I've checked in a patch to do that. It still leaves the screen uncleared if the 'keep vga' option is specified to Xen (that's the mode where Xen tries to share with dom0, for debugging purposes). In that mode it seems unwise to clear screen data when we don't have to. Jan talked about orig_x and orig_y but we don't actually pass such data to dom0 for vesa consoles, so there's no trivial solution there. I think what we have now is fine, since debuggability is still available by specifying that Xen share the vga console with dom0. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
