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

[Peter Lieven]

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
