Seppo Ingalsuo 7a0d5f6246 EQ FIR: Updates for component initialization and cache functions 
This patch delays FIR initialization until prepare() to avoid unnecessary
initialization for not final channels amount when in idle. It avoids
a number of malloc and free operations. The FIR delaylines allocation
is brought easier visible via addition for FIR delay address and size
pointers to component data. There's no more need to look it up from inside
of FIR channel instances.

The FIR channel bypass feature is now supported with assign of response
number -1 into channel similarly as in IIR. The same change is done
for generic C and optimized FIR cores.

The cache invalidate functions are cleaned up to perform the operation
into single allocated buffer instead of multiple.

FIR reconfigure during playback is prevented due to still incomplete
implementation for runtime changes.

Prerequisites

  • Docker

Build Instructions

  1. Run autogen.sh

  2. Build and install the rimage ELF image creator and signing tool

./configure --enable-rimage
make
sudo make install
  1. Run the following configure based on your platform.

Baytrail :-

./configure --with-arch=xtensa --with-platform=baytrail --with-root-dir=$PWD/../xtensa-root/xtensa-byt-elf --host=xtensa-byt-elf

Cherrytrail :-

./configure --with-arch=xtensa --with-platform=cherrytrail --with-root-dir=$PWD/../xtensa-root/xtensa-byt-elf --host=xtensa-byt-elf

Library for Host Platform :- If building library for host platform, run the following configure. Please modify the --prefix option to choose the directory for installing the library files and headers

./configure --with-arch=host --enable-library=yes --host=x86_64-unknown-linux-gnu --prefix=$PWD/../host-root/

  1. make

  2. make bin

End with an example of getting some data out of the system or using it for a little demo
