About ACPICA

ACPICA should be compiled inside kernel.

Prepare ACPICA Source Code

First download the source code from Github

git clone https://github.com/acpica/acpica.git

Then create a directory for ACPICA

cd /path/to/myOS
mkdir acpica && cd acpica

Copy ACPICA files

cp /path/to/acpica/source/include/* .
cp /path/to/acpica/source/components/{dispatcher,events,executer,hardware,namespace,parser,resources,tables,utilities}/* .

My Makefile will automatically find the source file and headers and compile them, so no need to add Makefile rules.

Configuration

The configuration of ACPICA is done via editing header files. One important header file is platform/acenv.h.
