Latencies of socketCAN/netdev vs. chardev

Post by ckeydel » Thu 31. Oct 2019, 09:51

Hello,

There is old information about problems with message lag/latencies when using socketCAN/netdev, for example caused by dynamic memory allocation in the Linux networking stack. Is this still a problem? Do you see people choose the chardev driver over netdev for the purpose of getting better realtime behaviour?

Cheers,
Chris

Hi,

no, never heard about such a problem, but simply test it on your system.
