Hello Karim,
after reading your mail about the use of the LTT together with the RTNET
module, I would like to ask you some questions:
- You wrote that the response time is <=65 microseconds. What is the
maximal throughput over the ethernet connection? What is the maximal packet size?
Is this the MTU value and is this value fixed or can it be changed?
- I asume that the interrupt of the network card is handled as a realtime
interrupt (by RTAI) and not as a normal linux interrupt. (It's shown this
way in your screenshot) Is this correct? Does the response time (or the
throughput) change under load?
- When will your network card drivers be released? Do you (or anybody here
on the list) know when the next version of the RTNET module will be
released (and what cards will be supported)?
- In your package TracePackage-0.9.3.tgz you included patches named:
patch-ltt-rtai-22.2.4-000822 and
patch-ltt-linux-2.2.16-with-rtai-22.2.4-000822
As there is no RTAI-22.2.4 on the RTAI website, and the version of RTAI
for the linux kernel version 2.2.16 is RTAI-1.4, I think your patches are for
this version?
Thank your for making your work available to the public.
Bye,
Joachim
