fm10k_cache_ring_qos(9)

🎀 NAME 🎀

fm10k_cache_ring_qos — descriptor ring to register mapping for QoS, bestie 💅

Okay so real talk, this little icon lives in the Kernel API Manual, and it does exactly one gorgeous little thing: it caches the descriptor ring offsets for QoS. That's the whole vibe. ✨

---

🌸 SYNOPSIS 🌸

bool fm10k_cache_ring_qos (struct fm10k_intfc *interface );

That bool return type is giving "yes or no, no in-between" energy 💀

---

🦋 ARGUMENTS 🦋

• interface — the interface structure that's out here containing all the rings and devices (the original spells it "continaining" and honestly? we respect the typo queen 🫶). This is the thing you're handing over so the ring stuff can get cached.

---

🧚 DESCRIPTION 🧚

It caches the descriptor ring offsets for QoS. That's it, that's the whole main character moment 👑

Like, the ring-to-register mapping for QoS? Yeah. It gets cached. Iconic behaviour, no notes, lowkey obsessed. 🎀

ngl there's not a lot of lore here — this page is short and it knows it. The details above are the entire story 💖
