[Qemu-devel] [PATCH 0/2] ps: memhp: enforce gaps between DIMMs

[Igor Mammedov]

it's a simplier way suggested by Michael S. Tsirkin
to workaround virtio bug reported earlier:
http://lists.nongnu.org/archive/html/qemu-devel/2015-08/msg00522.html
where virtio can't handle buffer that crosses border
between 2 DIMM's (i.e. 2 MemoryRegions).

idea is to leave gaps between DIMMs, making their GPAs
non contiguous, which effectively forces kmalloc
to not use DIMM if buffer doesn't fit inside of it.

Igor Mammedov (2):
  memhp: extend address auto assignment to support gaps
  pc: memhp: force gaps between DIMM's GPA
