Again, good stuff!
It looks to me that I-PIPE is an example of a "nested OS", with Linux nested within the I-PIPE functionality. One could take the RTAI-Fusion approach, but this measurement is of I-PIPE rather than RTAI-Fusion, right? (And use of RTAI-Fusion might or might not change these results significantly, just trying to make sure I understand what these specific tests apply to.)
Also, if I understand correctly, the interrupt latency measured is to the Linux kernel running within I-PIPE, rather than to I-PIPE itself. Is this the case, or am I confused?
