Submission + - Intel starts publishing open-source Linux driver code for discrete GPUs (phoronix.com)

Submitted by fstack
fstack writes: Intel is still a year out from releasing their first discrete graphics processors, but the company has begun publishing their open-source Linux GPU driver code. This week they began by publishing patches on top of their existing Intel Linux driver for supporting device local memory for dedicated video memory as part of their restructuring effort to support discrete graphics cards. Intel later confirmed this is the start of their open-source driver support for discrete graphics solutions. They have also begun working on Linux driver support for Adaptive-Sync and better reset recovery.

Submission + - The Combined Impact Of Spectre/Meltdown/Foreshadow With Intel Xeon v. AMD EPYC (phoronix.com)

Submitted by Anonymous Coward
An anonymous reader writes: Using the newly minted Linux 4.19 feature code, fresh benchmarks were carried out looking at the performance cost of Spectre / Meltdown / Foreshadow mitigations on Intel Xeon v. AMD EPYC CPUs. Workloads affected by these CPU vulnerabilities mainly deal with I/O and frequent kernel calls while CPU bound tests are still found to be minimally impacted. When toggling these mitigations on Linux 4.19, Intel Xeon CPUs were found to be 10~15% slower with the default kernel while AMD EPYC CPUs dropped to about 5% slower. While a setback in performance, even with Intel's losses, the raw performance was still ahead in the tested Xeon processors.

What does this "pretty big release" offer? Phoronix's Linux 4.19 feature overview sheds light on more Spectre CPU mitigations for x86/POWER/s390, the new EROFS read-only Android file-system, a Raspberry Pi voltage driver, ThinkPad calculator key support, an in-kernel GPS subsystem, the Google GASKET driver framework, virtual kernel mode-setting, Qualcomm Adreno 600 series support, and many other improvements.

Submission + - Linux 4.18 Preparing Many New Features While Dropping 100k+ Lines Of Code (phoronix.com)

Submitted by Anonymous Coward
An anonymous reader writes: Linux 4.18 development is going strong with today's 4.18-rc1 release. This kernel cycle has dropped 107,210 lines of code so far but Linux 4.18 is adding many new features. The kernel is coming in lighter as a result of the LustreFS code being removed and other code cleanups. On the feature front, Phoronix reports, "ew AMDGPU support improvements, mainlining of the V3D DRM driver, initial open-source work on NVIDIA Volta GV100 hardware, merging of the Valve Steam Controller kernel driver, merging of the BPFILTER framework, ARM Spectre mitigation work, Speck file-system encryption support, removal of the Lustre file-system, the exciting restartable sequences system call was merged, the new DM writecache target, and much more."

Submission + - Ubuntu Considering An HTML5-Based OS Installer (phoronix.com)

Submitted by Anonymous Coward
An anonymous reader writes: Ubuntu's Self-Appointed Benevolent Dictator for Life, Mark Shuttleworth, is considering backing a new Ubuntu installer that would be using HTML5 via the Electron Framework. This theoretical installer would re-use the company's existing HTML5 code for managing MAAS installations, integrate with Electron, and also better support their Snap packaging format, according to his proposal. What could possibly go wrong with an HTML5/Electron operating system installer? Mark also announced that Ubuntu 18.10 is codenamed the Cosmic Cuttlefish.

Submission + - Raspberry Pi 3 B+ Benchmarks Show Much Nicer Performance (phoronix.com)

Submitted by fstack
fstack writes: Pi Day was marked this year by the launch of the Raspberry Pi 3 Model B+ as the next evolution to this $35 ARM single-board computer. Phoronix has now put out Raspberry Pi 3 B+ benchmarks showing that the Ethernet performance is indeed much faster now but still doesn't stack up to other high performance boards, the SoC temperature is noticeably lower than the very warm Raspberry Pi 3, and the overall performance is a nice upgrade while retaining the same price point as its predecessors. Follow up tests looking at the WiFi performance also show the new 802.11ac dual-band wireless to be much faster as well.

Submission + - Ubuntu 18.04 Switching Back To X.Org From Wayland (phoronix.com)

Submitted by Anonymous Coward
An anonymous reader writes: Five years after their original goal to ship Ubuntu with Wayland, Ubuntu 17.10 transitioned to using the Wayland display system by default as part of their transition to GNOME Shell as the default desktop. But with the upcoming Ubuntu 18.04 LTS release, Canonical has decided to transition back to the X.Org Server. Their reasoning for moving to an X.Org Server by default is better support for screen sharing, remote desktop, and better recovery from crashes. But for those interested the Wayland session will still be available as a log-in option.

Submission + - AMD Open-Sourcing Their Official Vulkan Linux Driver (phoronix.com)

Submitted by Anonymous Coward
An anonymous reader writes: While many of you have likely heard of the "RADV" open-source Vulkan driver, it's been a community-written driver up to this point in the absence of AMD's official, cross-platform Vulkan driver being open-source. That's now changed with AMD now open-sourcing their official Vulkan driver. The code drop is imminent and they are encouraging the use of it for quick support of new AMD hardware, access to the Radeon GPU Profiler, easy integration of AMD Vulkan extensions, and enabling third-party extensions. For now at least it does provide better Vulkan performance than RADV but the RADV developers have indicated they plan to continue development of their Mesa-based Vulkan driver.

Submission + - Intel Shows How To Build A Powerful OS With Clear Linux (phoronix.com)

Submitted by Anonymous Coward
An anonymous reader writes: Recently completed Linux distribution benchmarks by Phoronix show that Intel's Clear Linux to be the most powerful on x86 hardware. A six-way enterprise focused Linux distribution comparison show Clear Linux being the fastest with a Core i9 and Xeon systems, easily beating CentOS, openSUSE, and Ubuntu in a majority of the tests. When doing an 11-way Linux distro boot test they also found Clear Linux easily booted the fastest followed by the Clear-inspired Solus distribution. Clear Linux does work on AMD hardware and works on Intel CPUs back to Sandy Bridge but leverages its speed from optimized compiler settings, specially built libraries capable of AVX instructions on supported systems, a specially tuned kernel configuration, and other optimizations/patches.
