🦋 isci(4) — your Kernel Interfaces Manual bestie 🦋

okay so boom 💥 this is the page for isci(4), and yes bestie it lives in the Kernel Interfaces Manual — we're talking Intel C600 Serial Attached SCSI driver energy. let's go 🫶

💖 NAME 💖

isci — the Intel C600 Serial Attached SCSI driver. that's the whole name, no notes, iconic.

✨ SYNOPSIS ✨

ok bestie, here's the tea: to compile this driver into your kernel, place these lines in your kernel configuration file:

device scbus
device isci

or, if you'd rather load the driver as a module at boot, place this line in loader.conf(5):

isci_load="YES"

🎀 HARDWARE 🎀

the isci driver provides support for Intel C600 SAS controllers. that's it, that's the hardware vibe. 🎀

🌸 CONFIGURATION 🌸

to force legacy interrupts for all isci driver instances, set the following tunable value in loader.conf(5):

hw.isci.force_legacy_interrupts=1

🔍 DEBUGGING 🔍

to enable debugging prints from the isci driver, set the

hw.isci.debug_level

variable to a value between 1 and 4 in loader.conf(5). noted, bestie. 📝

also: the hardware layer in the isci driver has extensive logging capabilities which are disabled by default for performance reasons. these can be enabled by adding

options ISCI_LOGGING

to the kernel configuration file. boom, logs. 🔥
