Full Changelog: v0.9.0...v0.10.0

v0.9.0

Major changes:

• RDT
  • The resctrl filesystem is used as the "database" of classes (CTRL groups) and monitoring groups, instead of an internal cache that was previously used. The available classes are now always read directly from the resctrl filesystem which removes the potential mismatch of between what goresctrl "thinks" and what is actually available. This makes goresctrl aware of changes made outside the goresctrl API, for example.
  • The DiscoverClasses() function was dropped and replaced with SetResctrlGroupPrefix() that alters the prefix used for resctrl group (directory) names.
• Migrate to slog based logging. The internal log wrapper was dropped and the SetLogger() functions now take slog.Logger as the argument.
• Improvements in the help/usage of the sample command line applications.
• Improvements in the rdt sample application, most notably a new monitor sub-command for testing RDT metrics.
