💅 resctrl_arch_mon_event_config_write(9) 💅

ok so real talk, this page lives in the Kernel API Manual, and it's about resctrl_arch_mon_event_config_write — yeah, the name is a whole mouthful, iykyk, but we're gonna get through it together bestie 🫶

---

✨ NAME ✨

resctrl_arch_mon_event_config_write — literally just writes the config for an event. that's the whole vibe check 💖

---

🌸 SYNOPSIS 🌸

void resctrl_arch_mon_event_config_write (void *config_info );

one argument, one function, no return value, we love a low-maintenance icon 👑

---

🎀 ARGUMENTS 🎀

• config_info — a struct resctrl_mon_config_info that describes the resource, the domain, and the event. it's giving "everything you need in one little bag" 👜✨

---

💜 DESCRIPTION 💜

okay so here's the tea 🍵 — this function reads the resource, the domain, and the eventid out of config_info, and then it writes the event config_info->mon_config straight into the hardware. no cap, that's the entire personality.

and the fun part: it's called via IPI to reach a CPU that's a member of the specified domain 🖥️💫 so like, it's not just doing it locally, it's reaching out to the right CPU to get it done. main character energy fr fr.
