lpfc_sc_to_bg_opcodes(9)

💅 lpfc_sc_to_bg_opcodes(9) — a Kernel API Manual moment

okay so bestie, welcome to the lpfc_sc_to_bg_opcodes(9) page, straight out of the Kernel API Manual ✨ this one's a little function from the lpfc crew and it's literally just here to figure out which BlockGuard opcodes go with a specific SCSI command. short king, but important 🫶

---

🌸 NAME 🌸

lpfc_sc_to_bg_opcodes — determine the BlockGuard opcodes to be used with the specified SCSI command 💅

---

✨ SYNOPSIS ✨

int lpfc_sc_to_bg_opcodes (struct lpfc_hba *phba , struct scsi_cmnd *sc
, uint8_t *txop , uint8_t *rxop );

like, copy it exactly bestie, don't @ me about the spacing 😭

---

🎀 ARGUMENTS 🎀

• phba — the Hba for which this call is being executed. yes, that Hba, the one you're running the call on 🦋
• sc — the SCSI command to examine 🔍 give it a little vibe check
• txop — (out) BlockGuard operation for transmitted data 📤
• rxop — (out) BlockGuard operation for received data 📥

both txop and rxop are out params, so they're where the answers get written, not where you put stuff in. periodt 💅

---

🔥 RETURN 🔥

zero on success; non-zero if tx and/or rx op cannot be determined 💀

so like — 0 is the slay outcome, anything non-zero means something couldn't be figured out, no cap.
