StarlingX/IA Features

StarlingX IA Feature Sub-project

This project is for work items to enable Intel Architecture specific features.

Team Information

  • Project Lead: TBD
  • Technical Lead: TBD
  • Core Reviewers: TBD
  • Contributors: TBD

Team Objective / Priorities

  • Validate that existing IA Features already supported in StarlingX are working correctly
  • Address any defects in IA Feature support
  • Add support for new IA features


All story board stories and launchpad bugs created for this team should use the tag "stx.ia"

Team Work Items

    • TBD

New IA features for StarlingX

In general we want to wait for upstream communities to implement these features e.g. the kernel, OpenStack, Kubernetes and pick them up as we adopt newer versions of upstream packages. However some features may require StarlingX specific work and all features will require Testing in StarlingX.

Feature Description Baseline Use Cases Implementation Dev Status Testing Status
Cache Allocation Technology (CAT) Ability to isolate portions of cache for improved determinism All SKUs starting with the Xeon E5 v4 family Isolating cache of critical VM from noisy neighbor to guarantee performance TBD TBD TBD
