lpfc_fcp_io_cmd_wqe_cmpl(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… lpfc_fcp_io_cmd_wqe_cmpl(9) β€” complete a FCP IO, bestie

okay so this is a page from the Kernel API Manual (yes the actual manual name, we're fancy) and it's all about the function lpfc_fcp_io_cmd_wqe_cmpl. it lives in the kernel, it's doing SCSI things, and honestly it's giving "quietly holding the whole storage stack together" energy. let's get into it πŸŽ€


🌸 NAME 🌸

lpfc_fcp_io_cmd_wqe_cmpl β€” Complete a FCP IO. that's it, that's the whole name. short, sweet, iconic. πŸ’–


✨ SYNOPSIS ✨

void lpfc_fcp_io_cmd_wqe_cmpl (struct lpfc_hba *phba , struct lpfc_iocbq
*pwqeIn , struct lpfc_iocbq *pwqeOut );

so it returns void (no return value, it just does the thing and dips, main character behavior honestly), and it takes three pointers. pointer girlies rise 🫢


πŸ¦‹ ARGUMENTS πŸ¦‹

  • phba β€” the hba for which this call is being executed. like, the host bus adapter that's out here living its life and running this call. that's the one πŸ’…
  • pwqeIn β€” the command WQE for the scsi cmnd. the incoming one. the "what are we even doing here" WQE. πŸ“₯
  • pwqeOut β€” pointer to driver response WQE object. the reply. the "here's what actually went down" WQE. πŸ“€

🧚 DESCRIPTION 🧚

bestie, listen. this routine assigns the scsi command result by looking into the response WQE status field β€” appropriately, might i add, no cap. it's literally reading the status field and setting the result accordingly, that's the whole vibe. πŸ”₯

and it doesn't stop there! this routine also handles the QUEUE FULL condition, and the way it does that is by ramping down the device queue depth. so when the queue is like "girl i literally cannot", this function is the one that's like "okay okay, slowing it down". iconic. periodt. πŸ‘‘


πŸ’œ SEE ALSO πŸ’œ

okay this is the part where the manpage just absolutely goes off β€” the see-also list is long and it's all in the kernel file ./drivers/scsi/lpfc/lpfc_scsi.c. grab a snack, we're doing all of them, no skipping:

sixty-eight references. SIXTY-EIGHT. she ate and left absolutely no crumbs. πŸ‘‘βœ¨


lowkey reminder bestie: this is kernel API documentation, so keep the exact signatures and names β€” the vibes are flexible, the facts are not πŸ’–

πŸŽ€ cute little sign-off πŸŽ€
