STRUCT MBM_CNTR_CFG(9)

💖 NAME 💖

okay so this is the page for struct mbm_cntr_cfg(9) in the Kernel API Manual, and it's literally the Assignable counter configuration. bestie — cute little struct, very resctrl, very demure 💅

✨ SYNOPSIS ✨

struct mbm_cntr_cfg {
    enum resctrl_event_id   evtid;
    struct rdtgroup         *rdtgrp;
 };

• evtid — the MBM event this counter is assigned to. Tiny but crucial caveat: it's only valid when rdtgroup is not NULL, no cap. ⭐
• rdtgrp — the resctrl group assigned to the counter. It's NULL when the counter is free, and that's the whole vibe check. 🦋
