STRUCT QCOM_RPM_MESSAGE(9)

🎀 NAME 🎀

struct qcom_rpm_message — response message from the rpm. And yes bestie, this is straight out of the Kernel API Manual, so you know it's official.

✨ SYNOPSIS ✨

struct qcom_rpm_message {
    __le32 msg_type;
    __le32 length;
    union {
      __le32 msg_id;
      u8 message[];
    };
};

💅 Members 💅

• msg_type (__le32) — indicator of the type of message. It's giving "what kind of message is this?" energy.
• length (__le32) — the size of this message, including the message header. So yes, the header counts, no cap.
• {unnamed_union} — anonymous. Literally an unnamed union doing its anonymous little thing.
• msg_id (__le32) — message id.
• message (u8 message[]) — textual message from the rpm. The actual words, bestie.

🌸 Description 🌸

Multiple of these messages can be stacked in an rpm message. That's the whole vibe: they pile up together inside one rpm message.
