STRUCT ISHTP_HID_DATA(9)

💖 struct ishtp_hid_data(9) 💖

okay bestie, so we're in the Kernel API Manual today and the main character is literally struct ishtp_hid_data — it's the Per instance HID data, no cap. Think of it as the little vibe-holder for each HID instance out there. 🦋

✨ SYNOPSIS ✨

here's the whole glow-up, verbatim, because we do NOT mess with the source:

struct ishtp_hid_data {
    int index;
    bool request_done;
    struct ishtp_cl_data *client_data;
    wait_queue_head_t hid_wait;
    bool raw_get_req;
    u8 *raw_buf;
    size_t raw_buf_size;
 };

🎀 Members 🎀

• index — the device index, lowkey in the order of enumeration. it's giving "roll call, line up in the order you showed up" 💅
• request_done — the Get Feature/Input report complete flag 🚩 — this one's doing the work during get/set requests coming from hid core. she's the "are we done yet" of the whole situation.
• client_data — the link to the client instance 🔗. your connection to the outside world, fr fr.
• hid_wait — the completion waitq, aka the waiting room where everybody chills until the thing is done ⏳✨
• raw_get_req — a flag indicating that a raw get request is ongoing 🔥. when she's true, things are happening.
• raw_buf — the raw request buffer that gets filled up on receiving a get report 📥. the little basket collecting the goods.
• raw_buf_size — the raw request buffer size 🌸. and bestie, it's also used to tie hid hid->driver data to the driver client instance — yeah, she does double duty, iconic 👑.
