mips_cpc_lock_other(9)

💅 NAME 💅

Hey bestie, welcome to the mips_cpc_lock_other(9) page from the Kernel API Manual 💖.

mips_cpc_lock_other — lock access to another core. The original line is also out here saying core: the other core to be accessed, so yes, that's the target-core situation 💅✨.

---

✨ SYNOPSIS ✨

void mips_cpc_lock_other (unsigned int core );

That's the whole signature, no cap 🫶.

---

🎀 ARGUMENTS 🎀

• core — the manpage literally just says -- undescribed -- 😭 so we have zero extra deets here. No inventing, periodt. The NAME-line hint is still there though: core: the other core to be accessed.

---

🦋 DESCRIPTION 🦋

Okay so, call this before operating upon a core via the 'other' register region, so the region doesn't get moved during access 🔥.

It must be called within the bounds of a mips_cm_{lock,unlock}_other pair, and it must be followed by a call to mips_cpc_unlock_other ✨. That's the whole choreography — do not skip steps, bestie 💀.
