Topic - What Is Linux Kernel And How To Upgrade To Linux Stable Kernel 3.18.1

What Is Linux Kernel?

Those who don't know what is the Linux Kernel they should know it because Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.

Latest Stable Linux Kernel Version 3.18.1
It's been a quiet week, and the patch from rc7 is tiny, so 3.18 is out.
I'd love to say that we've figured out the problem that plagues 3.17 for a couple of people, but we haven't. At the same time, there's absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn't make sense. Especially since
that would just have then held things up entirely over the holiday break.
So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that "Ahaa" moment) over the next week. But in solidarity with Dave (and to make my life easier too let's try to avoid introducing any _new_ nasty issues, ok?]

Preempt_rt Install Over Ubuntu 14.04

Hi everyone (i hope this is the right section)

Im trying to install the RT patch preempt_rt 3.18.9 im running Ubuntu 14.04 with kernel v 3.16

i installed the rt patch "patch-3.18.9-rt5.patch" and also a new kernel "3.18.9" i patched the patch file with

patch -p1 < patch-3.18.9.patch

but there is somthing i don't know about linking folders of old kernel and new kernel, i searched about it and found

rm -rf linux && ln -s /usr/src/linux-3.18.9 linux && cd /usr/src/linux

then

make oldconfig

then

make menuconfig

i selected Full preemptive kernel then

make

then this error

cc1: some warnings being treated as errors make[2]: * [kernel/locking/locktorture.o] Error 1 make[1]: * [kernel/locking] Error 2 make: *** [kernel] Error 2

So..... Any help?? can someone walk me through this

or any other real time patch, Thanx.. plzzzzzz

Kernel Updates -LInux Mint 17.1 W/Cinnamon

I'm new to Linux and have a question regarding the updating of Linux Kernels.

Should I wait until a kernel update is offered through the update manager, or should I go and get an updated kernel from the update manager/view/linux kernels?

HowTo: Compile/Install Linux Kernel 3.19 On Debian Jessie

Would anyone be willing to share their knowledge on: How to compile and install Linux Kernel 3.19 in Debian jessie?

So the new kernel is out and I've been patiently waiting for its release for the support of Microsoft Surface peripherals. I recently switched over to Debian because I'm not fond of some of the moves Ubuntu is making. So thats the short story, and fundamentally unimportant to the question.

Considering my lack of experience with Linux, or should I say others extensive experience, please be as detailed as you care to be. I did end up finding instructions containing 4 or so lines with 3 or so words in each line, buried in some website, but the information wasn't sufficient for me to follow. Needless to say those instructions were for someone who didn't need the specific terminal commands which I certainly do.

Thank You.

Confusing Tutorials: Which One To Follow?

Hi everyone,
I'm planing to join the development team of Linux kernel. As the first step, I started to clone git repo of the linux-next that I found two contradictory tutorials:

https://www.kernel.org/doc/man-pages/linux-next.html

https://github.com/gregkh/kernel-tut...rnel_patch.txt

Which one should I follow?

Thanks.

Something's Wrong With GRUB

Ubuntu 12.04

I installed updates, which included a new kernel. I went to remove one of the older kernels and got:

Ubuntu Will Not Dual Boot Beside Windows 7--error Codes

I have windows 7 laptop, Dell. I downloaded the newest edition of Ubuntu (Twice)to see if it would install and dual boot beside Windows 7. Unsucessful on several attempts. Once I reboot the computer it will give ma a choice of 7 or Ubuntu. I decide on Ubuntu it starts to boot into Ubuntu than a black screen with all types of Kernel error codes that i'm unfamilur with. one is---(1.292618) kernel panic-not syncing: no working init found.

Try passing init option to Kernel (see Linux Documentation/init.txt for guidance..

I am not sure what all this means any help would be appreactiated...

Kernel V4

Hi guys prob a silly question...
i only just read now that linux kernel v4 was released about 11 days ago...can any distros upgrade there kernel to 4 or only specific ones?

Is there really a huge benefit in doing so?

should i just lookup the information in the distros web site?

Changing McBSP Registers In Embedded Linux Kernel On Beagleboard XM

Hi everybody,

I hope this is the rate place for this question on which gives me a realy hard time.
I have a Beagleboard xM running Ubuntu (installed via Matlab Simulink Support Package), which is connected to a CS42448 audiocodecboard. To communicate with that codec I will have to change the McBSP-Registers on the DM3730 Processor, which is of the OMAP3 Family. (If it helps: McBSP is nothing else then the I2S-Version of Texas Instruments, which is a bus for serial audio data)

To do so I think I will have to change the kernel, but how can I find the right files and how can I change the kernel? The Kernel I'm running is 3.2.0-23-omap
Furthermore I could find in 'usr/src/linux-headers-3.2.0-23/sound/soc/omap/' a makefile and the Kconfig which includes the following (and much more)

-config OMAP_MCBSP
tristate
depends on ARCH_OMAP

config SND_OMAP_SOC_MCBSP
tristate
select OMAP_MCBSP

I don't want to post to much and I can't really tell what information is relevant and what not. I'm quite new to linux and would be really really happy if you guys could give a few tipps and tricks or probably a ruff list of things I have to do, to change these Register to what I want them to be.

Thank you very much allready!

Regards,

Lenni

What Is Context Switching

I'm currently reading Brian Wards book: How Linux Works: What Every Superuser Should Know 2nd edition and I'm confused about step 3 in the context of the other steps:
1. The CPU (the actual hardware) interrupts the current process based on an internal timer, switches into kernel mode, and hands control back to the kernel.

2. The kernel records the current state of the CPU and memory, which will be essential to resuming the process that was just interrupted.

3. The kernel performs any tasks that might have come up during the preceding time slice (such as collecting data from input and output, or I/O, operations).

4. The kernel is now ready to let another process run. The kernel analyzes the list of processes that are ready to run and chooses one.

5. The kernel prepares the memory for this new process, and then prepares the CPU.

6. The kernel tells the CPU how long the time slice for the new process will last.

7. The kernel switches the CPU into user mode and hands control of the CPU to the process.

What does he mean preceding time slice as surely the tasks have been completed during the time slice in steps 1-2?

Kdebug PPPd Option Is Not Logging Into /etc/syslog To Log The Kernel Level Raw PPP

Hello

I am trying to log the Kernel level PPPd raw PPP messages (version 2.4.2) using Linux kernel 2.6.x to the /etc/syslog or /var/log/messages but the logging is not enabled for some reason.

I pass the kdebug 7 or kdebug 31 to the PPPd using /etc/ppp/options but the Kernel level debug logs are not shown in /proc/kmsg or using klogd or syslogd.

Can anyone please help me to fix this. What might be the problem?

Please reply..

Thanks,
Rakesh
