[Linux-ia64] sys_epoll patch for ia64-linux

[GV <gv_kovai@yahoo.com>]

Hello All,

I am new to this list. Have a sys_epoll patched 2.4.20
kernel. sys_epoll
patch adds the following 3 system calls

epoll_create()
epoll_ctl()
epoll_wait().

As this patch actually targets i386, modified the two
files for ia64 as
follows for the kernel compilation.

/usr/src/linux-2.4.20.se1/include/asm-ia64/unistd.h
/* Added by GV - sys_epoll support */
#define __NR_epoll_create               1280
#define __NR_epoll_ctl                  1281
#define __NR_epoll_wait                 1282

/usr/src/linux-2.4.20.se1/arch/ia64/kernel/entry.S
        data8 ia64_ni_syscall           // 1279
reserved for sys_lookup_dcookie
        data8 sys_epoll_create          // 1280
        data8 sys_epoll_ctl
        data8 sys_epoll_wait

To overcome glibc issue, wrote the simple code as
follows...


#include <unistd.h>
#include <sys/syscall.h>
#include <errno.h>

#define SYS_epoll_create 1280

int main() {

        int rc;

        rc = syscall(SYS_epoll_create, 10);

        if(rc = -1) {
                printf("syscall Failed, %s %d\n",
strerror(errno), errno);
                return 1;
        } else {
                printf("syscall passed\n");
        }
}

Note: Also tried with '__NR_' instead of 'SYS'

----------------------------------------

This program returns with error code 38 - Function NOT
implemented.

Here is the patch :

.diff

Any help/thoughts will be much appreciated.

Regards,
GV
