ixgbe_clean_rx_irq(9)
β¨ NAME β¨
ixgbe_clean_rx_irq β bestie, this is the one that cleans the completed descriptors off the Rx ring, bounce-buffer style π
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. π
πΈ SYNOPSIS πΈ
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. π¦
π ARGUMENTS π
q_vectorβ the struct that's holding all the interrupt + ring info. It's giving "I know everything about what just happened" energy. πrx_ringβ the rx descriptor ring where the packets actually get transacted. This is the main character of the operation, fr. πbudgetβ the total limit on how many packets we're allowed to process. Like a snack budget but for packets. Don't exceed it, bestie. π
π DESCRIPTION π
Okay so here's the vibe: this function runs a "bounce buffer" approach to Rx interrupt processing. π§
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. β¨
Returns the amount of work completed. That's it, that's the whole deal. π
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. π

The friend group is huge, prepare yourself. π
