#Linux Kernel 6.15 Reaches End of Life, It’s Time to Upgrade to Linux Kernel 6.16 https://9to5linux.com/linux-kernel-6-15-reaches-end-of-life-its-time-to-upgrade-to-linux-kernel-6-16

#Linux 6.16.2, 6.15.11, and 6.12.43 kernels are now available for download at https://www.kernel.org

#Linux 6.17-rc2 is now available for public testing at https://www.kernel.org and Linus Torvalds says that "it's been a very calm week, and this is one of the smaller rc2 releases we've had lately.". Happy testing!

Happy #DebianDay!

Happy 32nd birthday to @debian, one of the oldest operating systems based on the #LinuxKernel, and the basis for #Ubuntu, #Kali, and #LinuxMint!

Thank you, #Debian community, for all your amazing work!

Introduction to VirtIO, Part 2: Vhost

https://blogs.oracle.com/linux/post/introduction-to-virtio-part-2-vhost

Jonah Palmer writes: ""[…] #Vhost is a key optimization to #VirtIO that was created to offload data-plane processing from #Qemu into more efficient components.

We’ll start off by taking a more in-depth look into the causes of overhead in the data plane of a pure VirtIO configuration. We’ll talk about the costly operations that are involved, such as VM exits, VM entries, context switches, and userspace processing by Qemu. Then we’ll introduce vhost and elaborate on how it addresses these issues by moving data-plane operations either into the kernel (kernel-based vhost) or into a specialized userspace process (via vhost-user).

We’ll then dive into both #kernel-based vhost and vhost-user architectures, examining each in detail—including their advantages, drawbacks, typical use cases, and how they affect performance. […]"

Linus QOTD from a recent #Linux #kernel merge commit:

""I am on a mission to write out the more obscure TLAs in order to keep track of them.

Because while math tells us that there are only about 17k different combinations of three-letter acronyms using English letters (26^3), I am convinced that somehow Intel, AMD and ARM have together figured out new mathematics, and have at least a million different TLAs that they use.""

PSA: never write "broken in #linux 6.15.3 and later"; instead specify which later versions you tested and turned out to be affected, too.

That will enable people that look into the bug to immediately see if it might be a 6.15.y specific problem or affects newer stable series (e.g. 6.16.y) as well?

It's also important to to determine if the problem only affected stable trees, or occurs in mainline (e.g. 6.17-rc1), too – which is important, as for the #kernel it often determines who is responsible.

Not to mention that "and later" becomes wrong once the issue is fixed.

Der Kernel ist gefixt – der Kern des Problems nicht.
2025 sind die meisten Linux-Distributionen im Kernel Y2K38-ready – doch einige bleiben verwundbar oder werden nie aktualisiert.

Wir haben die Lage analysiert, die Distributionen in Kategorien eingeordnet und den aktuellen Stand festgehalten.

At today's #Prague meetup, we successfully ran U-Boot on the Pixel 3 (including display support!), in addition to the Pixel 3 XL.
Also reported a regression in the Linux -next tree causing a crash at boot.

""This blog post introduces the concept of CPU hotplugging (and hot-unplugging) in a virtualized environment, and includes high level coverage of some of the key mechanisms involved. The focus is on #QEMU and #KVM, primarily with a #Linux guest, but general concepts are applicable to most other virtualization environments.""
