The isci driver is for the integrated SAS controller in the Intel C600 (Patsburg) chipset. Source files in sys/dev/isci directory are FreeBSD-specific, and sys/dev/isci/scil subdirectory contains an OS-agnostic library (SCIL) published by Intel to control the SAS controller. This library is used primarily as-is in this driver, with some post-processing to better integrate into the kernel build environment. isci.4 and a README in the sys/dev/isci directory contain a few additional details. This driver is only built for amd64 and i386 targets. Sponsored by: Intel Reviewed by: scottl Approved by: scottl
