refill_rspq(9)

okay bestie, welcome to refill_rspq(9) from the Kernel API Manual — the little queue-refill moment that’s about to get the full group-chat treatment. 💅✨

💖 NAME 💖

refill_rspq — replenish an SGE response queue. no cap, that’s the whole name. 🫶

✨ SYNOPSIS ✨

void refill_rspq (struct adapter *adapter , const struct sge_rspq *q ,
       unsigned int credits );

🎀 ARGUMENTS 🎀

• adapter — the adapter. the whole main-character object. 👑
• q — the response queue to replenish, aka the queue getting the glow-up. 💅
• credits — how many new responses to make available. the supply drop, fr fr. 🍓

🌸 DESCRIPTION 🌸

okay so refill_rspq replenishes a response queue by making the supplied number of responses available to HW. that’s literally it: you bring the credits, and that many new responses are made available to hardware. slay, queue refilled. 💖
