Adding the raw EVENT_xxH event lists to each table ensures that you can always request the exact events you want, regardless of what has been detected or is known.

A future update to these definitions should greatly improve this support. The alias table is empty for now, until this future import is complete.

However, this field shouldn't be used to carry the actual pmc event code anyway, as it is expected to contain the index into the pmu event array (otherwise, it breaks event name lookup in pmclog_get_event()). Add a new MD field, pm_md.pm_md_config, to pass the raw event code to arm64_allocate_pmc(). Additionally, the change made to pmc_md_op_pmcallocate was incorrect, as this is a union, not a struct. Restore the proper padding size. Reviewed by: luporl, ray, andrew Fixes: 28dd6730a5d6 ("libpmc: enable pmu_utils on arm64") Fixes: 8cc3815f02be ("hwpmc_arm64: accept raw event codes...")
