TLK-D can be compiled by including it in the -platform's makefile. TLK is primarily meant to work with Tegra SoCs, so until -Trusted Firmware starts supporting Tegra, the dispatcher code can only be -compiled for other platforms. - -In order to compile TLK-D, we need a BL32 image to be present. Since, TLKD -just needs to compile, any BL32 image would do. To use TLK as the BL32, please -refer to the "Build TLK" section. - -Once a BL32 is ready, TLKD can be included in the image by adding "SPD=tlkd" -to the build command. - -Trusted Little Kernel (TLK) -=========================== -TLK is a Trusted OS running as Secure EL1. It is a Free Open Source Software -(FOSS) release of the NVIDIA® Trusted Little Kernel (TLK) technology, which -extends technology made available with the development of the Little Kernel (LK). -You can download the LK modular embedded preemptive kernel for use on ARM, -x86, and AVR32 systems from https://github.com/travisg/lk - -NVIDIA implemented its Trusted Little Kernel (TLK) technology, designed as a -free and open-source trusted execution environment (OTE). - -TLK features include: - -• Small, pre-emptive kernel -• Supports multi-threading, IPCs, and thread scheduling -• Added TrustZone features -• Added Secure Storage -• Under MIT/FreeBSD license - -NVIDIA extensions to Little Kernel (LK) include: - -• User mode -• Address-space separation for TAs -• TLK Client Application (CA) library -• TLK TA library -• Crypto library (encrypt/decrypt, key handling) via OpenSSL -• Linux kernel driver -• Cortex A9/A15 support -• Power Management -• TrustZone memory carve-out (reconfigurable) -• Page table management -• Debugging support over UART (USB planned) - -TLK is hosted by NVIDIA on http://nv-tegra.nvidia.com under the -3rdparty/ote_partner/tlk.git repository. Detailed information about -TLK and OTE can be found in the Tegra_BSP_for_Android_TLK_FOSS_Reference.pdf -manual located under the "documentation" directory_. - -Build TLK -========= -To build and execute TLK, follow the instructions from "Building a TLK Device" -section from Tegra_BSP_for_Android_TLK_FOSS_Reference.pdf manual. - -Input parameters to TLK -======================= -TLK expects the TZDRAM size and a structure containing the boot arguments. BL2 -passes this information to the EL3 software as members of the bl32_ep_info -struct, where bl32_ep_info is part of bl31_params_t (passed by BL2 in X0) - -Example: --------- - bl32_ep_info->args.arg0 = TZDRAM size available for BL32 - bl32_ep_info->args.arg1 = unused (used only on ARMv7) - bl32_ep_info->args.arg2 = pointer to boot args - |
