Release date: 2023-12-22

Release Management ticket: REL-944

Fixed

LOW-578

The hardware_connections table used by the LOW-CBF Allocator to map Alveos to P4 switch ports is now configurable through Helm values. This solves the issue where a manual workaround was needed to deploy ska-low-csp with the correct mapping for the environment.

Example configuration:

ska-low-csp:
  ska-low-cbf:
    cbf:
      hardware_connections:
        - "switch=p4_01  port=5/0  speed=100  alveo=XFL1IYUNES2E"
        - "switch=p4_01  port=9/0  speed=100  alveo=XFL1EG4H5YXY"
        - "switch=p4_01  port=13/0  speed=100  alveo=XFL1XXQM0FKW"
        - "switch=p4_01  port=17/0  speed=100  alveo=XFL1BB1SEWXK"
        - "switch=p4_01  port=21/0  speed=100  alveo=XFL1SZ2IUU2I"
        - "switch=p4_01  port=25/0  speed=100  alveo=XFL121Y1KXMA"
