[PATCH 0/3] *** new features for alsabat ***

[han.lu]

From: "Lu, Han" <han.lu@intel.com>

Add 3 features for alsabat:
    1. add default device name for playback and capture
    2. add standalone mode, to bypass data analysis
    3. add bash test script to cover basic alsabat features

[PATCH 1/3] alsabat: add default device name for playback and capture

[han.lu]

From: "Lu, Han" <han.lu@intel.com>

Add default name for the playback and capture devices, in case
they were not set by user through '-D', '-P' or '-C' options.
Previously, if no device be specified, the alsabat will start
a playback thread and a capture thread, and then exit the
threads with error log.
If only one of playback and capture is specified, the alsabat
will work on single line mode as before, where only one thread
(playback or capture) will be started.
The patch was tested on Ubuntu and Chrome OS.

[PATCH 2/3] alsabat: add standalone mode

[han.lu]

From: "Lu, Han" <han.lu@intel.com>

Add support for standalone mode where alsabat will run on a
different machine to the one being tested.
In standalone mode, the alsabat just generates, playback and
capture sound data like in normal mode, but does not analyze.
The alsabat being built without libfftw3 support is always work
in standalone mode.
The alsabat in normal mode can also bypass data analysis using
option "--standalone".

[PATCH 3/3] alsabat: add bash test script

[han.lu]

From: "Lu, Han" <han.lu@intel.com>

Add bash script for alsabat feature test. It covers basic alsabat
features, including waveform and wav file generate, playback,
capture and analysis with configurable parameters under different
work modes. (loopback, single line, standalone and local mode)
Usage examples:
        alsabat-test.sh
        alsabat-test.sh plughw:1,0
        alsabat-test.sh plughw:1,0 plughw:1,0
