Execute Disable Bit

When enabled, the processor prevents the execution of code in data-only memory pages. This provides
some protection against buffer overflow attacks.
When disabled, the processor will not restrict code execution in any memory area. This makes the
processor more vulnerable to buffer overflow attacks.
Options available: Enabled/Disabled. Default setting is Enabled.

Energy Performance

The larger value in MSR_ENERGY_PERFORMANCE_BIAS register,
CPU will save more power but lose more performance.
