STRUCT SCMI_MSG_RESP_PROT_VERSION(9)

🦋 struct scmi_msg_resp_prot_version — Kernel API Manual ✨

okay bestie, welcome to the Kernel API Manual entry for struct scmi_msg_resp_prot_version — yes that's a whole mouthful, i know, but stick with me because this one is actually kinda cute and smol 💅

---

🌸 NAME 🌸

struct scmi_msg_resp_prot_version — the response for a message 🫶 literally that's it, that's the whole vibe

---

✨ SYNOPSIS ✨

struct scmi_msg_resp_prot_version {
    __le16 minor_version;
    __le16 major_version;
 };

like. look at her. two little __le16 fields and a dream 🎀

---

💖 Members 💖

• minor_version — the minor version of the ABI that firmware supports ✨ the lil baby number
• major_version — the major version of the ABI that firmware supports 👑 the big boss number

---

🌈 Description 🌈

so in general, ABI version changes follow the rule that minor version increments are backward compatible 🥳 which like… slay, love that for us, no breaking changes queen.

but major revision changes in ABI may not be backward compatible 😭 so like, be aware, no cap. major bumps can absolutely ruin your whole day and that's just the truth of it.

also! this struct is the response to a generic message with message type SCMI_MSG_VERSION ⭐ iykyk

🧚 SEE ALSO 🧚

okay the whole friend group shows up here, and honestly they're all iconic:

• Kernel file ./drivers/firmware/arm_scmi/protocols.h struct scmi_msg(9)
• struct scmi_msg_hdr(9)
• struct scmi_xfer(9)
• struct scmi_protocol_handle(9)
• struct scmi_iterator_state(9)
• struct scmi_iterator_ops(9)
• struct scmi_proto_helpers_ops(9)
• struct scmi_xfer_ops(9)
• struct scmi_protocol(9)

fr fr go read those too, they're all in ./drivers/firmware/arm_scmi and they understood the assignment 💜

aaaand that's the whole page bestie 💀🦋 this lil cutie lives in ./drivers/firmware/arm_scmi, dated October 2026, in the Kernel API Manual — same title top and bottom, struct scmi...prot_version(9), no notes, periodt 🎀💖✨
