[Xenomai-help] Xenomai v2.5-rc1 feedback

hi

Thanx for v2.5-rc1. Here are some minor observations

1. The prepare-kernel script requires --arch=x86 for an x86 32 bit platform.

--arch=i386 as per README.INSTALL section 2.1 does not seem to be allowed
anymore

(README.INSTALL updates required ?)

2. With Xenomai v2.4.x echoing the xenomai group id to
/sys/module/xeno_nucleus/parameters/xenomai_gid
allowed a Xenomai application to be run without having to type 'sudo'. Does
not work with v2.5-rc1.
Get the following message :

Xenomai: open: Permission denied
Xenomai: mmap(local sem heap): Permission denied

[Application runs normally if sudo is used]

Has this feature been removed ?

3. When running the latency test in a console window within X and the window
is maximised/minimized
the following message appears :

Not SIGSHADOW !

Latency test then continues to run normally

[This was seen with the 2.6.29.1 build. Will have to confirm if it appears
with the 2.6.28.9 build]

Hope this helps
Vicki

This message means that the application received a SIGWINCH not
originating from Xenomai. This is essentially a debug message which can
be removed.

This switch is still allowed. Could you send us the error output? TIA,
