Add an extra remapping step between the logical state of the LUTs
(hw.(de)gamma_lut) as specified via uapi/bigjoiner copy vs.
the actual state of the LUTs programmed into the hardware.
With this we should be finally able finish the (de)gamma
readout/state checker support for the remaining platforms
(ilk-skl) where the same hardware LUT can be positioned
either before or after the pipe CSC unit. Where we position
it depends on factors such as presence of the logical degamma
LUT, RGB vs. YCbCr output, full vs. limited RGB quantization
range.
Without the extra remapping step the state readout doesn't
really know whether the LUT read from the hardware is the
degamma or gamma LUT, and so we is unable to accurately store
it into our crtc state. With the remapping step we know
exactly where to put it given the order of the LUT vs. CSC
in the hardware state.
Only the initial hw->uapi state readout done during driver
load/resume still has the problem of not really knowing
what to do with the LUT(s). But we can just assume 1:1
mapping there and let subsequent commits fix things up.
Another benefit is that we now have a place for purely
internal LUTs, without complicating the bigjoiner uapi->hw
copy logic. This should prove useful for streamlining
glk degamma LUT handling.

Make ilk_load_luts() ready for a degamma lut. Currently we never
have one, but soon we may get one from readout, and I think we
may want to change the state computation such that we may end up
with one even when userspace has simply supplied a gamma lut.
At least the code now follows the path laid out by the ivb/bdw
counterpars.

It's important to get the initial size of cotables right because
otherwise every app needs to start with a synchronous cotable resize.
This has an measurable impact on system wide performance but is not
relevant for long running single full screen apps for which the cotable
resizes will happen early in the lifecycle and will continue running
just fine.
To eliminate the initial cotable resizes match the initial sizes to what
the userspace expects. The actual result of the patch is simply setting
the initial size of two of the cotables to a size that will align them
to two pages instead of one.
For a piglit run, before:
name | total | per frame | per sec
vmw_cotable_resize | 1405 | 0.12 | 1.58
vmw_execbuf_ioctl | 290805 | 25.43 | 326.05

The explicit vblank handling was never finished. The driver never had
the full implementation of vblank and what was there is emulated
by DRM when the driver doesn't pretend to be implementing it itself.
Let DRM handle the vblank emulation and stop pretending the driver is
doing anything special with vblank. In the future it would make sense
to implement helpers for full vblank handling because vkms and
amdgpu_vkms already have that code. Exporting it to common helpers and
having all three drivers share it would make sense (that would be largely
just to allow more of igt to run).

Instead of using vmwgfx specific framebuffer implementation use the drm
fb helpers. There's no change in functionality, the only difference
is a reduction in the amount of code inside the vmwgfx module.
drm fb helpers do not deal correctly with changes in crtc preferred mode
at runtime, but the old fb code wasn't dealing with it either.
Same situation applies to high-res fb consoles - the old code was
limited to 1176x885 because it was checking for legacy/deprecated
memory limites, the drm fb helpers are limited to the initial resolution
set on fb due to first problem (drm fb helpers being unable to handle
hotplug crtc preferred mode changes).
This also removes the kernel config for disabling fb support which hasn't
been used or supported in a very long time.

This is part of an effort to move from the vmwgfx_open_hash hashtable to
linux/hashtable implementation.
Refactor the ref_hash hashtable, used for fast lookup of reference objects
associated with a ttm file.
This also exposed a problem related to inconsistently using 32-bit and
64-bit keys with this hashtable. The hash function used changes depending
on the size of the type, and results are not consistent across numbers,
for example, hash_32(329) = 329, but hash_long(329) = 328. This would
cause the lookup to fail for objects already in the hashtable, since keys
of different sizes were being passed during adding and lookup. This was
not an issue before because vmwgfx_open_hash always used hash_long.
Fix this by always using 64-bit keys for this hashtable, which means that
hash_long is always used.

The currently default Round-Robin GPU scheduling can result in starvation
of entities which have a large number of jobs, over entities which have
a very small number of jobs (single digit).
This can be illustrated in the following diagram, where jobs are
alphabetized to show their chronological order of arrival, where job A is
the oldest, B is the second oldest, and so on, to J, the most recent job to
arrive.
---> entities
j | H-F-----A--E--I--
o | --G-----B-----J--
b | --------C--------
s\/ --------D--------
WLOG, assuming all jobs are "ready", then a R-R scheduling will execute them
in the following order (a slice off of the top of the entities' list),
H, F, A, E, I, G, B, J, C, D.
However, to mitigate job starvation, we'd rather execute C and D before E,
and so on, given, of course, that they're all ready to be executed.
So, if all jobs are ready at this instant, the order of execution for this
and the next 9 instances of picking the next job to execute, should really
be,
A, B, C, D, E, F, G, H, I, J,
which is their chronological order. The only reason for this order to be
broken, is if an older job is not yet ready, but a younger job is ready, at
an instant of picking a new job to execute. For instance if job C wasn't
ready at time 2, but job D was ready, then we'd pick job D, like this:
0 +1 +2 ...
A, B, D, ...
And from then on, C would be preferred before all other jobs, if it is ready
at the time when a new job for execution is picked. So, if C became ready
two steps later, the execution order would look like this:
......0 +1 +2 ...
A, B, D, E, C, F, G, H, I, J
This is what the FIFO GPU scheduling algorithm achieves. It uses a
Red-Black tree to keep jobs sorted in chronological order, where picking
the oldest job is O(1) (we use the "cached" structure), and balancing the
tree is O(log n). IOW, it picks the *oldest ready* job to execute now.
The implementation is already in the kernel, and this commit only changes
the default GPU scheduling algorithm to use.
This was tested and achieves about 1% faster performance over the Round
Robin algorithm.

