EXT4 fscrypt vs. eCryptfs vs. LUKS dm-crypt Benchmarks

Given the recent advancements of the EXT4 file-system with its native file-system encryption support provided by the fscrypt framework, here are benchmarks comparing the performance of an EXT4 file-system with no encryption, fscrypt-based encryption, eCryptfs-based encryption, and a LUKS dm-crypt encrypted volume.

The Changes & New Features For Linux 4.18

With the early release of Linux 4.18-rc1, feature development on Linux 4.18 is over and it's onto roughly eight weeks worth of testing and bug fixes. For those that are behind in their Phoronix reading with our extensive and original reporting on the Linux 4.18 merge window happenings, here is our recap of the big changes that made it into Linux 4.18. We are also in the process of firing off the start of our Linux 4.18 kernel benchmarks.

AMDGPU Performance Tests With New WattMan-Like Settings, Power Capping

With the recent stable debut of the Linux 4.17 kernel, one of the most common performance test requests coming in has been for checking out the Radeon WattMan-like support that was introduced with the Linux 4.17 AMDGPU code for recent generations of Radeon graphics card. Here are some benchmarks of that and on a somewhat related note also some Linux gaming benchmark results when carrying out some power capping tests to restrict the graphics card to a given Wattage.

Some Of The Early Ideas For Intel's New FreeBSD Improvement Effort

Two weeks back we shared the news that one of Intel's open-source Linux graphics driver veterans decided to change roles and is now focused on improving FreeBSD for Intel hardware. Ben Widawsky is working on FreeBSD improvements that can at least relate to Intel and it turns out the company has a new team of developers on the task.

NVIDIA Contributes EGLStreams Improvements For GNOME's Mutter Wayland Support

GNOME's Mutter Wayland compositor support is among the few Wayland implementations offering support for EGLStreams so it can play along with the approach used by the NVIDIA proprietary driver as an alternative to the GBM API used by the open-source graphics drivers. One of the NVIDIA engineers has just furthered along Mutter's EGLStreams support.

RISC-V Changes Merged For Linux 4.18, Early Perf Subsystem Work

Initial RISC-V architecture support was added to the Linux 4.15 kernel and in succeeding kernel releases have been mostly modest updates. With Linux 4.18 the RISC-V changes are on the small side still, but with a few notable additions for this open-source, royalty-free processor ISA.

Better Wine Benchmarking This Summer For Windows Programs On Linux

Improvements are underway for Wine benchmarking to help ensure this open-source program for running Windows apps/games on Linux and other operating systems continues without introducing performance regressions and for being able to quantitatively verify expected performance improvements around its Direct3D/OpenGL/Vulkan code-paths, among other areas of Wine.

Binutils 2.31 Slated For Fedora 29

To little surprise given that Fedora Linux always strives to ship with a bleeding-edge GNU toolchain, for the Fedora 29 release this fall they are planning to make use of the yet-to-be-released Binutils 2.31.

The NVIDIA vs. Open-Source Nouveau Linux Driver Benchmarks For Summer 2018

It has been some months since last delivering any benchmarks of Nouveau, the open-source, community-driven for NVIDIA GPUs. The reason for not having any Nouveau benchmarks recently has largely been due to lack of major progress, at least on the GeForce desktop GPU side, while NVIDIA has continued to contribute on the Tegra side. For those wondering how the current performance is of this driver that started out more than a decade ago via reverse-engineering, here are some benchmarks of the latest open-source Nouveau and NVIDIA Linux graphics drivers on Ubuntu.
