General

  • SRU reviews and releases
  • Some misc NEW package reviews
  • Candidate interviews and take home test grading
  • 360 finalization
  • Lots of FDE-related work (mostly spec-work)
  • .NET discussions
  • Sponsored u-boot-nezha changes for Alex for the enablement of LicheeRV
  • Jira backlog work, discussions about bug handling processes
  • Sync with the Taipei HWE team
  • Some prep work for the Ubuntu Summit

Release

  • FFe reviews, some still needing additional information
  • Investigating jammy daily image build issues
    • Caused by the recently accepted fwupd SRU in jammy-proposed
    • germinate runs against the packages in the release pocket, so pulls in libfwupdplugin5, which conflicts with libfwupdplugin7
    • Steve backed out this SRU to unblock dailies
    • Needs more investigation as we already had an ABI bump fir libfwupdplugin in focal and it was fine - but maybe the dependencies on fwupd weren’t as strict or something?
  • Updated release templates to include additional release milestones
  • Refreshed ubuntu-unity-meta for the Ubuntu Unity flavor, merged+released live task workarounds in livecd-rootfs
  • Started looking into some ubuntu-advantage-tools-related concerns regarding namespacing of the new binary aliases
  • Started writing 22.04.1 retrospective document, documenting exactly what happened and our plans for improvement - and hopefully having a discussion about it at some point later

ubuntu-image

  • Few reviews of William’s Miscellaneous cleanup PR - now looking good, but we’re still in the middle of discussion!
    • Was forced to revisit some of the old live-build code for this, reminded myself of why it’s so good that we’re making ubuntu-image for classic better!
  • Reviewed William’s gadget rootfs file-path handling PR - need information
  • Investigated old card about improvements to the dynamic state machine logic - decided that the current logic and implementation doesn’t really need improvements
  • Created card for builder-extension developer documentation
  • Updated comment/description of calculateStates()

ubuntu-meta
For riscv64 we currently only have desktop images. The ubuntu-desktop package is needed for riscv64 to easily upgrade to a desktop experience on the Unmatched board.
A feature freeze exception needs to be approved for LP #1989733

systemd
systemd-boot is used for Ubuntu Core gadgets. Upstream code supports it on riscv64 but we previously did not build it.
A feature freeze exception needs to be approved for LP #1989457

Upcoming RISC-V board

  • Evaluate boot flow on board
  • Evaluate deficiencies in OpenSBI, U-Boot, kernel
  • Discuss upstreaming with vendor

U-Boot
Retest published package on different boards.
