STRUCT SCMI_XFER_RAW_WAITER(9)

💖 struct scmi_xfer_raw_waiter(9) 💖

okay bestie, we’re in the Kernel API Manual and this page is literally all about struct scmi_xfer_raw_waiter — the structure that describes an xfer you’re waiting for. no cap, that’s the whole assignment. 🎀

---

✨ NAME ✨

struct scmi_xfer_raw_waiter — structure to describe an xfer to be waited for. periodt. 💅

---

🦋 SYNOPSIS 🦋

okay so the struct itself is giving exactly this, verbatim:

struct scmi_xfer_raw_waiter {
    unsigned long start_jiffies;
    struct scmi_chan_info *cinfo;
    struct scmi_xfer *xfer;
    struct completion async_response;
    struct list_head node;
 };

---

🌸 Members 🌸

every member is iconic in its own way, so let’s go through them one by one, fr fr:

• start_jiffies — the timestamp in jiffies of when this structure was queued. ⏱️
• cinfo — a reference to the channel to use for this transaction. it’s giving “this is the lane we’re using” energy. 🛣️
• xfer — a reference to the xfer to be waited for. main character xfer, honestly. 👑
• async_response — a completion to be, optionally, used for async waits: it will be setup by scmi_do_xfer_raw_start, if needed, to be pointed at by xfer->async_done. yes bestie, that exact chain. 🔗
• node — a list node. simple, cute, does its job. 🎀
