| .Sh NAME | |||||
| .Nm ig4 | |||||
| .Nd Intel(R) fourth generation mobile CPU integrated I2C SMBus driver | |||||
| .Sh SYNOPSIS | |||||
| To compile this driver into the kernel, place the following lines into | |||||
| the kernel configuration file: | |||||
| .Bd -ragged -offset indent | |||||
| .Cd "device ig4" | |||||
| .Cd "device smbus" | |||||
| .Ed | |||||
| .Pp | |||||
| Alternatively, to load the driver as a module at boot time, place the following line in | |||||
| .Xr loader.conf 5 : | |||||
| .Bd -literal -offset indent | |||||
| ig4_load="YES" | |||||
| .Ed | |||||
| .Sh DESCRIPTION | |||||
| The | |||||
| .Nm | |||||
| driver provides access to peripherals attached to an I2C SMB controller. | |||||
| .Nm | |||||
| supports the SMBus controller found in fourth generation Intel(R) Core(TM) | |||||
| processors based on the mobile U-processor line for intelligent systems. | |||||
| This includes the i7-4650U, i5-4300U, i3-4010U, and 2980U. | |||||
| .Sh SYSCTL VARIABLES | |||||
| These | |||||
| .Xr sysctl 8 | |||||
| variables are available: | |||||
| .Bl -tag -width "debug.ig4_dump" | |||||
| .It Va debug.ig4_dump | |||||
| Setting this to a non-zero value dumps controller registers to console and | |||||
| syslog once. | |||||
| The sysctl resets to zero immediately. | |||||

| The | |||||
| .Nm | |||||
| driver was written for DragonFly BSD by | |||||
