[Qemu-devel] [RFC v1 2/2] spapr: Force gaps between DIMM's GPA

2015-10-09 Thread Bharata B Rao
Mapping DIMMs non contiguously allows to workaround virtio bug reported earlier: http://lists.nongnu.org/archive/html/qemu-devel/2015-08/msg00522.html In this case guest kernel doesn't allocate buffers that can cross DIMM boundary keeping each buffer local to a DIMM. Suggested-by: Michael S. Tsirk
