The work going on for over a year to optionally flush the L1 data cache on context switching is going to try again for the next kernel cycle as an opt-in feature for select tasks. This was the feature rejected last year by Linus Torvalds that went on to "beyond stupid" and other concerns about it when it was trying to be mainlined originally...

While the AMD Ryzen 9 5900HX performance is great on Linux once overcoming any laptop support quirks like with the ASUS ROG Strix G15 "AMD Advantage" laptop running into keyboard and WiFi issues on Linux depending upon the kernel version, how does the performance compare to Microsoft Windows 10? Here are some benchmarks of that ROG Strix G15 AMD laptop under Windows 10 as shipped by ASUS against Ubuntu 21.04 when upgraded to the Linux 5.13 stable kernel.

The NVMe specification provides for an abrupt shutdown mode over the normal/safe shutdown command if needing to quickly get the NVMe solid-state storage ready for powering off as quickly as possible. Currently the Linux kernel isn't making use of the NVMe abrupt shutdown command but a proposal by Micron is looking to begin its usage...

Last week AMD released their AOCC 3.1 compiler that is their downstream of LLVM Clang/Flang and carrying various yet-to-be-upstreamed patches for benefiting their latest processors. While just a point release, curiosity got the best of me for firing up benchmarks of this latest AMD Optimizing C/C++ Compiler release.

There is the phenomenon on Linux where when double-buffered rendering and missing vblanks can lead to the GPU running at a lower frequency when instead the opposite should happen so it will try to not miss vblanks in the first place. In the past there's been talks of "boost" support in the GPU drivers or also workarounds from user-space like dynamic triple buffering, but sent out this week is a new proposal around DMA-Fence deadline awareness as another means of addressing this problem...

Going on for more than one year now is the effort for supporting KVM virtualization with the RISC-V architecture, which is very much important for RISC-V processors to be able to eventually take lift in the server space. The KVM RISC-V enablement work is now up to its nineteenth revision but not yet clear if it's ready for mainlining...

Google engineers and other parties are interested in being able to create swap spaces on Linux systems that would be reserved just for system suspend/hibernation purposes and not for generic swapping to disk...

Following last week's big kernel in the form of Linux 5.14-rc2, rc3 is now available and it's much saner this week with fewer changes and those scattered changes being on the smaller side...

The BLAKE3 cryotpgraphic hash function that was announced last year and based on its predecessor BLAKE2 has now reached version 1.0 for its official/reference software implementation. BLAKE3 continues to be much faster than BLAKE2 while also being much faster than the likes of SHA-1/SHA--2/SHA-3 and even MD5 while being more secure...

When sticking to Wine recommendations of maintaining separate prefixes per-application, a lot of system files get duplicated for each game/application and in turn leading to significant bloat. With the current state of Wine it can mean hundreds of megabytes per prefix in duplicated files. But proposed reflink patches for Wine are aiming to cut down on this severe bloat...

This past week were the initial Linux benchmarks of the Ryzen 9 5900HX with the ASUS ROG Strix G15 laptop. Ubuntu was used as the default test platform as usual given its popularity and arguably the most relevant Linux distribution to use given that it's the most common Linux distribution at the moment for preloads on laptops by multiple vendors. In any case, as usual many users were quick to say "but Arch Linux!" as if it was going to make a dramatic difference in my findings. Well, here are some Ubuntu 21.04 versus Arch Linux benchmarks on that AMD Advantage laptop.

The latest Linux kernel feature proposed by Microsoft that is now working its way to the mainline kernel is IMA-based target measurements for the Device Mapper (DM) subsystem for enhanced security...

Intel "Cannon Lake" processors were rare in the first place with being limited to the Core i3 8121U but given that no production SKU ever materialized with the "Gen10" graphics enabled, Intel's Linux engineers are finally moving ahead in eliminating the rest of the Cannon Lake / Gen10 graphics support code...

The Debian release team has just announced their planned release date for Debian 11...

One of the low-level exciting kernel advancements being worked on at the moment is the new "folios" struct for improving Linux memory management. Tests by those involved found that in some conditions Linux kernel builds for example could be up to 7% faster. Given the recent folios v14 patches being published, I took them for a spin on an AMD EPYC server to see the impact on overall performance...

In addition to still working on moving from Ubuntu 16.04 to 20.04 LTS for its base, Ubuntu Touch has also begun engaging in another important project: supporting Voice over LTE (VoLTE) with Ubuntu Touch...

It's been a while since last looking at the performance of AMD's official "AMDVLK" open-source Linux Vulkan driver against that of the popular Mesa "RADV" Radeon Vulkan driver. But here are some fresh benchmarks for those interested while using the latest-generation Radeon RX 6800 XT graphics card paired with the in-development Linux 5.14 kernel across testing both Vulkan drivers.
