Seppo Ingalsuo e525c177b5 Volume: Fix for gain ramp step macro value 
This patch fixes the calculation of macro VOL_RAMP_STEP_CONST
that is used in linear step size calculation. The previous version
calculated incorrectly the value as inverse. However with used ramp
update rate of 1000 us there were no issues seen because the value
and inverse were both 1.0. The bug would have triggered with with
a faster or slower ramp update rate.

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 / Cherrytrail:

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

See unit testing documentation

Deployment

TODO: Add additional notes about how to deploy this on a live system
