Uh, I just googled this thread and wanted to contribute, I hope it's not considered necroing, since the last reply was quite some time ago, and I'm not even using any SuSE..
This is my Lemote YeeLoong 8089B that I bought in China. I had the chance to even talk to some people who worked on the chinese Loongson-2f processor design at the University of Technology in Beijing (that's the CPU in the YeeLoong), it's running Debian Wheezy/sid modified to work on the Loongson's slighty changed MIPSEL arch with PMON2000 firmware:
And here a hacked open Buffalo TeraStation III NAS running some custom Linux with Busybox, the CPU is an ARM926 (v5 arch level), optimized by Marvell, effectively changing the processor pipeline to do out-of-order execution:
hi,
we all know /proc is about the information of active process,
I have just read an artical which said you can use /proc/cpuinfo,
/proc/net./proc/meminfo etc. to know about some hardware
information .But I want to know how to use with command line? (1 Reply)
I did a search on this, but didn't find exactly the answer I'm looking for. What exactly is the proc directory for? Showing processes spawned by users? I ask because I have some very large files in that directory by multiple users and its affecting my disk usage. Can you limit how many... (2 Replies)
Hi,
What are the various way's to fix /proc folder in redhat linux 7.2 and how to verify /proc folder is proper or croupted?

hi all !
Please help me
When I select data from oracle with proc * C prog.
I count the number of rows
For example the total rows is 1000000
but the number of result return is a limit number 5000 for ex
So How can I know this limit (5 Replies)
Perhaps this is a very dummy question but sorry I don't know other place to do it. We just buy a new cluster of Xeon machines but there is something I don't understand and perhaps someone can help me.
The more /proc/cpuinfo produces the following output (just part of it).

Hi,
I am trying to calculate the CPU Usage by getting the difference between the idle time reported by /proc/stat at 2 different intervals. Now the 4th entry in the first line of /proc/stat will give me the 'idle time'. But I also came across /proc/uptime that gives me 2 entries : 1st one as the... (0 Replies)
So, I'm looking over /proc/cpuinfo and have a question... I've read that "siblings" refers to hyperthreading, but that seems odd considering the contents of cpuinfo. Here's a part:

physical id : 0
siblings : 4

If you are adding the kernel module without any module parameter passing, it should print out following information to info1 file so that user can make read access to info1 file (via, for example, cat /proc/info1):
• Processor type
• Kernel version
• Total number of the processes currently... (1 Reply)
Hi,
I wanted to understand what exactly /proc/cpuinfo shows?
We have a machine with following specification...
(2x) Intel Xeon 6-core processors
So, ideally it shouls have 12processors, but the output on /proc/cpuinfo shows 24 processors.
Can someone please explain how this is... (3 Replies)

mpstat
MPSTAT(1) Linux User's Manual MPSTAT(1)NAME
mpstat - Report processors related statistics.
SYNOPSIS
mpstat [ -A ] [ -I { SUM | CPU | SCPU | ALL } ] [ -u ] [ -P { cpu [,...] | ON | ALL } ] [ -V ] [ interval [ count ] ]
DESCRIPTION
The mpstat command writes to standard output activities for each available processor, processor 0 being the first one. Global average
activities among all processors are also reported. The mpstat command can be used both on SMP and UP machines, but in the latter, only
global average activities will be printed. If no activity has been selected, then the default report is the CPU utilization report.
The interval parameter specifies the amount of time in seconds between each report. A value of 0 (or no parameters at all) indicates that
processors statistics are to be reported for the time since system startup (boot). The count parameter can be specified in conjunction
with the interval parameter if this one is not set to zero. The value of count determines the number of reports generated at interval sec-
onds apart. If the interval parameter is specified without the count parameter, the mpstat command generates reports continuously.
OPTIONS -A This option is equivalent to specifying -I ALL -u -P ALL
-I { SUM | CPU | SCPU | ALL }
Report interrupts statistics.
With the SUM keyword, the mpstat command reports the total number of interrupts per processor. The following values are displayed:
CPU
Processor number. The keyword all indicates that statistics are calculated as averages among all processors.
intr/s
Show the total number of interrupts received per second by the CPU or CPUs.
With the CPU keyword, the number of each individual interrupt received per second by the CPU or CPUs is displayed.
With the SCPU keyword, the number of each individual software interrupt received per second by the CPU or CPUs is displayed. This
option works only with kernels 2.6.31 and later.
The ALL keyword is equivalent to specifying all the keywords above and therefore all the interrupts statistics are displayed.
-P { cpu [,...] | ON | ALL }
Indicate the processor number for which statistics are to be reported. cpu is the processor number. Note that processor 0 is the
first processor. The ON keyword indicates that statistics are to be reported for every online processor, whereas the ALL keyword
indicates that statistics are to be reported for all processors.
-u Report CPU utilization. The following values are displayed:
CPU
Processor number. The keyword all indicates that statistics are calculated as averages among all processors.
%usr
Show the percentage of CPU utilization that occurred while executing at the user level (application).
%nice
Show the percentage of CPU utilization that occurred while executing at the user level with nice priority.
%sys
Show the percentage of CPU utilization that occurred while executing at the system level (kernel). Note that this does not
include time spent servicing hardware and software interrupts.
%iowait
Show the percentage of time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request.
%irq
Show the percentage of time spent by the CPU or CPUs to service hardware interrupts.
%soft
Show the percentage of time spent by the CPU or CPUs to service software interrupts.
%steal
Show the percentage of time spent in involuntary wait by the virtual CPU or CPUs while the hypervisor was servicing another
virtual processor.
%guest
Show the percentage of time spent by the CPU or CPUs to run a virtual processor.
%idle
Show the percentage of time that the CPU or CPUs were idle and the system did not have an outstanding disk I/O request.
Note: On SMP machines a processor that does not have any activity at all is a disabled (offline) processor.
-V Print version number then exit.
ENVIRONMENT
The mpstat command takes into account the following environment variable:
S_TIME_FORMAT
If this variable exists and its value is ISO then the current locale will be ignored when printing the date in the report header.
The mpstat command will use the ISO 8601 format (YYYY-MM-DD) instead.
EXAMPLES
mpstat 2 5
Display five reports of global statistics among all processors at two second intervals.
mpstat -P ALL 2 5
Display five reports of statistics for all processors at two second intervals.
BUGS
/proc filesystem must be mounted for the mpstat command to work.
Only a few activities are given by the Linux kernel for each processor.
FILES
/proc contains various files with system statistics.
