Hi,
I just got into kernel development and currently doing some patching
of the usb divers for coding style adaptions and so on.
My current workflow is:
- get latest torvalds master
- merge local master with fast forward to torvalds/master
- create new branch, say "usb-core-foobar-cleanup"
- pat
Hi Ulka,
You need to add edit two more files.
Add the following in file "arch/x86/include/generated/uapi/asm/unistd_32.h":
#define __NR_helloworld 349
Add the following in "include/linux/syscalls.h" :
asmlinkage long sys_helloworld(void);

Ok. So this won't contain "files" but rat
Hi All,
I have Implemented sample system call on tree 3.4.6
Following are the steps i did -
- >I created directory hello in kernel sources base directory i.e
/usr/src/kernels/linux3.4.6/hello
-> I have created hello.c file in which i added system call definition
#include
asmlinkage long sys_hell
Which is the best ARM Quad board ( e.g., ARM Cortex-A15 MPCore)
available in the market for linux kernel development. Board must have
hardware virtualization support.

Hi All,
I have a newbie question on disk/filesystem caches, so please bear with me!
:)
* Is disk cache the same as filesystem cache? Or there's nothing like a
filesysten cache and all disk I/O, irrespective of what FS is being
accessed, is cached in a "disk cache"?
* Is this caching done at the
