This README file is provided for customers to build the sample kernel-extension event-producer provided (testKext) and test it. ------------------------------------------------------------------------ Steps: 0) Use the "Makefile" to build the testKext if it is not built. 1) As a root user, load the kernel extension by typing: ./kexload -l testKext 2) Check the availability of the event producer "sampleKextEvProd" by typing: cat /aha/evProds.list Sample output is: sampleKextEvProd <<<<< Note this vmo waitTmPgInOut waitersFreePg schedo waitTmCPU modFile utilFs 3) Start monitoring the event as a consumer from another window, by typing: /usr/samples/ahafs/bin/aha -m /aha/sampleKextEvProd.monFactory/sampleKextEvent.mon 4) Trigger the event by typing: ./triggerEvent 5) The consumer should see an output like this: The event corresponding to the AHA node \ /aha/sampleKextEvProd.monFactory/sampleKextEvent.mon has occurred.
