lpfc_config_port(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

lpfc_config_port β€” bestie, this is the one that preps a mailbox command for configuring the port πŸ’– (the manual itself lives under Kernel API Manual, iykyk)


✨ SYNOPSIS ✨

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

πŸŽ€ ARGUMENTS πŸŽ€

  • phba β€” pointer to the lpfc_hba data structure. yes it's the hba. it's always the hba. 🫢
  • pmb β€” pointer to the driver's internal queue element for the mailbox command. that's the lil envelope you're stuffing πŸ“¬

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so the configure port mailbox command has ONE job and it's iconic: it identifies the Port Control Block (PCB) in the driver memory. that's it. that's the whole vibe. πŸ‘‘

but listen β€” after this command is issued, the driver must not access the mailbox in the HBA without first resetting the HBA. no cap. not even a little peek. πŸ™ˆ

the HBA may copy the PCB information to internal storage for subsequent use, and the driver cannot change the PCB information unless it resets the HBA. so like… the HBA takes a screenshot and the driver is not allowed to edit the post. πŸ’€

and that's the whole point of this routine: this routine prepares the mailbox command for configuring port. literally the entire job. slay. ✨
