Dynamic Application Loader (DAL) Host Interface (aka JHI)

Description

A daemon and libraries which allow user space applications to install Java applets on DAL FW and communicate with them.

Features

• Allows multiple client applications to communicate with Intel DAL firmware simultaneously.
• Autodetects the DAL firmware type and formats messages accordingly.
• Caches previously installed applets for easy reuse.

Dependencies

cmake
pkg-config
uuid-dev
libxml2-dev
libsystemd-dev

How to build

cmake .
make

The output directory is bin_linux.

Build options

Release build:

cmake . -DCMAKE_BUILD_TYPE=Release

Change installation location:

cmake . -DCMAKE_INSTALL_PREFIX=/user

Use SysVinit instead of systemd:

cmake . -DINIT_SYSTEM=SysVinit

Change default paths (to overcome filesystem limitations on certain systems):

cmake . -DAPPLETS_DIR=<path> -DAPP_REPO_DIR=<path>

How to install

sudo make install

How to manage the daemon

systemctl {enable|disable|start|stop|restart|status} jhi

How to check which version of JHI is installed

jhid -v

How to run without init system integration

jhid (run as root)

Alternatives:

• jhid -d (to run in the background)
• jhid 2>&1 (to redirect stderr to stdout)

Config file

Location:

/etc/jhi/jhi.conf

Options:

1. Run over mei/kernel/sockets.
2. If running over sockets, specify the IP of the server.
3. State the desired log level.
4. Change the daemon socket location.

An integartion test - bist (for internal use)

Note: The test works on Intel platforms SKL and newer.

Location:

bin_linux/bist

How to run:

./bist

All tests should pass.
