The GNUmakefile in this directory prepares ``/lib/firmware/intel/sof/`` and
|
|
``/lib/firmware/intel/sof-tplg/`` directories.
|
|
|
|
It extracts what's needed from the output of the scripts
|
|
``./scripts/xtensa-build-all.sh`` and ``./scripts/build-tools.sh -T
|
|
-l``. It automatically runs these scripts when needed for the platforms
|
|
listed in config.mk and performs incremental builds when they have
|
|
already been run.
|
|
|
|
It does not copy anything to ``/lib/firmware/`` directly but to local,
|
|
"staging" subdirectory first. The staging area can then be installed with
|
|
rsync to a local or remote ``/lib/firmware/intel/`` or to a release
|
|
location. This gives an opportunity to inspect the staging area and
|
|
avoids running everything as root.
|
|
|
|
The default target (re-)generates the staging area:
|
|
|
|
make -C installer/
|
|
|
|
Then, to install the staging area:
|
|
|
|
sudo make -C installer/ rsync
|
|
|
|
By default, the "rsync" target installs to the local
|
|
``/lib/firmware/intel/`` directory. To install to a different host or
|
|
different directory, copy the ``sample-config.mk`` file to ``config.mk``
|
|
and follow the instructions inside the file. ``config.mk`` can also be
|
|
used to change the list of platforms installed and a number of other
|
|
Make variables. As usual with Make, many parameters can also be
|
|
overridden on the command line.
|
|
|
|
To stage and install in one go:
|
|
|
|
make -C installer/ stage rsync
|
|
|
|
"stage" is the default target and it tries to stage everything:
|
|
firmware, dictionaries and topologies. As usual with Make, it's possible
|
|
to invoke individual targets. Find a list of targets at the top of
|
|
GNUMakefile.
|
|
|
|
You can use `make -jN stage` to build multiple platforms faster but do
|
|
*not* `make -jN stage rsync` as this will start deploying before the
|
|
builds are all complete. That's because we want the rsync target to be
|
|
able to deploy subsets. Instead do: `make -jN somethings && make rsync`.
|
|

|
Sample output:
|
|
|
|
staging/sof: symbolic link to sof-v1.6.1
