0cabcf83b2 drm/amdgpu: Track IRQ state in local device state 
Replace usage of struct drm_device.irq_enabled with the driver's
own state field struct amdgpu_device.irq.installed. The field in
the DRM device structure is considered legacy and should not be
used by KMS drivers.

1988e0d841 drm/panel: nt35510: Do not fail if DSI read fails 
Failing to read the MTP over DSI should not bring down the
system and make us bail out from using the display, it turns
out that this happens when toggling the display off and on,
and that write is often still working so the display output
is just fine. Printing an error is enough.

Tested by killing the Gnome session repeatedly on the
Samsung Skomer.

c90c4c6574 drm/i915: Reinstate the mmap ioctl for some platforms 
Reinstate the mmap ioctl for all current integrated platforms.
The intention was really to have it disabled for discrete graphics
where we enforce a single mmap mode.

This was reported to break ADL-P with the media stack, which was not the
intention. Although longer term we do still plan to sunset this ioctl
even for integrated, in favour of using mmap_offset instead.

a193477271 drm/i915/dsc: abstract helpers to get bigjoiner primary/secondary crtc 
Add a single point of truth for figuring out the primary/secondary crtc
for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple
places.

Also fix the pipe validity checks to properly take non-contiguous pipes
into account. The current checks may theoretically overflow
i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused
off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on
the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1.

Prefer primary/secondary terminology going forward.

v2:
- Improved abstractions for pipe validity etc.

3b5ac97ad4 drm/sched: Declare entity idle only after HW submission 
The panfrost driver tries to kill in-flight jobs on FD close after
destroying the FD scheduler entities. For this to work properly, we
need to make sure the jobs popped from the scheduler entities have
been queued at the HW level before declaring the entity idle, otherwise
we might iterate over a list that doesn't contain those jobs.

Since we are already loop through the levels to sanitize them, mark what
is the real max_level so it can be used in subsequent loop. This makes
it simpler to later add the adjustment latency to "valid levels". No

Instead spec says to add 3usec (as opposed to 2) to each valid level

So set wm_lv_0_adjust_needed to false for DISPLAY_VER() >= 12 and set
the proper adjustment value when handling WaWmMemoryReadLatency.

32b7cf51a4 drm/i915/ttm: Use TTM for system memory 
For discrete, use TTM for both cached and WC system memory. That means
we currently rely on the TTM memory accounting / shrinker. For cached
system memory we should consider remaining shmem-backed, which can be
implemented from our ttm_tt_populate callback. We can then also reuse our
own very elaborate shrinker for that memory.

If an object is evicted to a gem allowable region, we will now consider
the object migrated, and we flip the gem region and move the object to a
different region list. Since we are now changing gem regions, we can't
any longer rely on the CONTIGUOUS flag being set based on the region
min page size, so remove that flag update. If we want to reintroduce it,
we need to put it in the mutable flags.

3c2b8f326e drm/i915/ttm: Adjust gem flags and caching settings after a move 
After a TTM move or object init we need to update the i915 gem flags and
caching settings to reflect the new placement. Currently caching settings
are not changed during the lifetime of an object, although that might
change moving forward if we run into performance issues or issues with
WC system page allocations.
Also introduce gpu_binds_iomem() and cpu_maps_iomem() to clean up the
various ways we previously used to detect this.
Finally, initialize the TTM object reserved to be able to update
flags and caching before anyone else gets hold of the object.

0ff375759f drm/i915: Update object placement flags to be mutable 
The object ops i915_GEM_OBJECT_HAS_IOMEM and the object
I915_BO_ALLOC_STRUCT_PAGE flags are considered immutable by
much of our code. Introduce a new mem_flags member to hold these
and make sure checks for these flags being set are either done
under the object lock or with pages properly pinned. The flags
will change during migration under the object lock.

40cfc7fce4 drm/simple-helper: drm_gem_simple_display_pipe_prepare_fb as default 
It's tedious to review this all the time, and my audit showed that
arcpgu actually forgot to set this.

Make this the default and stop worrying.

Again I sprinkled WARN_ON_ONCE on top to make sure we don't have
strange combinations of hooks: cleanup_fb without prepare_fb doesn't
make sense, and since simpler drivers are all new they better be GEM
based drivers.

v2: Warn and bail when it's _not_ a GEM driver (Noralf)

v3: It's neither ... nor, not not (Sam)

7d30963fd1 drm/atomic-helper: make drm_gem_plane_helper_prepare_fb the default 
There's a bunch of atomic drivers who don't do this quite correctly,
luckily most of them aren't in wide use or people would have noticed
the tearing.

By making this the default we avoid the constant audit pain and can
additionally remove a ton of lines from vfuncs for a bit more clarity
in smaller drivers.

While at it complain if there's a cleanup_fb hook but no prepare_fb
hook, because that makes no sense. I haven't found any driver which
violates this, but better safe than sorry.

Subsequent patches will reap the benefits.

v2: It's neither ... nor, not not (Sam)
