Phoronix: The Features You Won't Find In The Linux 4.12 Kernel

While Linux 4.12 has many new features that amount to over one million new lines, 4.12 goes without some features we sure would have loved to see mainlined in time for this next kernel release...

By having the kernel released on saturday instead of sunday, what subsystems/pull requests arrived too late?

[Ekland]

Well bcachefs can't be merged until it is actually pushed upstream, and the author still have features and bugs to fix before he will do that, which in turn sounds wise.

ZFS in mainline can only happen if either Linux or ZFS change license, which is extremely unlikely. The OpenZFS guys would likely be willing to relicense their changes to the ZFS codebase in a GPLv2 compatible manner, but their code is derived from ZFS which is owned by Oracle, and as such it's pointless unless Oracle relicenses the original project.

we hope for 4.13.

Some of you out there may have also been hoping AMD had some magical Ryzen patches for Linux 4.12, but none of the material merged this cycle referenced Zen/Ryzen improvements.

Do we know of any Ryzen issues that are caused by the kernel? I don't think so. There are no patches because we don't need them. Ryzen works fine already.

Well, AMD could send in something like Intel pstate for better reclocking capabilities, current clock governors are far from optimal.

Ryzen handles it's power states in hardware, doesn't it? At least that's what AMD says.

What aufkrawall mentioned + hwmon patches. There is no support for reading power/temp metrics currently.

then distros would need to autodetect ryzen and then disable the governors completly - but no distro does this afaik.

I'd also like to have shrink support for F2FS, if ever.
