[Qemu-devel] [PATCH v2 0/2] s390x/kvm: Properly detect page size of initial memory

[David Hildenbrand]

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()
