在FADT table中有个字段prederred_PM_profile,在SPEC中是如下叙述的# Y* K7 _/ h# r2 K
5 Y! q: c( t: [; u0 E
This field is set by the OEM to convey the preferred power 3 _+ g2 y/ Z/ f( b: P9 Y: ~1 p: l. ]management profile to OSPM. OSPM can use this field to set 4 @$ {# m- u: P4 f( ~9 ldefault power management policy parameters during OS 1 ~* P) B1 s ]3 g1 n+ _# ]* j0 Zinstallation. : r; l+ N2 K6 ]- c% R
