Hi, This patch expands shadow memory of guest BIOS. Currently the shadow memory is 0xc0000 - 0xdffff. It is used by VGA, gPXE, option ROM, but the size of these ROMs is around 40k->64k, so the area is not enough. I updated the previous patch. http://lists.xensource.com/archives/html/xen-devel/2008-12/msg01117.html I separate it into 2 parts. [1/2] replace e820 from 0xe0000 to oxeb000 (using E820_PHYSICAL_ADDRESS macro). [2/2] expand shadow mem from 0xc0000-0xdffff to 0xc0000-0xe8fff. Best Regards, Akio Takebe _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
