scmi_xfer_in...ter_unlocked(9)

🌸 scmi_xfer_in...ter_unlocked(9) 🌸

okay bestie, you're in the Kernel API Manual and the main character is scmi_xfer_in...ter_unlocked(9) — yes, the title is literally truncated like that, and we're keeping it 💅.

💖 NAME 💖

scmi_xfer_inflight_register_unlocked — Register the xfer as in-flight ✨

✨ SYNOPSIS ✨

the exact signature, no edits, no cap:

void scmi_xfer_inflight_register_unlocked (struct scmi_xfer *xfer ,
       struct scmi_xfers_info *minfo );

🎀 ARGUMENTS 🎀

• xfer — The xfer to register 🫶
• minfo — Pointer to Tx/Rx Message management info based on channel type 💫

🦋 DESCRIPTION 🦋

lowkey important note: this helper assumes that the xfer to be registered as in-flight had been built using an xfer sequence number which still corresponds to a free slot in the xfer_alloc_table.

That's the assumption it's rolling with, periodt 🌸

💅 CONTEXT 💅

Assumes to be called with xfer_lock already acquired. Periodt. So bestie, lock first — that's the rune it's living by 💜
