It used to be handy that we only had a couple of headers, but over time
i915_drv.h has become unwieldy. Extract declarations to a separate
header file corresponding to the implementation module, clarifying the
modularity of the driver.
Ensure the new header is self-contained, and do so with minimal further
includes, using forward declarations as needed. Include the new header
only where needed, and sort the modified include directives while at it
and as needed.
No functional changes.

Looks like VBT contains again the wrong information about a port's TypeC
legacy vs. DP-alt/TBT-alt type. There is no further issues after we
notice this and fix it up, so tune down the WARN to be a a DRM_ERROR.
This also avoids CI tainting the kernel and stopping the test run.

- Update also code coment accordingly. (Jani)

We've already committed to enabling audio when intel_audio_codec_enable()
is called. We can't back out even if the ELD has turned sour in the
meantime. So just spew some debug log and plow ahead. Otherwise the
state checker gets unhappy when audio isn't enabled when it is
expected to be.
I suppose we really ought to precompute the ELD as well, but
let's just toss in a FIXME for the future.

Currently due to regression CI machine displays show corrupt picture.
Problem is when CDCLK is as low as 79200, picture gets unstable, while
DSI and DE pll values were confirmed to be correct. Limiting to 158400
as agreed with Ville.
We could not come up with any better solution yet, as PLL divider values
both for MIPI(DSI PLL) and CDCLK(DE PLL) are correct, however seems that
due to some boundary conditions, when clocking is too low we get wrong
timings for DSI display. Similar workaround exists for VLV though, so
just took similar condition into use. At least that way GLK platform
will start to be usable again, with current drm-tip.
v2: Fixed commit subject as suggested.
v3: Added generic bugs(crc failures, screen not init
for GLK DSI which might be affected).
v4: Added references tag for bugs affected.

The workqueue code complains viciously if we try to queue more work onto
the queue while attampting to drain it. As we asynchronously free
objects and defer their enqueuing with RCU, it is quite tricky to
quiesce the system before attempting to drain the workqueue. Yet drain
we must to ensure that the worker is idle before unloading the module.
Give the freed object drain 3 whole passes with multiple rcu_barrier()
to give the defer freeing of several levels each protected by RCU and
needing a grace period before its parent can be freed, ultimately
resulting in a GEM object being freed after another RCU period.
A consequence is that it will make module unload even slower.

The pipe has a special HDR mode with higher precision when only
HDR planes are active. Let's use it.
Curiously this fixes the kms_color gamma/degamma tests when
using a HDR plane, which is always the case unless one hacks
the test to use an SDR plane. If one does hack the test to use
an SDR plane it does pass already.
I have no actual explanation how the output after the gamma
LUT can be different between the two modes. The way the tests
are written should mean that the output should be identical
between the solid color vs. the gradient. But clearly that
somehow doesn't hold true for the HDR planes in non-HDR pipe
mode. Anyways, as long as we stick to one type of plane the
test should produce sensible results now.

Add more headers to the header test list:
* i915_drv.h
* i915_params.h
* i915_reg.h
* intel_drv.h
* intel_uncore.h
Happily they already are self-contained, but keep them that way.

Separate the two comments: one is a workaround and the other is a sanity
check. We could just compare != 1, but let's treat them differently due
to having different meaning.

Reorder if/else so we check for gen >= 11 first, similar to most of
other checks in the driver.

At some point the spec was changed and we never updated the numbers to
match it. Let's try once more to keep them in sync.

WaEnableStateCacheRedirectToCS context workaround configures the L3 cache
to benefit 3d workloads but media has different requirements.
Remove the workaround and whitelist the register to allow any userspace
configure the behaviour to their liking.
v2:
* Remove the workaround apart from adding the whitelist.

If the context has not been used yet, it needs no barrier, and in the
process fix up the selftest in mock_contexts.

Having transitioned GEM over to using intel_context as its primary means
of tracking the GEM context and engine combined and using
i915_request_create(), we can move the older i915_request_alloc()
helper function into selftests/ where the remaining users are confined.

We no longer need to track the active intel_contexts within each engine,
allowing us to drop a tricky mutex_lock from inside unpin (which may
occur inside fs_reclaim).

We switched to a tree of per-engine HW context to accommodate the
introduction of virtual engines. However, we plan to also support
multiple instances of the same engine within the GEM context, defeating
our use of the engine as a key to looking up the HW context. Just
allocate a logical per-engine instance and always use an index into the
ctx->engines[]. Later on, this ctx->engines[] may be replaced by a user
specified map.
v2: Add for_each_gem_engine() helper to iterator within the engines lock
v3: intel_context_create_request() helper
v4: s/unsigned long/unsigned int/ 4 billion engines is quite enough.
v5: Push iterator locking to caller

initialising the pinned kernel contexts, so split the vfunc setup from
the engine initialisation and call it earlier.