A typical DP-MST unplug removes a KMS connector. However care must
be taken to properly synchronize with user-space. The expected
sequence of events is the following:
1. The kernel notices that the DP-MST port is gone.
2. The kernel marks the connector as disconnected, then sends a
uevent to make user-space re-scan the connector list.
3. User-space notices the connector goes from connected to disconnected,
disables it.
4. Kernel handles the IOCTL disabling the connector. On success,
the very last reference to the struct drm_connector is dropped and
drm_connector_cleanup() is called.
5. The connector is removed from the list, and a uevent is sent to tell
user-space that the connector disappeared.
The very last step was missing. As a result, user-space thought the
connector still existed and could try to disable it again. Since the
kernel no longer knows about the connector, that would end up with
EINVAL and confused user-space.
Fix this by sending a hotplug uevent from drm_connector_cleanup().

This reverts commit 981f09295687f856d5345e19c7084aca481c1395.
It turns out this causes logically active but disconnected DP MST
connectors to disappear from the KMS resources list, and Mutter
then assumes the connector is already disabled. Later on Mutter tries
to re-use the same CRTC but fails since on the kernel side it's still
tied to the disconnected DP MST connector.

If GuC is being used and we initialized GuC-error-capture,
we need to be warning if we don't provide an error-capture
register list in the firmware ADS, for valid GT engines.
A warning makes sense as this would impact debugability
without realizing why a reglist wasn't retrieved and reported
by GuC.
However, depending on the platform, we might have certain
engines that have a register list for engine instance error state
but not for engine class. Thus, add a check only to warn if the
register list was non existent vs an empty list (use the
empty lists to skip the warning).
NOTE: if a future platform were to introduce new registers
in place of what was an empty list on existing / legacy hardware
engines no warning is provided as the empty list is meant
to be used intentionally. As an example, if a future hardware
were to add blitter engine-class-registers (new) on top
of the legacy blitter engine-instance-register (HEAD, TAIL, etc.),
no warning is generated.

A workaround was added to the driver to allow compute workloads to run
'forever' by disabling pre-emption on the RCS engine for Gen12.
It is not totally unbound as the heartbeat will kick in eventually
and cause a reset of the hung engine.
However, this does not work well in GuC submission mode. In GuC mode,
the pre-emption timeout is how GuC detects hung contexts and triggers
a per engine reset. Thus, disabling the timeout means also losing all
per engine reset ability. A full GT reset will still occur when the
heartbeat finally expires, but that is a much more destructive and
undesirable mechanism.
The purpose of the workaround is actually to give compute tasks longer
to reach a pre-emption point after a pre-emption request has been
issued. This is necessary because Gen12 does not support mid-thread
pre-emption and compute tasks can have long running threads.
So, rather than disabling the timeout completely, just set it to a
'long' value.
v2: Review feedback from Tvrtko - must hard code the 'long' value
instead of determining it algorithmically. So make it an extra CONFIG
definition. Also, remove the execlist centric comment from the
existing pre-emption timeout CONFIG option given that it applies to
more than just execlists.

Compute workloads are inherently not pre-emptible for long periods on
current hardware. As a workaround for this, the pre-emption timeout
for compute capable engines was disabled. This is undesirable with GuC
submission as it prevents per engine reset of hung contexts. Hence the
next patch will re-enable the timeout but bumped up by an order of
magnitude.
However, the heartbeat might not respect that. Depending upon current
activity, a pre-emption to the heartbeat pulse might not even be
attempted until the last heartbeat period. Which means that only one
period is granted for the pre-emption to occur. With the aforesaid
bump, the pre-emption timeout could be significantly larger than this
heartbeat period.
So adjust the heartbeat code to take the pre-emption timeout into
account. When it reaches the final (high priority) period, it now
ensures the delay before hitting reset is bigger than the pre-emption
timeout.
v2: Fix for selftests which adjust the heartbeat period manually.
v3: Add FIXME comment about selftests. Add extra FIXME comment and
drm_notices when setting heartbeat to a non-default value (review
feedback from Tvrtko)

VPG doesn't have the ability to mute audio output by sending all 0s in
audio SDP. The existing implemention is disabling audio SDP instead.
This is same as what dp_audio_enable does. Since it is no longer
referenced by any callers, we decided to remove this interface for
simplicity.

[why]
1. As recommended by hardware team, don't enable APG when stream is not
enabled.
2. Move audio stream encoder programming into link_hwss.
[how]
1. Merge dp_audio_enable into enable audio stream hw sequence.
2. Move stream encoder programming into link hwss level to unify stream
encoder programming interface.

As part of the programming expectation for using DML functions, DC
requires that any DML function invoked outside DML uses:
DC_FP_START();
... dml function ...
DC_FP_END();
Additionally, all the DML functions that can be invoked outside the DML
folder call the function dc_assert_fp_enabled(), which is responsible
for triggering a warning in the case that the DML function was not
guarded by the DC_FP_START/END. For this reason, call DC_FP_START/END
inside DML is wrong, and this commit removes all of those references.

In the S2idle suspend/resume phase the gfxoff is keeping functional so
some IP blocks will be likely to reinitialize at gfxoff entry and that
will result in failing to program GC registers.Therefore, let disallow
gfxoff until AMDGPU IPs reinitialized completely.

IMU is a new firmware for GFX11.
There are four means by which firmware version can be queried
from the driver: device attributes, vf2pf, debugfs,
and the AMDGPU_INFO_FW_VERSION option in the amdgpu info ioctl.
Add IMU as an option for those four methods.
V2: Added debugfs
