[Qemu-devel] [PATCHv3 0/6] ui/vnc: update optimizations

[Peter Lieven <pl@kamp.de>]

this series includes several optimizations for the ui/vnc guest to server and server to client
update cycles. comments/reviews appreciated.

v2->v3: - fixed checkpatch warnings [Stefan]
        - fixed an old coding style violation [Stefan]
v1->v2: - new patches 2,4,5
        - patch3: added performance test [Anthony]
        - patch3: further optimized the vnc_update_client by searching for the next zero bit
          with find_next_zero_bit.
        - patch3: further optimized vnc_dpy_switch by using bitmap_set to mask bits dirty.
