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 arch_init.c | 43 +++++++++++++++++-------------------------- include/qemu-common.h | 24 ++++++++++++++++++++++++ util/bitops.c | 23 ++++++++++++++++++++--- util/cutils.c | 35 +++++++++++++++++++++++++++++++++++ 4 files changed, 96 insertions(+), 29 deletions(-) -- 1.7.9.5
