Subject: What means Hugepage? 8KiB,16KiB,..,2MiB or 4MiB?

Message-ID: <998d0e4a0803251503v7bf20ad4ndb0e21b1eead7f9d@mail.gmail.com> (raw)
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.
