Hi~folks,
I'm interesting about power management for SATA but wondering about
AHCI ALPM, SATA HIPM and DIPM.
There are some questions would like to understand.
* ALPM is HIPM for AHCI?
* If ALPM is enabled but SATA HDD does not support HIPM (only DIPM),
ALPM is effective?
* hdparm -B is "Query/set Advanced Power Management feature".
This setting ("Advanced Power Management") is for DIPM?
Thanks you very much.
Best Regards,
Edward
