Linux On The Apple M1 Preparing Better Performance With In-Development CPUFreq Driver

Phoronix - Wed, 02/16/2022 - 20:45
As with most modern SoCs/processors, proper CPU frequency scaling / performance state management is absolutely critical for achieving good performance out of the hardware either for ensuring the CPU is hitting its capable performance states and also to reduce power consumption / heat when not needed in order to avoid thermal throttling and prolonging battery life. Fortunately, a proper CPUFreq driver for the Apple M1 is in development for Linux and is allowing for a combination of enticing performance and good battery life for this community-driven, open-source support around the Apple Silicon...

Radeon Vulkan Driver Lands Dynamic VRS To Help With Power Savings - Helps The Steam Deck

Phoronix - Wed, 02/16/2022 - 19:04
Back in January I wrote how Valve is working on dynamic Variable Rate Shading (VRS) for the Mesa Radeon Vulkan driver "RADV" to dynamically control the shading performance to help with battery life. That work has now successfully been merged into Mesa 22.1 for the open-source AMD Radeon Linux graphics stack...

Bcachefs Might Be Ready For Upstreaming In Linux This Year

Phoronix - Wed, 02/16/2022 - 18:36
The Bcachefs file-system that was born out of the Linux kernel's block cache code has over the past few years matured greatly. Now in 2022 the core fundamentals of the file-system are "pretty close to done" and will hopefully be mainlined this calendar year into the Linux kernel...

AMD P-State Support Coming For The CPUPower Tool

Phoronix - Wed, 02/16/2022 - 18:13
With the forthcoming Linux 5.17 kernel there is the new AMD P-State driver aiming to provide better power efficiency than the ACPI CPUFreq driver that has long been used on AMD platforms. For complementing that AMD P-State driver, AMD has also been working on adding their CPU P-State support to Linux's cpupower tool...

Proton 7.0 Released With More Games Running On Linux, EAC Support, Many Other Updates

Phoronix - Wed, 02/16/2022 - 17:21
Ahead of the Steam Deck beginning to ship at month's end, Valve overnight released Proton 7.0-1 as the newest version of their software that allows many Windows games to run on Linux with great success. Proton 7.0 is rebased against the new upstream Wine 7.0 while also having many other changes in tow...

Archive files on your Linux desktop with Ark for KDE

opensource.com - Wed, 02/16/2022 - 16:01

When I finish with a project, I often like to take all the files I've created for the project and put them into an archive. It not only saves space, but it gets those files out of my way, and prevents them from turning up as results when I use find and grep to search through files I consider current.

Continuously debug your open source project with OSS-Fuzz

opensource.com - Wed, 02/16/2022 - 16:00

OSS-Fuzz is a free service that continuously runs fuzzers for open source projects. This GitHub repository manages the service and enrolling in it is handled by pull requests.

Once a project has integrated with OSS-Fuzz, the fuzzers affiliated with that project run daily—continuously and indefinitely. OSS-Fuzz emails maintainers when a bug is found and also has a dashboard with details about all issues found (stack traces, artifacts for reproducing issues, and so on).
