[Qemu-devel] [PATCH 0/2] Optimization with AVX2 instruction

[Liang Li]

The buffer_find_nonzero_offset() will be called to check the zero page
during live migration, it's a hot function. buffer_find_nonzero_offset()
has already been optimized with SSE2 instructions, for platform that
supports AVX2, we can optimize this function with AVX2 instructions and
achieve about 25% performance gain.

Liang Li (2):
  cutils: add the AVX2 optimization
  configure: add --enable-avx2 option
