1) The observation of c-state information by acpidump and iasl is painful.
The kstat info of c-state should be good enough to be set by default for
all the platforms. Currently, deep_cstates_supported() will disable the
kstat info as well if it's not on Nehalem or not support HPET. Is it
worth to keep c-state kstat info? how about only check and control if the
system enter deep c-state?
2) Invariant TSC during deep-cstate could be indicated in the CPUID
0x8000_0007 function, we should check this feature instead.
3) Yeah, HPET is necessary, we need to check it
