💅 mptbase_sas_persist_operation(9) — Kernel API Manual ✨

okay so bestie, welcome to the kernel API manual, this one's a function page and it's literally about poking the SAS Persistent Table 🎀

---

🌸 NAME 🌸

mptbase_sas_persist_operation — do a little operation on the SAS Persistent Table, that's the whole vibe 💫

---

✨ SYNOPSIS ✨

int mptbase_sas_persist_operation (MPT_ADAPTER *ioc , u8 persist_opcode );

---

🦋 ARGUMENTS 🦋

• ioc — a pointer to the MPT_ADAPTER structure, iykyk, that's your adapter right there 🫶
• persist_opcode — which operation you want. all the deets are, like, right below 👇

---

💖 DESCRIPTION 💖

so here's the lineup of opcodes, no cap:

• MPI_SAS_OP_CLEAR_NOT_PRESENT — frees all persist TargetID mappings for devices that are not currently present. bye to the ghosts 👋
• MPI_SAS_OP_CLEAR_ALL_PERSISTENT — clears all persist TargetID mappings. every last one. periodt 💀
