SUBJECT: I'm looking for someone who succeeded to use NWIS / Microcase cpu-analyzer with 680x0-probes for measurements on a particular process run on UNIX V.3 (AT&T 68000). SHORT DESCRIPTION OF THE NWIS-TOOL: The cpu-analyzer works (by many other features) like software profiling in unix BUT it does not affect measurements (no profiling overhead) and you do not have to recompile your application, in fact you can take any 3rd party product and see which address ranges they are using often, which are not used etc... You can also see how good test coverage you have in your system test (only 30% of total program code???). I found the tool very powerful and useful, even if I weesh that the number of events/symbols which can be presented by the tool could be bigger. WHAT I'M LOOKING FOR: We was able to do this on a Philips V.2 MPX P9X00 systems. There the kernel team has added two flags in the kernel: one saying that my process has been activated and one saying that my process is not running any longer. Using accesses to these addresses as trigger we could follow a process. Of cause it was also a command to tell kernel which process id that was ment to be supervized. The question is: "Does AT&T UNIX V.3 some good addresses (symbols) one can trig on? Or perhaps there are already things prepared for external analyzers? Help! Help! Help! Help! Help! Help! Help!
