So this means that the cache information will be "wrong" when the CPU
is in the lower power states and only correct for the higher ones?
I'm not familiar with how these values are used; are you and do you
know if this will have any weird or unexpected effects?
Would it be better to use the cache size for the lower rather than
the higher states or does this not matter much?



Best,
