Chris Sidebottom 37fc3bbca0 Add Infrastructure for SHGEMV 
This adds all the relevant bits and pieces to add a `shgemv` path as
well as a future `hgemm`/`hgemv` path in a similar model to `sb` and `b`
interfaces.

I've also fixed a few bits and pieces around `shgemm` which didn't build
in a few situations.

Chris Sidebottom 578e7dae85 Fix bf16->f32 conversion for NEOVERSEV1 and NEOVERSEN2 targets 
This fixes an issue originally introduced with the BGEMM kernel.

I've updated the tests to run with `beta=1.0` so as to test loading and
updating from C.

Alongside this, the tests now return sensible return values to reduce
the risk of them being ignored.

Also fixed a bug in `generic/gemv_t.c` resulting in weird outputs for
`bgemv`.

Fix building of bgemm tests on GEMM3M-capable (x86) targets 2025-07-28 22:43:28 +02:00
Chris Sidebottom ea2faf0c9a Add optimized BGEMM for NEOVERSEN2 target 
This re-uses the existing NEOVERSEN2 8x4 `sbgemm` kernel to implement `bgemm`.

Chris Sidebottom 2c3cdaf74e Optimized BGEMV for NEOVERSEV1 target 
- Adds bgemv T based off of sbgemv T kernel
- Adds bgemv N which is slightly alterated to not use Y as an
accumulator due to the output being bf16 which results in loss of
precision
- Enables BGEMM_GEMV_FORWARD to proxy BGEMM to BGEMV with new kernels

Chris Sidebottom e105411460 Add infrastructure for bgemv/bscal 
- Sets up all the various entrypoints for `bgemv`
- Adds `bscal` for use in the `bgemv` interface
- Adds test cases for comparing `sgemv` and `bgemv`
- Adds generic kernels for `bgemv_n` and `bgemv_t` which are accurate
enough to pass above tests

Chris Sidebottom 09a016fdf6 Split sbgemv test from sbgemm test 2025-07-13 13:39:44 +00:00
Chris Sidebottom 3f110c8272 Improve bgemm and sbgemm testing 
- Fixes wrong return type for `is_close`
- Adds stricter compiler flags for test files so we don't see the above
issue again
- Re-uses test helper functions between compare_sgemm_sbgemm/bgemm.c

Fix return type declaration 2025-07-11 15:32:41 +02:00
Chris Sidebottom 740efd71c4 Add optimized BGEMM kernel for NEOVERSEV1 target 
This also improves the testing and generic kernel by re-using the BF16
conversion functions.

Chris Sidebottom f95e7b0e32 Add infrastructure for BGEMM 
Setting up all the infrastructure for BGEMM support in OpenBLAS, hopefully I found all the right places.

Aiden Grossman b209915121 Fix build with clang 
There are two instances when building the tests where OpenBLAS fails to
build with OpenMP and clang due to library paths getting reset as flags
are set rather than appended. This seems to only affect certain
clang/libomp installations, but if it's already grabbing the correct
library paths we might as well use them.
