[ConstantFolding] Fix dropped bits in non-integer-ratio bitcast with undef lane (#202282)
When constant-folding a vector bitcast(e.g. <4 x i24> -> <3 x i32>), an
undef source element inserted a DstBitSize-wide zero placeholder into
the bit buffer. This could clobber defined source element, producing a
wrong result on big-endian targets.
Fix by inserting SrcBitSize-wide zero instead.

[mlir][spirv] Add Arm.ExperimentalMLOperations.1 extended inst set (#202283)
This instruction set provides a mechanism to encode experimental ML
operations in SPIR-V modules. Such instructions are encoded via the
single CALL operator in the instruction set by specifying an op_code and
customized inputs values.

[CI][Offload] Fix offload depends on openmp (#202541)
It appears that Offload depends on OpenMP. Thus, enable OpenMP as a
runtime to test when offload has changes.
forgejo-cli: Import forgejo-cli-0.5.0 as wip/forgejo-cli
fj, a CLI client for Forgejo akin to gh, glab, or tea!
You can...
- Open, edit, comment on, close issues
- Create and merge pull requests
- Easily create AGit pull requests, no need to fork!
- Create, star, watch, and edit repositories
- Manage organizations and teams
- Publish new releases
...all from the command line!
fj doesn't try to replace your usage of git, it's meant to work
alongside it. It handles all the Forgejo-specific things that git
doesn't.
Remove stale ARC graph names from reporting API
`reporting.get_data` accepted three graph names — `arcrate`, `arcactualrate`, `arcresult` — whose backing plugin classes were deleted during the ZFS netdata plugin rewrite. The Pydantic `Literal` and the in-memory `__graphs` dict drifted out of sync, so passing any of them crashed `netdata_get_data` with an uncaught `KeyError`.
Removed the dead names from `GraphIdentifier.name`'s `Literal` and docstring in both `v26_0_0/reporting.py` and `v27_0_0/reporting.py`. Added a `ReportingNetdataGetDataArgs.from_previous` on each so legacy WS clients walking the adapter chain get the dead entries silently filtered instead of a hard rejection at the final v27 boundary. Hardened the dispatch site in `plugins/reporting/graphs.py` to raise `CallError(ENOENT)` for any unknown name — mirroring what `netdata_graph` already does — so future schema/implementation drift surfaces as a clean RPC error rather than an unhandled exception.
axgbe: gracefully handle i2c bus failures
In (unknown) situations it seems the i2c bus can have trouble,
while nothing about the current link state has changed, the driver
would react by going into a link down state, and start busylooping
on up to 4 cores. Even if there was a valid link, such spinning
on a cpu by a kernel thread would wreak havoc to existing and
new connections.
This patch does the following:
1. If such a bus failure occurs, we keep the last known link state.
2. Prevent busy looping by implementing the lockmgr() facility to
be able to sleep while the i2c code waits on the i2c ISR. We cap
this with a timeout.
3. Pin the admin queues to the last CPU in the system, to prevent
other scenarios where busy looping might occur from landing on CPU
0, which especially seems to cause a lot of issues.
Given the design constraints both in hardware and in software,

pf|ipfw|netinet6?: shared IP forwarding
This removes the if_output calls in the pf(4) code that escape further
processing by defering the forwarding execution to the network stack
using on/off style sysctls for both IPv4 and IPv6.

axgbe: XXX leftovers to figure out
axgbe: several patches from 22.1 not yet present in FreeBSD
axgbe: remove old annotations and a bit of whitespace cleanup
This is a stub from applying f45a2d1e5a + b9eca9d898 on top of
the upstreamed changes. The enable_rss remove is correct and
looks like an oversight in the upstreaming. About the others
I'm not sure but since we have them on file here we can discuss
and rearrange.
axgbe: LED control for A30 platform
Since the I/O expander chip does not do a reset when soft power
cycling, the driver will first turn off all LEDs when initializing,
although no specific routine seems to be called when powering down.
This means that the LEDs will stay on until the driver has booted up,
after which the driver will be in a consistent state.
databases/postgresql-postgis2: Accept pgsql 18
PostgreSQL 18 is ok, per upstream's README.postgis ("and above") (and
if it didn't work I'd be hearing about it on postgis-devel@).
In PR pkg/60316, Jim Spath reports that adding 18 and testing with
qgis was successful (and also that pgsql 14 is still ok, not related
to this commit but good to know).
[mlir][SPIR-V] Add SPIRVToLLVM direct conversions for cast, CL, GL and logical ops (#202506)
Lower the OpenCL extended instruction set math ops, GL math ops (Trunc,
Asin, Acos, Atan), logical Ordered/Unordered, and the pointer cast ops
to their LLVM dialect equivalents
[AMDGPU] Use alloc size for array stride in LowerBufferFatPointers (#202530)
Array elements are laid out at multiples of getTypeAllocSize, not
getTypeStoreSize
LLVM memory model lays out array element `i` at `i * allocSize`
(reflected in `DataLayout::getTypeAllocSize`), apply it for fat pointers
to prevent miscompile
[MLIR][NVVM] Add support for narrow-fp to bf16x2 conversions (#200157)
This change adds the following NVVM Ops to support narrow-fp to bf16x2
conversions:
- `nvvm.convert.f6x2.to.bf16x2`
- `nvvm.convert.f4x2.to.bf16x2`
- `nvvm.convert.f8x2.to.bf16x2` (updated to allow `E4M3FN` and `E5M2`
types)
Also removes unnecessary verifiers for narrow-fp to `f16x2` conversions
to instead use `TypeAttrOf` to validate the source type in the ODS
definition.
