Trying DragonFlyBSD & FreeBSD On The Intel Core i9 9900K With ASUS PRIME Z390-A

Since last month's Intel Core i9 9900K launch for this eight core / sixteen thread processor we have explored its performance for Linux gaming, how the performance and power efficiency go from the Intel 990X to 9900K, the Spectre mitigation costs, and the Intel Coffeelake Refresh performance across various Linux distributions. For those curious about using the new Intel CPUs and Z390 motherboards with one of the BSD operating systems, I spent a few days over the weekend trying out FreeBSD and DragonFlyBSD releases with the i9-9900K and ASUS PRIME Z390-A motherboard combination.

NVIDIA Working On An EGLStreams Back-End For KDE On Wayland

With no recent activity on the NVIDIA-led Unix device memory allocation work that all developer communities could get behind to supersede GBM and EGLStreams for use by Wayland compositors, NVIDIA is working on an EGLStreams back-end for KDE's KWin compositor.

Wine 3.0.4 Is En Route With New Icons, Dozens Of Bug Fixes

Wine 4.0 should be out in early 2019 as the next major stable release of this increasingly used software for running Windows games and applications on Linux and other operating systems. For those not riding the bi-weekly development releases that lead up to the eventual Wine 4.0, Wine 3.0.4 is coming in the days ahead as the latest stable point revision.

Debian Packages To Eliminate Vendor-Specific Patches, Affecting Downstreams Like Ubuntu

Debian packages have supported the concept of vendor-specific patches whereby when DPKG unpacks a source package on different operating systems / distributions (such as Debian vs. Ubuntu), different patches could be selectively applied. Ubuntu is one of the main benefactors of this feature while effective immediately these vendor-specific patches to source packages will be treated as a bug and will be unpermitted following the Debian 10 "Buster" release.

A Look At The GCC 9 Performance On Intel Skylake Against GCC 8, LLVM Clang 7/8

With GCC 9 embarking upon its third stage of development where the focus ships to working on bug/regression fixes in preparation for releasing the GCC 9.1 stable compiler likely around the end of Q1'2019, here is a fresh look at the GCC 9 performance with its latest development code as of this week compared to GCC 8.2.0 stable while using an Intel Core i9 7980XE test system running Ubuntu Linux. For good measure are also fresh results from LLVM Clang 7.0 stable as well as LLVM Clang 8.0 SVN for the latest development state of that competing C/C++ open-source compiler.

Mesa Gets Testing Patches For New Zen Optimization Around Thread Pinning

It was just yesterday that the AMD Zen L3 thread pinning was dropped from Mesa due to that optimization not panning out as intended for benefiting the new AMD processors with the open-source Linux graphics driver stack. Lead Mesa hacker Marek Olšák is already out with a new Zen tuning implementation that may deliver on the original optimization goal.

Systemd-Free, XBPS-Powered Void Linux Releases New Images

If you are looking for a new Linux distribution to experiment with, Void Linux is one of the interesting ones that is an original creation and community driven that often doesn't receive the attention it deserves. Void Linux is built off its BSD-licensed XBPS packaging system, is a rolling-release platform, uses runit as the init system instead of systemd, opts for LibreSSL in place of OpenSSL, optional musl libc usage, and has a wealth of other changes.

16-Way AMD EPYC Cloud Benchmark Comparison: Amazon EC2 vs. SkySilk vs. Packet

With last week Amazon Web Services rolling out AMD EPYC cloud instances to EC2, I figured it would be an interesting time for a fresh benchmark look at how the AMD Linux cloud performance compares from some of the popular cloud providers. For this article are sixteen different instances benchmarked while looking at the raw performance as well as the value on each instance type relative to the benchmark performance and time consumed for the on-demand spot instancing. EPYC instances were tested from Amazon EC2, Packet.com, and SkySilk.

Kernel Developers Debate Having An Official Linux System Wrapper Library

As new system calls get added to the Linux kernel, these syscalls generally get added to Glibc (and other libc libraries) for developers to make easy use of them from their applications. But as Glibc doesn't provide 1:1 coverage of system calls, sometimes is delayed in their support for new calls, and other factors, there is a discussion about providing an official Linux system wrapper library that could potentially live as part of the kernel source tree.

AMDVLK Vulkan Driver Sees Its First Tagged Release

In the nearly one year that the AMDVLK official Vulkan driver has been open-source there hasn't been any "releases" but rather new code drops on a weekly basis that is pushed out of their internal development repositories. But surprisingly this morning is now a v2018.4.1 release tag for this open-source AMD Vulkan Linux driver.

The Performance Impact Of Spectre Mitigation On POWER9

Over the past year we have looked extensively at the performance impact of Spectre mitigations on x86_64 CPUs but now with having the Raptor Talos II in our labs, here are some benchmarks to see the performance impact of IBM's varying levels of Spectre mitigation for POWER9.

Gallium D3D9 "Nine" Support Gets New Patches To Help Fight Lag Without Tearing

While most Linux gamers these days are mesmerized by DXVK for mapping Direct3D 10/11 to Vulkan for better handling Windows games on Linux, for those with older Direct3D 9 era games there is still the Gallium Nine initiative for D3D9 implemented as a Mesa Gallium state tracker. A new patch series posted this weekend will make that Gallium Nine experience even better.

POWER On-Chip Controller Driver Coming For Linux 4.21

The IBM POWER On-Chip Controller (OCC) driver is queued for inclusion in the next version of the Linux kernel. This on-chip controller driver collects sensor data from the system and processor, including temperature and power metrics, and exposes that to the user as well as handling thermal/power management tasks.
