lpfc_stop_port_s4(9)
π lpfc_stop_port_s4(9) β bestie's guide to shutting an SLI4 port tf down
okay so this is a page from the Kernel API Manual (yes, the whole manual, and yes, we're reading it for fun now π«Ά). it's about one lil function called lpfc_stop_port_s4, and honestly? she's short but she's got range.
β¨ NAME β¨
lpfc_stop_port_s4 β stop SLI4 device port. that's it. that's the whole name, and she ate π
πΈ SYNOPSIS πΈ
void lpfc_stop_port_s4 (struct lpfc_hba *phba );
return type void, so like... she gives nothing back and that's iconic of her. no notes. π₯
π ARGUMENTS π
phbaβ pointer to thelpfc_hbadata structure. literally just a pointer to the hba struct, that's the whole vibe. that's the entire energy she brings. π
π DESCRIPTION π
okay so bestie, here's the tea β β this routine gets invoked to stop an SLI4 device port. like, the port is done, the port is logging off, the port said "i'm going home."
what does stopping actually mean here? two things, and only two things, don't @ me:
- it stops the device from generating interrupts π
- it stops the device driver's timers for the device β°
so no more tapping you on the shoulder (interrupts) and no more sneaky little alarm clocks going off (timers). it's giving "lights off, phones down, everyone go to bed." no cap. π΄π
π¦ SEE ALSO π¦
okay so this is the part where the manpage goes FULL group-chat and tags literally everyone. i'm not skipping a single one of these besties β the whole squad, in original order, no crumbs left behind. π β¨

like i said. the whole squad. 217-ish besties and we tagged every single one, no gatekeeping π«Άπ
ngl if you were hoping for a shorter list... this is a kernel manpage, babe. we don't do short here. π
and that's the whole page!! mwah π this lil beauty comes from ./drivers/scsi/lpfc, and she's stamped October 2026 β so yes, she's from the future, and yes, she's still just stopping interrupts and timers. slay, honestly. πβπ
