On: Adding 16 kb page size to Android

[nullindividual]

Windows has 4K, 2M, and 1G page sizes on x86-64.

Normal, large and huge. But default normal pages (which is what Android is changing) are 4K. FWIW, Itanium and Alpha had 8K default pages.

I wonder why Microsoft stayed with 4K for AArch64.

Microsoft wanted to make x86 compatibility as painless as possible. They adopted an ABI in which registers can be generally mapped 1:1 between the two architectures.

I was confused as to why you were posting incorrect information when this thread already contained the correct information.

I wonder who requested the 1G page size be implemented and what they use it for...

Another thread says virtual machines.
