📦 version 7.3.1, in nixpkgs unstable

💌 bfa_nw_ioc_mbox_queue(9) — like, the kernel API manual bestie, but make it cute

okay so this is a page from the Kernel API Manual, section 9, and it's all about bfa_nw_ioc_mbox_queue. yes the name is a mouthful, no we're not renaming it, she's iconic as she is 💅

✨ NAME ✨

bfa_nw_ioc_mbox_queue — literally just queues a mailbox command request to firmware. that's the whole vibe. 🎀

🦋 SYNOPSIS 🦋

bool bfa_nw_ioc_mbox_queue (struct bfa_ioc *ioc , struct bfa_mbox_cmd
*cmd , bfa_mbox_cmd_cbfn_t cbfn , void *cbarg );

she returns a bool, she takes four args, and yes you have to line them up exactly like that. no cap. ✨

🌸 ARGUMENTS 🌸

  • ioc — the IOC instance 🫶 like, the actual thing you're poking at
  • cmd — the mailbox command itself, the star of the show 👑
  • cbfn — your callback function, aka who gets pinged later 📞
  • cbarg — the arguments you're handing to that callback, little care package for later 🎁

💖 DESCRIPTION 💖

so basically: if the mailbox is busy, this thing waits. that's it, that's the behaviour — she's patient, she's not gonna barge in 🙈

and the responsibility of the caller is to serialize. yes, you, bestie. that's your job, not hers. don't make it weird. ⚠️

ngl this is the part people skim and then get confused about later. serialize your calls. periodt. 💀
