#===========================================================================
#   Building SGX Kernel Modules
#===========================================================================
SGX kernel modules source is located in sgx_src/eurasia_km/

Make sure kernel is built before building modules

# cd ANDROID_ROOT/device/ti/proprietary-open/jacinto6/sgx_src/eurasia_km/eurasiacon/build/linux2/omap_android/
# export ANDROID_ROOT=path_to_android_fs_source
# export KERNELDIR=path_to_kernel_source
# export CROSS_COMPILE=$ANDROID_ROOT/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi-
# export KERNEL_CROSS_COMPILE==$ANDROID_ROOT/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi-
# export ARCH=arm
# export PATH=<path to kernel toolchain>:$PATH

To build for Jacinto6 (SGX 544 multi core):
# make TARGET_PRODUCT="jacinto6evm" BUILD=release

Once the .ko is built, install it onto device (/system/lib/modules)

# cd ANDROID_ROOT/device/ti/proprietary-open/jacinto6/sgx_src/eurasia_km/eurasiacon/binary2_omap_android_release/target/
# adb push pvrsrvkm.ko /system/lib/modules/

If you build the kernel module, it is highly advisable to replace the binaries
in your device with the ones in sgx.tgz to avoid incompatibility.

Reboot device.
