Callback triggered whenever DMA context state changes
@user_data [in]: User data associated with the DMA context. Will hold struct dma_resources * @ctx [in]: The DMA context that had a state change @prev_state [in]: Previous context state @next_state [in]: Next context state (context is already in this state when the callback is called)
The context is in starting state, this is unexpected for DMA.
doca_ctx_stop() has been called. In this sample, this happens either due to a failure encountered, in which case doca_pe_progress() will cause any inflight task to be flushed, or due to the successful compilation of the sample flow. In both cases, in this sample, doca_pe_progress() will eventually transition the context to idle state.
