Hi , I am trying to implement own system call in Linux. Kernel version I chose is 3.5.7
I am following the steps from Linux Kernel Development 3rd edition. I got two problems with the implementation. 1.while trying to modify the code in kernel , there is no entry.S file for Intel x86 32 bit architecture. (my be i am missing some thing.) 2.while I am compiling user application with gcc I am getting
Things have slightly changed in the newer kernel version you can refer the below links, https://bbs.archlinux.org/viewtopic.php?id=144772 http://blog.techveda.org/index.php/adding-system-calls-linux-kernel-3-5-x/ Regards, --Prabhakar Lad http://in.linkedin.com/pub/prabhakar-lad/19/92b/955
error: unknown type name ‘helloworld’
my application is as follows
#define __NR_helloworld 367 __syscall0(long, helloworld)
int main () { printf("The helloworld system call is\n"; helloworld(); return 0; }
I looked at Link [blog.163.com] which is given by Wanny but i could not find the solution,I could not locate syscall_table_32.s in my Linux source.
Please help me in identifying the entry.S file for Intel x86 32 bit architecture in 3.5.7 kernel version sources,where i can make an entry for my system call into system call table.
Help me in resolving error: unknown type name ‘helloworld’ in my application.
