Subject: [PATCH v3 0/3] riscv: Add bfloat16 instruction support
Date: Fri,  6 Dec 2024 13:58:26 +0800	[thread overview]
Message-ID: <20241206055829.1059293-1-inochiama@gmail.com> (raw)

Add description for the BFloat16 precision Floating-Point ISA extension,
(Zfbfmin, Zvfbfmin, Zvfbfwma). which was ratified in commit 4dc23d62
("Added Chapter title to BF16") of the riscv-isa-manual.

Changed from v2:
1. rebase for v6.13-rc1

Changed from v1:
1. add missing code in sys_hwprobe.c

  dt-bindings: riscv: add bfloat16 ISA extension description
  riscv: add ISA extension parsing for bfloat16 ISA extension
  riscv: hwprobe: export bfloat16 ISA extension
