[Xenomai-help] building xenomai integrated drivers

[Kim Chuan Lim]

Hi ya,

The following is my .config..

#
# Drivers
#
CONFIG_XENO_DRIVERS_16550A=y
CONFIG_XENO_DRIVERS_TIMERBENCH=y
CONFIG_XENO_DRIVERS_IRQBENCH=y
CONFIG_XENO_DRIVERS_SWITCHTEST=y


I try to look for xeno_16550A.ko in my computer but i cannot get it.
There is nothing such folder namely "xenomai "in my
/lib/modules/2.6.17-default/kernel/drivers/

May i know how could i build it manually?

Regards,
Kim Chuan.

You compiled them into the kernel ("=y" instead of "=m" for modular
build). Nothing special here.

[Xenomai-help] Xenomai & Elinos

[GUARDIOLA-FALCO Sebastien 204282]

Hello,

I believe some people wanted to know which version of Xenomai is currently supported by ElinOS (Sysgo).
This is the 2.0.4, patched to a 2.6.15 kernel, but I'm only talking about PowerPC archs (don't know others).
What can I expect of this Xenomai version? what has been mostly improved since then?

Thanks,
Sébastien Guardiola Falco.

Thanks for the info. Yeah, I meanwhile read this as well in some
publicly available data sheet. Just the precise patch level remained
unclear.

What did they patched, only I-pipe? What I-pipe version is the patch
based on?

See the ChangeLog of a recent Xenomai version... :)

A lot of stuff has improved since then, e.g. the performance
enhancements due to pipeline head optimisation or the shared IRQ
support. And I bet that a few recent bug fixes are missing in the 2.0
series as well (one may correct me, it's a subjective impression). The
same may be true for the I-pipe patch.

It would be really a pity if they have patches of common interest for
Xenomai/I-pipe, even if only for 2.0.x, and did not posted them yet...

2.0.x is in deep maintenance mode, which means that only real
showstoppers are fixed when there is no work-around, and only for
subsystems which were complete and not work-in-progress at the time of
the initial 2.0 release. IOW, no optimization, no ahead of bug report
fixes, no new architecture support, no new interfaces, no documentation
update, just plain brown paper-bag bug fixes if any.

2.0.x can use any of the recent I-pipe patches, but won't benefit from
the recent optimizations they bring, like wired interrupt support,
though.

Hi Jan,

Instead of using modprobe, what should i do to load the driver?

Regards,
Kim Chuan.

Nothing. The driver is already loaded and the initialisation code is
executed on system boot.

And for configuring the 16550A when it's built in see
doc/txt/16550A-driver.txt.
