lpfc_kill_board(9)

💖 NAME 💖

okay bestie, welcome to the lpfc_kill_board(9) page — yes, that's the manual name, and we're chilling in the Kernel API Manual section. This one is literally about prepping a mailbox command for killing board ✨

lpfc_kill_board — prepare a mailbox command for killing board 🫶

---

✨ SYNOPSIS ✨

void lpfc_kill_board (struct lpfc_hba * phba , LPFC_MBOXQ_t * pmb );

that's the whole signature, no cap 💅

---

🌸 ARGUMENTS 🌸

• phba — pointer to the lpfc_hba data structure. the hba data situation, iykyk.
• pmb — pointer to the driver internal queue element for the mailbox command. that's the queue element the driver keeps internally, specifically for a mailbox command 🎀

---

🦋 DESCRIPTION 🦋

okay so here's the vibe: the kill board mailbox command is used to tell firmware to perform a graceful shutdown of a channel on a specified board to prepare for reset. iconic tidy-up energy, honestly.

when the kill board mailbox command is received, the ER3 bit is set to 1 in the Host Status register, and the ER Attention bit is set to 1 in the Host Attention register of the HBA function that received the kill board command. yes, that exact HBA function — it's giving targeted 💅

this routine prepares the mailbox command for killing the board in preparation for a graceful shutdown. so lpfc_kill_board is literally doing the pre-game for a graceful shutdown, not chaos 😌
