There seemed to be quite a bit of interest in this from the other customers, although our facility doesn't presently need this functionality. In the spirit of the "squeaky wheel", I'll squeak softly for them. >From the above web page, thus quoth the RedHawk: "In tightly-coupled symmetric multiprocessing systems such as Concurrent?s iHawk real-time systems, RedHawk Linux allows individual CPUs to be shielded from interrupt processing, daemons, bottom halves, and other Linux tasks. Processor shielding provides a highly deterministic execution environment where interrupt response is guaranteed. RedHawk implements shielding via the industry-accepted shield(1) command."
