ixgbe_cache_ring_register(9)

💖 ixgbe_cache_ring_register(9) 💖

okay so this is a section 9 kernel API page, bestie — ixgbe_cache_ring_register — and it's literally the lil' function that does "descriptor ring to register mapping" ✨ that's the whole NAME vibe, no cap.

---

🌸 SYNOPSIS 🌸

void ixgbe_cache_ring_register (struct ixgbe_adapter *adapter );

that's it. that's the whole call. void return, one argument, she's lowkey minimalist 💅

---

🎀 ARGUMENTS 🎀

• adapter — the board private struct ixgbe_adapter we're initializing. like, this is the driver's own personal stash of board-specific info, and we're handing it over so the function can fill in its ring/register situation 🫶

---

✨ DESCRIPTION ✨

so the whole plot: once we already know which feature-set is enabled for the device, we cache the register offset that the descriptor ring got assigned to. that's the job. cache the offset, move on, slay 💅

🧚 important note, fr fr: the order of the various feature calls matters! it has to start with the "most" features enabled at the same time, and then trickle down to the least amount of features turned on at once. so like, don't shuffle 'em, okay? the order is the whole point 👑
