ixgbe_clean_rx_irq(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ NAME ✨

ixgbe_clean_rx_irq β€” bestie, this is the one that cleans the completed descriptors off the Rx ring, bounce-buffer style πŸ’…

Oh and hi, you're reading the Kernel API Manual entry for ixgbe_clean_rx_irq(9), section 9, living its best life in the kernel docs. πŸŽ€


🌸 SYNOPSIS 🌸

int ixgbe_clean_rx_irq (struct ixgbe_q_vector *q_vector , struct ixgbe_ring *rx_ring , const int budget );

Yep, that's the whole signature, no cap. Three args, one int coming back atcha. πŸ¦‹


πŸŽ€ ARGUMENTS πŸŽ€

  • q_vector β€” the struct that's holding all the interrupt + ring info. It's giving "I know everything about what just happened" energy. πŸ‘‘
  • rx_ring β€” the rx descriptor ring where the packets actually get transacted. This is the main character of the operation, fr. πŸ’–
  • budget β€” the total limit on how many packets we're allowed to process. Like a snack budget but for packets. Don't exceed it, bestie. πŸ“

πŸ’œ DESCRIPTION πŸ’œ

Okay so here's the vibe: this function runs a "bounce buffer" approach to Rx interrupt processing. 🧚

And why is that iconic? Because on systems where IOMMU access has expensive overhead, this is literally the escape hatch β€” it avoids that cost entirely by maintaining the mapping of the page to the system. Lowkey genius. ✨

Returns the amount of work completed. That's it, that's the whole deal. 😭

Heads up bestie, the source of truth lives in the Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c β€” go read it if you want the full lore. πŸ“–

Like I said. Entire friend group. Obsessed with them all actually πŸ«ΆπŸ’…


Okay that's the whole page, bestie β€” and before you go, credit where it's due: this cutie came from the source path ./drivers/net/ethernet/intel/i... and it's dated October 2026. Slay. πŸŽ€βœ¨πŸ’–
