How do I disable LPM on my SSD?
I'm trying to figure out how to disable Link Power Management on my SSD through Linux. I've googled around a bit but all I can find is how to do it on Windows.

# cat /sys/class/scsi_host/host0/link_power_management_policy
max_performance In my case i think it is "disabled", since it is in max_performance... Echoing it a "min_performance" would enable it. That change is not permanent. Do you want to disable it for any particular reason? There is also pcie_aspm (active state power management) that (at least for me) caused a lot of problems witch certain hardware. |
