When I915_PARAM_HAS_CONTEXT_FREQ_HINT is not supported the
intel_ioctl(fd, DRM_IOCTL_I915_GETPARAM, &gp) will return -1 and that
will cause i915_gem_get_param() to return false.
val will be different than 1 when not using GuC submission, so we are
forcing val check to ensure this holds good in platforms that doesn't
support GuC submission.

We were generating odd instructions like:
math inv(8) g93<1>HF g85<8,8,1>HF null<8,8,1>F { align1 1Q @7 $4 };
It's unclear whether the type of the null operand matters, but sometimes
these things don't get ignored properly. Out of caution, retype the
null source to match the actual operand's type. It'll at least look
less surprising in assembly dumps.

So for this entry we want the CPU mapping to be WC but GPU caches
can be WB.
This way GPU don't need to snoop to CPU caches and at the end of
workloads L3 cache is flushed, so CPU access is coherent after get
the signal that workload was finished.
With this the transient(XD) L3 flushes will only affect displayable
buffers.

My initial understating was that L3_CACHE_POLICY would be the CPU
caching mode but that has nothing to do with CPU caching, it is the
GPU caching mode.
Due this miss understating we were using a not optimal PAT index that
will be fixed in the next patches, so to avoid such issues in future
adding comments to intel_device_info_pat_entry struct.

Commit 94989b45a5 ("anv,driconf: Add fake non device local memory WA
for Total War: Warhammer 3") implemented a workaround to make
Warhammer 3 work on ADL, but the game still doesn't work on LNL, which
uses xe.ko, and MTL, which uses i915.ko: it still fails at launch
claiming it couldn't allocate memory.
So in this implementation, instead of clearing DEVICE_LOCAL_BIT we
just duplicate our memory types, one having the bit and one not
having.
v2:
- Check for VK_MAX_MEMORY_TYPES (José)
- Invert the order of the memory types (José)
- Fix white space issue (José)
v3:
- Comment our non-spec-compliance (José)
- Remove useless lines (José)

Handle '\n' when inside the MSGDESC start condition,
otherwise the lexer would apply its default rule (write
to stdout).
Without that, newlines were "leaking" to the output when
parsing a multiple line "MsgDesc". E.g. given the file
example.asm below
```
send(8) nullUD g126UD nullUD 0x02000000 0x00000000
thread_spawner MsgDesc: mlen 1 ex_mlen 0 rlen 0
{ align1 WE_all 1Q @1 EOT };
```
the assembler would produce one extra newline
```
$ brw_asm -t hex -g tgl example.asm
31 01 03 80 04 00 00 00 0c 7e 00 70 00 00 00 00

Commit f695a9fed2 moved the 64-bit float <-> 16-bit float conversion
splitting into a core NIR pass, so the code remaining here is only
needed for 64-bit integer types.
Presumably in an attempt to remove the float handling, it replaced
simple bit_size == 64 checks with this expression:
(full_type & (nir_type_int64 | nir_type_uint64))
I believe that the intended expression was:
(full_type == nir_type_int64 || full_type == nir_type_uint64)
Unfortunately, the former is incorrect. Any integer or unsigned
NIR type would trigger the former expression. For example:
nir_type_uint32 & (nir_type_int64 | nir_type_uint64) => nir_type_uint
This meant that we were splitting e.g. u2f16 on 32-bit unsigned types
into u2f32 and f2f16, when we can easily natively handle that case.
To fix this, we go back to simple bit_size == 64 checks. This pass is
already run after nir_lower_fp16_casts which will split the float case,
so we will never see it here.
fossil-db on Alchemist shows a -1.14% reduction in affected shaders for
google-meet-clvk shaders. In another ChromeOS workload, it improves
performance by around 8% on Meteorlake.
Thanks to Sushma Venkatesh Reddy for finding this performance issue!
