Hi everybody,
I have a question concerning Ingo Molnar's realtime preempt patch.
This patch is great go get low latency on timer threads and a really
good real time behaviour.
I want to connect an external, embedded device via Ethernet (UDP/IP)
to my Linux PC. This communication should be in real time as well.
What is your real-time requirement? What's the response time upper
bound? I agree with the people who say this may not be right way to go.
For this I have a separate network adapter in my PC that is used
solely for this UDP Ethernet traffic.
However, I think all Ethernet traffic is be handled by
the soft IRQ threads [softirq-net-rx] [softirq-net-tx] but I do
not see a way to do real time networking via one of the network adapters.
How can I get this UDP networking real time capable?
Any feedback is welcome.
Thanks a lot!
Regards
Mathias
