| 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. Signed-off-by: Wei Gang <gang.wei@xxxxxxxxx> Jimmy
