GP TEE seminar exercise
This set of files are the ones used at the annual GlobalPlatform TEE seminar (TEE Application Developers Workshop) for the session held by Linaro.
The git contains all files necessary to build a host (normal world user space
client) application and also a Trusted Application. The files located in the
host and ta folder are skeleton/template files where the attendee(s) are
supposed to fill in this missing pieces.
There is also a folder called solution, which contains the exact same set of
files, however there you will find that all functions are fully implemented. The
attendees are only supposed to have that as a last resort in case they get
stuck.
To build the binaries we have provided a little shell-script
(build-gp-conf.sh) which setup the environment variables to the toolchain,
ta-dev-kit, Client API etc. Beware that this will output the files outside this
particular git (../out/gp_conf/). The reason for this is because the attendees
are supposed to have the environment setup according to the instructions for
OP-TEE and QEMU (see 6. repo manifests).
In the solution/patch folder you will find two simple patches:
build/0001-Adds-gp_conf-ta-files-to-root-fs.patch: Applies on the build git. It just adds the lines which are needed to get the binaries included in the root FS used by QEMU.gen_rootfs/0001-Adding-a-modprobe-alias-for-quick-loading.patch: Just contains analias mpwhich save a few keystrokes at every boot (it loads optee kernel modules and tee-supplicant in one go). This patch applies to the gen_rootfs git.
