The purpose of this work was to provide proper measurements of the performance impacts of kernel debug tooling. I found that the default installation of 16.0-CURRENT (i.e. with debug) was significantly slower than 15.0-RELEASE, particularly in areas such as memory allocation. On the other hand, 16.0-CURRENT when configured correctly had performance comparable to 15.0-RELEASE in every test I ran. A link:https://github.com/Humanoid-Human/fbsd-work/blob/main/kernel-benchmark.md[full writeup] is available. ==== MAINTAINERS Modernization Based on the info from the link:https://github.com/freebsd/srcmgr/issues/21[srcmgr thread], I made a layout for a UCL file that would store maintainers and paths to watch, as a replacement for the current MAINTAINERS file. I then wrote a flua script that reads this file and can output CODEOWNERS for GitHub or Forgejo, get the maintainers for a particular path, get paths for a particular maintainer, etc. The pull request can be found link:https://github.com/freebsd/freebsd-src/pull/2107[here]. ==== pkg to Distribution Set Converter Currently working on writing a shell script that can convert a pkgbase package set into a distribution set. This would help facilitate the transition to pkgbase. Sponsor: The FreeBSD Foundation
