lpfc_mbox_put(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– lpfc_mbox_put β€” from the Kernel API Manual ✨

okay bestie, so this one lives in the Kernel API Manual, and it's lowkey just the bouncer at the club door for mailbox commands. let's get into it πŸ’…


🌸 NAME 🌸

lpfc_mbox_put β€” put a mailbox cmd into the tail of the driver's mailbox queue πŸŽ€


⭐ SYNOPSIS ⭐

void lpfc_mbox_put (struct lpfc_hba * phba , LPFC_MBOXQ_t * mbq );

that's it. two args, no return value, in and out, periodt. 🫢


πŸ¦‹ ARGUMENTS πŸ¦‹

  • phba β€” pointer to the lpfc hba data structure. it's giving "the whole adapter's main character" energy ✨
  • mbq β€” pointer to the driver internal queue element for the mailbox command. this is the little ticket that's about to get in line πŸ™ˆ

πŸ’œ DESCRIPTION πŸ’œ

so the driver maintains an internal mailbox command queue, and it's implemented as a linked list β€” very demure, very linked-list. πŸ”—

when a mailbox command is issued, it shall be put into the mailbox command queue, so everything gets processed orderly. why? because the HBA can only process one mailbox command at a time. one. at. a. time. no cutting the line, no cap πŸ’€

so this function's whole vibe is: new command issued β†’ slide it onto the tail of the queue β†’ wait your turn like everyone else. that's the tea β˜•βœ¨


🌈 SEE ALSO 🌈

kernel file ./drivers/scsi/lpfc/lpfc_mbox.c β€” and honestly the whole friend group, here we go:

go read them all, i'll wait πŸ“πŸ§š


ngl there's nothing dangerous in here β€” it's just a queue append. but pls respect the ordering, the HBA genuinely cannot multitask 😭
