Abstract
A set of microprocessors may be set to a common mode in which the microprocessors utilize features that are common to all microprocessors. The common mode facilitates proper multiprocessor operation and permits a fix to be applied to each of the microprocessors based on this common mode. Firmware or software can detect whether microprocessors are set to run in different modes in a multiprocessor system. If not, the microprocessors are allowed to run in their normal mode, such as by writing a value to a configuration register associated with each microprocessor. If features are mixed, a different value can be written which tells each microprocessor to revert to a common mode of operation for that family of microprocessors. A common set of microcode patches may be downloaded to the microprocessors. Alternatively, the various microprocessors may also be instructed to run in a particular mode that emulates a particular stepping.
