This instrument can be used to generate an energy model for a device
based on collected power and performance measurments. The instrument
produces a C file with an energy model and an accompanying HTML report.
This instrument is very different from other instrumentation, as it
actually generates the run queue on the fly based on the operating
frequencies and idle states it discovers on the device. The agenda needs
only to contain the single "base" spec that defines the workload to be
used for performance measurement.
On some systems the temporary directory may still be "busy" after WA is
don't with it. Since it's just an empty dir and it will be reused on the
subsequent runs; do check if rm -rf succeeded.
The default value for buffer_size_file contained a path under "/d/",
which is an Android-specific alias for "/sys/kernel/debug". This commit
updates the default value to use the system-agnostic path.
Updating SysfsExtractor with a parameter to explicitly enable/disable
tempfs caching. Previously, this was determined entirely by whether the
device is rooted.
