resctrl_arch...r_assign_set(9)

🎀 resctrl_arch_mbm_cntr_assign_set(9) 🎀

okay so bestie, welcome to the Kernel API Manual ✨ this one's a little function in the resctrl family and honestly it's giving "small but mighty" energy 💅 it flips the MBM counter assignment mode on or off, that's literally it, and it does it so well 👑

---

✨ NAME ✨

resctrl_arch_mbm_cntr_assign_set — configure the MBM counter assignment mode 🧚

---

🌸 SYNOPSIS 🌸

int resctrl_arch_mbm_cntr_assign_set (struct rdt_resource *r , bool enable );

---

💖 ARGUMENTS 💖

• r — pointer to the resource structure 🫶 like, that's the resource you're working with, no cap
• enable — set to true to enable, false to disable the assignment mode 🔥 yes it's literally just a bool, bestie, it's a light switch and it slays

---

⭐ RETURN ⭐

0 on success, < 0 on error 😭 (so if you get anything negative back, that's your vibe check failing — handle it)
