Intel Core i9 12900K P-State Governor Performance On Linux Review

Since Intel's Alder Lake launch one of the test requests to come in a few times has been about the Intel P-State CPU frequency scaling driver and how its performance differs with the various governor choices available for altering the CPU frequency scaling behavior. Now that Linux 5.16 stable is out and running in good shape on Alder Lake, here are some Core i9 12900K benchmarks looking at various CPU frequency scaling choices and their impact on raw performance as well as CPU thermals and power consumption.
With Alder Lake having seen fixes in Linux 5.16 as well as ADL-S graphics being enabled by default on this new kernel, it's a good target for carrying out the P-State testing. The main reader inquiry has obviously been about how how well these new Intel hybrid processors perform if moving from P-State "powersave" as is often the default governor on most distributions to instead using the "performance" governor that tends to keep the CPU in its higher performance states more aggressively than powersave.

Arti 0.5.0 is released: Robustness and API improvements
Arti is our ongoing project to create a working embeddable Tor client in Rust. It’s not ready to replace the main Tor implementation in C, but we believe that it’s the future. Right now, our focus is on making Arti production-quality, by stress-testing the code, hunting for likely bugs, and adding missing features that we know from experience that users will need. We're going to try not to break backward compatibility too much, but we'll do so when we think it's a good idea. ![]() | Programming Leftovers

| EasyOS Dunfell-series 4.2EasyOS was created in 2017, derived from Quirky Linux, which in turn was derived from Puppy Linux in 2013. Easy is built in woofQ, which takes as input binary packages from any distribution, and uses them on top of the unique EasyOS infrastructure.
Throughout 2020, the official release for x86_64 PCs was the Buster-series, built with Debian 10.x Buster DEBs.
EasyOS has also been built with packages compiled from source, using a fork of OpenEmbedded (OE). Currently, the Dunfell release of OE has been used, to compile two sets of binary packages, for x86_64 and aarch64.
The latter have been used to build EasyOS for the Raspberry Pi4, and first official release, 2.6.1, was in January 2021.
The page that you are reading now has the release notes for EasyOS Dunfell-series on x86_64 PCs, also debuting in 2021.
Ongoing development is now focused on the x86_64 Dunfell-series. The last version in the x86_64 Buster-series is 2.6.2, on June 29, 2021, and that is likely to be the end of that series. Releases for the Pi4 Dunfell-series are still planned but very intermittent.
The version number is for EasyOS itself, independent of the target hardware; that is, the infrastructure, support-glue, system scripts and system management and configuration applications.
The latest version is becoming mature, though Easy is an experimental distribution and some parts are under development and are still considered as beta-quality. However, you will find this distro to be a very pleasant surprise, or so we hope.
