The only real platform with DISPLAY_VER == 10 is GLK. We don't need to
handle CNL explicitly in intel_ddi.c.
A lot of special code for CNL can be removed. There were some
__cnl.*() functions that were created to share the implementation
between ICL and CNL. Those are now embedded in the only caller, in ICL.
Remove code and rename functions/macros accordingly to use ICL prefix
for those that are still needed.

CNL is the only platform with GRAPHICS_VER == 10. With its removal we
don't need to handle that version anymore.
Also we can now reduce the max number of slices: the call to
intel_sseu_set_info() with the highest number of slices comes from SKL
and BDW with 3 slices. Recent platforms actually increase the
number of subslices so the number of slices remain 1.

PHY Layer testing
Source needs to write DPCD 103-106 after receiving a PHY request to change
swing/pre-emphasis after reading DPCD 206-207. This is especially needed if
there is a retimer between source and sink and the retimer implements AUX_CH
interception scheme to manage DP PHY settings (e.g. adjusting Swing/Pre-emphasis
equalization level) for DP output channel. If the source doesn't write to
DPCD 103-106, the retimer may not output the requested swing/pre-emphasis and
eventually we fail compliance.

DG2 has some changes to the expected modesetting sequences when compared
to gen12. Adjust our driver logic accordingly. Although the DP
sequence is pretty similar to TGL's, there are some steps that change,
so let's split the handling for that out into a separate function.
v2:
- Switch wait_for_us() -> _wait_for() so that we can parameterize the
timeout rather than duplicating the macro call. (Jani)

In discrete cards, the graphics driver shouldn't proceed with the probe
or resume unless PCODE indicated everything is done, including memory
training and gt bring up.
For this reason, the driver probe and resume paths needs to be blocked
until PCODE indicates it is done. Also, it needs to aborted if the
notification never arrives.
In general, the few miliseconds would be enough and the regular PCODE
recommendation for the timeout was 10 seconds. However there are some
rare cases where this initialization can take up to 1 minute. So,
PCODE has increased the recommendation to 3 minutes so we don't fully
block the device utilization when something just got delayed for
whatever reason. To be on the safest side, let's accept this
recommendation, since on the regular case it won't delay or block the
driver initialization and resume flows

The module init code is somewhat misplaced in i915_pci.c, since it
needs to pull in init/exit functions from every part of the driver and
pollutes the include list a lot.
Extract an i915_module.c file which pulls all the bits together, and
allows us to massively trim the include list of i915_pci.c.
The downside is that have to drop the error path check Jason added to
catch when we set up the pci driver too early. I think that risk is
acceptable for this pretty nice include.

The driver doesn't depend atm on the common mode timing generator
functionality (it would be used for some power saving feature and panel
timing synchronization), however DMC will corrupt the CMTG registers
across DC5 entry/exit sequences unless the CMTG clock gating is
disabled. This in turn can lead to at least the DPLL0/1 configuration
getting stuck at their last state, which means we can't reprogram them
to a new config.
Add the corresponding Bspec workaround to prevent the above.

ADL_P requires that we disable underrun recovery when downscaling (or
using the scaler for YUV420 pipe output), using DSC, or using PSR2.
Otherwise we should be able to enable the underrun recovery.
On DG2 we need to keep underrun recovery disabled at all times, but the
chicken bit in PIPE_CHICKEN has an inverted meaning (it's an enable bit
instead of disable).
v2:
- Reverse the condition (clear the disable bit when supported, set
disable bit when not supported).

Implement a simple static mapping algorithm of the i915 priority levels
(int, -1k to 1k exposed to user) to the 4 GuC levels. Mapping is as
follows:
i915 level < 0 -> GuC low level (3)
i915 level == 0 -> GuC normal level (2)
i915 level < INT_MAX -> GuC high level (1)
i915 level == INT_MAX -> GuC highest level (0)
We believe this mapping should cover the UMD use cases (3 distinct user
levels + 1 kernel level).
In addition to static mapping, a simple counter system is attached to
each context tracking the number of requests inflight on the context at
each level. This is needed as the GuC levels are per context while in
the i915 levels are per request.
v2:
(Daniele)
- Add BUILD_BUG_ON to enforce ordering of priority levels
- Add missing lockdep to guc_prio_fini
- Check for return before setting context registered flag
- Map DISPLAY priority or higher to highest guc prio
- Update comment for guc_prio

Some testing environments and some heavier tests are slower than
previous limits allowed for. For example, it can take multiple seconds
for the 'context has been reset' notification handler to reach the
'kill the requests' code in the 'active' version of the 'reset
engines' test. During which time the selftest gets bored, gives up
waiting and fails the test.
There is also an async thread that the selftest uses to pump work
through the hardware in parallel to the context that is marked for
reset. That also could get bored waiting for completions and kill the
test off.
Lastly, the flush at the of various test sections can also see
timeouts due to the large amount of work backed up. This is also true
of the live_hwsp_read test.

When GuC submission is enabled, the GuC controls engine resets. Rather
than explicitly triggering a reset, the driver must submit a hanging
context to GuC and wait for the reset to occur.
Conversely, one of the tests specifically sends hanging batches to the
engines but wants them to sit around until a manual reset of the full
GT (including GuC itself). That means disabling GuC based engine
resets to prevent those from killing the hanging batch too soon. So,
add support to the scheduling policy helper for disabling resets as
well as making them quicker!
In GuC submission mode, the 'is engine idle' test basically turns into
'is engine PM wakelock held'. Independently, there is a heartbeat
disable helper function that the tests use. For unexplained reasons,
this acquires the engine wakelock before disabling the heartbeat and
only releases it when re-enabling the heartbeat. As one of the tests
tries to do a wait for idle in the middle of a heartbeat disabled
section, it is therefore guaranteed to always fail. Added a 'no_pm'
variant of the heartbeat helper that allows the engine to be asleep
while also having heartbeats disabled.
