Phoronix: Ice Lake Xeons Will Ramp Up Frequencies Slower, So Linux Is Preparing A Workaround

While being very eager to learn more about Intel next-gen Ice Lake Xeon processors as their move in the server space finally from 14nm to 10nm+, we continue to learn new tid-bits from the open-source Linux kernel activity...

Non-laptop Ice Lake?! Finally!!!

They didn't even release an H-class Ice Lake processor.

In an ideal world the CPU should be notified if it is an interactive program that requires processing or some background "shit".

On a server, everything is background.

Services with active connections are "interactive" ...

On a desktop, another example of "background shit" are browser tabs. Only the active one should be able to clock the CPU above its base clock.
In fact, personally I would have liked it if the non-active tabs would pause completely.
Like I said, in an ideal world.

There are extensions which "suspends" tabs which is very useful for older machines with little RAM.

Unfortunately I don't care about RAM usage but about CPU usage and want them to stay in ram but don't allow any execution from them which as far as I know there's no extensions for. Not sure if it's because it would break lots of webpages or if it's because there's no API for it.

Thanks. I haven't looked at extensions for this in quite some time.
I am also not concerned about the RAM usage, but the CPU usage drains the battery on my laptop.
I can almost get double the amount of time out of my laptop if I close the browser during power outages.

There is support for that in the kernel. Has been there for quite a while.
Linux userspace does not make much use of it though.
Wakelocking has to be 10 years+. Although not in vanilla.
