[Xen-users] How to raise HZ to 1000 properly?

[David Muench <davemuench@xxxxxxxxx>]

Hi all,

I've been redoing my Asterisk domU, and decided to do it correctly
this time. This time I'm using zaptel and ztdummy, and that requires
HZ to be set to 1000. I've managed to do this, and Asterisk works
great with ztdummy, but I don't think I did it correctly. I've changed
include/asm-xen/asm/param.h thusly:

#ifdef __KERNEL__
# define HZ             1000            /* Internal kernel timer frequency */
# define USER_HZ        1000            /* .. some user interfaces are
in "ticks" */
# define CLOCKS_PER_SEC         (USER_HZ)       /* like times() */
#endif

#ifndef HZ
#define HZ 1000
#endif

And like I said, it works. But my bogomips are now 25100.28, whereas
my other domU's are more like 2300-2400.

What's the right way to do this?

Thanks,
Dave
