OP-TEE - version 1.1.0

New features

  • Softfloat library: floating point support is now available in 32bits TA.

  • Support running 64-bits TA: on ARMv8-A platform, TA can be compiled in AArch32 and/or in AArch64 in case the core is compiled in AArch64. An example can be found in HiKey configuration file. Using the following excerpt code, the user TA libraries are compiled in both AArch32 and AArch64, and can be found in out/arm-plat-hikey/export-ta_arm32 and out/arm-plat-hikey/export-ta_arm64

    ta-targets = ta_arm32
    ta-targets += ta_arm64

  • Concurrent TA support: multiple TA can run in parallel on several cores.

  • New tests added in xtest test suite: concurrent TA (xtest 1013), floating point tests (xtest 1006 and os_test TA) and corruption file storage (xtest 20000)

  • Link to a list of all commits between this and previous release.

OP-TEE - version 1.0.0

OP-TEE is now maintained by Linaro. Contributors do not need to sign a CLA anymore, but must follow the rules of the DCO (Developer Certificate of Origin) instead.

New features

  • Add hardware support for Texas Instruments DRA7xx, ARMv7 (plat-ti)

  • GlobalPlatform™ TEE Internal Core API Specification v1.1, including ECC algorithms.

  • Secure Storage: Files stored by the REE are now encrypted. Operations are made atomic in order to prevent inconsistencies in case of errors during the storage operations. Slides describing the Secure Storage have been presented at the Linaro Connect SFO15.

  • Change of format of the Trusted Applications: they follow a signed ELF format

  • Rework thread synchronization in optee_os.

  • Use of ARMv8 native cryptographic support.

  • OP-TEE/optee_test test suite is released.

  • Introduce OP-TEE/manifest and OP-TEE/build to setup and build QEMU, FVP, HiKey and Mediatek platforms. Setup scripts that used to be in optee_os have been removed, except for Juno board.

  • Link to a list of all commits between this and previous release.

OP-TEE - version 0.3.0

New features

  • Add hardware support for
    • Mediatek MT8173 Board, ARMv8-A (plat-mediatek)
    • Hisilicon HiKey Board, ARMv8-A (plat-hikey)
  • AArch64 build of optee_os is now possible through the configuration CFG_ARM64_core=y
  • Secure Storage: Data can be encrypted prior to their storage in the non-secure. Build is configured using CFG_ENC_FS=y
  • A generic boot scheme can be used. Boot configuration is commonalized. This helps new board support. It is applied on plat-hikey, plat-vexpress, plat-mediatek, plat-stm and plat-vexpress.

OP-TEE - version 0.2.0

New features

Linux Driver Refactoring

Linux Driver has been refactored. It is now split in two parts:

  • optee.ko, the generic Linux driver. It contains all functionality common to all backends.
  • optee_armtz.ko, a specific backend dedicated to the TrustZone optee. It depends on optee.ko.

Loading the TrustZone optee linux driver module is now performed using

modprobe optee_armtz

Thanks to the dependency between the generic and the backend modules, optee.ko is then automatically loaded.

Misc new features

  • support PL310 lock down at TEE boot
  • add 64bits support (division / print)
