What's the performance gain from 1GB mappings in HAP tables like? What about just the (possible) extra 1GB mapping from this particular patch? Is it worth making guest-visible efforts like this (admittedly small) one? After all, the probably most frequently accessed 1GB starting at address 0x0 cannot be done with a 1GB mapping and we live with it. -- Keir On 22/02/2010 17:17, "Wei Huang" <wei.huang2@xxxxxxx> wrote: > To support 1GB host page, this patch changes the MMIO starting address > to 1GB boundary. > > Signed-off-by: Dongxiao Xu <dongxiao.xu@xxxxxxxxx> > Signed-off-by: Wei Huang <wei.huang2@xxxxxxx> > _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
