Does the Fit-PC2 support DIPM?

Post by monnier »

SSD drives seem to consume a lot less when DIPM (Device Initiated Power Management) is enabled. AFAIK, to enable it under GNU/Linux, you need to set /sys/class/scsi_host/host0/link_power_management_policy to "min_power", but I don't see this config file on my Fit-PC2.

So is it a limitation of the Fit-PC2's chipset? Or a limitation of the current Linux kernel drivers? Something else?

"link_power_management_policy" available for drives in AHCI mode, chipset on fit-pc2/2i limited to IDE.
