STRUCT WCNSS_CTRL(9)

✨ struct wcnss_ctrl — the driver context glow-up ✨

okay bestie, so this is a page from the Kernel API Manual (yes, the kernel has lore too 💅) and it's all about struct wcnss_ctrl — literally the driver context. think of it as the main character's little bag of holding: everything the driver needs to keep track of lives in here 🎀

---

🌸 SYNOPSIS 🌸

here's the whole squad, exact and untouched, no cap:

struct wcnss_ctrl {
    struct device *dev;
    struct rpmsg_endpoint *channel;
    struct completion ack;
    struct completion cbc;
    int ack_status;
    struct work_struct probe_work;
 };

---

🦋 Members 🦋

time for a vibe check on every single field, and yes, we're doing all of them 💖

• dev — the device handle. your classic device rep, holding it down 🫶
• channel — the SMD channel handle. this is the actual line to the other side ✨
• ack — a completion for outstanding requests. it's giving "pls reply, I'm waiting" energy 😭
• cbc — a completion for the cbc complete indication. when cbc says it's done, this is how you hear about it 🔥
• ack_status — the status of the outstanding request. did it slay or did it flop, this tells you 👑
• probe_work — the worker for uploading the nv binary. the little workhorse doing the upload task, iconic behavior 🧚

heads up bestie: literally every field above is copied character for character, so don't go renaming anything or the kernel will simply not be your friend 🙈

and that's the whole page!! no crumbs left, everything's here 🌈

mk bye ily, this one lives in ./drivers/soc/qcom, straight from the October 2026 drop of the Kernel API Manual — struct wcnss_ctrl(9), periodt 💅⭐
