process_pure_responses(9)

💅 process_pure_responses(9) 💅

okay bestie, welcome to the Kernel API Manual page for process_pure_responses(9) — we are processing pure responses today and the vibes are immaculate ✨

---

🌸 NAME 🌸

process_pure_responses — process pure responses from a response queue 💖

---

✨ SYNOPSIS ✨

int process_pure_responses (struct adapter *adap , struct sge_qset *qs ,
       struct rsp_desc *r );

---

🎀 ARGUMENTS 🎀

• adap — the adapter. literally the adapter. 🫶
• qs — the queue set that owns the response queue. she owns it. 👑
• r — the first pure response to process. first up, bestie. ⭐

---

🦋 DESCRIPTION 🦋

okay so this is a simpler version of process_responses — a lowkey glow-up that handles only pure (i.e., non data-carrying) responses. Such responses are too light-weight to justify calling a softirq under NAPI, so we handle them specially in the interrupt handler. not me doing interrupt-handler duty 💅

The function is called with a pointer to a response, and the caller must ensure it is a valid pure response. that's the vibe check: valid pure response or don't call it, fr fr 🙈

Returns 1 if it encounters a valid data-carrying response, 0 otherwise. those are the return-value receipts 🧾✨
