Updated Windows NT Sync Driver Posted For The Linux Kernel

29 mars 2024 à 10:22
CodeWeavers' Elizabeth Figura has been working on the NTSYNC driver to implement Windows NT synchronization primitives for the Linux kernel in order to help the performance of various Windows games running on Linux by the likes of Wine / Valve's Proton (Steam Play). The third iteration of that driver was posted overnight as it seeks to go into the mainline Linux kernel...

Intel "Family 6" CPU Era Coming To An End Soon: Code Suggests Cooper Forest & Adams Lake

28 mars 2024 à 17:25
Since the mid-90's with the P6 micro-architecture for the Pentium Pro as the sixth-generation x86 microarchitecture, Intel has relied on the "Family 6" CPU ID. From there Intel has just revved the Model number within Family 6 for each new microarchitecture/core. For example, Meteor Lake is Family 6 Model 170 and Emerald Rapids is Family 6 Model 207. This CPU ID identification is used within the Linux kernel and other operating systems for identifying CPU generations for correct handling, etc. But Intel Linux engineers today disclosed that Family 6 is coming to an end "soon-ish"...

GNU Coreutils 9.5 Can Yield 10~20% Throughput Boost For cp, mv & cat Commands

28 mars 2024 à 16:35
While the uutils Rust-written Coreutils effort has been chugging along, the upstream GNU Coreutils effort is showing no signs of slowing down. Out today is GNU Coreutils 9.5 with yet more feature work and bug fixes including a security fix for a chmod issue that's been around since the beginning...

Intel Core Ultra "Meteor Lake" Yields Faster Performance With Linux 6.9

28 mars 2024 à 15:10
While Intel Core Ultra "Meteor Lake" has been working out well under Linux already -- especially with regards to the enticing integrated Arc Graphics -- with the in-development Linux 6.9 kernel it's looking even better for the CPU performance. Here are some initial benchmarks looking at the Intel Core Ultra 7 155H Meteor Lake performance with Linux 6.8 vs. 6.9 Git.

More Efficient VirtIO DRM Driver To Import Scanout Buffers From Other Devices

28 mars 2024 à 10:47
Patches posted today by an Intel engineer allow for importing scanout buffers from other devices with the VirtIO DRM driver that is used in the virtualization space. The importing of scanout buffers from other devices/drivers can allow for more efficient use by avoiding excess copies...

Reverse-Engineered Rockchip NPU Driver Hitting Same Performance As Proprietary Driver

28 mars 2024 à 10:16
Open-source developer Tomeu Vizoso recently began the effort of creating an open-source, reverse-engineered driver for the Rockchip NPU found in some of the latest Rockchip SoCs. After succeeding at open-source NPU driver support for the VeriSilicon NPU IP, Vizoso took up the challenge of working on Rockchip NPU support. With his open-source user-space driver he's already got his first model running. Not only is it running but it's doing so at similar performance to the proprietary driver...

Google Cloud's C3D Instances Provide Strong Performance Value For PingCAP's TiDB

28 mars 2024 à 09:00
Some time ago I ran through a number of benchmarks of Google Cloud's C3D VMs powered by AMD EPYC Genoa processors. The AMD EPYC 9004 series showed terrific performance with strong generational improvements over the Intel Xeon Scalable processors. Following that a request came in to examine the PingCAP TiDB database performance given its growing popularity. In this article we'll review those benchmarks showing how GCE C3D delivers strong performance advantages for TiDB.

Pop!_OS Upgrades To The Linux 6.8 Kernel

27 mars 2024 à 21:00
Besides its desktop-level customizations, further differentiating System76's Pop!_OS Linux distribution from its Ubuntu LTS package base is the tendency to roll down newer versions of the upstream Linux kernel once validated across System76's portfolio of laptops and desktops. The latest on that front is Pop!_OS now shipping with the fresh Linux 6.8 stable series...

SDL3 Will Keep Wayland Default At Least For The Time Being

27 mars 2024 à 16:13
Following several days of discussions from both sides of the table over whether SDL 3.0 should revert its Wayland over X11 preference in light of some aspects of the Wayland ecosystem support not being in good shape, for now at least SDL 3.0 is sticking to the Wayland support by default. It may be revisited though closer to release to see how the upstream support is for users of this hardware/software abstraction library widely used by cross-platform games...

Canonical Continues Exploring Ubuntu x86-64-v3 Images - Now In Microsoft's Cloud

27 mars 2024 à 15:29
Ubuntu maker Canonical has spent the past several months exploring Ubuntu x86-64-v3 based images for leveraging the x86_64 micro-architecture feature level capabilities to target the level embracing AVX/AVX2, FMA, BMI2, and other instructions supported largely since Intel Haswell and AMD Excavator era processors. As shown in benchmarks Ubuntu x86-64-v3 builds can deliver better performance for the AMD/Intel systems of the past number of years. Canonical's latest foray in this area is offering up Microsoft Azure images that are tailored for x86-64-v3...

Blender 4.1 Benchmarks Confirm Even Faster CPU Render Times Under Linux

27 mars 2024 à 14:38
Blender has long enjoyed faster CPU rendering under Linux compared to using Microsoft Windows. Across many different processors over the years consistently we see faster Linux CPU render performance than under Windows, though that's typically the case for most renderers. With yesterday's release of Blender 4.1, there is even faster Linux CPU render speeds. Here are some initial Blender 4.0 vs. 4.1 benchmarks...
