Martin Pieuchot (mpi@) has
committed
a change unlocking the
mmap(2),
munmap(2),
and
mprotect(2)
system calls:

CVSROOT:	/cvs
Module name:	src
Changes by:	mpi@cvs.openbsd.org	2022/11/08 04:05:57

Modified files:
	sys/kern       : syscalls.master 

Log message:
Mark mmap(2), munmap(2) and mprotect(2) as NOLOCK.

Accesses to data structures used by these syscalls are serialized by the
VM map lock with the exception of file mappings which are still protected
by the KERNEL_LOCK().

Unlocking this set of syscalls improves most of userland workloads.

Tested by many including robert@ (since 2 years), mlarkin@, kn@, sdk@,
jca@, aoyama@, naddy@, Scott Bennett and others. Thanks to all!

Joint work with kn@.

ok robert@, aja@, kettenis@, kn@, deraadt@, beck@

The improvement in workload performance can
be quite marked.
Following Martin’s
request for testing,
Mike Larkin (mlarkin@)
reported build performance improvement of over 12%!

About the devroom

=================

  The Binary Tools Devroom at FOSDEM 2023 is an informal, technical,

  event oriented to authors, users and enthusiasts of FLOSS

  programs that deal with binary data.

  This includes binary editors, libraries to encode and decode data,

  parser generators, binary data description languages and frameworks,

  binary formats and encodings, assemblers, debuggers, reverse

  engineering suites, and the like.

  The goal of the devroom is for developers to get in touch with each

  other and with users of their tools, have interesting and hopefully

  productive discussions, and finally what is most important: to have

  fun.

Suggested Topics

================

  Here is a non-exhaustive list of binary tools about which we would

  like to have activities:

   – GNU poke

   – fq

   – radare2

   – kaitai struct

   – binwalk

   – wireshark

   Both using (like a nice hack) and developing the tools are on-topic.

   Activities on increasing collaboration between the tools are

   particularly encouraged.

Proposals

=========

   Proposals should be made through the FOSDEM Pentabarf submission tool]. You

   do not need to create a new Pentabarf account if you already have one from a

   past year.

   https://penta.fosdem.org/submission/FOSDEM23

   Please select the “Binary Tools Devroom” as the track and ensure

   you include the following information when submitting a proposal:

   – The name of the person, or persons, doing the proposed activity.

  

   – A short bio (one paragraph) for each person.

   – If desired, a photo 😎

   – The title of the activity.

   – Activity abstract.

   – Duration of the activity: 15 minutes or 30 minutes.

   The deadline for submissions is November 25th, 2022. FOSDEM will be

   held on the weekend of February 4-5, 2023 and the Binary Tools

   devroom will take place on Sunday, February 5, 2023 in Brussels,

   Belgium.
