qed_vf_pf_rxq_start(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– qed_vf_pf_rxq_start(9) β€” kernel API manual, but make it make sense πŸ’–

okay so bestie, we're in the qed_vf_pf_rxq_start(9) man page today, and honestly? it's giving "short but important." this is a kernel API function, and it does exactly one iconic thing: it starts the RX Queue by sending a message to the PF. that's it. that's the whole vibe. πŸ‘‘


✨ NAME ✨

qed_vf_pf_rxq_start β€” start the RX Queue by sending a message to the PF. no cap, that's literally the job. πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

int qed_vf_pf_rxq_start (struct qed_hwfn *p_hwfn , struct qed_queue_cid
*p_cid , u16 bd_max_bytes , dma_addr_t bd_chain_phys_addr , dma_addr_t
cqe_pbl_addr , u16 cqe_pbl_size , void __iomem **pp_prod );

look at all those arguments, she's highkey stacked. don't worry though, we're gonna go through every single one of them like the responsible bestie we are πŸ’…


🌸 ARGUMENTS 🌸

  • p_hwfn β€” HW device data. this is the hardware context, it's the main character of the whole thing ✨
  • p_cid β€” only relative fields are relevant. lowkey picky of her, but okay, we respect it.
  • bd_max_bytes β€” maximum number of bytes per bd. so like, the byte cap for each bd. πŸ“
  • bd_chain_phys_addr β€” physical address of bd chain. the actual physical address, not a vibe-address, a real one.
  • cqe_pbl_addr β€” physical address of pbl.
  • cqe_pbl_size β€” pbl size. yeah, it's just the size of the pbl. we love a self-explanatory queen 🫢
  • pp_prod β€” pointer to the producer to be used in fastpath. fastpath!!! she's fast, she's path, she's producer-adjacent πŸƒβ€β™€οΈπŸ’¨

⭐ RETURN ⭐

Int. β€” that's the return type bestie. it's an int. we move. πŸ”₯

fair warning bestie: this page is short, but it's a kernel page β€” so if you're calling it, pass those arguments exactly as documented. no improvising, no guessing, we don't do that here πŸ™ˆ

that's the whole page, and honestly? she ate. ✨ the source is ./drivers/net/ethernet/qlogic/qed, the date on this one is October 2026, and the manual tag is qed_vf_pf_rxq_start(9). go forth and start that RX queue, bestie β€” you got this πŸ’…πŸ’–
