2022-05-19Add sentinel entry to dt array22.05-rc322.05-rc222.05Per Åstrand
Change-Id: Ic5d98c108593a16034c7dbc18043bbee13c31833
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

2022-04-27Adapt remoteproc module for more kernel versionsPer Åstrand
The .da_to_va has different signatures for different kernel versions. Add kernel version checks to pick the correct one. Change-Id: Ie25c496aa646119526867c91f244f9ad195860cd
2022-04-26CoverageKristofer Jonsson
Add scripts for gathering coverage data on target, and analyzing coverage info on host. Change-Id: I3bb2d0ec3757ce077638a8780779daa84cd48686
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
2022-04-04Reset 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

2021-11-15Fix: do not leak file descriptors on errorsDavide Grohmann
When bailing out on errors in the constructors of Buffers or Networks, the open file descriptor should be closed since the descructor will never be called. Change-Id: I8e1954e9efd65b594cc9544e18d0bfbe0730f156

2021-10-28Add utility to print firmware logKristofer Jonsson
