💅 lpfc_debugfs_dumpHBASlim_data — a Kernel API Manual moment ✨

okay so bestie, buckle up — this is a page from the Kernel API Manual (the manpage header situation is literally that), and we're talking about lpfc_debugfs_dumpHBASlim_data(9). yes it's a mouthful. no we're not renaming it. periodt.

🌸 NAME 🌸

lpfc_debugfs_dumpHBASlim_data — Dump HBA SLIM info to a buffer 🫶

like… it takes your HBA SLIM and it dumps it into a buffer. that's the whole vibe. iconic honestly.

✨ SYNOPSIS ✨

int lpfc_debugfs_dumpHBASlim_data (struct lpfc_hba *phba , char *buf ,
int size );

that's the function signature, copy it exactly, don't @ me 💅

🎀 ARGUMENTS 🎀

  • phba — The HBA to gather SLIM info from. this is your main character — the HBA in question. no phba, no SLIM, no slay.
  • buf — The buffer to dump log into. this is where the info goes to live. it's giving "empty cup, ready to be filled" 🥤
  • size — The maximum amount of data to process. the limit. the boundary. the no more than this, bestie of it all.

🦋 DESCRIPTION 🦋

This routine dumps the current contents of HBA SLIM for the HBA associated with phba to buf up to size bytes of data. And listen — this is the raw HBA SLIM data. not processed, not seasoned, not filtered. raw. 🍓

so like, you hand it an HBA (phba), you hand it a buffer (buf), you cap it with size, and it gives you the current SLIM contents straight up. no cap.

💀 NOTES 💀

okay important caveat time, bestie, pay attention:

This routine will only dump up to 1024 bytes of data each time called and should be called multiple times to dump the entire HBA SLIM. 😭 so one call will not get you the whole thing — 1024 bytes is the per-call limit, so you gotta call it again and again to get the full picture. it's giving "loading screen, but make it a loop".

Return Value: This routine returns the amount of bytes that were dumped into buf and will not exceed size. so yes, it tells you how much it actually dumped, and it will never go over your size. respectful king 👑

🔥 SEE ALSO 🔥

the friend group, the whole group chat, the extended squad — here's everyone:

Kernel file ./drivers/scsi/lpfc/lpfc_debugfs.c

and that's the whole page, bestie!! 🧚💜 this lil beauty lives over in ./drivers/scsi/lpfc, dated October 2026, and it answers to the name lpfc_debugf...HBASlim_data(9). go forth and dump that SLIM data (1024 bytes at a time, obviously). slay ✨👑
