When thinking about multithreading the device model, it occurred to me
that it's a little odd that we're doing a memcmp to determine which
portions of the VRAM has changed. Couldn't we just use dirty page
tracking in the shadow paging code? That should significantly lower the
overhead of this plus I believe the infrastructure is already mostly
there in the shadow2 code.
Is this a sane idea? Regards, Anthony Liguori _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
