1.8 Planning

1.8 Priorities

  • Developer Workflow
    • Silent failure, CONFIG_ missing/overridden/irrelevant - Fixed
  • Automation and QA Testing
    • Kernel manual guides
      • Testing the process within the Manual
      • Tooling would change and process would break
      • This will need to be pushed to 1.9
    • Yocto BSP tooling
    • wic
  • Meta-Data cleanup
    • intel-common - factor our platforms, don't just include the entire BSP scc
  • BSP Updates
  • linux-yocto-dev by M1
  • Deployment Mark Hatle owns this now
  • BSP Refactor
    • Not including whole BSPs
    • purge remaining MACHINE_ARCH packages for meta-intel
    • runtime BSP customization (aka HDMI audio on the NUC, etc.)
  • Continue Poky Tiny
    • Still needs to work
    • Need to add tiny variant for Intel Core BSP
  • Future
    • Autobuilder detection of config changes

1.8 Commitments

  • The MUT branch will be built using linux-yocto-dev on a regular basis on the Autobuilder starting at M1.
  • The versioned kernel recipe will be submitted at RC1 and before feature-freeze.
  • The core-image-kernel-dev recipe will be moved from poky-extras into oe-core and used for kernel sanity and stress testing.
  • Two weeks prior to the feature freeze date, the kernel team will send a Kernel Status Report detailing the current state of linux-yocto-dev, including the most likely kernel version (98% confidence) based on the known inputs and enumerate any unknowns. The report will include a list of known issues from the MUT builds which will reduce the surprise and scramble following the merge. The issue list is expected to be minimal given the prior runs in MUT. Factors influencing the final linux-yocto kernel version include the base kernel version for PREEMPT_RT, LTSI, stable, etc. which are beyond our control. Depending on the priorities for the release, any of these may impact the final kernel version decision. Should new or late arriving information necessitate a change to the kernel version, it will be raised with the CCB and re will need to weigh the risk (which will be much less with the MUT builds) and possible schedule slippage with the benefits (such as aligning with LTSI or PREEMPT_RT). Note that we cannot always meet all requirements of schedule and external tree support and at each release we must choose between them.
