treewide: Replace zero-length arrays with flexible-array members
Additional workarounds are required once we start exposing CCS engines.
Note that we have a number of workarounds that update registers in the
shared render/compute reset domain. Historically we've just added such
registers to the RCS engine's workaround list. But going forward we
should be more careful to place such workarounds on a wa_list for an
engine that definitely exists and is not fused off (e.g., a platform
with no RCS would never apply the RCS wa_list). We'll keep
rcs_engine_wa_init() focused on RCS-specific workarounds that only need
to be applied if the RCS engine is present. A separate
general_render_compute_wa_init() function will be used to define
workarounds that touch registers in the shared render/compute reset
domain and that we need to apply regardless of what render and/or
compute engines actually exist. Any workarounds defined in this new
function will internally be added to the first present RCS or CCS
engine's workaround list to ensure they get applied (and only get
applied once rather than being needlessly re-applied several times).

HW resources are divided across the active CCS engines at the compute
slice level, with each CCS having priority on one of the cslices.
If a compute slice has no enabled DSS, its paired compute engine is not
usable in full parallel execution because the other ones already fully
saturate the HW, so consider it fused off.
v2 (José):
- moved it to its own function
- fixed definition of ccs_mask
v3 (Matt):
- Replace fls() condition with a simple IP version test
v4 (Matt):
- Don't try to calculate a ccs_mask using
intel_slicemask_from_dssmask() until we've determined that we're
running on an Xe_HP platform where the logic makes sense (and won't
overflow).

It is possible for reset notifications to arrive for a context that is
in the process of being banned. So don't flag these as an error, just
report it as informational (because it is still useful to know that
resets are happening even if they are being ignored).

A flag query helper was actually writing to the flags word rather than
just reading. Fix that. Also update the function's comment as it was
out of date.
NB: No need for a 'Fixes' tag. The test was only ever used inside a
BUG_ON during context registration. Rather than asserting that the
condition was true, it was making the condition true. So, in theory,
there was no consequence because we should never have hit a BUG_ON
anyway. Which means the write should always have been a no-op.

It's unclear what reference the initial vma kref reference refers to.
A vma can have multiple weak references, the object vma list,
the vm's bound list and the GT's closed_list, and the initial vma
reference can be put from lookups of all these lists.
With the current implementation this means
that any holder of yet another vma refcount (currently only
i915_gem_object_unbind()) needs to be holding two of either
*) An object refcount,
*) A vm open count
*) A vma open count
in order for us to not risk leaking a reference by having the
initial vma reference being put twice.
Address this by re-introducing i915_vma_destroy() which removes all
weak references of the vma and *then* puts the initial vma refcount.
This makes a strong vma reference hold on to the vma unconditionally.
Perhaps a better name would be i915_vma_revoke() or i915_vma_zombify(),
since other callers may still hold a refcount, but with the prospect of
being able to replace the vma refcount with the object lock in the near
future, let's stick with i915_vma_destroy().
Finally this commit fixes a race in that previously i915_vma_release() and
now i915_vma_destroy() could destroy a vma without taking the vm->mutex
after an advisory check that the vma mm_node was not allocated.
This would race with the ungrab_vma() function creating a trace similar
to the below one. This was fixed in one of the __i915_vma_put() callsites
in
commit bc1922e5d3 ("drm/i915: Fix a race between vma / object destruction and unbinding")
but although not seemingly triggered by CI, that
is not sufficient. This patch is needed to fix that properly.

For local-memory objects we need to align the GTT addresses
to 64K, both for the ppgtt and ggtt.
We need to support vm->min_alignment > 4K, depending
on the vm itself and the type of object we are inserting.
With this in mind update the GTT selftests to take this
into account.
For compact-pt we further align and pad lmem object GTT addresses
to 2MB to ensure PDEs contain consistent page sizes as
required by the HW.
v3:
* use needs_compact_pt flag to discriminate between
64K and 64K with compact-pt
* add i915_vm_obj_min_alignment
* use i915_vm_obj_min_alignment to round up vma reservation
if compact-pt instead of hard coding
v5:
* fix i915_vm_obj_min_alignment for internal objects which
have no memory region
v6:
* tiled_blits_create correctly pick largest required alignment
v8:
* i915_vm_min_alignment protect against array overflow for mock region
