# SGX Binaries
#==========================================================================

sgx.tgz now contains two sets of binaries. One built for SGX540 and one built for SGX544.
The SGXCORE and SGC_CORE_REV is appended to the end of each file. pvrsrvinit is now a
wrapper which detects the current processor and loads the corresponding core specific
pvrsrvinit.

    omaplfb: Add omaplfb to the kernel tree

    omaplfb has dependencies on several kernel components and it will
    be easier to maintain it in the kernel tree.
    
    Sync'd to DDK omaplfb patch:
    omaplfb: Allocate a clear buffer with 8 pixel stride per GC requirement

DDK:
- Building DDK
Go through README in ddk source tree.

Build for 4430/4460
# ./build_DDK.sh -g 540 --build release

Build for 4470
# ./build_DDK.sh -g 544sc --build release

- Installing DDK
# export DISCIMAGE=<PATH TO ANDROID ROOT DIRECTORY>
# ./build_DDK.sh -g 540 --install release
# ./build_DDK.sh -g 544sc --install release

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

Make sure kernel is built before building modules

#tar -xvf ANDROID_ROOT/device/ti/proprietary-open/omap4/sgx_src/eurasia_km.tgz

# cd ANDROID_ROOT/device/ti/proprietary-open/omap4/sgx_src/eurasia_km/eurasiacon/build/linux2/omap4430_android/
# export KERNELDIR=path_to_kernel

To build for OMAP4460/OMAP4430 (SGX 540):
# make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- TARGET_PRODUCT="blaze_tablet" BUILD=release TARGET_SGX=540 PLATFORM_VERSION=4.0

To build for OMAP4470 (SGX 544 single core):
# make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- TARGET_PRODUCT="blaze_tablet" BUILD=release TARGET_SGX=544sc PLATFORM_VERSION=4.0

Once the .ko's are built, install them onto device (/system/lib/modules)

For 4460:
# cd ANDROID_ROOT/device/ti/proprietary-open/omap4/sgx_src/eurasia_km/eurasiacon/binary2_540_120_omap4430_android_release/target/
# adb push pvrsrvkm_sgx540_120.ko /system/lib/modules/

For 4470
# cd ANDROID_ROOT/device/ti/proprietary-open/omap4/sgx_src/eurasia_km/eurasiacon/binary2_544_120_omap4430_android_release/target/
# adb push pvrsrvkm_sgx544_112.ko /system/lib/modules/

Reboot device.
