From a follow up post on Mastadon https://social.treehouse.systems/@AsahiLinux/110497512340479...:

"Also in this update:

We now have a cpuidle driver, which significantly lowers idle power consumption by enabling deep CPU sleep. You should also get better battery runtime both idle and during sleep, especially on M1 Pro/Max machines.

Thanks to the cpuidle driver, s2idle now works properly, which should fix timekeeping issues causing journald to crash.

Also thanks to the cpuidle driver, CPU boost states are now enabled for single- and low-threaded workloads, noticeably increasing single-core performance.

Thermal throttling is now enabled, which should keep thermals in check on fanless (Air) models. There was never a risk of overheating (as there are hard cutoffs), but the behavior should now more closely match how macOS works, and avoid things getting too toasty on your lap.

Random touchpad instability woes should now finally be gone, thanks to bugfixes in both the M1 (SPI) and M2 (MTP) touchpad drivers.

A bugfix to the audio subsystem that fixes stability issues with the headphone jack codec.

New firmware-based battery charge control, which offers fixed a 75%/80% threshold setting. To use this, you need to update your system firmware to at least version 13.0, which you can do by simply updating your macOS partition to at least that version or newer. This new charge control method also works in sleep mode.

U-Boot now supports the Type A USB ports (and non-TB ports on the iMac), so you can use a keyboard connected to any port to control your bootloader.

And last but not least, this kernel release includes base support for the M2 Pro/Max/Ultra SoCs! We are not enabling installs on these machines yet as we still have some loose ends to tie, but you can expect to see support for this year's new hardware soon."

Does this mean Apple gave them prerelease hardware early? Might apple start helping these guys more - like for example donating a 5 person dev team for a few months maybe?

M2 Pro/Max were available in January. I think they needed to wait until now to be sure the M2 Ultra announcement didn't have too huge of changes from the way the M1 Ultra was done. In other words, the Asahi Linux team don't have an M2 Ultra to test on, they are getting ready for when they can get some test results, possibly from users.

Please consider donating if you have the means. https://asahilinux.org/support/

It means that Apple isn't radically changing the internals of the SOC every year.

>Apple’s first iPhones ran on Samsung SoCs, and even as Apple famously announced that they were switching to their own designs, the underlying reality is that there was a slower transition away from Samsung over multiple chip generations. “Apple Silicon” chips, like any other SoC, contain IP cores licensed from many other companies; for example, the USB controller in the M1 is by Synopsys, and the same exact hardware is also in chips by Rockchip, TI, and NXP. Even as Apple switched their manufacturing from Samsung to TSMC, some Samsung-isms stayed in their chips… and the UART design remains to this day.
