The developer +can use the default stm.bin provided or replace it with one that has +been custom built. The coreboot build system will look here for the +STM binary when the STM has been configured. + +The default STM requires a MSEG of 4MB. If a smaller MSEG is used +then the STM has to be custom built. Also, if a larger MSEG is +configured, then the STM has to be custom built to take advantage +of the additional memory. + +For version changes, issues, etc see the git repository. + +## Toolchains: + +The STM can be built with either Microsoft Visual Studio or with CMAKE/GNU. + +## ABI: + +This document defines both the firmware interface and the operating system +interface with the STM: + +SMI Transfer Monitor (STM) User Guide, August 2015 + +The above document can be obtained from firmware.intel.com. + +The STM-PE interface is defined in the Readme.STMPE file found on +the stmpe branch of review.coreboot.org/STM. + |
