does hangover work on arm server，pagesize 64k？

Most likely not. We never tested page sizes other than 4k

I've never used hangover (waiting for ppc64le support) but I'm pretty sure it doesn't because it relies on qemu which does a terrible job at emulating different page sizes. The Linux kernel should really support multiple simultaneous page sizes like MacOS does.

Also, which arm chips do have a 64K page size? I know M1 chips use 16K.

By the way most chips nowadays support multiple page sizes, so using 4K should be as wasy as recompiling your kernel with a different config. Performance penalties from 64K->4K are minimal.
