My patch allows the use of masks to select many pages at once, much like the linux BADRAM patch. Masks can be specified using a forward slash, like, for example: badpage=0xa2000/0xef000,0x00100/0xfff00,0x01000 The masking scheme is unnecessarily restrictive. Why not just allow specification of inclusive ranges of pages? For example: badpage=0xa2000-0xa2fff,0x100-0x1ff,0x123-0x456 -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
