Subject: CONFIG_PREEMPT_RT Patch and UDP/IP on Ethernet in real time.
Date: Mon, 16 Jul 2007 16:28:14 +0200 (CEST) [thread overview]
Message-ID: <9335978.1184596094749.JavaMail.ngmail@webmail12> (raw)
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.
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 my dedicated network adapter.
How can I get this UDP networking real time capable?
I use kernel 2.6.21.6 and the related realtime preempt patch.
However, this is a general question that is not related to a certain kernel
version.
Any feedback is welcome.
Thanks a lot!
Regards
Mathias
