Since SES specs do not define mechanism to map enclosure slots to SATA disks, AHCI EM code I written many years ago appeared quite useless, that always bugged me. I was thinking whether it was a good idea, but if LSI HBAs do that, why I shouldn't? This change introduces simple non-standard mechanism for the mapping into both AHCI EM and SES code, that makes AHCI EM on capable controllers (most of Intel's) a first-class SES citizen, allowing it to report disk physical path to GEOM, show devices inserted into each enclosure slot in `sesutil map` and `getencstat`, control locate and fault LEDs for specific devices with `sesutil locate adaX on` and `sesutil fault adaX on`, etc. I've successfully tested this on Supermicro X10DRH-i motherboard connected with sideband cable of its S-SATA Mini-SAS connector to SAS815TQ backplane. It can indicate with LEDs Locate, Fault and Rebuild/Remap SES statuses for each disk identical to real SES of Supermicro SAS2 backplanes. MFC after: 2 weeks |

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
