Subject: [FFmpeg-devel] [PATCHv2 0/6] RISC-V CPU extensions
Date: Sat, 17 Sep 2022 15:45:13 +0300
Message-ID: <5602047.DvuYhMxLoT@basile.remlab.net> (raw)
Hi,
This adds configure, compile-time, run-time detection for RISC-V scalar
and vector extensions. Also a couple of scalar optimisations.
----------------------------------------------------------------
Rémi Denis-Courmont (6):
lavu/cpu: detect RISC-V base extensions
lavu/cpu: CPU flags for the RISC-V Vector extension
configure: probe RISC-V Vector extension
lavu/riscv: initial common header for assembler macros
lavc/audiodsp: add RISC-V F float vector clip
lavc/pixblockdsp: RISC-V scalar optimisations
