STRUCT TI_SCI_MSG_RESP_VERSION(9)

💖 struct ti_sci_msg_resp_version(9) 💖

🌸 NAME 🌸

struct ti_sci_msg_resp_version — Response for a message. Also hiii bestie, welcome to the Kernel API Manual page for this struct — it’s giving kernel firmware lore and I’m obsessed. 🫶

✨ SYNOPSIS ✨

struct ti_sci_msg_resp_version {
    struct ti_sci_msg_hdr hdr;
    char firmware_description[32];
    u16 firmware_revision;
    u8 abi_major;
    u8 abi_minor;
 };

🎀 Members 🎀

• hdr — generic header. It’s the lil’ envelope every message carries, no cap. 💌
• firmware_description — a string describing the firmware. Yup, char firmware_description[32] — it’s giving “hello, my firmware is…” energy. 🌸
• firmware_revision — firmware revision. Slay. 🔥
• abi_major — major version of the ABI that firmware supports. 👑
• abi_minor — minor version of the ABI that firmware supports. 🎀

💅 Description 💅

In general, ABI version changes follow the rule that minor version increments are backward compatible. Major revision changes in ABI may not be backward compatible.

so like, minor bump? cute, backward compatible. major bump? 😭 may not be backward compatible — do not assume, bestie. This is your warning.

Response to a generic message with message type TI_SCI_MSG_VERSION. That’s the whole tea. ☕✨
