivers.

v2: We need to keep sizes, since they might not match the fb dimensions

Add the io-64-nonatomic-lo-hi include to have readq and writeq available

drm/i915: add HAS_FORCEWAKE flag to uncore

We have several cases where we don't have forcewake (older gens, GVT and
planned display-only uncore), so, instead of checking every time against
the various condition, save the info in a flag and use that.

Note that this patch also change the behavior for gen5 with vpgu
enabled, but this is not an issue since we don't support vgpu on gen5.

v2: split out from previous path, fix check for missing case (Paulo)
v3: Inline helper for clarity in testing flags

drm/fbdev: Make skip_vt_switch the default

KMS drivers really should all be able to restore their display state
on resume without fbcon helping out. So make this the default.

Since I'm not entirely foolish, make it only a default, which drivers
can still override. That way when the inevitable regression report
happens I can fix things up with a one-liner plus FIXME comment that
someone should fix up the suspend/resume code in that driver.

But at least all new drivers won't be broken by accident as soon as
you turn off fbcon because "suspend/resume worked when I tested it".

drm/i915: Disable C3 when enabling vblank interrupts on i945gm

The AGPBUSY thing doesn't work on i945gm anymore. This means
the gmch is incapable of waking the CPU from C3 when an interrupt
is generated. The interrupts just get postponed indefinitely until
something wakes up the CPU. This is rather annoying for vblank
interrupts as we are unable to maintain a steady framerate
unless the machine is sufficiently loaded to stay out of C3.

To combat this let's use pm_qos to prevent C3 whenever vblank
interrupts are enabled. To maintain reasonable amount of powersaving
we will attempt to limit this to C3 only while leaving C1 and C2
enabled.

Pull perf updates from Thomas Gleixner:
 "A larger set of perf updates.

  Not all of them are strictly fixes, but that's solely the tip
  maintainers fault as they let the timely -rc1 pull request fall
  through the cracks for various reasons including travel. So I'm
  sending this nevertheless because rebasing and distangling fixes and
  updates would be a mess and risky as well. As of tomorrow, a strict
  fixes separation is happening again. Sorry for the slip-up.

  Kernel:

   - Handle RECORD_MMAP vs. RECORD_MMAP2 correctly so different
     consumers of the mmap event get what they requested.

  Tools:

   - A larger set of updates to perf record/report/scripts vs. time
     stamp handling

   - More Python3 fixups

   - A pile of memory leak plumbing

   - perf BPF improvements and fixes

   - Finalize the perf.data directory storage"

[ Note: the kernel part is strictly a fix, the updates are purely to
  tooling       - Linus ]
