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.
