Subject: FlexSC influence on io_uring

Message-ID: <[email protected]> (raw)


Hi,

To what extent, if any, was the FlexSC paper an influence on io_uring?

FlexSC is described in a paper from 2010:
https://www.usenix.org/legacy/events/osdi10/tech/full_papers/Soares.pdf

FlexSC is a system for asynchronous system calls aimed at achieving
high-performance by avoiding the cost of system calls, in particular the
locality costs of executing kernel code and user code on the same core.

Implementation-wise, it seems broadly similar to io_uring, in that
system calls are submitted by writing to some location in memory, which
is later picked up by a syscall-execution thread (ala
IORING_SETUP_SQPOLL) which executes it and writes back the result.

I'm just curious if there was any influence from FlexSC on io_uring.

Thanks,
Spencer Baugh
