Pass around intel_atomic_state rather than drm_atomic_state.
This avoids some extra casts and annoing aliasing variables.

Currently, the i2c adapter is available only under DP connectors.
Add i2c symlink under hdmi connector pointing to i2c adapter in order to
make this behaviour consistent.
The initial motivation was to make igt i2c subtest
patch [1] work on all connectors.
[1]: https://patchwork.freedesktop.org/series/60357/
v2:
- Moved symlink remove to unregister (Ville)
- Clarified commit message (Jani)
- Changed WARN to DRM_ERROR (Jani)
- Minor codestyle changes proposed by Jani
v3: added blank line

Keep all the device-level PM management in intel_runtime_pm.h/c and move
all the display specific bits into their own file. Also add the new
header to Makefile.header-test.
Apart from the giant code move, the only difference is with the
intel_runtime_<get/put>_raw() functions, which are now exposed in the
header. The _put() version is also not conditionally compiled anymore
since it is ok to always pass the wakeref taken from the _get() to
__intel_runtime_pm_put (it is -1 if tracking is disabled).

Make sure the HW state of the port A combo PHY is correct wrt. the
IREFGEN setting. This will force a reprogramming during init or a WARN
during uninit if the setting is incorrect.
On my ICL RVP I haven't seen this check failing and leading to a forced
reinit/WARN, but let's add it still for consistency.

Currently, we try to report to the shrinker the precise number of
objects (pages) that are available to be reaped at this moment. This
requires searching all objects with allocated pages to see if they
fulfill the search criteria, and this count is performed quite
frequently. (The shrinker tries to free ~128 pages on each invocation,
before which we count all the objects; counting takes longer than
unbinding the objects!) If we take the pragmatic view that with
sufficient desire, all objects are eventually reapable (they become
inactive, or no longer used as framebuffer etc), we can simply return
the count of pinned pages maintained during get_pages/put_pages rather
than walk the lists every time.
The downside is that we may (slightly) over-report the number of
objects/pages we could shrink and so penalize ourselves by shrinking
more than required. This is mitigated by keeping the order in which we
shrink objects such that we avoid penalizing active and frequently used
objects, and if memory is so tight that we need to free them we would
need to anyway.
v2: Only expose shrinkable objects to the shrinker; a small reduction in
not considering stolen and foreign objects.
v3: Restore the tracking from a "backup" copy from before the gem/ split

Currently the purgeable objects, I915_MADV_DONTNEED, are mixed in the
normal bound/unbound lists. Every shrinker pass starts with an attempt
to purge from this set of unneeded objects, which entails us doing a
walk over both lists looking for any candidates. If there are none, and
since we are shrinking we can reasonably assume that the lists are
full!, this becomes a very slow futile walk.
If we separate out the purgeable objects into own list, this search then
becomes its own phase that is preferentially handled during shrinking.
Instead the cost becomes that we then need to filter the purgeable list
if we want to distinguish between bound and unbound objects.

The i915.alpha_support module parameter has caused some confusion along
the way. Add new i915.force_probe parameter to specify PCI IDs of
devices to probe, when the devices are recognized but not automatically
probed by the driver. The name is intended to reflect what the parameter
effectively does, avoiding any overloaded semantics of "alpha" and
"support".
The parameter supports "" to disable, "<pci-id>,[<pci-id>,...]" to
enable force probe for one or more devices, and "*" to enable force
probe for all known devices.
Also add new CONFIG_DRM_I915_FORCE_PROBE config option to replace the
DRM_I915_ALPHA_SUPPORT option. This defaults to "*" if
DRM_I915_ALPHA_SUPPORT=y.
Instead of replacing i915.alpha_support immediately, let the two coexist
for a while, with a deprecation message, for a transition period.

The normal behaviour is to periodically check for a mmio access error,
and once detected enable mmio access checking. However this is useless
if the error only occurs once during module load, and so we may miss
such errors in CI. To allow ourselves to catch them, allow CI to opt into
always enabling mmio debugging.

In order to support driver hot unbind, some cleanup operations, now
performed on PCI driver remove, must be called later, after all device
file descriptors are closed.
Split out those operations from the tail of pci_driver.remove()
callback and put them into drm_driver.release() which is called as soon
as all references to the driver are put. As a result, those cleanups
will be now run on last drm_dev_put(), either still called from
pci_driver.remove() if all device file descriptors are already closed,
or on last drm_release() file operation.

The plan is to use the blitter engine for async object clearing when
using local memory, but before we can move the worker to get_pages() we
have to first tame some more of our struct_mutex usage. With this in
mind we should be able to upstream the object clearing as some
selftests, which should serve as a guinea pig for the ongoing locking
rework and upcoming async get_pages() framework.

An interesting issue cropped with making the pagetables be allocated and
freed concurrently (i.e. removing their grandeous struct_mutex guard)
was that we would overflow the page stash. This happens when we have
multiple allocators grabbing WC pages such that we fill the vm's local
page stash and then when we free another page, the page stash is already
full and we overflow.
The fix is quite simple: to check for a full page stash before adding
another. This results in us keeping a vm local page stash around for
much longer, which is both a blessing and a curse.

This reverts commit 1ac159e23c2c ("drm/i915: Expand subslice mask"),
which kills ICL due to GEM_BUG_ON() sanity checks before CI even gets a
chance to do anything.
The commit exposes an issue in commit 1e40d4aea57b ("drm/i915/cnl:
Implement WaProgramMgsrForCorrectSliceSpecificMmioReads"), which will
also need to be addressed.
There's a proposed fix [1], but considering the seeming uncertainty with
the fix as well as the size of the regressing commit (in this context,
the one that actually brings down ICL), this warrants a revert to get
ICL working, and gives us time to get all of this right without
rushing. Even if this means shooting the messenger.

In intel_wakeref_auto, we use refcount_inc_not_zero to detect the first
use and initialise the timer. On doing so, we have to avoid using
refcount_inc on that zero count as the debug code flags that as an
error:
refcount_t: increment on 0; use-after-free.
Rearrange the code so that if we know the count is 0 and we are
initialising, we explicitly set it to 1.

Before we start prepping the system for an atomic modeset, wake the
device up. We then keep track of this wakeref until we complete the
atomic commit, so we hold keep the device awake for all potential HW
access, and do not allow the device to sleep with a pending modeset.

Currently, the subslice_mask runtime parameter is stored as an
array of subslices per slice. Expand the subslice mask array to
better match what is presented to userspace through the
I915_QUERY_TOPOLOGY_INFO ioctl. The index into this array is
then calculated:
slice * subslice stride + subslice index / 8
v2: fix spacing in set_sseu_info args
use set_sseu_info to initialize sseu data when building
device status in debugfs
rename variables in intel_engine_types.h to avoid checkpatch
warnings
v3: update headers in intel_sseu.h
v4: add const to some sseu_dev_info variables
use sseu->eu_stride for EU stride calculations
v5: address review comments from Tvrtko and Daniele
v6: remove extra space in intel_sseu_get_subslices

add GEM_BUG_ON to ensure user doesn't pass invalid ss_mask size
use printk formatted string for subslice mask
v7: remove string.h header and rebase

An old optimisation to reduce the number of atomics per batch sadly
relies on struct_mutex for coordination. In order to remove struct_mutex
from serialising object/context closing, always taking and releasing an
