The controllers managed by mpi3mr driver requires system memory to save hardware and firmware diagnostic information, this patch set enhances the drivers to provide host memory to the controller for diagnostic information. This patch set also provides driver changes to push kernel messages into the diagnostic buffers reserved for the driver, so that the information will be available as part of debug data fetched from the controller. In addition, support for configuring automatic diagnostic information is added in the driver.
