24505a5826d7c5cf89f3da85058befd671a73444 06-Oct-2012 Jamie Gennis <jgennis@google.com> atrace: make clock & bus bw tracing optional

This change makes enabling clock tracing and bus bandwidth tracing depend on
whether the device's kernel supports these features. If it's not supported it
will be skipped.

b9314021ee1ccaa62eb115e8e0188f482a950f3b 08-Jun-2012 Jamie Gennis <jgennis@google.com> atrace: enable running on user builds

This change allows atrace to be run on a user build, where it is not run as
root. Some command line options still require root, and atrace will refuse to
run if those options are specified when run as non-root.

This change adds the -i command line flag to atrace to enable tracing CPU idle
kernel events.

This change adds the -z command line flag to atrace to enable support for
compressing the trace with zlib as it's printed to stdout.

This change adds two command line optiosn:
-b for setting the trace buffer size
-f for enabling tracing of the CPU frequency
-l for enabling tracing of the CPU load
