[why]
Driver was passing a wrong command version which to DMCUB which caused
the DMCUB to treat it as 0, so it wouldn't support dual eDP and would
override the panel index to 0 instead of choosing between 0/1.
[how]
Use DMUB_CMD_PSR_CONTROL_VERSION_1 instead of PSR_VERSION_1.

The previous assumption that there will be an optimize_bandwidth call
following every prepare_bandwidth call was incorrect and caused small

The chip ID DEVICE_ID_NV_13FE is not meaningful and represents a legacy

To run correctly, each Virtual Function must be provisioned with
some chunk of shared hardware or firmware resources (like GGTT,
device memory, GuC doorbell IDs, GuC context IDs) and scheduling
parameters (execution quantum or preemption timeout).
All resources assigned to VFs must be excluded from the PF driver
use and may require some additional preparation steps (like setup
of the LMTT or update of the GGTT PTE). Those provisioning details
must be then sent to the GuC firmware as most of those details
will be shared later with the VF drivers during their boot.
Add basic functions to provision VFs with all hardware resources
or scheduling parameters. We will use them shortly in upcoming
patches either in manual provisioning over debugfs, exposed to the
advanced users, or automatic provisioning done by PF driver during
VFs enabling.

The PF driver must maintain additional GT level data per each VF.
This additional per-VF data will be added in upcoming patches and
will include: provisioning configuration (like GGTT space or LMEM
allocation sizes or scheduling parameters), monitoring thresholds
and counters, and more.
As number of supported VFs varies across platforms use flexible
array where first entry will contain metadata for the PF itself
(if such configuration parameter is applicable for the PF) and
all remaining entries will contain data for potential VFs.

VF's drivers can't modify GGTT PTEs except the range explicitly
assigned by the PF driver. To allow hardware enforcement of this
requirement, each GGTT PTE has a field with the VF number that
identifies which VF can modify that particular GGTT PTE entry.
Only PF driver can modify this field and PF driver shall do that
before VF drivers will be loaded. Add function to prepare PTEs.
Since it will be used only by the PF driver, make it available
only for CONFIG_PCI_IOV=y.

Generate the mask of enabled L3 banks for the GT. It is stored with the
rest of the GT topology in a consistent representation across platforms.
For now the L3 bank mask is just printed in the log for developers to
easily figure out the fusing characteristics of machines that they are
trying to debug issues on. Later it can be used to replace existing code
in the driver that requires the L3 bank count (not mask). Also the mask
can easily be exposed to user space in a new query if needed.

I didn't pay close enough attention the last time I tried to fix this
problem - while we currently do correctly take care to make sure we don't
probe a connected eDP port more then once, we don't do the same thing for
eDP ports we found to be disconnected.
So, fix this and make sure we only ever probe eDP ports once and then leave
them at that connector state forever (since without HPD, it's not going to
change on its own anyway). This should get rid of the last few GSP errors
getting spit out during runtime suspend and resume on some machines, as we
tried to reprobe eDP ports in response to ACPI hotplug probe events.

GSP has its own state for keeping track of whether or not a given display
connector is plugged in or not, and enforces this state on the driver. In
particular, AUX transactions on a DisplayPort connector which GSP says is
disconnected can never succeed - and can in some cases even cause
unexpected timeouts, which can trickle up to cause other problems. A good
example of this is runtime power management: where we can actually get
stuck trying to resume the GPU if a userspace application like fwupd tries
accessing a drm_aux_dev for a disconnected port. This was an issue I hit a
few times with my Slimbook Executive 16 - where trying to offload something
to the discrete GPU would wake it up, and then potentially cause it to
timeout as fwupd tried to immediately access the dp_aux_dev nodes for
nouveau.
Likewise: we don't really have any cases I know of where we'd want to
ignore this state and try an aux transaction anyway - and failing pointless
aux transactions immediately can even speed things up. So - let's start
enabling/disabling the aux bus in nouveau_dp_detect() to fix this. We
enable the aux bus during connector probing, and leave it enabled if we
discover something is actually on the connector. Otherwise, we just shut it
off.
This should fix some people's runtime PM issues (like myself), and also get
rid of quite of a lot of GSP error spam in dmesg.

The commit 509433d8146c ("drm/v3d: Expose the total GPU usage stats on sysfs")
introduced the calculation of global GPU stats. For the regards, it used
the already existing infrastructure provided by commit 09a93cc4f7d1 ("drm/v3d:
Implement show_fdinfo() callback for GPU usage stats"). While adding
global GPU stats calculation ability, the author forgot to delete the
existing one.
Currently, the value of `enabled_ns` is incremented twice by the end of
the job, when it should be added just once. Therefore, delete the
leftovers from commit 509433d8146c ("drm/v3d: Expose the total GPU usage
stats on sysfs").

crc checksums are used to validate the output. Normally they're part
of the actual display hardware but on virtual stack there's nothing
to automatically generate them.
Implement crc generation for the vmwgfx stack. This works only on
screen targets, where it's possibly to easily make sure that the
guest side contents of the surface matches the host sides output.
Just like the vblank support, crc generation can only be enabled via:
guestinfo.vmwgfx.vkms_enable = "TRUE"
option in the vmx file.
Makes IGT's kms_pipe_crc_basic pass and allows a huge number of other
IGT tests which require CRC generation of the output to actually run
on vmwgfx. Makes it possible to actually validate a lof of the kms and
drm functionality with vmwgfx.

By default vmwgfx doesn't support vblanking or crc generation which
makes it impossible to use various IGT tests to validate vmwgfx.
Implement virtual kernel mode setting, which is mainly related to
simulated vblank support.
Code is very similar to amd's vkms and the vkms module itself, except
that it's integrated with vmwgfx three different output technologies -
legacy, screen object and screen targets.
Make IGT's kms_vblank pass on vmwgfx and allows a lot of other IGT
tests to run with vmwgfx.
Support for vkms needs to be manually enabled by adding:
guestinfo.vmwgfx.vkms_enable = "TRUE"
somewhere in the vmx file, otherwise it's off by default.

The table of primary plane formats wasn't sorted at all, leading to
applications picking our least desirable formats by defaults.
Sort the primary plane formats according to our order of preference.
Nice side-effect of this change is that it makes IGT's kms_atomic
plane-invalid-params pass because the test picks the first format
which for vmwgfx was DRM_FORMAT_XRGB1555 and uses fb's with odd sizes
which make Pixman, which IGT depends on assert due to the fact that our
16bpp formats aren't 32 bit aligned like Pixman requires all formats
to be.

The conditional was supposed to prevent enabling of a crtc state
without a set primary plane. Accidently it also prevented disabling
crtc state with a set primary plane. Neither is correct.
Fix the conditional and just driver-warn when a crtc state has been
enabled without a primary plane which will help debug broken userspace.
Fixes IGT's kms_atomic_interruptible and kms_atomic_transition tests.

vmwgfx never supported prime import of external buffers. Furthermore the
driver exposes two different objects to userspace: vmw_surface's and
gem buffers but prime import/export only worked with vmw_surfaces.
Because gem buffers are used through the dumb_buffer interface this meant
that the driver created buffers couldn't have been prime exported or
imported.
Fix prime import/export. Makes IGT's kms_prime pass.

We only pool write combined and uncached allocations because they
require extra overhead on allocation and release.
If we also pool cached NUMA it not only means some extra unnecessary
overhead, but also that under memory pressure it can happen that
pages from the wrong NUMA node enters the pool and are re-used
over and over again.
This can lead to performance reduction after running into memory
pressure.
v2: restructure and cleanup the code a bit from the internal hack to
test this.
