The last user of dev_priv->no_aux_handshake was removed in commit
3cf2efb1a7 ("Revert "drm/i915/dp: use VBT provided eDP params if

cd3e05836f drm/i915/kvmgt: Use struct_size() helper 
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, replace the following form:

sizeof(*sparse) + (nr_areas * sizeof(*sparse->areas)

with:

struct_size(sparse, areas, sparse->nr_areas)

and so on...

Also, notice that variable size is unnecessary, hence it is removed.

This code was detected with the help of Coccinelle.

5b5efdf79a drm/i915: Make debugfs/per_file_stats scale better 
Currently we walk the entire list of obj->vma for each obj within a file
to find the matching vma of this context. Since we know we are searching
for a particular vma bound to a user context, we can use the rbtree to
search for it rather than repeatedly walk everything.

c7302f2044 drm/i915: Defer final intel_wakeref_put to process context 
As we need to acquire a mutex to serialise the final
intel_wakeref_put, we need to ensure that we are in process context at
that time. However, we want to allow operation on the intel_wakeref from
inside timer and other hardirq context, which means that need to defer
that final put to a workqueue.

Inside the final wakeref puts, we are safe to operate in any context, as
we are simply marking up the HW and state tracking for the potential
sleep. It's only the serialisation with the potential sleeping getting
that requires careful wait avoidance. This allows us to retain the
immediate processing as before (we only need to sleep over the same
races as the current mutex_lock).

v2: Add a selftest to ensure we exercise the code while lockdep watches.
v3: That test was extremely loud and complained about many things!
v4: Not a whale!

Grr, missed one*. For using the legacy engine map, we should use
engine->legacy_idx. Ideally, we should know the intel_context in the
selftest and avoid all the fiddling around with unwanted GEM contexts.

* In my defence, the conflict was added in another patch after it was
tested by CI.

6aa3bef15d drm/i915: Get transcoder power domain before reading its register 
When getting the pipes attached to encoder if it is not a eDP encoder
it iterates over all pipes and read a transcoder register.
But it should not read a transcoder register before get its power
domain.

It was not a issue in gens older than 12 because if it only had
port A connected it would be attached to EDP and it would skip all
the transcoders readout, if it had more than one port connected,
pipe B would cause PG3 to be on and it contains all other
transcoders.

But on gen 12 there is no EDP transcoder so it is always iterating
over all pipes and if only one sink is connected, PG3 is kept off
and reading other transcoders registers would cause a
unclaimed read warning.

So here getting the power domain of the transcoder only if it is
enabled, otherwise it is not connected to the DDI.

f1c4d157ab drm/i915: Fix up the inverse mapping for default ctx->engines[] 
The order in which we store the engines inside default_engines() for the
legacy ctx->engines[] has to match the legacy I915_EXEC_RING selector
mapping in execbuf::user_map. If we present VCS2 as being the second
instance of the video engine, legacy userspace calls that I915_EXEC_BSD2
and so we need to insert it into the second video slot.

v2: Record the legacy mapping (hopefully we can remove this need in the
future)

The oa object manages the oa buffer and must be allocated when the user
intends to read performance counter snapshots. This can be achieved by
making the oa object part of the stream object which is allocated when a

Attributes in the oa object that are gen-specific are moved to the perf
object so that they can be initialized on driver load.

The split provides a better separation of the objects used in perf
implementation of i915 driver so that resources are allocated and
initialized only when needed.

2edda80db3 drm/i915: Rename engines to match their user interface 
During engine setup, we may find that some engines are fused off causing
a misalignment between internal names and the instances seen by users,
e.g. (I915_ENGINE_CLASS_VIDEO_DECODE, 1) may be vcs2 in hardware.
Normally this is invisible to the user, but a few debug interfaces (and
our own internal tracing) use the original HW name not the name the user
would expect as formed from their class:instance tuple. Replace our
internal name with the uabi name for consistency with, for example, error
states.

v2: Keep the pretty printing of class name in the selftest
