STRUCT NVKM_FALCON_QMGR_SEQ(9)

💖 struct nvkm_falcon_qmgr_seq(9) 💖

okay so bestie, this is a page from the Kernel API Manual and it's literally about keeping track of ongoing commands — like a little group chat read-receipt system but for GPU falcon messages 🦋

✨ NAME ✨

struct nvkm_falcon_qmgr_seq — keep track of ongoing commands 👑

---

🌸 SYNOPSIS 🌸

struct nvkm_falcon_qmgr_seq {
    u16 id;
    enum {
      SEQ_STATE_FREE = 0,
      SEQ_STATE_PENDING,
      SEQ_STATE_USED,
    SEQ_STATE_CANCELLED } state;
    bool async;
    nvkm_falcon_qmgr_callback callback;
    void *priv;
    struct completion done;
    int result;
 };

no cap, that's the whole struct, character for character, I would never do you dirty like that 🫶

🎀 Members 🎀

• id — the sequence ID, it's giving ✨name tag✨ so everyone knows which command this is
• state — the current state, aka the vibe check — it's one of SEQ_STATE_FREE = 0, SEQ_STATE_PENDING, SEQ_STATE_USED, or SEQ_STATE_CANCELLED
• callback — the callback to call upon receiving a matching message, like "hey bestie I got your text" 🔥

---

💅 Description 💅

so the way this works is: every single time a command gets sent, a sequence is assigned to it. that's literally the whole point — so the corresponding message can be matched back to it. iykyk 💀

and then, upon receiving that message, a callback can be called and/or a completion signaled. iconic behavior fr fr 🌈

⭐ lowkey a reminder to actually go read that header file, bestie, it's right there in the kernel tree 🙈
