[Qemu-devel] [RFC][PATCH 0/9] live migration/buffer_is_zero optimizations

[Peter Lieven <pl@dlhnet.de>]

I will sent a list of optimizations that have been developed during
the last days. Your feedback is much appreciated.

@Paolo: Can you run your tests that you have made for your migration
optimzations that are now upstream against these patches.

Thanks,
Peter

Peter Lieven (9):
   move vector definitions to qemu-common.h
   add a function to find non-zero content in a buffer
   migration: add an indicator for bulk state of ram migration
   buffer_is_zero: use vector optimizations if possible
   migration: check for dup pages only in bulk stage
   migration: use XBZRLE only after bulk stage
   bitops: use vector algorithm to optimize find_next_bit()
   migration: do not send zero_pages in bulk stage
   migration: do not search dirty pages in bulk stage
