[Qemu-devel] [PATCHv4 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.

v3->v4: - patch 1,4,6 unchanged
        - patch 2: fix 2 missing changes from 16 -> VNC_DIRTY_PIXELS_PER_BIT [Wenchao]
        - patch 3: fixed missing roundup of width in vnc_dpy_switch [Wenchao]
        - patch 3: fixed x offset calculation in vnc_refresh_server_surface
        - patch 5: fixed missing roundup of width in vnc_dpy_update, cleaned up function
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.

Peter Lieven (6):
  ui/vnc: introduce VNC_DIRTY_PIXELS_PER_BIT macro
  ui/vnc: derive cmp_bytes from VNC_DIRTY_PIXELS_PER_BIT
  ui/vnc: optimize dirty bitmap tracking
  ui/vnc: optimize clearing in find_and_clear_dirty_height()
  ui/vnc: optimize setting in vnc_dpy_update()
  ui/vnc: disable adaptive update calculations if not needed
