  • Thread-topic: [PATCH] x86: Back port from latest Linux kernel to enable C2/C3 entry via MWAIT
Current xen-linux (2.6.18) not include support for Cx MWAIT entry
method. Back port from latest Linux kernel (already there since 2.6.23).
Without this patch, _CST method couldn't get C states with FFH address
space type.
