2022-05-18Check size of buffer before allocatingPer Åstrand
Avoid undefined behaviour from calling dma_alloc_coherent with requested size=0 as reported by UBSAN. Change-Id: I1732759464f1d88259edeea099b1729f4ae6b86f
2022-05-18Replace usage of forbidden strncpy with strscpyDavide Grohmann
strscpy copies max destination size -1 chars and ensures NULL termination. It also return an error if the destination buffer is too small. Change-Id: I88e9e5020b2b26ca50c12ae845dad070855a8bde
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
2022-05-02Add support for rejected inference responsesDavide Grohmann

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

2021-11-01Increase message timeoutPer Åstrand
Bump the hardcoded timeout value to allow for userspaces process to be scheduled and receive the response from the capabilities request. Change-Id: Ia2c8a0554870cf8470a2bb40bf8ed450c10f8446
2021-10-18Use minor number for device nodeKristofer Jonsson
Allocate a range of minor numbers and use the minor number as index when creating the /dev/ethosu<nr> device node. Change-Id: I76c2a3995ff5087e42a4e95945eb884a4bfb58f6

2021-08-12Fix: do not attempt to read data from mailbox when length is 0Davide Grohmann
Also add a call to send a ping message in the inference_runner example app. Change-Id: Ia2b4abf5fec8285c320ec0f28df167ff2ea13d82

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
