0ba6a0a23b intel/dev: Add supports_low_latency_hint to intel_device_info
Lets query if this feature is supported only once, also in the next
patches support for this feature will be added to Xe KMD.

ddf2aa3a4d build: avoid redefining unreachable() which is standard in C23
In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>

See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in

And this causes build errors when building for C23:

-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
                 from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
  123 | #define unreachable(str)    \
      |         ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
  456 | #define unreachable() (__builtin_unreachable ())
      |         ^~~~~~~~~~~
-----------------------------------------------------------------------

So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.

Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.

This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.

All the instances of the macro, including the definition, were updated
with the following command line:

  git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
  while read file; \
  do \
    sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
  done && \
  sed -e 's/#undef unreachable/#undef UNREACHABLE/g' -i src/intel/isl/isl_aux_info.c

e0a9ec34e7 intel: Add has_partial_mmap_offset to intel_device_info
Commit 3fc79582a1db ("drm/i915: Increase I915_PARAM_MMAP_GTT_VERSION version to indicate support for partial mmaps")
increased the I915_PARAM_MMAP_GTT_VERSION version, with that we can
detect what kernel version has the partial mmap fix or not and limit
the usage of this workaround.
This time o mmap will be used in memory pool, so here adding this
propertly to enable or not the feature.

3db8931d4a intel/i915: restrict the RAM size restrictions to Anv
Before commit b571ae6e7a ("intel: Make memory heaps consistent
between KMDs"), we had the following policy for reporting Sytem RAM
memory sizes:

- For OpenGL, we reported the total available RAM.
- For Vulkan, we reported the total available RAM as:
  - 50% of the total RAM if the total RAM was <= 4GB,
  - 75% otherwise
  - In addition, the Memory Budget (for VK_EXT_memory_budget) is 90%
    of the "free" memory, which can be an extra 10% off of the 50% or
    75%.

When xe.ko was added, one key difference was noted: while i915.ko
reported the "real" RAM memory sizes in its ioctls, xe.ko reported
only 50% of the system RAM as available. Because of that (and other
reasons, see this discussion on MR 28513), commit b571ae6e7a decided
to unify the behavior by changing the Anv i915.ko rule to "always 50%"
instead of "50% or 75%". This also changed the Iris rule to 50%
instead of 100%.

In my research, I couldn't find any reason why this restriction should
also apply to Iris, so here we revert back to handling these size
restrictions on Anv only.

6a0f2dd44b intel/dev: Fix max_cs_threads value on simulator
intel_device_info_update_after_hwconfig() updates max_cs_threads
based on max_eus_per_subslice and num_thread_per_eu but in some
platforms simulator the hwconfig don't have the
INTEL_HWCONFIG_MAX_NUM_EU_PER_DSS value, causing max_cs_threads to
be set to a wrong value and then causing issues when programing
CFE_STATE with a invalid value.

Fortunately we can also get max_eus_per_subslice from topology query,
so here moving the hwconfig query and
intel_device_info_update_after_hwconfig() call to after topology.

b571ae6e7a intel: Make memory heaps consistent between KMDs
Xe KMD reports SMEM size as half of RAM while i915 returns the whole
RAM size, so to keep it consistent here adjusting the values
returned by i915 KMD.

The free i915 SMEM also needs to be ajusted but as this is needed by
both KMDs because KMD uAPIs only reports free memory for applications
running elevated privileges, so this was moved to
intel_device_info_ajust_memory() to be shared by both KMD backends.

sram.mappable.size asserts had to be removed from i915 code paths
because of this adjustment.

anv_compute_sys_heap_size() was dropped in ANV and reduce in HASVK
because adjustments are now done in intel/dev level.
