ENUM IPC_MEM_TD_CS(9)

🦋 enum ipc_mem_td_cs(9) — Kernel API Manual 🦋

okay so bestie, welcome to the manual page for enum ipc_mem_td_cs 💖 we're in Kernel API Manual territory, and this little enum is literally the completion-status vibe check for a TD. no cap.

🌸 NAME 🌸

enum ipc_mem_td_cs — Completion status of a TD. that's the whole name, and yes, “TD” stays “TD” 👑

✨ SYNOPSIS ✨

here's the enum exactly as it is, bestie — don't let the commas with space before them jump-scare you:

enum ipc_mem_td_cs {
    IPC_MEM_TD_CS_INVALID ,
    IPC_MEM_TD_CS_PARTIAL_TRANSFER ,
    IPC_MEM_TD_CS_END_TRANSFER ,
    IPC_MEM_TD_CS_OVERFLOW ,
    IPC_MEM_TD_CS_ABORT ,
    IPC_MEM_TD_CS_ERROR

};

🎀 Constants 🎀

okay so these are the constants, and each one is giving a different status update:

• IPC_MEM_TD_CS_INVALID — Initial status — td not yet used.
• IPC_MEM_TD_CS_PARTIAL_TRANSFER — More data pending -> next TD used for this
• IPC_MEM_TD_CS_END_TRANSFER — IO transfer is complete.
• IPC_MEM_TD_CS_OVERFLOW — IO transfer is too small for the buff to write
• IPC_MEM_TD_CS_ABORT — TD marked as abort and shall be discarded by AP.
• IPC_MEM_TD_CS_ERROR — General error.
