Ubuntu :: Remove Mouse Feature In /proc/bus/input/devices
Jan 7, 2011ubuntu 10.10
I have a remote control (imon --> Harmony) that acts like a mouse. My goal is to remove that feature. Iam using lirc with Linux input layer (/dev/input/eventX) because Imon driver doesn't work at all. To get Linux input layer to work you need to choose the imon device.
Code:
cat /proc/bus/input/devices
Code:
I: Bus=0003 Vendor=15c2 Product=ffdc Version=0000
N: Name="iMON Remote (15c2:ffdc)"
P: Phys=usb-0000:00:12.1-2/input0

Fedora Installation :: An Error Occurred Mounting Device Proc As /proc: Mount Failed
Jul 6, 2010I've got the F13 LiveCD that I was able to boot and use using the "nomodeset" boot option. From the desktop I'm trying to perform an Install to Hard Drive. I've read the Install from LiveCD post regarding the creation of a /boot partition and a / root partition. I've tried creating them without the LVM group and with. But every time I appempt to install I get...
An error occurred mounting device proc as /proc: mount failed: (9, None). This is a fatal error and the install cannot continue.

Mar 30, 2010Red Hat Enterprise Linux Server release 5.4 (Tikanga) 2.6.18-164.11.1.el5xen (Xen release for virtualisation)
I'm trying to track down a problem with a utility that used to work and now hangs indefinitely. Since its hanging, I suspected a locking problem, and went to have a look for the process ids in /proc/locks; I get:
148: FLOCK ADVISORY WRITE 30279 ca:21:49153 0 EOF
148: -> FLOCK ADVISORY READ 30282 ca:21:49153 0 EOF
Now as near as I can tell this shouldn't be my problem, since the two ADVISORY locks - one READ and one WRITE - shouldn't conflict with one another. But I'd like to understand it all the same. I haven't been able to find any kind of definitive guide for the format of /proc/locks entries, but what I did find in the manuals specifically states:
"Each lock has its own line which starts with a unique number. "
Which is obviously not true; both of my lines start with the same number. Also, since most search engines don't seem to play nicely with symbols, I can't find any reference to what the "->" means.
General :: How To CPU Usage Of Process From / Proc?
Jul 15, 2011I am currently writing a JAVA script to monitor certain unix processes through JConsole. Upon having lots of trouble with runtime.exec, i decided to bypass the top/ps command call and just get the information straight from /proc/*pid*/whatever.Now i can pull back any information from any of the files I want, and the current way i determine the CPU usage of a process is as follows:
Add the UTime and STime of that process from /proc/pid/stat then divide my pidCpu by UTime + STime + NTime from /proc/stat, then multiply that by 100, should give me the % cpu usage a process is using, right?Theory being if I get the jiffies assigned to my process, I can divide that by the total jiffies the cpu assigns. However, my results seem to vary from the ones gathered from top and ps. What am I doing wrong?

General :: Unable To Open /proc Folder?
Sep 13, 2010i had some issue with the machine rebooting multiple times, What happens is that the machine boots up and suddenly crashes and then boots up cleanly. I was going through the log files during when this occurs. I came across /var/log/syslog which i guess logs messages before shutdown. It has following messages which i think are causing problem.
Could not open /proc/26694/stat: No such file or directory
Could not read the file /proc/26694/stat
Could not open /proc/31128/stat: No such file or directory
Could not read the file /proc/31128/stat
Does any one know what these messages are?
General :: USB And Hard Drive Listed In /proc But Not /dev
May 10, 2010I'm working in CentOS 5.4 with the default 2.6.18-164 kernel (which I will be editing but have reverted back to in order to solve this problem.)
Near the end of the init script I have thrown a /bin/sh to get into a busybox bash shell in order to test some scripts. Ive attached the init below.
While in this shell I can see my usb drive in /proc/bus/usb/devices and my hard drive in /proc/scsi/device_info however I cannot mount them as they are not in /dev.
I have scsi emulation set in the kernel. When I plug in a USB stick it finds the address but still no sign of it in /dev. There are other modules listed in /sys/module such as usbcore that dont show up in lsmod, is that possibly the problem?

