Linux Kernel 4.9 Officially Released (kernel.org)

"As expected, today, December 11, 2016, Linus Torvalds unleashed the final release of the highly anticipated Linux 4.9 kernel," reports Softpedia. prisoninmate shares their article: Linux kernel 4.9 entered development in mid-October, on the 15th, when Linus Torvalds decided to cut the merge window short by a day just to keep people on their toes, but also to prevent them from sending last-minute pull requests that might cause issues like it happened with the release of Linux kernel 4.8, which landed just two weeks before first RC of Linux 4.9 hit the streets... There are many great new features implemented in Linux kernel 4.9, but by far the most exciting one is the experimental support for older AMD Radeon graphics cards from the Southern Islands/GCN 1.0 family, which was injected to the open-source AMDGPU graphics driver...

There are also various interesting improvements for modern AMD Radeon GPUs, such as virtual display support and better reset support, both of which are implemented in the AMDGPU driver. For Intel GPU users, there's DMA-BUF implicit fencing, and some Intel Atom processors got a P-State performance boost. Intel Skylake improvements are also present in Linux kernel 4.9.

There's also dynamic thread-tracing, according to Linux Today. (And hopefully they fixed the "buggy crap" that made it into Linux 4.8.) LWN.net calls this "by far the busiest cycle in the history of the kernel project."

    The kernel is pretty damn useless if the userland is inaccessible because the init system broke unexpectedly and the system didn't boot properly.

    An OS needs a robust kernel, a robust init system and a robust userland. If even just one of those isn't working right, the entire OS is useless.

    Duh, "apt purge systemd" and you can enjoy a reliable init. Just like the solution for most sound problems is "apt purge pulseaudio". Or, closing a link-local security hole by "apt purge avahi-daemon". I think you get the pattern.

    Actually, you use command prompt / terminal for tons of things in Windows. I support Windows systems professionally.

    Powershell's OOP scripting language is pretty neat, at least on the surface. But it basically breaks down any time you want to do something complex, while bash/sed/awk/piping holds up strong in Linux.

    He should have been shunned from the Linux ecosystem after PulseAudio. It's better than it was 8 years ago but, it's still unreliable garbage that sometimes flakes out while trying to solve a problem that no one actually has. For the vast majority of users, life was much better when bits were directly blasted to ALSA. I'd much rather deal with the limitations of ALSA than the unpredictability of PulseAudio.
