         The HPET provides a stable time base on SMP

         systems, unlike the TSC, but it is more expensive to access,

         as it is off-chip.  You can find the HPET spec at

         <http://www.intel.com/hardwaredesign/hpetspec.htm>.

         <http://www.intel.com/hardwaredesign/hpetspec_1.pdf>.



         You can safely choose Y here.  However, HPET will only be

         activated if the platform and the BIOS support this feature.
