qman_p_poll_dqrr(9)

🌸 NAME 🌸

okay so bestie, this is qman_p_poll_dqrr(9) — it’s literally here to process DQRR (fast-path) entries. That’s the whole vibe. 💅

✨ SYNOPSIS ✨

int qman_p_poll_dqrr (struct qman_portal *p , unsigned int limit );

🫶 ARGUMENTS 🫶

• p — -- undescribed -- (yep, that’s literally what the page says; no extra lore).
• limit — the maximum number of DQRR entries to process.

💖 DESCRIPTION 💖

Use of this function requires that DQRR processing not be interrupt-driven. Like, that’s the setup, bestie — no interrupt-driven DQRR processing here.

The return value represents the number of DQRR entries processed. Its return type is int, per the synopsis. 💫

Heads up: the not-interrupt-driven requirement is a real requirement, not a vibe suggestion. 👑
