2022-05-23Use ids for identifying messages sent to EthosU firmwareDavide Grohmann
Avoid to use pointers to kernel memory as identify messages, prior this change, if memory is reused that can lead to unexpected conflicts. Remove ref counting from capabilities and network_info since memory is freed in only one place. Finally, extract the capabilities code in its own files.

2022-05-09Reset firmware when inference cancellation fails22.05-rc1Davide Grohmann
If an inference fails to be cancelled and it is still in a pending state, reset the whole firmware. Indeed the assumption is that something is at fault on the firmware side and it is not progressing. Change-Id: I2f568b2167d86cda3cb96a5e83551b018f5fc55d
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
2022-04-04Reset firmwareKristofer Jonsson
Reset the firmware if it becomes unresponsive. Use ping to send keep alive requests. Only monitor ping and inference request messages. The other messages pass no resources to the firmware and can be cancelled without resetting the firmware. Change-Id: Ifbcc370f02d79a64f25598f11376a1dc84a7a066
2022-03-23Kernel watchdog timeoutKristofer Jonsson
Implement kernel watchdog that detects when firmware becomes unresponsive. Change-Id: I5c5b58a56a2ce629e1fd7cabae83b61823239ea6
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
2021-06-10Add support for handling capabilities requestsDavide Grohmann

2021-01-26Improve mailbox message handlingJonny Svärd
Introduce a 32b magic for each message. Verify the magic for all incoming messages. Add reset function - in case of protocol error, effectively reset/empty the incoming queue. Add an error message type and message Add version request/response Verify payload length of responses (when applicable) Change-Id: I8aadd4012024492533d52e2cdb38630fce5c36e2
2020-11-16Add PMU config to inference creationPer Åstrand
Add PMU configuration information to inference creation. Change-Id: Id8a69517a5d3e4822dbaf46f76cadb2700b3d981
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
