I used an old version of the script to generate the notes, which didn't
generate this. It is being kept separate instead of being squashed so
that the commits on the 23.0 branch and those on main match

The previous lowering was insufficient in two areas:
* No support for indirection. This is required for dynamically indexing into
UBOs, SSBOS, etc in OpenGL ES 3.2
* Only a single table supported. Multiple tables are required to implement
indirect dispatch/draws efficiently, in order to bind the indirect buffer as
uniforms.
The first problem is addressed here by reworking the lowering of
system values to happen in NIR, decoupled from the uniform register assignment
details, such that we can handle 1:n lowerings in a straightforward way.
Namely, indirect sysvals are lowered to indirect memory loads relative to the
base address of the sysval table, where the table address is itself pushed as a
(direct) sysval.
The second problem is addressed in this patch by generalizing to multiple
uniform tables.

Strictly, this extension was already advertised, but it didn't seem nice to mark
it DONE when there was no sync support in the driver whatsoever. Mark it done
now that we do have proper explicit sync (well, in conjunction with the "add
Linux UAPI" patches that are blocked on getting the kernel driver upstream, but
that's needed for *any* of these extensions to be there!)

Now that turnip can support multiple kernel-mode drivers in a single
build, re-work the meson option to have a single list of KMDs, rather
than special options to enable kgsl for turnip or virtio for gallium.
It is temporarily a bit awkward as gallium does not yet support kgsl
and turnip does not yet support virtio. But both of those are planned
or in-progress, so long term a single list is the most sensible option.
TODO freedreno/drm support to build with only virtio support.

Seems this document has moved since last we updated this link. But
instead of chasing the exact CDN link, let's link to the document on
Intel's website. There's both a download-link there, as well as the
ability to read the document online.

The script is broken, and nobody noticed so it wasn't used much.
Meson has had support for printing the options by pointing to the source
dir for a while (not sure the exact version though) so I think we can
just recommend users do that.

The graphics pipeline library implementation in RADV has been
improved considerably lately.
There is still a bit of work for caching individual libraries
and optimized (LTO) pipelines but I think overall it seems good
enough to stop reporting it as experimental and suboptimal.

These implement gl_ClipDistance in hardware, avoiding the fragment shader
lowering. Unfortunately, they can't be disabled on a per-plane basis and they
can't be interpolated, so using them for OpenGL would still require a bunch of
extra lowering steps. Still, we should document the hardware and the caveats.

Whenever a single file mesa-db cache hits max size limit, a half of cache
is evicted and the cache file is defragmented. The downside of this eviction
strategy is that it causes high disk IO usage during eviction if mesa-db
cache file size is large.
In order to mitigate this downside, we will split mesa-db into multiple
part such that only one part will be evicted at a time. Each part will be
an individual single file mesa-db cache, like a DB shard. The new multipart
mesa-db cache will merge the parts into a single virtual cache.
This patch introduces two new environment variables:
1. MESA_DISK_CACHE_DATABASE_NUM_PARTS:
Controls number of mesa-db cache file parts. By default 50 parts will be
created. The old pre-multipart mesa-db cache files will be auto-removed
if they exist, i.e. Mesa will switch to the new DB version automatically.
2. MESA_DISK_CACHE_DATABASE_EVICTION_SCORE_2X_PERIOD:
Controls the eviction score doubling time period. The evicted DB part
selection is based on cache entries size weighted by 'last_access_time' of
the entries. By default the cache eviction score is doubled for each month
of cache entry age, i.e. for two equally sized entries where one entry is
older by one month than the other, the older entry will have x2 eviction
score than the other entry. Database part with a highest total eviction
score is selected for eviction.
This patch brings x40 performance improvement of cache eviction time using
multipart cache vs a single file cache due to a smaller eviction portions
and more optimized eviction algorithm.

Allow the loading process to affect driconf option matching without
changing the behavior throughout mesa common code or leaking the name of
the loading process to logs, artifact storage, or in sub-thread naming,
as can be the case with the broader MESA_PROCESS_NAME override.
This new MESA_DRICONF_EXECUTABLE_OVERRIDE takes higher precedence over
MESA_PROCESS_NAME in the case where both are set.
