Since the kernel line transparent_hugepage=never only disables half of what I need (both, for annoying mongodb failing/logs), that I didn't persist through systemd startup script but now have: echo never | sudo tee /sys/kernel/mm/transparent_hugepage/enabled. That works in either systemctl boot script (when properly configured one in /etc/systemd/system) or ...

Just connecting the pins will not generate an interrupt. According to the document you referenced you need to write some data to pin 9 which has a short to pin 10 to generate the interrupt. Quote from your referenced document: Pin 9 is the most significant bit of the parallel data byte. If you write binary data to /dev/short0, you generate several ...

Why do people find it so hard to read kernel code? :P. http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/char/ppdev.c Seriously, it's common for devices to only be activated when they're needed - when userspace opens them. Example: If you look at ppdev.c, you'll see it presents an API where the parport is "claimed" (though not ...

In the linux kernel source code in sysrq.c at line 415, there is a struct defined, what should happen when a certain key is pressed. So you see, no command in a terminal is excuted, instead of this, hard coded functions in the kernel are called. So, as long as the kernel is not crashed, you can press those keys, doesn't matter which application is running in ...

As mentioned by @Lai , anything that is not distribution tuned may not work in subtle ways. But if you just want to play around without much thought, on 4.0 you might get away with: make defconfig which detects your architecture and uses for example arch/x86/configs/x86_64_defconfig as a basis. make help also shows other interesting default related ...

For me (Debian sid/stretch), the udev $id attribute is empty when I plug in my USB device. It is $kernel that contains the necessary string to pass to USBHID's unbind. Here are the udev rules that I'm using: SUBSYSTEM=="usb", ATTRS{idVendor}=="0000", ATTRS{idProduct}=="0000", MODE="0660", GROUP="plugdev" ATTRS{idVendor}=="0000", ATTRS{idProduct}=="0000", ...

The route or the ip utility get their information from a pseudo filesystem called procfs. It is normally mounted under /proc. There is a file called /proc/net/route, where you can see the kernel's IP routing table. You can print the routing table with cat instead, but the route utility formats the output human readable, because the IP adresses are stored in ...

Kernel 4.0.2 is available in Debian unstable. It can be installed on Jessie. If it doesn't work on your laptop, please report a bug (reportbug linux-4.0.0-1-686-pae if you're using the 32-bit version, or reportbug linux-4.0.0-1-amd64 if you're using the 64-bit version).

The kernel documentation describes bdl_pos_adj as follows (see ALSA-Configuration.txt and HD-Audio.txt): bdl_pos_adj - Specifies the DMA IRQ timing delay in samples. Passing -1 will make the driver to choose the appropriate value based on the controller chip. (sic). On Intel controllers, the default is 1 (which is ...

From User Mode Linux: skas mode: If you run ps, you will notice only four processes per UML rather than the dozens that you see in tt mode. They are The UML kernel thread, which runs in the separate kernel address space, executes kernel code, and does system call interception on UML processes The UML userspace thread, which runs all UML ...

it is relevant as unix question , you cannot maximise battery life ; but you can avoid spoil it e.g using xbacklight , not playing on line, charge it from 0 to 100% etc. Closing service on the kernel is not relevant at the battery life but at the security : it is for super-user trick/geek.

I will not add anything about importance or not of knowing that kernel version since the comments and the answer above is fully explained. But as an answer for your comment in the answer above What about graphics drivers (kernel build vs run environment) ? What you must care is the gcc version that the kernel was compiled with so that you have to use ...

I found the solution. I did not think it was important but I am a Digital Ocean's VPS. I followed this solution. I had to change the kernel version in the control panel and reboot through the control panel.

It's almost never important. If you're truly worried about the build system, you should consider the compiler, library and header versions before considering the kernel. It is up to the code itself as to whether it 'remembers' the kernel version. Some packages store a string representing the compiler version, as this is far more important. In fact the ...

You can download the relevant packages (which depend on your exact requirements) from Debian snapshots.

Only the vendors themselves know the real answer but here are some guesses. I would assume that it's simply because it would make the device more expensive. By requiring the OS to inject firmware at run time they get to avoid the need for non-volatile memory like ROM or Flash on the device. Secondarily, I would assume the vendors might also feel that the ...

When you mention 'contained in the device already' I am assuming you are referring to a method for device driver and firmware to allow a scenario of an operating system to query a device with a predetermined (possibly sanctioned API by the IEEE or other governing body) to then respond with a response of 'here is my device driver memory chip location address' ...

cman is new cluster project and redhat says: The Red Hat Cluster Suite cluster infrastructure provides the basic functions for a group of computers (called nodes or members) to work together as a cluster. Once a cluster is formed using the cluster infrastructure, you can use other Red Hat Cluster Suite components to suit your clustering needs (for ...

YES just checked the config on kernel 3.13 and UPROBES are present.

Are you compiling the module against the correct Kernel Version headers ? I faced this issue and then I installed headers of correct kernel version.

When you compiled are you included the elf and out file format? And compat32? When you compile ensure all "standard" options of the standard kernel are included best way is cd /usr/src/linux(must point to your new sources) zcat /proc/config.gz > .config make clean make oldconfig #answer only if sure and use a lot the ? make,make install etc etc Of ...

You could upgrade the kernel via elrepo. rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm (external link) yum install --enablerepo=elrepo-kernel kernel-ml You can also install the updated firmware and headers yum install --enablerepo=elrepo-kernel kernel-ml-{firmware,headers,devel} You'll probably need to remove the ...

Linux is a kernel. That is the main reason to call it a kernel. Ubuntu, Android and Chrome OS are fundamentally different operating systems. Applications for Ubuntu do not necessarily run on Android just like they do not necessarily run on Windows. For one simple reason: The operating system is different. Linux based operating systems also strongly differ ...

I don't know much about Raspbian. What I'd do is try modprobe algif_skcipher. If that doesn't work, look in /lib/modules for a file called algif_skcipher.ko. If there is one, try to find out what's wrong with modprobe. If there isn't one, then the distro elected not to compile that particular module and the only way forward would be do your own kernel ...
