STRUCT TI_SCI_PROC_OPS(9)

🌸 struct ti_sci_proc_ops(9) — Processor Control operations 🌸

okay bestie, welcome to the Kernel API Manual ✨ this one's all about the Processor Control operations struct — think of it as the little squad of function pointers that lets you boss a physical processor around 💅

---

✨ SYNOPSIS ✨

struct ti_sci_proc_ops {
    int (*request)(const struct ti_sci_handle *handle, u8 pid);
    int (*release)(const struct ti_sci_handle *handle, u8 pid);
    int (*handover)(const struct ti_sci_handle *handle, u8 pid, u8 hid);
    int (*set_config)(const struct ti_sci_handle *handle, u8 pid, u64 boot_vector, u32 cfg_set, u32 cfg_clr);
    int (*set_control)(const struct ti_sci_handle *handle, u8 pid, u32 ctrl_set, u32 ctrl_clr);
    int (*get_status)(const struct ti_sci_handle *handle, u8 pid, u64 *boot_vector, u32 *cfg_flags, u32 *ctrl_flags, u32 *status_flags);
};

it's giving "six little function pointers, one big vibe check" 🫶 every single one of them takes a const struct ti_sci_handle *handle and a u8 pid, no cap 👑

💅 Members 💅

• request — ask to take control of a physical processor. lowkey important: the requesting host should be in the processor access list — no sneaking in, bestie 🙈
• release — give up control of a physical processor. bye-bye, handing back the keys 🎀
• handover — pass a physical processor's control over to another host in the permitted list. sharing is caring, but only if they're on the list ✨
• set_config — set the base configuration of a processor. the whole foundation, the main character energy of processor setup 👑
• set_control — set up limited control flags in specific cases. read that again — limited, specific cases, iykyk 💀
• get_status — get the state of a physical processor. the vibe check of the whole struct, fr fr 🔥

📌 NOTE 📌

the following parameters are generic in nature for all these ops — like, every single one of them hits the same little crew 🧚

-handle:     Pointer to TI SCI handle as retrieved by *ti_sci_get_handle
-pid:        Processor ID
-hid:        Host ID

so yeah — -handle, -pid, -hid, that's the trio bestie 💜 (and yeah, -handle comes from *ti_sci_get_handle, don't lose it 🌸)
