This patch adds the Kconfig option COMP_SRC_IPC4_FULL_MATRIX and
adds handling to src.c. Testbench build was changed to use this
largest matrix.
The coefficients were generated with script src_ipc4_int32.m. The
new sample rates were added to test script src_test.m.

This patch adds to command line switch -n for output channels count.
Existing -c is for in channels, new -n is for out channels count. Out
channels count is same as input if -n is not present. Switch -q is
added to quiet the trace output if it is not needed.
The Matlab language test scripts for components are updated to use
the -t config.sh interface of comp_run.sh. It allows more flexible
control of input and output streams.

The main change in this patch is to allow process_test to use
frequency dependent masks for frequency response and THD+N. It
allows tests with pass/fail criteria for components like EQs
and DCblock. SRC test not really changed but the small changes
in passing test controls are updated there as well.
In EQs tests the process test can decode the theoretical response
from setup blob. The measured frequency response is compared to
that.
The test print and plot output look is improved for nicer reports.
The runtime plots opening is disabled for batch mode operation
but the plots now appear to test output directory in png format.

This patch adds an Octave test script process_test.m to audio processing
components like FIR and IIR EQ.
Parts of src_test.m are moved to common functions to ease printing of
test results matrix.

Gain of SRC varies by 1 dB due built-in attenuation in the filter
coefficients. It was added to avoid signal overshoots to distort
with some challenging music content. When a converter consists of
two filters in series the attenuation duplicates. While SRC is
missing the gain compensation the test criteria needs to be relaxed.

This patch adds a shell script sof_test_perf.sh that measures
gain, frequency response, and total harmonic distortion plus
noise for a remote device.
Matlab or Octave is needed. The shell script launches by default
Octave to process the signal generation and test results analysis
scripts.
The remote device must be set to be accessible by ssh without
passwords. An external high quality USB sound card is recommended
as analog interface to connect to test device's analog interface.
The configuration file sof_test_perf_config.m must be edited for
the remote device's user account, audio device, audio format, and
capture sound card audio device, and audio format.

The tests created lot of unnecessary fails when testing with S16_LE
format. The test pass criteria for THD+N, DR is relaxed for tests
with 16 bit data.
Since the gain of SRC conversions was lowered to -1 dB the test
case for gain need to be updated. The gain is retrieved from
src_param() function. An exception is added for FS1 == FS2 case
when data is passed through. In that case expected gain is 0 dB.
The frequency response measurement grid does not necessarily cover
the exact upper frequency of pass-band. Therefore the min. upper
passband frequency is scaled by 0.99. This avoids measurement
technique related fails in test.
The chirp spectra test case was updated to use for RMS level criteria
for testing the level of signal. The peak level was less robust and
caused unnecessary test fails.
The option to not open plot windows during test is set. It improves
speed of test and avoids display clutter.

This patch adds 50 kHz into SRC generator script for std and tiny
profiles. The src generator script is cleaned up and the default
conversion matrix is moved into caller script for easier maintenance.
The plots appearance is improved and the generated coefficients code
look is improved to pass the git pre- and post-commit script
requirements.
The SRC test bench scripts are updated for changed locations. A SRC
playback topology is used for test bench and real device usage.
