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.

Rename supports_mmio_ext and supports_usm to use a has_ prefix so the
flags are grouped together. This settles on just one variant for
positive info matching ("has_") and one for negative ("skip_").
Also make sure the has_* flags are grouped together in xe_pci.c.

Disable dynamic HW load balancing of compute resource assignment
to engines and instead enabled fixed mode of mapping compute
resources to engines on all platforms with more than one compute
engine.
By default enable only one CCS engine with all compute slices
assigned to it. This is the desired configuration for common
workloads.
PVC platform supports only the fixed CCS mode (workaround 16016805146).
v2: Rebase, make it platform agnostic
v3: Minor code refactoring

Migration primarily focuses on the memory associated with a tile, so it
makes more sense to track this at the tile level (especially since the
driver was already skipping migration operations on media GTs).
Note that the blitter engine used to perform the migration always lives
in the tile's primary GT today. In theory that could change if media
GTs ever start including blitter engines in the future, but we can
extend the design if/when that happens in the future.

Rather than a backpointer to the xe_device, a GT should have a
backpointer to its tile (which can then be used to lookup the device if
necessary).
The gt_to_xe() helper macro (which moves from xe_gt.h to xe_gt_types.h)
can and should still be used to jump directly from an xe_gt to
xe_device.

- Fix kunit test build
- Move a couple changes to the previous patch. (Lucas)

Replace the inline function with a _Generic() so gt_to_xe() can work
with a const struct xe_gt*, which leads to a const struct xe *.
This allows a const gt being passed around and when the xe device is
needed, compiler won't issue a warning that calling gt_to_xe() would
discard the const. Rather, just propagate the const to the xe pointer
being returned.

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).
The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).
The new Xe driver leverages a lot from i915.
As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.
This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:
