[Xenomai-help] Xenomai on x86 Asus P5LD2 mb Intel 945P chipset

[Daniele Nicolodi]

Hello,

I know this is an odd question, but I would like to save some testing
time if possible, I'm in a too tight schedule.

I need to migrate one of my data acquisition system to more recent
hardware to support a PCI-Express data acquisition board. The hardware I
may use is an x86 box built on an Asus P5LD2 motherboard: Intel 945P
chipset for Intel LGA775 Pentium 4 CPU.

Can anyone give me an hint on what kind of latency performances I may be
able to obtain from such hardware? The only reference I have been able
to find in the archives is this

https://mail.gna.org/public/xenomai-help/2007-02/msg00308.html

where latency problems, probably related to SMI, are reported, but with
an old version of Xenomai. Does someone have another data point that I
may interpolate from?

Thank you. Cheers,

Daniele

The issues on that hardware at that time have been solved. We still
have a number of such machines. They run fine. I use Xenomai 2.5.? with
the appropriate kernel for it.

Good luck,
Theo

Hello Theo, thank you for confirming that this kind of hardware plays
nice with Xenomai. I'll tests my hardware ASAP.
