Source Code Control


Ftrace evaluation extracts performance data from ftrace files. The usage is

./ [-abfhilmopqrtv] PROGUNIT FILES

The options control what data is extracted from the ftrace file, at least one has to be specified (use -h to find out about their significance). PROGUNIT is the name of the subroutine or ftrace region and FILES is a file name or regular expression containing the text output of ftrace.
