Hi,I was going through Xen address space layout, and i was thinking Xen uses upper 64MB in x86-32 mode and 168MB in x86-32 PAE mode. But from xen/include/asm-x86/config.h it is not clear where different mappings are for 32-bit and 32-bit PAE modes. I see that FRAMETABLE_MBYTES is hard coded as 96, and other macros are also summing up to 168MB, not 64MB. Does it mean, now Xen takes 168MB in both modes? or am i missing anything? thanks, -- bvk-chaitanya _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
