This set provides the ability for qemu to comminucate to the guest that it has been stopped. When the guest hits the watchdog on resume it will check if it was suspended before issuing the warning. Eric B Munson (4): Add flag to indicate that a vm was stopped by the host Add functions to check if the host has stopped the vm Add generic stubs for kvm stop check functions Add check for suspended vm in softlockup detector arch/x86/include/asm/pvclock-abi.h | 1 + arch/x86/include/asm/pvclock.h | 2 ++ arch/x86/kernel/kvmclock.c | 14 ++++++++++++++ include/asm-generic/pvclock.h | 14 ++++++++++++++ kernel/watchdog.c | 12 ++++++++++++ 5 files changed, 43 insertions(+), 0 deletions(-) create mode 100644 include/asm-generic/pvclock.h -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
