[Qemu-devel] [PATCH V3 0/2] Xen VGA dirtybit support

[<anthony.perard@citrix.com>]

From: Anthony PERARD <anthony.perard@citrix.com>

Hi,

This two patches provides the support for sync dirty bitmap, especially useful
for the VGA output.  The sync dirty bitmap is not provided for Xen 3.3.

Change v2 -> v3:
  * use the new log_dirty parameter of set_memory clients.
  * fix some mistakes related to the use of TARGET_PAGE_MASK and
    TARGET_PAGE_ALIGN macro in xen_client_set_memory.
  * The patch that provide log_start/log_stop in CPUPhysMemoryClient as already
    been applied.

Change v1 -> v2:
  * Introduce a patch to put log_start/log_stop in CPUPhysMemoryClient;
  * There are now only one function to get/check for old physmapping
    (get_physmapping);
  * The function xen_sync_dirty_bitmap only do a sync on range that are
    physmapped and only on one range;
  * Physmapping list and CPUPhysMemoryClient is now in XenIOState structure;
  * Introduce log_for_dirtybit that hold the range for dirty bit tracking.
