Linus Torvalds has announced the release of the Linux Kernel version 5.17, with one of the most prominent features being the new AMD P-State driver for modern CPUs.

From the release announcement: "So we had an extra week of at the end of this release cycle, and I'm happy to report that it was very calm indeed.  We could probably have skipped it with not a lot of downside, but we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it's all good."

You can view a human-readable changelog thanks to the folks at Kernel Newbies but here's some of the highlights:

  • AMD P-State driver - a performance scaling driver that introduces a new CPU frequency control mechanism on AMD Zen based CPU series in Linux kernel. Designed to give better power efficiency and can help the likes of the Steam Deck.
  • Updates for next-generation AMD GPUs.
  • More improvements to bring up support for Apple Silicon.
  • Initial support for Intel Raptor Lake S graphics.
  • Support for custom fan curves found on some ASUS ROG laptops.
  • New driver for x86 Android tablets.
  • Security: straight-line-speculation mitigations.
  • An addition for System76 EC specific functionality.
  • New driver for Lenovo Yoga Book.

And much more, that's just me cherry-picking a few bits that stood out.

If that P state driver improves my 2600X i'll be a happy man. I'm not unhappy with it but the more the merrier.
