Hi all,
I need to run xenomai on a HP Compaq nc6320. I use kernel 2.6.17.14
and xenomai 2.2.5. The non-realtime kernel runs fine on this laptop,
Means the same kernel with I-pipe (and Xenomai) disabled or the same
kernel version and .config, but unpatched?
The latter.
but the xenomai pactched kernel gives several of these messages:
IRQ routing conflict for xxxx.xx.xx.x, have irq 11, want irq 10
And some things (e.g. mouse, network) then don't work, not properly
anyway. The same kernel runs fine however on other systems.
Any clue what I can do about it?
Please provide bootlogs for both rt and non-rt kernel startup. And
the
.config.
I 'solved' it by enabling ACPI (without processor module and others).
Looks good. I don't see high latencies with the latency test. Under
what conditions might ACPI affect real-time behaviour?
CONFIG_ACPI_PROCESSOR, because it allows deep sleep states with
significant wakeup latencies.
But back to your original issue: You mean your notebook booted fine
under vanilla Linux with ACPI disabled? That would mean I-pipe relies on
ACPI here without stating this anywhere. In that case /something/ needs
fixing: code, config deps, or doc.
Just tried that. Things don't work (properly) with acpi=off (jumpy mouse,
no network, sound loops). I tried the ubuntu 6.06 2.6.15-23-386 kernel,
a vanilla 2.6.17.14 kernel and a xenomai patched 2.6.17.14 kernel. All
with same result. So that's reassuring I guess.
I recently converted my stuff from RTLinux to Xenomai and just assumed it
would be saver to turn off ACPI for real-time operation. Didn't know some
systems actually rely on ACPI.

I'm sorry. The mistake occurred to me the moment I clicked send.
