[Xenomai-core] xeno-test updates [rfc patch]

[Jim Cromie <jim.cromie@domain.hid>]

[-- Attachment #1: Type: text/plain, Size: 2141 bytes --]



Ive started adding to xeno-test, as outlined previously (plus some)

- now run cyclictest and switch, in addition to latency -t 0,1,2

-  changed the prewired -m email-addy to xenotest.output@domain.hid
will change again when something is formalized.
In meantime, feel free to send results, Ill periodically bundle them,
and/or just forward them automatically.

- added `cat /proc/xenomai/* /proc/xenomai/*/*` to boxstatus(),
which is run before and after latency tests.
Note that /proc/ipipe/* is catted in boxinfo(), which is only run before,
since the info doesnt change

- moved cat /proc/meminfo to boxstatus, since it changes (a little bit)

- now grep more config-items out of config (for non-verbose mode)
   latency-killers, PREEMPT, others ?

- now fetch .config from /lib/modules/`uname -`/build, unless 
/proc/config.gz is there.

- -v flag gets whole config (from either source)

- boxinfo now runs xeno-info, xeno-config

- added  From: <xenotest.sender@domain.hid> to outgoing email.
This probably isnt good enough, as mailservers generally check real 
sender IP
against the given domain-name, and reject fakes.   Forex, LKML rejected 
my attempts
to do this there.  gmail.com accepted my test msgs, but perhaps cuz they 
know me from
my pop access.


- patch also includes a tweak to prepare-kernel (chmod +w in patch_append)
I added it cuz I like to use lndir to clone source trees
(much smaller, and patch does the right thing - copies file, then 
modifies local copy.
only issue is that it preserves the readonly of the original (preventing 
inadvertent touches),
which breaks the append.)  Not sure its universally safe, but it works here.


Dont apply yet, not tested recently.

Qs

- should I run boxstatus just after latency tests or b4 and after (as 
currently) ?

- /proc/xenomai/* contents are dynamic (ie run by boxstatus) ?

- any bits of  boxinfo and boxstatus that should be shuffled around ?

- mail only works if -N andor -L are used.
probably unnecessary limitation. (im lazy)

- check NPTL availability (kinda overkill, since its absence when needed 
is already detected)


- anything else come to mind ?
