|how do programs communicate - micro kernel monolithic kernel exo kernel|
| by Shadowknight in Web Design|
how do programs communicate with the micro kernel/monolithic kernel/exo
I have read many books that show as in the
picture, that monolithic kernels communicates with the program through the
system call table/filesystem layer.
But how do micro kernels
and exo kernel communicate with the program?
does the base of
the micro kernel talk dire
|How to safely backport specific linux kernel commits to an older kernel using git|
| by Andrew Mattie in Operating Systems|
I'm currently on a stable 2.6.32 kernel. But I need certain fixes on
2.6.33 branch to be incorporated into this 2.6.32 kernel so that I can
create a custom kernel for testing purposes. I can't apply the said fixes
directly to the 2.6.32 source because they seem to have dependencies on
Is there any safe way to incorporate only the
fixes (and all their dependencies) I nee

|How to determine whether a linux kernel is 32bit or 64bit from a running kernel module|
| by Guilherme Costa in Programming Languages|
Here is the deal. I want to write a kernel module which depends on the
kernel type (32 or 64 bit).
There are some lines of code which I want
to be included in the module if and only if the kernel is 32 bit and some
lines of code which should be included iff kernel is 64 bit.
there anything like #if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,26) for
this case ?
|Is there a module in Linux Kernel for copying data directly between two character devices in kernel space?|
| by amosk in Operating Systems|
We need to multiplex data from one (USB) serial device to multiple
independent serial devices.
What I've found, is the module fanout, this
addresses the multiplexing part of my problem.
Now I search for
an easy, probably ready to use, way to copy the data from the serial USB
device to the fanout device directly in the kernel space.

|Linux Kernel - Where in the kernel are blocks of data physically written to specific disk partitions?|
| by Hai Nguyen in Operating Systems|
I'm modifying the Linux kernel and am trying to find where in the kernel
source blocks of data are physically written to disk partitions such as
ubd0. Where does this occur in kernel source? The actual physical write
call? I cannot find this. Thanks!
Edit: The end goal is a list
of block numbers that have been written to a few different partitions. As
data is physically written to t
|How to automate linux kernel module compilation when installing a new kernel?|
| by OutOfBrain in Operating Systems|
I am writing a Linux kernel module. It is released with all the source
files (although the license is proprietary) to be compiled against the
running kernel. When installing my module (distributed as a
.deb package) it is compiled and installed automatically. This
The issue is that during the regular upgrade process of
the whole Linux systems, newer version of th

Does it poison my library with

|Linux/Kernel: How to select Videobuf2 framework as kernel module?|
| by jrok96 in Operating Systems|
I'd like to select videobuf2 modules as kernel modules. I do "make
menuconfig" but I don't find anything.
I'd like to have .ko
files in order to load them because I'm programming a driver based on VIVI
which uses them.
I guess, I'll have to recompile the kernel
entirely, but is it possible just to recompile/rebuild the modules
