Hi~folks,
I'm wondering about AHCI ALPM, SATA HIPM and DIPM.
* ALPM is HIPM for AHCI?
* If ALPM is enabled but SATA HDD does not support HIPM (only DIPM),
ALPM is effective?
Thanks you very much.
Best Regards,
Edward

ALPM uses HIPM but there are other ways to achieve HIPM too (via
SControl).

Nope.
