A method is disclosed to generate and save run time data. The method supplies an embedded device comprising a processor which includes a processor cache, memory, a hardware trace facility comprising a plurality of data buffers, where the embedded device is capable of communicating with one or more host adapter ports. The method generates a trace entry, stores that trace data entry in the processor cache, and then writes the trace data entry to the plurality of data buffers.

Apparatus and method to generate and save run time data

An error handling method is provided for processing adapter errors. Rather than executing a disruptive controller hardware reset, an error handling routine provides instructions for a reset operation to be loaded and executed from cache while the SDRAM is in self-refresh mode and therefore unusable.
