OpenSUSE Hardware :: Missing I2c-core.ko In 11.3 X86-64 (kernel 2.6.36)?
Nov 13, 2010
I was bugging around with my nvidia driver and while reading README.txt I saw the following:
"NVIDIA has noted that in some distibutions, i2c support is enabled. However, the Linux kernel module i2c-core.o (2.4) or i2c-core.ko (2.6), which provides the export infrastructure, was not shipped. In this case, you will need to build the i2c support module. For directions on how to build and install your kernel's i2c support, refer to your distribution's documentation for configuring, building, and installing the kernel and associated modules."
So I checked if I have i2c-core.ko and I saw that it is not present as a built module, but only as a source code. So, my question is, is there any reason that the module is not shipped with openSUSE 11.3 x86_64 (I use the kernel HEAD repository)? Actually, does it make sense to use this module if I want to monitor the temperature of my GPU with sensors? How can I compile only that module and install it?

I have a command line OCR program called OCR Shop XTR (Vividata corp) that I am using on a system with a 6-core AMD chip. I changed the bios so that the 6-cores were activated, but htop shows me that while the program is running, I am only getting activity on one core (the program maxes out the one core with consistent usage between 97% and 100%).
I have read that many programs are not written to take advantage of multiple core cpu's. However, I am just hoping that there is some way to get this program to take advantage of the extra cores. Does anyone know of a way to invoke programs from the command line which would spread the workload out among additional cores?
Here is the output of uname -a:Linux linux 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 i686 athlon i386 GNU/LinuxAnd here is the output for one of the cores from cat /proc/cpuinfo:processor : 5
vendor_id : AuthenticAMD
cpu family : 16
model : 10
model name : AMD Phenom(tm) II X6 1100T Processor

I'm running Linux on an Intel Core 2 Duo processor. When I apply power to my computer, it boots into one core but appears to leave the other one idle. On the screen, it prints:
....
SMP: Allowing 2 CPUs, 1 hotplug CPUs
.....
I can confirm that only 1 CPU is active by logging in and examining /proc/interrupts and /proc/cpuinfo. After issuing a "reboot" command, the screen shows:
...
SMP: Allowing 2 CPUs, 0 hotplug CPUs
...
So, when I do a cold boot, I one get 1 CPU. When I do a warm boot, I get both CPUs. This is a problem for me because I'm running Linux on an embedded board and I need both CPUs to be running.
I've played around with BIOS settings, the boot string, kernel configuration, and CPU hot plugging. I can't seem to find a way to get both processors running without booting the system twice.
I thought that the CPU hot plugging path showed some promise but I can't seem to get that feature working on my system. The first issue is that the Linux documentation doesn't seem to match with what I'm seeing. It states that you should be able to go into /sys/devices/system/cpu/cpuX/ and write a zero or a one to the file labeled 'online' to disable it or enable it. When I go to /sys/devices/system/cpu I only see a directory for cpu0. There isn't a directory for cpu1.
After a reboot, I do see two directories int /sys/devices/system/cpu (cpu0 and cpu1). At this point, it won't let me 'offline' the second processor. The echo command gives me an error. (By the Way: the 'online' file in each cpuX directory has read only permissions.) This error occurs after I've changed the permissions on the file to read/write.
I confirmed that the following parameters are set in my .config file: CONFIG_HOTPLUG, CONFIG_HOTPLUG_CPU, CONFIG_SMP, CONFIG_SUSPEND_SMP
I've done searches on google until my eyes popped out and can't find much information. I see others have had similar problems but they all seem to link back to ACPI in BIOS. I've already played with all of those settings and I didn't see any effect. One reason I don't think it's a BIOS problem is because a warm boot (reboot) seems to 'fix' it.
I've tried different kernels, different distributions, and different computers. I see similar behavior in all configurations. I feel like I'm missing something fundamental.

opensuse v11.2linux 2.6.31.12-0.1-desktop x86_64The kernel symbol file is still at 2.6.31.3. Apparently the symbol file did not get updated with the rest of the kernel development files. At least one program does not build because of that

I've read that you can use specialized kernels for your hardware, and I was wondering if there's a kernel I can use for my Intel Core 2 duo. I read in a previous post about using a "smp" variant, but kinda wanted some confirmation. Here's CPU info:
Code:
processor : 0
vendor_id : GenuineIntel

My system has Intel Xeon 4-core cpu(hyperthreading 8-core) and run 64-bit linux. I want to allocate one core for general process(kernel process & other processes). And then, I want to allocate the rest of core for the specific multi-thread program.
Q1: I know that I can pthread_setaffinity() for user-mode thread and mpstat for monitoring. So, how can I allocate a core for kernel process and monitor it?
Q2: How can I restrict use of the cores for the multi-thread program? I don't want kernel process to use the cores for the multi-thread program.

