lpfc_get_stats(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… lpfc_get_stats(9) β€” yeah she's in the Kernel API Manual, get into it

okay so bestie, gather round, because we're about to talk about lpfc_get_stats β€” the little function whose whole entire job is to hand you the statistical tea about the adapter. she's giving "backstage pass to the host's receipts" and honestly? iconic. πŸŽ€


✨ NAME ✨

lpfc_get_stats β€” Return statistical information about the adapter 🌸


🌈 SYNOPSIS 🌈

struct fc_host_statistics * lpfc_get_stats (struct Scsi_Host *shost );

no cap, that's the whole signature. one function, one struct pointer coming back at you. 🫢


πŸ¦‹ ARGUMENTS πŸ¦‹

  • shost β€” the kernel scsi host pointer. that's it, that's the whole vibe. pass her in and she knows which host she's talking about πŸ’«

πŸ’€ NOTES πŸ’€

okay so this is the part where you gotta pay attention, because she's a little dramatic and will absolutely hand you NULL in a whole bunch of situations. she returns NULL on error for:

  • link down 😭
  • no mbox pool
  • sli2 active
  • management not allowed
  • memory allocation error
  • mbox error

like miss girl has conditions. respect them. πŸ™ˆ


πŸ‘‘ RETURN πŸ‘‘

NULL for error, otherwise the address of the adapter host statistics πŸ’– β€” that's your prize, that's the data, slay.
