Multiple Req C2/C0 Enable (MRC2C0E):

been issued by the processor.

Enhanced Power Management Features Enable
(EPMFE):
Legacy Mode: the processor must ignore the snoop timers for
the purpose of deferring C state entry. PM_BMBUSYB signal
will be driven to the chipset when any snoop activity from
DMI is detected. It is held asserted for the duration described
by the C2 to C3 snoop timer while there is no snoop activity.
Enhanced Mode: the processor will use the snoop timers for
determining the proper time for allowing a power
management mode transition that was requested by ACPI
software. PM_BMBUSYB signal is never asserted. The allowed
behavior in this mode may be restricted by the Enhanced
Power Management Mode and the Enhanced Power
Management Snoop-detect Behavior fields.

Disable the C2 to C3 snoop timer based
transition. Never go past C2. IMC will never
issue the req_c3 message to DMI when a
wait_c3 message has been received from DMI.
