smbus(7D) Devices smbus(7D) NAME smbus - System Management Bus controller driver DESCRIPTION The smbus driver is a I2C (Inter IC) nexus driver that allows the sys‐ tem to communicate with various system component chips. SMBus is a two-wire control bus based on the I2C protocol through which systems can communicate with various I2C devices connected to the bus. The smbus driver supports byte and block level transfer based on inter‐ rupt and polled mode.
