STRUCT SCMI_MESSAGE_OPERATIONS(9)

🦋 NAME 🦋

Okay so this is the struct scmi_message_operations(9) page from the Kernel API Manual, and the NAME is literally struct scmi_message_operations — Transport core operations for Message. No cap, that's the whole vibe. 💅

✨ SYNOPSIS ✨

       struct scmi_message_operations {
           size_t (*response_size)(struct scmi_xfer *xfer);
           size_t (*command_size)(struct scmi_xfer *xfer);
           void (*tx_prepare)(struct scmi_msg_payld *msg, struct scmi_xfer
       *xfer);
           u32 (*read_header)(struct scmi_msg_payld *msg);
           void (*fetch_response)(struct scmi_msg_payld *msg, size_t len,
       struct scmi_xfer *xfer);
           void (*fetch_notification)(struct scmi_msg_payld *msg, size_t len,
       size_t max_len, struct scmi_xfer *xfer);
        };

• response_size — get the calculated response size for xfer. Slay. 💖
• command_size — get the calculated command size for xfer. Iconic. ✨
• tx_prepare — prepare the xfer message for transmission on the provided msg. It's giving prep era. 🎀
• read_header — read the header of the message currently held in msg. Bestie, it's right there. 🦋
• fetch_response — copy the message response from msg into xfer. Main character copy-paste energy. 🌸
• fetch_notification — copy the message notification from msg into xfer. Not me being obsessed with notifications. 💅
