ixgbe_handle_mdd_event(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– ixgbe_handle_mdd_event β€” handle mdd event πŸ’–

okay bestie, so this one lives in the Kernel API Manual (yup, section 9, kernel internals, we're in the big leagues now) and it's literally the function that catches a bad-vibes VF doing bad-vibes things. let's get into it ✨


🌸 NAME 🌸

ixgbe_handle_mdd_event β€” handle mdd event

like, that's the whole name, that's the whole job. mdd event handling. iconic behaviour, no notes πŸ’…


πŸ¦‹ SYNOPSIS πŸ¦‹

void ixgbe_handle_mdd_event (struct ixgbe_adapter *adapter , struct
       ixgbe_ring *tx_ring );

so it takes two pointers and hands you back nothing β€” it's a void function, she does the work and dips, no return value, no receipts 🫢


πŸŽ€ ARGUMENTS πŸŽ€

  • adapter β€” the struct ixgbe_adapter situation, aka the structure containing ring specific data. this is the main character of the whole driver bestie πŸ’œ
  • tx_ring β€” the tx_ring descriptor ring to handle. the struct ixgbe_ring * that needs the attention πŸ“

πŸ”₯ DESCRIPTION πŸ”₯

okay so real talk: this function Resets the VF driver if a malicious VF is detected, or if an illegal packet is detected in any queue. that's it, that's the whole plot 😭

like, something sus is going down β€” either a VF is acting malicious or some packet is out here being illegal in a queue it has no business being in β€” and this function responds by resetting the VF driver. no negotiation, no second chances, just reset. periodt πŸ’€

ngl, "malicious vf" and "illegal packet" are both extremely serious situations, so this function existing at all is lowkey a vibe check for your hardware πŸ‘‘

the kernel file this bad boy lives in, fr fr:

  • ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c

and now the friend group, because this function rolls deep 🫢 (every single one, we're not skipping anybody, bestie):

like… that's the whole extended universe, bestie, and every single one is linked up so you can go read them yourself. iykyk 🌈
