Wow, a zSeries. I have only seen one such mainframe myself briefly when I was allowed to visit one of the three high security server centers of the Banks of my country (they are located in our capital and serve the whole infrastructure of the country, all national banks included).
I was impressed by the looks of the zSeries mainframe alone!
And now on topic, this is cat /compat/linux/proc/cpuinfo, and shows what linux.ko, the kernel driver of FreeBSDs Linux compatibility layer lets through to the linprocfs subsystem (this is actually PC-BSD 9.2 UNIX, but it's using FreeBSDs kernel):

As you can see, the bogomips is just trash, as they're not computed on bootup. So they just copy the clock rate and use that number. Plus, some other information is obviously missing, like cache alignment, address spaces etc.
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 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.

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:

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)

est
EST(4) BSD Kernel Interfaces Manual EST(4)NAME
est -- Enhanced Speedstep Technology
SYNOPSIS
To compile this capability into your kernel place the following line in your kernel configuration file:
device cpufreq
DESCRIPTION
The est interface provides support for the Intel Enhanced Speedstep Technology.
Note that est capabilities are automatically loaded by the cpufreq(4) driver.
LOADER TUNABLES
The est interface is intended to allow cpufreq(4) to access and implement Intel Enhanced SpeedStep Technology via acpi(4) and the acpi_perf
interface accessors. If the default settings are not optimal, the following sysctls can be used to modify or monitor est behavior.
hw.est.msr_info
Attempt to infer information from direct probing of the msr. Should only be used in diagnostic cases. (default 0)
hw.est.strict
Validate frequency requested is accepted by the cpu when set. It appears that this will only work on single core cpus. (default 0)
SYSCTL VARIABLES
The following sysctl(8) values are available
dev.est.%d.desc
Description of support, almost always Enhanced SpeedStep Frequency Control.
dev.est.0.%desc: Enhanced SpeedStep Frequency Control
dev.est.%d.driver
Driver in use, always est.
dev.est.0.%driver: est
dev.est.%d.parent
dev.est.0.%parent: cpu0
The cpu that is exposing these frequencies. For example cpu0.
dev.est.%d.freq_settings.
The valid frequencies that are allowed by this CPU and their step values.
dev.est.0.freq_settings: 2201/45000 2200/45000 2000/39581 1900/37387
1800/34806 1700/32703 1600/30227 1500/28212 1400/25828 1300/23900 1200/21613 1100/19775 1000/17582 900/15437 800/13723
DIAGNOSTICS
est%d: <Enhanced SpeedStep Frequency Control> on cpu%d
Indicates normal startup of this interface.
est: CPU supports Enhanced Speedstep, but is not recognized.
est: cpu_vendor GenuineIntel, msr 471c471c0600471c
device_attach: est%d attach returned 6
Indicates all attempts to attach to this interface have failed. This usually indicates an improper BIOS setting restricting O/S control of
the CPU speeds. Consult your BIOS documentation for more details.
COMPATIBILITY
est is only found on supported Intel CPUs.
