Streaming is not working

Reported by: Matthias Vogelgesang Owned by: Suren A. Chilingaryan
Priority: major Milestone:
Component: pcilib Version:
Keywords: Cc: Suren A. Chilingaryan

Description

Streaming fails with an internally generated "Lost DMA buffers are found (non-persistent mode), reinitializing..." and thus the callback is not called.

Also pcilib_stream blocks, which is rather inconvenient. Either make it non-blocking or provide a function to set the callback independently of this function.

Lost DMA buffers is a warning message informing that inconsistent DMA buffers are detected and re-initialized. Generally, this means the last invocation of pcitool crashed and the buffers were not properly cleaned. It should not cause any problems. Buffers will be cleaned and re-initialized.

pcilib_stream is blocking. I don't like to start threads in the libraries unless there is no way around. I think the top-level should do the threading job according to the requirements set by the user. To terminate grabbing process, you may use pcilib_configure_autostop call or call pcilib_stop from the parallel thread.
