Both 3124-1 (1.5 Gbps) and 3124-2 (3 Gbps) 42versions of the 3124 chip are supported. 43.Pp 44Although 45.Nm 46controllers are actual ATA controllers, the driver emulates SCSI via a 47translation layer. 48.Sh LOADER TUNABLES 49The following hints may be set in 50.Xr loader.conf 5 51to control the 52.Nm 53driver's behavior. 54Note that the hint need only exist, so removing it requires commenting it out. 55.Pp 56Usually both the 57.Xr nata 4 58and the 59.Nm 60drivers are loaded. 61The 62.Xr nata 4 63driver will pick up any ata-like devices which the 64.Nm 65driver misses. 66If the 67.Nm 68driver is disabled the 69.Xr nata 4 70driver will typically pick up the 71.Nm 72devices, albeit under the 73.Pa ad 74disk name rather than the 75.Pa da 76disk name. 77.Bd -literal -offset indent 78hint.sili.disabled=1 79.Ed 80.Pp 81The 82.Nm 83driver can be told to force a lower-speed 1.5Gb link speed 84if necessary, and can also be told to refrain from attempting to send 85certain higher-level ATA commands to initialize ATA features which 86some devices might not properly implement. 87.Bd -literal -offset indent 88hint.sili.force150=1 89hint.sili.nofeatures=1 90.Ed 91.Pp 92The 93.Nm 94driver supports MSI but support is turned off by default. 95It can be enabled by setting the 96.Va hw.sili.msi.enable 97tunable to 1. 98.Sh SEE ALSO 99.Xr ahci 4 , 100.Xr intro 4 , 101.Xr nata 4 , 102.Xr nvme 4 , 103.Xr pci 4 , 104.Xr scsi 4 , 105.Xr loader.conf 5 106.Sh HISTORY 107The 108.Nm 109driver first appeared in 110.Dx 2.3 . 111.Sh AUTHORS 112.An -nosplit 113The 114.Nm 115driver was originally written by 116.An David Gwynne Aq Mt dlg@openbsd.org 117and 118.An Christopher Pascoe Aq Mt pascoe@openbsd.org 119for 120.Ox . 121.Pp 122It was ported to 123.Dx 124by 125.An Matt Dillon Aq Mt dillon@apollo.backplane.com , 126who added new features such as hot-plug and port multiplier support. 127
