2022-09-13Remove CMake workaround for Arm ClangLedion Daja
Previous version of CMake did not allow CMAKE_SYSTEM_PROCESSOR to contain CPU features for Arm Clang toolchain. A workaround was added to manually strip the CPU features. Recent versions of CMake have removed this limitation and instead requires the toolchain to manually add -mcpu=<CPU+features>, which means that the workaround can be removed.

2022-08-23Fix wrong assertion in test for Ethos-U6522.08Davide Grohmann
Both version_major and version_minor for the U65 hw are set to 0, so we cannot test that they are greater than 0. So simply test that version_status is set instead. Change-Id: Ia2ac15a18c4865bdd3501c2645f644ca210d1ee1

2022-05-17Silence irrelevant compiler notes about GCC ABI incompatibilitiesDavide Grohmann
There are ABI changes between GCC 6.x and 7.1 that make them incompatible, but that is not relevant here since all software is compiled with only one GCC version. Change-Id: If82f874162404bdedc9c2e93c3a8c7a6d648fde0

2022-05-09Add support for cancelling enqueued inferencesDavide Grohmann
If an enqueued inference is cancelled it is simply removed from the queue. Both a cancel inference response with status done and a inference response with status cancelled are sent back.

2022-05-04Change return value of mutex and semaphore handling functionsLedion Daja
Changed mutex lock/unlock and semaphore take/give functions to return an int value instead of void. In addition changed FreeRTOS and message_handler applications (also FreeRTOS-based) to ignore failure of xSemaphoreGive on binary semaphores, as it does not affect the correctness of such applications. Change-Id: I023c62dc8971488107679f6dd7a5967dec0380a8
2022-05-02Avoid blocking calls in input message handler taskDavide Grohmann
