2023-12-19Support timeout for interrupt semaphore24.02-rc124.02Jonny Svärd
Introduce ETHOSU_INFERENCE_TIMEOUT CMake variable to set an arbitrary timeout value that will be sent as argument to ethosu_semaphore_take() for the interrupt semaphore. Adding the ability to have a timeout for an inference. (Defaults to no timeout/wait forever.) Implement a placeholder mutex for the baremetal example and add error checks for mutex_create() call.

2023-10-11Add option to turn off logging completely23.11-rc223.11-rc123.11Jonny Svärd
Add new ETHOSU_LOG_ENABLE variable in the CMakeLists.txt to toggle logging completely off, or else by the desired severity level. Turning off the logging will also disable the LOG() macro. Change-Id: I313a97fb1569000ae22637734ef4a60eedc56f70 Signed-off-by: Jonny Svärd <jonny.svaerd@arm.com>

2021-11-01Autumn clean/refactor of NPU driverJonny Svärd
A continuation of the spring clean/refactor work. Create a better separation between driver and device(s). A short summary of what this commit contains: - Split device and driver - Simplify and hide the internal device interface - Remove (broken) abort inference functionality - Refactoring of structure - Optimizations and bugfixes Change-Id: I8988bc5f163f9ea62add2a933e4f100a82cc8d35
2021-07-08Improved Logging - Core Driver logging clean up21.08-rc321.08-rc221.08-rc121.08Anton Moberg
Made a separate header file for logging specific content. Cleaned up logging messages. Change-Id: Id329b40977156ca5b954b3a222effaedbc6b2a2c
2021-06-08Spring clean/refactor of NPU driverJonny Svärd
These changes mostly focus on creating a better structure for the driver. Creating a better separation between driver and device(s). A short summary of what this commit contains: - Move driver specific defines from device to driver - Prefix device functions with ethosu_dev - Remove device specific register access' from driver - Remove device specific debug/dump functions - Add function prototypes for weak functions - Remove legacy ARM_NPU_STUB support - Rename ethosu_device.c to ethosu_device_u55.c - Remove redundant irq handler prototype - Remove (deprecated) hardcoded instance ethosu_drv - Simplify versioning API Split driver version and hardware version/information so that driver version can be queried without a driver instance. - Improve and simplify logging Make warning the new default severity level to print and reduce severity levels to: err warning info debug - Add severity prefix to log lines. Error messages print file and line number, debug messages print function by default. - Clarify some log messages - Small optimizations and bugfixes Change-Id: I2dfbfc3a40d7eca133c82f187f422325e1e6d314
2020-12-02Remove CPU build flags from driverDaniel Anderberg
Using a cpu without proper interrupt handling is not really usefull in this context, so remove that option. Change-Id: Ie94fd9025c918eef72272e14ad5b0a95ea7dc4a4

2020-07-17MLBEDSW-2596 Add support to set driver log severityBhavik Patel
The driver can log at one of the following levels: 0=emerg, 1=alert, 2=crit, 3=err, 4=warning, 5=notice, 6=info, 7=debug. The logs at or below the set level are printed whereas the higher level logs are not printed. Change-Id: I05a498d4c8c78112207187d9dceaa2386b138c5d
2020-06-02Rework AXI patch to not depend on CMakeJonny Svärd
Make ethosu_config.h define default macro's (with default values) unless the user overrides them. For CMake users, the macros can be defined on cmd line by specifying CMAKE_C_FLAGS for cmake, like: cmake ... -DCMAKE_C_FLAGS='-DFOO=1 -DBAR=2' Change-Id: I20fd3e07fdcfb7cba58da7198fd986f8821902bb
