Of the performance-related changes with Linux 5.12 worth noting is faster AES-NI XTS performance for systems relying upon return trampolines "Retpolines" as part of the CPU's Spectre V2 mitigations. On the Intel side this primarily impacts older CPUs where Retpolines is still used while on the AMD side through Zen 3 the Retpolines is still relied upon, which as shown by these benchmarks is now much better off for AMD Ryzen AES XTS performance as measured by Cryptsetup...

The Linux kernel source tree following the eventful 5.12 merge window is at 28.81 million lines in the source tree across more than sixty thousand files. The largest in-tree kernel driver continues to be the AMDGPU kernel driver, which in the next kernel release or so should be crossing three million lines...

Linus Torvalds issued the first release candidate tonight of Linux 5.12 following an unusual merge window...

The Linux 5.12 merge window was off to a rough start due to winter storms preventing Linus Torvalds from merging changes for nearly one week, but in any case he appears to have caught up and the Linux 5.12-rc1 kernel is expected later today to end out the merge window. Here is a look at the many exciting changes coming for Linux 5.12.

There have been plenty of new and updated benchmarks over the course of February ahead of upcoming CPU and GPU launches...

Last week the Linux Mint project shared the troubling news how many of its users are behind on important security updates or in some cases even running end-of-life versions. In trying to help address the issue, Linux Mint is working on improvements to its Update Manager to encourage users to apply updates...

Back in March 2019 Xilinx announced they were looking to upstream their Alveo FPGA accelerator drivers into the mainline kernel code. They followed through with posting the initial kernel patches and then fast forward to the end of 2020 they posted a new iteration of the patches. This month the company, which is in the process of being acquired by AMD, posted the third iteration of their open-source Linux kernel driver patches...

For more than four years Apple's MacBook Pro has featured the Touch Bar as a display / control bar input device above the keyboard on these laptops. While there have been reports of Apple potentially phasing out the Touch Bar in future models, an open-source Linux driver for the component is still working its way toward the mainline kernel...

Greg Kroah-Hartman this week sent in "the large set of char/misc/whatever driver subsystem updates", which as usual -- given it's a catch-all area of kernel drivers not fitting well into other subsystems -- there is an interesting mix of additions...

For those enjoying the Valheim, the new survival/sandbox game that has been an incredible success and sold more than four millions of copies so far while being a low-budget indie game, Mesa should be providing better performance when using its OpenGL renderer...
