With the tests earlier this week of the 16-way AMD EPYC cloud comparison the real standout of those tests across Amazon EC2, Packet, and SkySilk was Packet's bare metal cloud. For just $1.00 USD per hour it's possible to have bare metal access to an AMD EPYC 7401P 24-core / 48-thread server that offers incredible value compared to the other public cloud options for on-demand pricing. That led me to running some more benchmarks of Packet.com's other bare metal cloud options to see how the Intel Xeon and AMD EPYC options compare.

The RadeonSI OpenGL driver offered Vega primitive binning support the past year followed by the RADV Vulkan driver, but it hadn't been enabled by default. Those working on the RADV driver are now planning on unconditionally enabling this Vega performance optimization for up to a few percent performance boost...

It's now been nearly one year since longtime Nouveau contributor Karol Herbst joined Red Hat where one of his big projects has been working on OpenCL support for this open-source NVIDIA driver by bringing up NIR/SPIR-V support and making the necessary improvements for allowing OpenCL kernels to be represented in that IR commonly used by the Mesa drivers. The work still isn't yet in Mesa Git, but Karol this week sent out his newest patches...

PHP developers unanimously approved and already merged support for the new "preloading" concept for this web server language. PHP preloading basically allows loading PHP code that persists as long as the web server is running and that code will always be ready for each subsequent web request, which in some cases will dramatically speed-up the PHP performance on web servers...

The recent release of Fedora 29 the long-desired goal of a flicker-free boot experience to the Linux desktop was finally achieved... Well, assuming you are for now using Intel graphics and set a couple extra settings and don't have any quirky hardware. While all of the key components are in place, for Fedora 30 and beyond they will likely be taking care of the "rough edges" and already there is work on a new Plymouth boot theme for pairing with this flicker-free boot process...

The "AMDGPU" Radeon Linux kernel graphics driver is preparing support for "Adaptive Backlight Management" as a backlight power-savings feature for laptops...

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...

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.

Ubuntu 19.04 "Disco Dingo" development is now officially underway...

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...

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...

With Feral Interactive preparing to release Total War: WARHAMMER II for Linux and macOS later this month, today they announced the system requirements for this latest native game port...

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.

Vulkan 1.1.92 is out today to mark the newest specification update to this high-performance graphics/compute API...

While Microsoft is self-proclaimed to love Linux, their common and very basic Microsoft OEM Mouse has not loved the Linux kernel or vice-versa... The Linux kernel HID code is finally getting a quirk fix to deal with the Microsoft OEM mouse as it would disconnect every minute when running at run-levels one or three...

Back in September Code Sourcery / Mentor Graphics posted their new Radeon GCN port for the GNU Compiler Collection (GCC). Two months later this port is still being worked on but not yet ready for mainline...

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...

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 Linux kernel will likely be doing away with EXOFS, a file-system that had been around since the Linux 2.6.30 days...
