What means Hugepage?
Does it mean 8KiB? 16KiB? 32KiB? 64KiB? 2MiB? 4MiB?
The real page sizes of x86 and x86-64 are 4 KiB for this linux kernel.
But the page sizes can be soft 8 KiB or 16 KiB or 32 KiB or 64 KiB if it is implemented in the memory manager of the kernel.
But too they exist real page sizes of 2 MiB and 4 MiB that they have some reserved entries of TLB in the specs of Intel/AMD processors for these gigant pages.
