isam.v is a version of isam that can load multiple components from IBOs.
It uses some bits that are used for different purposes in other tex
instructions:
- bit 50 (.v): .s elsewhere
- bit 53 (indicates whether an immediate offset is used): .p elsewhere
- bit 18 (.1d when not set, has to be set for .v): 0 elsewhere
For this reason, the bitset hierarchy for cat5 had to be reordered a
bit.
The immediate offset is encoded as an extra (immed) source register and
an instruction flag (to be able to make the distinction between offset
zero and no offset, although this might not be useful).
This also adds a flag for the .1d field. Since this bit is active-low,
this flag has inverted semantics: setting it will make .1d inactive.
Note that some existing disassembler tests for isam had to be updated
because the bit is never set and this is now disassembled as .1d. This
matches the blob's disassembler.

Rebasing around this patch has been a significant burden for development.
Staging patches to asahi/mesa helps somewhat but 1. it's still really
frustrating to have this much divergence with upstream, and 2. ideally we
wouldn't have to do that.
The kernel upstreaming is stalled for various reasons. This patch adds
compile-only code to speak the unstable Linux UAPI for the SOLE purpose of
reducing my rebase pain... NOT to actually work.
It is NOT for users OR distro maintainers. asahi will refuse to probe on
upstream Mesa to protect against regressions. The uapi is NOT STABLE and
upstream Mesa CANNOT be used with it. Attempting to bypass this WILL give you a
broken system.
This patch employs several layers of deterrents against system-breaking
enablement. With a lot of warning text at the relevant sites. Hopefully that is
good enough to prevent people from breaking systems. And if people brazenly
ignore all of the above ... they get to pick up the pieces.
You have been warned.
---
There is significant prior art for Mesa including downstream kernel uapi
supports in-tree:
* powervr (downstream android driver)
* turnip (downstream kgsl android driver)
* asahi ... ironically (prop macOS kernel driver)
* maybe vc4?
Linux is only special because of distros shipping tagged Mesa releases. The
several layers of guards here guarantee that no tagged Mesa release would
possibly probe even on an asahi downstream kernel. A distro would need a
significant scary patch to make it probe. If/when it breaks, that's on them
and they pick up the pieces.
I make a stability guarantee ONLY for Fedora Asahi Remix -- where we push
packages for both a downstream kernel and Mesa in tandem, while we patiently
wait for upstreaming -- and that is *it*. It will be a nice future when this all
works upstream, but unfortunately we're not there yet.

This gets rid of most of the pointless bitfields and also moves away from
unsigned, which we really should stop using :)

If we have an array of multi-planar descriptors, buffer_list was
incorrectly incremented and this could have overwritten some BO entries.
In practice, this situation should be very rare because most of the
applications enable the global BO list.

This is what the old GL driver did and appears to be what the blob does
as well. They should pipeline much better than full buffer re-binds
which appear to be causing stalling issues inside the GPU.

We want everything that touches the root table to go through ldc path

Looking at binding_layout->desc_type is sketchy in the face of mutable
descriptors. It's safer for load_descriptor() to just return the
descriptor. load_descriptor_for_idx_intrin() knows about the
descriptor's actual shader usage and we can do the optimization there.
This isn't actually a bug fix. The optimization just didn't happen in
the presence of mutable descriptors.
