Subject: per-cpu thoughts
Date: Wed, 20 Feb 2019 20:57:02 +0100 [thread overview]
Message-ID: <CAJ+HfNgwAFevO6cXMU_FjQtLJ=uxHmmWM8c-VWu58SMkKXgVyQ@mail.gmail.com> (raw)
Hi,
Christopher mentioned "per-cpu atomicity" in his Plumbers RISC-V HPC
talk [1]. Typically, this would be for the per-cpu implementation in
Linux, so I had a look at the current implementation.
I noticed that RISC-V currently uses the generic one. Has there been
any work on moving to a RISC-V specific impl, based on the
A-extensions, similar to what aarch64 does? Would that make sense?
Finally; Has there been any more discussions on Christopher's input?
Thanks,
Björn