Aug 4, 2011As I understand it, setting /proc/sys/vm/overcommit_memory to 1 is supposed to make sure malloc always succeeds, and set the OOM killer loose if there's an actual memory problem.
I'm wondering what happens when you've malloc'd so much memory that you've exhausted the address space for your process? Does it return NULL despite the overcommit_memory setting, or does your process get a signal? Or something else entirely?

General :: Find Which HT-cores Are Sharing A Physical Core From /proc/cpuinfo
Sep 2, 2011There is a computer with two "Xeon(R) CPU X5550 @ 2.67GHz" CPU. The Hyper-threading is enabled, so it looks like 16-core system, but really there is only 8 physical cores.
I know that when hyperthreading is enabled, each physical core is splitted into two virtual cores. I want to know, which pair of virtual cores shares a physical core and which are not. Or, how (in what order) will Linux enumerate HT-cores comparing to real cores. (enumerating is done for sched_setaffinity and taskset masks).
I have a dump of /proc/cpuinfo file from the system.
I think there are possible:
CPU0-CPU7 are not sharing phys. core. CPU8-CPU15 too. But sharing is in pairs CPU0+CPU8, CPU(i)+CPU(i+8) and so on. or CPU0+CPU1 are from single physical, CPU2+CPU3, CPU(2*i)+CPU(2*i+1). or exotic CPU0+CPU15 sharing, CPU1+CPU14 ... or random?
The hard moment in this case is that there are 2 physical dies of CPU (two sockets), and usual recommendation of using "physical id:" field can't help
The cpuinfo:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 26
model name : Intel(R) Xeon(R) CPU X5550 @ 2.67GHz

General :: Java Process Without Memory Detail In Proc File System?
May 13, 2010To get the kernel messages of new java process, i refer the details from /proc/<java pid>/stat and /proc/<java pid>/statm files. For some java processes, I didn't find any details in the /proc/<java pid>/statm file. It has only 7 number of 0s. But /proc/<java pid>/stat file has the details. And also this kind of process will have the life time of nearly 1 minute.
Kernel version using: Linux-2.6.18-8.1.8.el5 Is there any possibility of java process without the memory details in the /proc/<java pid>/statm file? If it is possible, how to know the memory related details of that processes?

I presume this is because ubuntu 10.10 does not mount USB device filesytem (usbfs) in /proc/bus/usb folder and i can't manually create this folder therefore making it impossible to mount usbfs manually into this folder.
Ubuntu :: Get IO Time From /proc/diskstats?
Oct 28, 2010I want to know how much time the computer is performing IO read/write during a time interval, so that i can compute the percentage of time spending on IO. I look at /proc/diskstats, and notice that there are these fields:
Field 1 -- # of reads issued
Field 2 -- # of reads merged, field 6 -- # of writes merged
Field 3 -- # of sectors read
Field 4 -- # of milliseconds spent reading
[Code].....
How can this happen? I thought the maximum value of the read and write time should not exceed the total time. Am I doing something wrong? Are there any other methods to get the disk IO time?

Networking :: Record Tx/Rx Bw In A Program - Without Using Tools From /proc/net/
Feb 22, 2011I need to record Tx/Rx bw in my c program at defined intervals. I am aware that there a bunch of available tools but I need a minimal version with only Tx/Rx bw with no other details. I have tried the tool bwm-ng which mostly serves my purpose but either it runs continuously in the console or saves result in html file. It does not have any options to save the result in txt file which could have been easy to parse.
Is there any other simple way to record Tx/Rx bw in a program?(without using tools from /proc/net/ or any) I am using Mandriva Linux 2.6.31.5.
Programming :: Way To Make Proc Filesystem Writable?
