Intrepid Kernel UDS Planning

These are the kernel track titles and a rough outline of the topics that I think need to be covered during each track.

16:15 Intrepid Kernel Features and Flavours

• Kernel for Interpid
• version
• Custom-Binary flavours
  • Should we keep them?
• ABI check for custom-binary flavours
• splitconfig for custom-binary
• incorporate custom binaries into updateconfigs check (a frequent cause of FTBS)
• ia64 and hppa fate
• lpia might become a regular flavour instead of custom-binary
  • One of the issues discussed at the Feb/08 Lexington Sprint with lpia developers was that since lpia maintains out-of-tree patches, they are not always prepared for a kernel upload. However, lpia image creation is based on the latest kernel in the lpia archive (not always the right choice). It is possible for the uploaded kernel to be based on older lpia code then is in the lpia PPA archive because it is still undergoing development. It may make sense to decouple the lpia build cycle from the distro kernels.
  • Consider a 'debug' flavour for i386/amd64, possibly use the kernel PPA to generate the debug flavour.
    • Disable debug mechanisms in main flavours, enable in debug flavour
    • Check into using current debug image
    • default enable latencytop in the debug flavour

• ["X/KernelWishlist"]

2008-05-22

15:00 Kernel Process Issues

• Process issues

• Devise a way to notify ISV a bit in advance of kernel ABI changes(or whomever whould like to). See https://wiki.ubuntu.com/Ubiquity/DriverUpdates which started this discussion in MountainView.

  • Evaluate bug handling

15:15 LRM Reorganization

* Restructure LRM similar to LUM/LBM. * Put LRM under version control.

15:00 WLAN mesh networking support

Left over topics that need to get wedged in somewhere during UDS.

• Driver work
  • Make broken-bios kernel messages more visible to user (without being annoying)
  • ath5k help
  • fritz/fritz64/ltmodem: Look into free alternatives, check for new versions, evaluate if they even need to be in lrm anymore
  • Breaking out nvidia/fglrx into separate packages, compatible with EnvyNG
  • Cleanup lum drivers
  • Look at how other distros are handling alsa outside the kernel tree
  • Look into dkms for out-of-tree kernel modules (lum/lbm/lrm)
  • Tainting for non-ubuntu modules
  • Fix LIRC build warnings
  • incorporate loopback patches to support Wubi dirty buffer writebacks

  • http://wireless.kernel.org/en/users/Download for Gutsy/Hardy LBM

• Bookkeeping (packaging details)
  • Create a debian/rules target that sets up an external build directory for mucking with configs so as to not taint sources.
  • Miscellaneous
  • Look into boot time speedups
  • Look into kerneloops.org usage (sync from Debian)
  • Look at new scheduler configs - CONFIG_CGROUP_SCHED, CONFIG_SCHED_HRTICK, CONFIG_SCHED_DEBUG, et al.
