capDL Version 0.5.0 Release

Announcing the release of 0.5.0 with the following changes:

0.5.0 2026-03-31

Using seL4 version 15.0.0

Changes

• Add support for domain schedules in capDL-tool, capdl-loader-app, and python-capdl-tool. Domain schedules can optionally be provided in a separate section of capDL specifications. By default, the provided schedule will be started after the initialiser finishes. Provide no_start to suppress domain schedule start.

  If the kernel is not configured for domain scheduling, any provided schedule will be ignored.

Upgrade Notes

No changes are necessary for kernel configurations that do not use the domain scheduler. For kernel configurations with domain scheduler support, instead of providing the schedule in a separate .c file, the domain schedule should be provided in the capDL specification instead. Schedules can be transcribed one to one without change, leaving domain_set_start and shift_index at defaults. The difference in intended behaviour is that the schedule will only start running after the initialiser is finished. Schedules may previously have included timing for initialisation — consider if the schedule should be adjusted accordingly.
