[Xen-devel] How to disable pae in xen

[LIU Wei <liuw@xxxxxxxxx>]

Hi, xen experts

In early time xen, there is an option in Config.mk to toggle PAE mode.

XEN_TARGET_X86_PAE

But in xen-3.3.0, it's gone. The only thing I find is a cr4 operation in
xen/arch/x86/setup.c

mmu_cr4_features = X86_CR4_PSE | X86_CR4_PGE | X86_CR4_PAE

If I want to disable PAE in xen-3.3.0, should I delete the last feature? And, I
wonder if there are any other variables I need to touch.

Any reply is welcomed.

Regards
LIU Wei
