• HackAthonTopics

HackAthon on the 23C3, 27th - 30th December, Berlin.

This is a coordination page of the participating developers. Do not add topics unless you are prepared to join us and actually do the work.

Tasks we will work on

• 1:1 Threading LwpUserland

• import sound infrastructure changes
• use new installer

Possible tasks

All this seems very much like the ProjectsPage. This needs to be merged.

infrastructure:

• bring in PCI bridging code from FreeBSD
• Linuxulator update
• Xen Support
• Sync our PCI code as much as possible with FreeBSD's to take advantage of power saving stuff.
• Import NetBSD's kauth implementation.
• amd64 support
• fix gcc4.1
• fix APIC_IO on SMP
• import FreeBSD's cpufreq and powerd
• import nsswitch code and maybe nssldap -- import is the wrong word. we don't do dynamic binaries in /bin, so we need to have a nssd and libc communicating.
• integrate the new (lua-based) installer

Performance:

• Automated benchmark scripts so we can track performance over time.
  • What values do we want to benchmark?

    • As much as we can. I guess that we could use http://bulk.fefe.de/scalability/ as basis and create some macro benchmarks from there.

• SYSENTER/SYSEXIT
• HPET
• anticipatory disk scheduler
• NetBSD's relcache -- NIH. We have resident(1), which is supposed to be better.
• Kernel profiling and performance optimizations

Networking:

• bring in RSTP support changes to if_bridge.c from FreeBSD

FS:

• LFS
• XFS
• tmpfs
• userland filesystem support (possibly using caps?) (puffs from NetBSD?) (FUSE from FreeBSD/Csaba Henk?)
• v9fs support, i have read somewhere that the people that did the linux implementation could agree on licensing it as BSD if needed. Not sure this still applies.
• ZFS
• squashfs
