STRUCT TI_SCI_MSG_REQ_SET_CONFIG(9)

💅 NAME 💅

struct ti_sci_msg_req_set_config — Set Processor boot configuration ✨

okay bestie, welcome to the Kernel API Manual, and buckle up because this one is a whole struct about telling a processor how to boot 💖

---

✨ SYNOPSIS ✨

struct ti_sci_msg_req_set_config {
    struct ti_sci_msg_hdr hdr;
    u8 processor_id;
    u32 bootvector_low;
    u32 bootvector_high;
    u32 config_flags_set;
    u32 config_flags_clear;
};

no cap, that's the whole shape of it 🎀

---

🎀 MEMBERS 🎀

• hdr — Generic Header. literally the standard-issue header that everything in this family rolls with 🫶
• processor_id — ID of processor being configured. like, which processor are we even talking to, bestie 💅
• bootvector_low — Lower 32 bit address (Little Endian) of boot vector. the bottom half of the address, endian girlie that it is 🌸
• bootvector_high — Higher 32 bit address (Little Endian) of boot vector. and here's the top half to complete the vibe check ⭐
• config_flags_set — Optional Processor specific Config Flags to set. Setting a bit here implies the corresponding mode will be set 🔥 (yes, every bit is basically a "turn this mode on" button)
• config_flags_clear — Optional Processor specific Config Flags to clear. Setting a bit here implies the corresponding mode will be cleared 💀 (and every bit here is the "turn it off" button — yin and yang fr fr)

---

💖 DESCRIPTION 💖

Request type is TI_SCI_MSG_PROC_HANDOVER, response is a generic ACK/NACK message 🦋

so like, you send this request, and the universe (the firmware) replies with a plain little ACK or NACK. iconic, minimal, no drama 👑