I've been trying to install nvidia drivers yesterday, so I went to runlevel 3, ran the .bin installer and it came up with error: missing kernel-devel and kernel-source.
So I go yum install kernel-devel, it does, but it doesnt find anything like kernel-source.
How do I fix this issue? I have Fedora 12, and I ran drivers from:[URL]..

I just installed the lenny (amd64) on my new core i7 870 computer (with netinst), but the kernel failure message appeared everytime I booted into gnome. I don't know how to solve this problem. Sorry I don't have much experience with installing linux, though I have been its user for a few years.

I am using Opensuse 11.2 on an HP Pavilion laptop. The internal wireless (Broadcom device) quit on me - It is no longer detected at boot so I assume it is dead. No problem since I have a D_Link USB adaptor (DWL-G132). To get it working however I need ndiswrapper. I then installed ndiswrapper 1.55 and the user interface supplied with Opensuse. Problem1- The interface says "The program 'kernel-headers' is missing on your system".
I have checked with Yast and the kernel-headers are installed. Problem2- I have downloaded ndiswrapper 1.55 from Sourceforge.net to attempt the traditional installation method. The 'make' command returns the following message: "Cannot find kernel version in /lib/modules/2.6.31.8-0.1-desktop/build, is it configured?."

I have now installed Wheezy on two different hard drives and in each case it seems only one CPU of my dual core CPU computer is recognized. System Monitor, Gkrellm and lscpu show just one when prior to the new install the old Wheezy showed both CPU's. I have put the hard drive into two other computers with dual core CPU's and all show just one CPU.
Interestingly System Profiler and Benchmark (hardinfo?) > Devices > Processors now show a large amount of processor infomation when with the old Wheezy I would only see both CPU's listed and nothing else.

I've a Compaq CQ61 laptop, and i noticed that one of the cores is always at 100%.
I didn't check the duration of the battery but surely it will "eat" my battery in a hurry

I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.

Assume someone bind a particular process to a particular CPU core(In multi core machine) by using sched_setaffinity() like functions. Then how we can get that process running core id and CPU core utilisation of that process on that running CPU core(Pragmatically or by a Linux command)?.

At linux-kvm.org it is stated: "KVM ... consists of a loadable kernel module, kvm.ko that provides the core virtualization infrastructure" and yet there's no mention of Xen, which runs as the hypervisor with KVM. The site seems to be implying the module is the hypervisor. My question to you is: What is the relationship between KVM and Xen on a server that is "running KVM"?

I have created a virtual machine of a system running Fedora Core 4 and I need to upgrade it to Fedora Core 10. Based on what I have read, it iis possible so I started theupgrade process. I get an error message saying that /dev/hda6 (my root paritition does not exist) even though it does.
Does the installer need to read a label from /etc/fstab? I executed tune2fs -L / /dev/hda6 amd ,and added LABEL=/ for the corresponding entry for fstab. but the FEDORA CORE 10 is still giving the same problems for the installation process. Should I upgrade to an intermediate verson like Fedora Core 7 first?

I've a program that launches new processes, and wait for them to die before it exits. So, for example, my program is a process, and it launches 3 more processes, and when the 3 child processes end, it will exit.
As you see, at end of the example, the program used a total number of 4 processes.
1 - Now, I'm running this program in a CPU with 4 cores. This means that the program used each core for each process?
2 - How can I know which core the program used?

default in openSUSE 11.2 we have installed kernel-desktop. This kernel is optimized for the desktop.
What is the name of kernel optimized for server machine? In my case Firebird database + Apache + PHP?

I own an Athlon II X4, with 4 physical cores, and opensuse 11.4 x86_64 is only recognizing 1 of them. Although, when i disable ACPI from the BIOS, i get all 4 cores showing on cpuinfo.
Code:
Linux version 2.6.38.4-2-desktop (geeko@buildhost) (gcc version 4.5.1 20101208 [gcc-4_5-branch revision 167585] (SUSE Linux) ) #1 SMP PREEMPT 2011-04-26 17:30:28 +0200

It's known that with previous iterations, up to and including 11.2, with certain motherboards ( I can only speak for Asus/Abit ) a quad ( or duo ) core cpu can only be installed with acpi-off or similar options; this leads to only one core running in OpenSUSE, although the board itself declares 4 cores run.And this seems to mean that various other unimportant ( for a desktop ) acpi functions are affected, including the os system clock.
Typing top or cat /proc/cpuinfo always shows only one core, and although the computer is fine, it seems a pointless state of affairs. Googling shows various suggestions, including removing acpi=off or noapic in the boot options and substituting pci=nommconf, or changing the kernel to an SMP kernel ( which is probably out-of-date as advice now ); still, I can live with it in 11.2: I just wondered if 11.3 addresses this installation problem. Or will any future editions address it ?Whilst one can live with it, the initial impossibility of installing ( with no clue as to why it shan't install ) must have put off a deal of people from even going forward with OpenSUSE ( or any similarly affected distro ).
