Seppo Ingalsuo a81ce180ca Volume: Get volume ramp parameters from IPC 
This patch adds code to handle volume ramp type and ramp length
parameters from topology. The previous hard coded 250 ms ramp
related macros are removed.

Since the kernel does not (yet) provide the volume min/max into
as IPC for new() the code assumes the ramp length is the length
of the mute to 0 dB gain transition.

If a volume transition is larger than that, what can happen in a
high gain configuration, the ramp is shortened to exceed the
passed time parameter. So in other words the large transitions will
use a variable rate slope.

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
