    Subjectsched_getaffinity & sched_setaffinity returning -1 (errstr = Bad address)
    Hi
    
    I've been trying to use the sched_getaffinity &
    sched_setaffinity on
    kernel 2.6.4 and it is working on some systems and not
    others !
    It works fine on my aged dual CPU pentium pro box, but
    on the box I
    really want it to work on, the calls return -1 !
    
    The problem platform is a HP ML530 with 2 x Intel Xeon
    processors.
    I've tried it with and without hyperthreading enabled
    and the result
    is the same.
    I'm totally at a loss why this is happening and am
    wondering if it is
    related to the xeon processors ?
    This is a really nice feature I desperatley need to
    rid my dependance
    on SGI Irix.
    
    I'm using the sample code provided by Robert Lowe
    (below)
    
    /*
     * Example of sched_set_affinity and
    sched_get_affinity
     * Robert Love, 20020227
     */
    #include <stdio.h>
    #include <stdlib.h>
    #include <sched.h>
    #include <linux/unistd.h>
    
    /*
     * provide the proper syscall information if our libc
     * is not yet updated.
     */
    #ifndef __NR_sched_setaffinity
    #define __NR_sched_setaffinity241
    #define __NR_sched_getaffinity242
    _syscall3 (int, sched_setaffinity, pid_t, pid,
    unsigned int, len,
    unsigned long *, user_mask_ptr)
    _syscall3 (int, sched_getaffinity, pid_t, pid,
    unsigned int, len,
    unsigned long *, user_mask_ptr)
    #endif
    int main(int argc, char * argv[])
    {
    unsigned long new_mask = 2;
    unsigned int len = sizeof(new_mask);
    unsigned long cur_mask;
    pid_t p = 0;
    int ret;
    ret = sched_getaffinity(p, len, NULL);
    perror ("sched_affinity");
    printf(" sched_getaffinity = %d, len = %u\n", ret,
    len);
    
    ret = sched_getaffinity(p, len, &cur_mask);
    printf(" sched_getaffinity = %d, cur_mask = %08lx\n",
    ret, cur_mask);
    
    ret = sched_setaffinity(p, len, &new_mask);
    printf(" sched_setaffinity = %d, new_mask = %08lx\n",
    ret, new_mask);
    
    ret = sched_getaffinity(p, len, &cur_mask);
    printf(" sched_getaffinity = %d, cur_mask = %08lx\n",
    ret, cur_mask);
    
    return 0;
    
    }
    which when run yields on the Xeon box :
    
    sched_affinity: Bad address
     sched_getaffinity = -1, len = 4
     sched_getaffinity = -1, cur_mask = 0804851c
     sched_setaffinity = -1, new_mask = 00000002
     sched_getaffinity = -1, cur_mask = 0804851c
