ABSTRACT:
A method and apparatus for providing trace fault information to a trace fault handler. The trace fault information is evaluated prior to beginning execution of a micro code flow. The evaluated trace fault information is stored in a buffer and the micro code flow is executed. While the micro code flow is executing, if a micro code instruction of the micro code flow is executed that enables tracing, the trace fault information stored in the buffer is written to a data storage area. The data storage area is accessible to the trace fault handler.
