75452f611e intel/common: Only set op mask on instructions in decoder
When a default value of a struct's field, which is in the
higher half of the first dword, is specified in a gen xml
file, setting op mask makes decoder treat the field as a
header (intel_field_is_header()). As a result, it won't
output the field in batch dump. This is not a common case
but can happen once a gen xml file includes such fields.

The op mask is only meaningful to instructions, so we fix
the above issue by not setting op mask of structs (also
registers).

ce07aabab1 meson: Key whether to build batch decoder on expat
Instead of on Android. Which allows an end user to turn off expat
without breaking or disabling Intel support. I've additionally
refactored to separate expat and xmlconfig a bit more in the root
meson.build

This does make expat a hard dependency for building Intel tools, despite
the fact that only aubinator actually requires it. This simplifies the
build for the common case, and in the event that someone wants to build
the Intel tools and doesn't have libexpat, they can fall back to the
meson wrap for expat instead.

e358173fbf iris: Add GET_PARAM for protected context capability support
With MTL onwards, creating protected contexts too early
may block for a longer period. To prevent that, use the new
kernel GET_PARAM:I915_PARAM_PXP_STATUS interface to get the
status of PXP support immediately without blocking.

Using this same interface, we can also wait for platform
dependency readiness before attempting to create a protected
context. Use a longer timeout when user explicitly requests
for protected context as the kernel assures readiness will be
achieved.

55ba4575be intel: INTEL_MEASURE cpu mode
INTEL_MEASURE normally measures timing of GPU events. However, it
is sometimes useful to instead measure when these gfx API calls
were requested of the driver. INTEL_MEASURE cpu can be used in
in conjunction with other driver debug capabilities, like
INTEL_DEBUG=pc for analyzing stalls/flushes or when debugger is
attached, to track which frame you're currently on or where in
the frame you're at.

Initial commit, without plumbing into anv/iris.

"INTEL_MEASURE=cpu" will collect a cpu timestamp for each
INTEL_MEASURE event instead of GPU timestamps.

a result improves vk_meshlet_cadscene performance by up to 2%,
depending on the model.

a364f23a6c intel: Make gen12 URB space reservation dependent on compute engine presence
Tigerlake PRM: Volume 2c: Command Reference: Registers Part 2 - Registers M through Z
RCU_MODE :: Compute Engine Enable

   This bit indicates if Compute Engine (a.k.a Dual Context or Multi
   Context) is enabled or not. This bit must be treated as global
   control for enabling and disabling of compute engine. Hardware
   allocates required resources for the compute engine based on this
   bit.
   ....
   HW reserves 4KB of URB space...

Right now no gen12 platform has Dual Context enabled in kernel side,
exposing a compute engine but that can change, so here adding
has_compute_engine to intel_device_info and only reserving URB space
if compute engine is available.

While at it also fixing the error path when pb_slabs_init() fails.

e050a00b9f intel/common: Move i915 files to i915 folder
Following the organization done in intel/dev and intel/vulkan.

Probably due to some rebase issue we had a duplicated copyright header
in intel_gem_i915.h that is being removed in here too.
