Miroir #[repr(C)] de struct perf_event_attr (136 octets, ver. 6.12).

Champs aux noms kernel ; Default (tout à zéro) est un attribut valide. Le champ flags agrège les bitfields kernel (disabled, inherit, exclude_kernel…) — voir les constantes associées. Un builder ergonomique relève de la couche 1.
