Re: Booting Custom Kernel

Dear Arindam, What I understand is, your system has two Ubuntu 12.04 installations side by side. Are you using any one of those two to compile the 2.6 kernel? If so, then executing *sudo make install* will copy the kernel vmlinux, initrd and System map files to /boot directory and trigger an

Linux Kernel compiles all the sources for a single a syscall

Hi, I have compiled 3.4 kernel. Following the tutorial http://blog.techveda.org/adding-system-calls-linux-kernel-3-5-x/, I have updated syscall_64.tbl and triggered a 'make'. Now it has started elaborate compilation process, e.g. /fs/*.o sources. Shouldn't make only compile the changed files?

Invoking a system using syscall()

Hi, I want to invoke getpid() system call using syscall. Here's the code snippet below. But, I can't find anything in dmesg|tail output. #include sys/types.h int main() { pid_tret = syscall(20); return 0; } ___ Kernelnewbies mailing list

Adding a syscall to specific kernel version

Hi, I am trying to add a new syscall to kernel 3.4. So far I have tried at least four different tutorials from Internet. To my utter frustration, whatever source files they have referred in the tutorials, at least one of those is missing in all the cases. Why isn't there a consistent interface

Hi. I tried building Linux Kernel 3.4 from the source on Ubuntu 10.04 (Linux LAPTOP 2.6.32-21-generic #32-Ubuntu), gcc 4.4.3 on Intel processor. Here's the output: make[1]: Nothing to be done for `all'. make[1]: Nothing to be done for `relocs'. CHK include/linux/version.h CHK

How to test a syscall prior to compiling the kernel

Hi, While adding a syscall, how do I test the syscall code itself? If I simply try to compile the C file individually, will the compiler be able find the includes? ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org

get_user() and put_user() missing in syscall list

Re: How to call syscalls - SYSCALL or 0x80 interrupt

Is in incorrect because the execve() call in the code is to the libc stub but not the actual syscall itself? On 3 June 2014 10:19, Greg KH g...@kroah.com wrote: On Tue, Jun 03, 2014 at 09:45:33AM +0530, Dipanjan Das wrote: Hi, I came across this discussion in StackExchange. Does anyone
