Request (small) porting help for linuxinfo

[Helge Kreutzmann]

Hello,
I maintain the small utility linuxinfo which displays a brief summary
of the cpu/system. I am unsure about the s390 port and would like to
improve / update it. (Also if you have other machines and it does
not work there, please let me know as well!) Since I have no access
to such a machine, I would be glad to know of failures (in PM or via
reportbug(1)) of it. The requested test (in unstable or testing, if
possible) is quite simple:

a) apt-get install linuxinfo

b) linuxinfo
If the output is incorrect, I need

c) cat /proc/cpuinfo
ls -l /proc/kcore
ls -l /proc/meminfo

(or use reportbug, which includes these infos automatically)

along with the output of linuxinfo (any maybe the number of cpus you
have).

Thanks for all the input!

Greetings

Helge

c) cat /proc/cpuinfo
ls -l /proc/kcore
ls -l /proc/meminfo

cat /proc/meminfo, obviously.

Hi,

I am unsure about the s390 port and would like to improve / update it.

I run S/390 on the hercules emulator and have given it a try there.
The basic info should be the same to a real machine though.

b) linuxinfo
If the output is incorrect, I need

$ linuxinfo
Linux mordor 2.4.27-2-s390 #1 SMP Fri Aug 26 19:19:03 UTC 2005
One IBM/S390 MHz processor, 248.21 total bogomips, 0M RAM
System library 2.3.6

CPU frequency missing? No idea how to get that though.
RAM looks bad.

c) cat /proc/cpuinfo

vendor_id : IBM/S390
# processors : 1
bogomips per cpu: 248.21
processor 0: version = FD, identification = 002623, machine = 3090

ls -l /proc/kcore

-r-------- 1 root root 67112960 Mar 8 18:22 /proc/kcore

ls -l /proc/meminfo

-r--r--r-- 1 root root 0 Mar 8 18:23 /proc/meminfo

Hmm. cat is probably more useful:
/proc/meminfo:
total: used: free: shared: buffers: cached:
Mem: 62824448 58621952 4202496 0 1449984 12615680

I have set up the emulator with 1 CPU.

Did you call linuxinfo and the ls as ordinary user? I wonder, because
the size looks ok.

Do you have moment to spare and can I send you a patch to try? As I
am not a Debian developer, I do not have access to a s390 machine so
I cannot try myself.

I would like to understand why the harmless stat call fails for
(appearingly all) s390 machines:

if (stat("/proc/kcore", &st_buf) < 0)
{
memory = 0;
}

(or if the error is elsewhere ...).

Greetings

Yes to both.

Sure. I'm fairly busy over the weekend, so a reply to a test request may
have to wait until after that.

No problem, I don't expect Etch to be ready next week either (and I'll
be offline 'till Tuesday as well) :-))

When you have time, can you do the following:

apt-get source linuxinfo
cd linuxinfo-1.1.8
fakeroot make -f debian/rules patch

Then please replace linuxinfo_common.c with the version I attached and
run
fakeroot make -f debian/rules build
and send me the output of
./linuxinfo

Hopefully I see than where the memory size gets set to 0 ...

Thanks!

With the (privately sent) patched version, I get:

Thanks. Understood and fixed. I sent a new version (-16) to my sponsor
which fixes the memory reporting on s390.

Thanks to all for testing!
