PME GPE Enable (PMEGPE):
0b
0 = Do not generate GPE PME message when PME is received.
1 = Enable. Generate a GPE PME message when PME is received
(Assert_PMEGPE and Deassert_PMEGPE messages on DMI). This enables
the (G)MCH to support PMEs on the PCI Express* x16 Graphics Interface
port under legacy OSs.

Hot-Plug GPE Enable (HPGPE)
0b
0 = Do not generate GPE Hot-Plug message when Hot-Plug event is received.
1 = Enable. Generate a GPE Hot-Plug message when Hot-Plug Event is received
(Assert_HPGPE and Deassert_HPGPE messages on DMI). This enables the
(G)MCH to support Hot-Plug on the PCI Express* x16 Graphics Interface port
under legacy OSs.

General Message GPE Enable (GENGPE)
0b
0 = Do not forward received GPE assert/deassert messages.
1 = Enable. Forward received GPE assert/deassert messages. These general
GPE message can be received via the PCI Express* x16 Graphics Interface
port from an external Intel device and will be subsequently forwarded to the
Intel^® ICH6 (via Assert_GPE and Deassert_GPE messages on DMI).
