Subject: [PATCH V3 0/5] riscv: atomic: Optimize AMO instructions usage
Date: Wed, 20 Apr 2022 22:44:12 +0800	[thread overview]
Message-ID: <20220420144417.2453958-1-guoren@kernel.org> (raw)

From: Guo Ren <guoren@linux.alibaba.com>

These patch series contain one cleanup and some optimizations for
atomic operations.

Changes in V3:
 - Fixup usage of lr.rl & sc.aq with violation of ISA
 - Add Optimize dec_if_positive functions
 - Add conditional atomic operations' optimization

Changes in V2:
 - Fixup LR/SC memory barrier semantic problems which pointed by
   Rutland
 - Combine patches into one patchset series
 - Separate AMO optimization & LRSC optimization for convenience
   patch review

Guo Ren (5):
  riscv: atomic: Cleanup unnecessary definition
  riscv: atomic: Optimize acquire and release for AMO operations
  riscv: atomic: Optimize memory barrier semantics of LRSC-pairs
  riscv: atomic: Optimize dec_if_positive functions
  riscv: atomic: Add conditional atomic operations' optimization
