Provider: Embedded Linux The MinnowBoard project is an open hardware platform that uses Intel Architecture. While the project, overall, is focused on hardware there are a lot of things surrounding this effort that can, and are, useful both to the project and to the greater open source community. As such the MinnowBoard project (from a GSoC perspective) is more of an umbrella giving a home to a number of other projects to collectively work on and around the enablement of the MinnowBoard. The SMBus 3.0 specification was recently released, and Linux does not fully support the changes to the specification, and the MinnowBoardMax drivers do not fully support the specification. The SMBus driver architecture and API needs to be updated as well as adding full support for MinnowBoardMax. There are Haskell modules available for USB and UART, but not for I²C/SMBus/PMBus. Tool builders and robotics enthusiasts in the functional programming community could use supporting modules.

Provider: mjm wired (Mauriat Miranda) This driver supports hardware montoring for various PMBus compliant devices. It supports voltage, current, power, and temperature sensors as supported by the device. Each monitored channel has its own high and low limits, plus a critical limit. Fan support will be added in a later version of this driver.

Provider: mjm wired (Mauriat Miranda) While PMBus commands are standardized, there are no mandatory commands, and manufacturers can add as many non-standard commands as they like. Also, different PMBUs devices act differently if non-supported commands are executed. Some devices return an error, some devices return 0xff or 0xffff and set a status error flag, and some devices may simply hang up. Despite all those difficulties, a generic PMBus device driver is still useful and supported since Linux kernel version 2.6.39. However, it was necessary to support device specific extensions in addition to the core PMBus driver, since it is simply unknown what new device specific functionality PMBus device developers come up with next.

When connected to an active bus, the MIIC-101 Bus Monitor can collect, display or upload information on all bus activity.
