✨ knav_queue_push(9) ✨

okay so first things first, bestie: this page lives in the Kernel API Manual, and we're talking about knav_queue_push 💅 it's the little function that shoves your data to the back of the line. literally the queue's tail-end glow-up 🎀

---

🌸 NAME 🌸

knav_queue_push — push data (or descriptor) to the tail of a queue 🦋

like. it takes your stuff and puts it at the END of the queue. no cutting in line, no main character energy, just vibes at the back 🫶

---

🧚 SYNOPSIS 🧚

int knav_queue_push (void *qhandle , dma_addr_t dma , unsigned size ,
       unsigned flags );

four things in, one int out. that's the whole fit ✨

---

💖 ARGUMENTS 💖

• qhandle — the hardware queue handle 👑 this is your golden ticket, the little reference that says "yeah, I know this queue." hold onto it.
• dma — the DMA data to push 🚀 that's the actual payload getting yeeted to the tail.
• size — size of data to push 📏 gotta tell it how much, bestie. no mystery meat sizes.
• flags — can be used to pass additional information 🏷️ extra little notes, iykyk. it's the "and also…" of the argument list.

---

⭐ RETURN ⭐

0 on success, errno otherwise 😭 so like, zero is the slay outcome. anything else means something went sideways and you get an errno telling you about it. check it. fr fr.

not me writing a whole section just to say "check your return value" 💀 but genuinely, do it.
