STRUCT RDT_PERF_PKG_MON_DOMAIN(9)

💅 struct rdt_perf_pkg_mon_domain — from the Kernel API Manual, section 9 🎀

okay bestie, welcome to the manual page for struct rdt_perf_pkg_mon_domain, straight out of the Kernel API Manual (that's section 9, iykyk) ✨ and yeah the running header got truncated to struct rdt_p...g_mon_domain(9) because even the kernel has a character limit, we love that for her 💀

---

✨ NAME ✨

struct rdt_perf_pkg_mon_domain — the CPUs that share a package-scoped resctrl monitor resource 🦋

Like, that's it, that's the whole vibe. It's the struct that says "hey, these CPUs are all sharing one resctrl monitor resource, and that resource is scoped to the package" 💖

---

🌸 SYNOPSIS 🌸

struct rdt_perf_pkg_mon_domain {
    struct rdt_domain_hdr   hdr;
 };

not me noticing the little stray space before that closing } — that's exactly how it's written in the source, so I'm keeping it fr fr, character for character, no cap 🫶

---

👑 Members 👑

• hdr — the common header for different domain types ✨ every domain type gets one of these, it's the shared little crown they all wear 💅
