Don't a lot of CPUs like Snapdragons already have "performance cores" and "efficiency cores" that the kernel has to be able to recognize in order to switch between them? This sounds neat but I'm just curious what's different between these situations.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The only difference is the hardware. Intel has their own version that has been in the kernel for a long time. Amd has been struggling with landing the concept.
I'm happy with my abundance of p-cores! Hopefully they don't nail it.
Even Intel has these. I think this patch set goes a bit further and takes into account the silicon lottery differences between cores (according to the patch series)
I'm using the patch set on my framework 7840u and didn't notice a difference though, though this is really YMMV.
Did you do benchmarks? It probably doesn't help much for heavily multi threaded apps, as they should use all cores anyway. And most apps aren't performance critical, altough it might stabilize fps in games.
I didn't measure performance, I was talking about battery life, but no, I didn't do any benchmarks.
