Linux 4.17 Will Allow Some Systems To Lower Their Idle Power Use Up To 10%+

[Marc.2377]

"Up to 10%+" literally means "Between 0 and 10%, or more". So, any value, then.

Heh, any unsigned integer value, at least one can hope

It's so confusing. I wanted to look at the code — just curious — so I went to the Rafel's git https://git.kernel.org/pub/scm/linux...ux-pm.git/log/ There's nothing relevant as far as I can see. Then I went to the commit he mentioned in the mail https://git.kernel.org/pub/scm/linux...11ce2adaff40f3 This commit doesn't even exist in the log! Wtf.

FWIW I ended up using the search for "rafael" name in the Torvalds' git https://git.kernel.org/pub/scm/linux...uthor&q=rafael

the CPU power usage can drop up to 10%

I've read the dev's email as that.

That doesn't sound realistic to me. Maybe the CPU power usage can drop up to 10%, but claiming the system's power usage can drop by that amount sounds completely unrealistic to me.

BY THE WAY, finally the developers are taking benefits by ACPI.

[Azrael5]

This kernel has so much important features that should have been the kernel provided for the upcoming distros. This kernel is essential.

Phoronix: Linux 4.17 Will Allow Some Systems To Lower Their Idle Power Use Up To 10%+

While last week was the main power management feature updates for the Linux 4.17 kernel merge window that included the new ACPI TAD driver, Rafael Wysocki today sent in a secondary set of feature updates and it includes a rather significant development for Linux power and performance...
