V3D has a bit to set the line caps to be perpendicular to the line
rather than aligned to the edges of the framebuffer. I don’t know what
the disadvantages are of enabling this, but I noticed by experimentation

v3d: Add a lowering pass for line smoothing

When line smoothing is enabled, the driver now increases the width of
the line so that it can add some semi-transparent pixels to either side
of the line. A lowering pass is added which modifies the alpha component
of every write to fragment output 0 so that if the fragment is outside
the width of the line then the alpha is reduced. It additionally
discards fragments that are completely invisible. It might seem bad to
use discard on a tiled renderer but the assumption is that any bad
effects from using discard will also happen anyway because of enabling
alpha blending.

v2: Disable the line smoothing pass entirely when the framebuffer
    contains an integer colour output or one with no alpha channel.
    Calculate the coverage once upfront and store in a global variable
    instead of calculating each time an output write is modified. Also
    do the conditional discard once upfront.
v3: Don’t check whether the output buffer has an alpha channel. Only
    look at output 0. Use aa_line_width intrinsic instead of calculating
    the real line width in the shader. Clamp the coverage as part of the
    global variable, not per output write.

nir: add vec2_index_32bit_offset address format

For turnip, we use the "bindless" model on a6xx. Loads and stores with
the bindless model require a bindless base, which is an immediate field
in the instruction that selects between 5 different 64-bit "bindless
base registers", a 32-bit descriptor index that's added to the base, and
the usual 32-bit offset. The bindless base usually, but not always,
corresponds to the Vulkan descriptor set.  We can handle the case where
the base is non-constant by using a bunch of if-statements, to make it a
little easier in core NIR, and this seems to be what Qualcomm's driver
does too. Therefore, the pointer format we need to use in NIR has a vec2
index, for the bindless base and descriptor index. Plumb this format
through core NIR.

It also assumes all invocations will write all the levels, which is also

The comment about nir_lower_io_to_temporaries in lower_tess_ctrl_block is

shaders so the comment doesn't make sense.

This sets NIR_COMPACT_ARRAYS cap to avoid the glsl tess vec lowering with

By setting these two flags, we always take the unaligned,

turnip: make tiling config part of framebuffer state

Compute the tiling config at framebuffer creation time. A framebuffer will b
be re-used multiple times, so this will avoid having to re-calculate the
tiling config every time a command buffer is recorded.

The tiling config already couldn't use the render area's x1/y1 because of
hw binning, this move makes it so the render area isn't used at all for the
tiling config.

CI: reduce bandwidth for git pull

Over the last 7 days, git pulls represented a total of 1.7 TB.

On those 1.7 TB, we can see:
- ~300 GB for the CI farm on hetzner
- ~730 GB for the CI farm on packet.net
- ~680 GB for the rest of the world

We can not really change the rest of the world*, but we can
certainly reduce the egress costs towards our CI farms.

Right now, the gitlab runners are not doing a good job at
caching the git trees for the various jobs we make, and
we end up with a lot of cache-misses. A typical pipeline
ends up with a good 2.8GB of git pull data. (a compressed
archive of the mesa folder accounts for 280MB)

In this patch, we implemented what was suggested in
https://gitlab.com/gitlab-org/gitlab/-/issues/215591#note_334642576

- we host a brand new MinIO server on packet
- jobs can upload files on 2 locations:
  * git-cache/<namespace>/<project>/<branch-name>.tar.gz
  * artifacts/<namespace>/<project>/<pipeline-id>/
- the authorization is handled by gitlab with short tokens
  valid only for the time of the job is running
- whenever a job runs, the runner are configured to execute
  (eval) $CI_PRE_CLONE_SCRIPT
- this variable is set globally to download the current cache
  from the MinIO packet server, unpack it and replace the
  possibly out of date cache found on the runner
- then git fetch is run by the runner, and only the delta
  between the upstream tree and the local tree gets pulled.

We can rebuild the git cache in a schedule job (once a day
seems sufficient), and then we can stop the cache miss
entirely.

First results showed that instead of pulling 280MB of data
in my fork, I got a pull of only 250KB. That should help us.

* arguably, there are other farms in the rest of the world, so
hopefully we can change those too.
