tools/rtla: Add common_parse_options()

2026-01-07T14:57:16Z

Each rtla tool duplicates parsing of many common options. This creates maintenance overhead and risks inconsistencies when updating these options. Add common_parse_options() to centralize parsing of options used across all tools. Common options to be migrated in future patches.

tools/rtla: Add common_usage()

2026-01-07T14:57:15Z

The rtla tools have significant code quadruplication in their usage functions. Each tool implements its own version of the same help text formatting and option descriptions, leading to maintenance overhead and inconsistencies. Documentation/tools/rtla/common_options.rst lists 14 common options. Add common_usage() infrastructure to consolidate help formatting. Subsequent patches will extend this to handle other common options. The refactored output is almost identical to the original, with the following changes: - add square brackets to specify optionality: `usage: [rtla] ...` - remove `-q` from timerlat hist because hist tools don't support it - minor spacing Signed-off-by: Costa Shulyupin Link: https://lore.kernel.org/r/20251124063204.845425-1-costa.shul@redhat.com Signed-off-by: Tomas Glozar
