2023-08-09Add version to driver library23.08-rc1Mikael Olsson
A version has been added to the driver library so users can check if they are compatible with the driver library in use. The Python wrapper has been updated accordingly to make the version information available. Change-Id: I8affbf7068c057f7103adf14c9e4a331d547fbcc Signed-off-by: Mikael Olsson <mikael.olsson@arm.com>
2023-08-09Add kernel driver version check in driver libraryMikael Olsson
The driver library will now check that it's compatible with the kernel driver in use by checking the kernel driver's version. The kernel driver version has also been made available to the library users and the Python wrapper has been updated accordingly.

2022-10-25Added Python interface for Arm Ethos-U NPU driver library.22.11-rc1Kshitij Sisodia
Python `ethosu_driver` could be built as part of Arm Ethos-U Linux driver library CMake flow. See driver_library/python/README.md for more details. Change-Id: I177a890add5c13df9a839f4f43621f972afe5ab1 Signed-off-by: Kshitij Sisodia <kshitij.sisodia@arm.com>
2022-08-29Add linux_driver_stack testsDavide Grohmann
Change-Id: I303f1424eb46576847312672f7ed5ac03c05aee1
2022-05-05Add support for inference cancellationDavide Grohmann
Send cancel inference messages to the ethosu subsystem to abort inference execution there. Also mark inference as aborted in the linux driver stack itself, so pending inference messages are not resent when resetting the firmware. Change-Id: I244c2b119fd7995d14e3859815abf2a00c7f0583
2022-05-02Add support for rejected inference responsesDavide Grohmann

2022-04-26Fix: always close fd when destructing buffersDavide Grohmann
Also always rethrow exceptions not swallow them Change-Id: I7a4b1e408858aa0d0128ca7bd6d6a7715662f9fb
2022-04-12Drop tflite and flatbuffer dependenciesDavide Grohmann
There is not real need for the linux_driver_stack to know about tflite and flatbuffers. A better approach is to just pass the buffer to the firmware to be processes, i.e., either parsed or executed. This solves issues when linux_driver_stack and firmware are not in sync with the same library versions. Change-Id: I9b2a12e69f37f61b1ac594433a15883fb1c67b9c
2022-03-14Network infoKristofer Jonsson
Add UAPI and core message that allows user space space to fetch information about network models built into the firmware. Change-Id: Ic92529bce3edd0a5499e691a566bd065da2a72ad
2022-03-10Firmware resident modelKristofer Jonsson
Support referencing a network model by index that has been built into the firmware binary. Change-Id: Idd5294376ea82503dfeafe1203dcc0694d296dfe

2021-10-27Improve granularity of wait call in Inference classDavide Grohmann
It now accepts a timeout expressed in nanoseconds. Change-Id: I77fb89c33dc117f846b86494883548ef3241f0ab
2021-08-13Do not expose device specific hw config in capabilities21.08-rc1Davide Grohmann

2020-09-17Support inferences with multiple inputs and outputsKristofer Jonsson
Build flatbuffers library. Update network class to extract IFM and OFM dimensions from the tflite file. Update the uapi and core apis to support up to 16 IFM and OFM buffers per inference. Change-Id: I2f2f177aa4c2d5f9f50f23eb33c44e01ec2cbe09
