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,
