💅 resctrl_arch...num_rmid_idx(9) 💅

okay bestie, welcome to the resctrl_arch...num_rmid_idx(9) page from the Kernel API Manual — it's giving very specific kernel-internals realness and honestly? We love that for us. ✨

---

✨ NAME ✨

resctrl_arch_system_num_rmid_idx — computes the number of supported RMIDs, specifically the minimum across all mon_capable resource. No cap, that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

u32 resctrl_arch_system_num_rmid_idx (void );

---

🦋 ARGUMENTS 🦋

• void — literally no arguments, bestie. She takes nothing. Main character energy with zero parameters. 💅

---

⭐ RETURN ⭐

Returns the number of supported RMIDs at the time of the call. 🫶

heads up though: mount time enumeration of resources may reduce that number. So the number you get at call time is the number at call time — the mount-time resource enumeration can still lowkey bring it down. 😭

mwah 💋 this lil icon comes from ./arch/x86/kernel/cpu/resctrl, dated October 2026 — and yes, it's still the resctrl_arch...num_rmid_idx(9) manual page. periodt. 👑🌈
