This is based on the patch
[PATCH for-4.0?] exec: Only count mapped memory backends for
qemu_getrampagesize()
While the detection on s390x of the maximum ram pagesize works by pure luck,
we should try to do better. Especially, once "-mem-path" is replaced
by memory backends, the current approach will break.
Configure the maximum page size after configuring initital memory. Provide
a function to detect the maximum ram pagesize
I think this can be deferred to 4.1 as I don't think anything is actually
broken right now.
v1 -> v2:
- Add a better comment describing that only initial memory is considered
- Add "exec: Introduce qemu_getmaxrampagesize() and rename
qemu_getrampagesize()"
David Hildenbrand (2):
s390x/kvm: Configure page size after memory has actually been
initialized
exec: Introduce qemu_getmaxrampagesize() and rename
qemu_getrampagesize()

But let's see first if this is the right approach. -- Thanks, David / dhildenb

I will resend both patches (once I find some spare time ;) ). I will also try to test, nly have to find a setup where I can use huge pages. -- Thanks, David / dhildenb
