Seppo Ingalsuo 90a6efd154 TPLG: Change volume capture pipeline gain range to -50 .. +30 dB
This patch replaces the -64 to 0 dB volume scale for capture with
more practical -50 to +30 dB gain. The step is 1 dB. It allows to
compensate for different microphone model sensitivities when constant
acoustical decibels to digital decibels level is needed in a
microphone capture application.

Prerequisites

  • Docker
  • CMake (version >= 3.10)

Build Instructions

  1. Create directory in checked out repo for build files:
mkdir build && cd build
  1. Run configuration for your toolchain:

Baytrail:

cmake -DTOOLCHAIN=xtensa-byt-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-byt-elf ..

Cherrytrail:

cmake -DTOOLCHAIN=xtensa-cht-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-cht-elf ..

Haswell / Broadwell:

cmake -DTOOLCHAIN=xtensa-hsw-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-hsw-elf ..

Apollolake:

cmake -DTOOLCHAIN=xtensa-apl-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-apl-elf ..

Cannonlake:

cmake -DTOOLCHAIN=xtensa-cnl-elf -DROOT_DIR=`pwd`/../../xtensa-root/xtensa-cnl-elf ..
  1. Apply default config for your platform.

Baytrail:

make baytrail_defconfig

Cherrytrail:

make cherrytrail_defconfig

Haswell:

make haswell_defconfig

Broadwell:

make broadwell_defconfig

Apollolake:

make apollolake_defconfig

Cannonlake:

make cannonlake_defconfig
  1. (Optional) Customize your configuration
make menuconfig
  1. Build firmware
make bin
# or `make bin -j<jobs>` for parallel build

Running the tests
