Want a driver for AMD SMN user access
The AMD system management network (SMN) is used for certain parts of the SoC to provide services. Being able to driver arbitrary read requests could be helpful to folks who are trying to develop on this platform specifically. This adds a new driver
usmn which is a child of
amdzen and a development tool to read this. This driver is not intended to be generally installed and will be in a separate package that contains other future AMD kernel development related drivers. Future work here would include things like certain kinds of error injection.
