7b1a8a5fce drm/xe: Fix definition of intel_wakeref_t
i915 defines it as unsigned long so Xe should do the same to avoid

315acff519 drm/xe: Fix warning on impossible condition
Having a different value for op is not possible: this is already kept
out of user-visible warning by the check in xe_wait_user_fence_ioctl()
if op > MAX_OP. The warning is useful as if this switch() is not update
when a new op is added, it should be triggered.

Fix warning as reported by 0-DAY CI Kernel:

	drivers/gpu/drm/xe/xe_wait_user_fence.c:46:2: warning: variable 'passed' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized]

de991b9af0 drm/xe: Remove ci-only GuC FW definitions
As part of the FW definitions, we declare each blob as required via the
MODULE_FIRMWARE() macro. This causes the initramfs update (or equivalent
process) to look for the blobs on disk when the kernel is installed;
therefore, we need to make sure that all FWs we define are available in
linux-firmware.

We currently don't plan to push the PVC blob to linux-firmware, while the
LNL one will only be pushed once we have machines in CI to test it, so we
need to remove them from the list for now.

e157f0f762 drm/xe: Fix build without CONFIG_FAULT_INJECTION
Ideally this header could be included without the CONFIG_FAULT_INJECTION
and it would take care itself for the includes it needs.
So, let's temporary workaround this by moving this below and including
only when CONFIG_FAULT_INJECTION is selected to avoid build breakages.

Another solution would be us including the linux/types.h as well, but
this creates unnecessary cases.

535881a8c5 drm/xe/uapi: Document the memory_region bitmask
The uAPI should stay generic in regarding to the bitmask. It is
the userspace responsibility to check for the type/class of the
memory, without any assumption.

Also add comments inside the code to explain how it is actually
constructed so we don't accidentally change the assignment of
the instance and the masks.

No functional change in this patch. It only explains and document
the memory_region masks. A further follow-up work with the
organization of all memory regions around struct xe_mem_regions
is desired, but not part of this patch.

Right now this is only checking if the engine list is sane and nothing

So, let's formalize that and only use this IOCTL to wait on the fence.

exec_queue_id member will help to user space to get proper error code

eb9702ad29 drm/xe: Allow num_batch_buffer / num_binds == 0 in IOCTLs
The idea being out-syncs can signal indicating all previous operations
on the bind queue are complete. An example use case of this would be
support for implementing vkQueueWaitIdle easily.

All in-syncs are waited on before signaling out-syncs. This is
implemented by forming a composite software fence of in-syncs and
installing this fence in the out-syncs and exec queue last fence slot.

The last fence must be added as a dependency for jobs on user exec
queues as it is possible for the last fence to be a composite software
fence (unordered, ioctl with zero bb or binds) rather than hardware
fence (ordered, previous job on queue).

06951c2ee7 drm/xe: Use NULL PTEs as scratch PTEs
Currently scratch PTEs are write-enabled and points to a single scratch
page. This has the side effect that buggy applications with out-of-bounds
memory accesses may not notice the bad access since what's written may
be read back.

Instead use NULL PTEs as scratch PTEs. These always return 0 when reading,
and writing has no effect. As a slight benefit, we can also use huge NULL
PTEs.

One drawback pointed out is that debugging may be hampered since previously
when inspecting the content of the scratch page, it might be possible to
detect writes to out-of-bound addresses and possibly also
from where the out-of-bounds address originated. However since the scratch
page-table structure is kept, it will be easy to add back the single
RW-enabled scratch page under a debug define if needed.

Also update the kerneldoc accordingly and move the function to create the
scratch page-tables from xe_pt.c to xe_pt.h since it is accessing
vm structure internals and this also makes it possible to make it static.

v2:
- Don't try to encode scratch PTEs larger than 1GiB.
- Move xe_pt_create_scratch(), Update kerneldoc.
v3:
- Rebase.

e84d716dd4 drm/xe: Restrict huge PTEs to 1GiB
Add a define for the highest level for which we can encode a huge PTE,
and use it for page-table building. Also update an assert that checks that
we don't try to encode for larger sizes.
