Here is an up-to-date look at how the very latest Mesa 20.1 Git performance is for the Radeon "RADV" Vulkan driver both out-of-the-box and when enabling the Valve-backed ACO compiler back-end alternative to AMDGPU LLVM. Plus there are benchmarks of the latest AMDVLK open-source AMD Vulkan driver and also when using AMDGPU-PRO's Vulkan packages that still rely upon AMD's proprietary shader compiler.

While many would argue it's past due for the Linux kernel's floppy disk code to be gutted from the mainline code-base, instead it's seeing improvements in 2020 ahead of the Linux 5.7 kernel... The same kernel where Intel stabilized Tiger Lake graphics, AMD preparing Zen 3 support, a new exFAT driver, and a multitude of other modern improvements is also now seeing floppy work...

While a lot of feature work has been building up for Linux 5.7 in various subsystem development repositories ahead of the merge window in a few weeks, one of the big driver additions many users have been clamoring for isn't yet queued. The AMD Sensor Fusion Hub open-source driver for Linux appears stalled pending more reviews from upstream developers...
Flying under our radar until now was that KDE Frameworks 5.68 was released last week as the monthly update to this collection of KDE-minded libraries complementing the Qt tool-kit...

Back in January "iGPU Leak" was disclosed as CVE-2019-14615 as an information leakage vulnerability affecting Intel's graphics architecture leading to both register and local memory leaks. While Intel "Gen9" graphics were patched right away on the disclosure date and Gen8 Broadwell graphics were already mitigated, Gen7/Gen7.5 graphics took longer... In fact, not until the Linux 5.7 release this spring is there the mitigation for iGPU Leak...
It's been a while since having news on Redox OS as the Rustlang-written open-source operating system. But it turns out that's been due to Jeremy Soller being busy working on Pkgar as a new package management format for the operating system...
Over the past year we have seen a steady flow of Intel Tiger Lake "Gen12" graphics enablement for the Linux kernel, their first generation also adopting the Xe Graphics branding as part of their discrete GPU initiative. With the Linux 5.7 kernel this spring will be the first release where the Gen12 graphics support is there by default as a sign of stability...
Hot off yesterday's release of Wine 5.4 with Unicode 13 and text drawing for D3DX9, Wine-Staging 5.4 is now available with more than 850 patches on top of it...
Any regular Phoronix reader should already be quite familiar with SVT-AV1 and the other open-source Scalable Video Technology encoders considering how much we have been benchmarking them -- months before even before they were officially announced. Netflix, which has been working on SVT-AV1 in conjunction with Intel, has an interesting write-up for some weekend reading on the state of this open-source AV1 encoder/decoder...
Microsoft announced in their forthcoming Windows 10 Version 2004 update that Windows Subsystem for Linux 2 (WSL2) will be entering general availability status...

Currently the Linux kernel SECCOMP secure computing mode force-enables Spectre protections, which comes with obvious performance implications. When force-enabled, however, processes can't opt-out of the protection if they are not at risk to the likes of Spectre V4 "Speculative Store Bypass" issues. But a simple change being proposed would let such processes opt out if desired...
2020 could be the year we see the Vulkan API seeing more adoption on the desktop outside of games. We are already looking forward to LibreOffice 7.0 with Vulkan rendering support coming out later this summer while the next FFmpeg release also has Vulkan support lined up...
There have not been many AMDVLK open-source AMD Radeon Vulkan driver releases this quarter, but out today in any case is AMDVLK 2020.Q1.3 as their newest update to this official open-source Vulkan driver derived in part from shared sources with the AMD Vulkan Windows driver...
One of the most frequent critiques of Intel's Clear Linux distribution has been its lackluster support in dealing with proprietary/third-party packages like the Google Chrome web browser and Valve's Steam gaming client. Since last summer, Clear Linux has been working on their third-party packaging support with their unique "bundles" system, but not much has been heard on the matter since...
Feature work of Direct Rendering Manager (DRM) graphics driver work for Linux 5.7 is winding down now that Linux 5.6 is almost to its sixth release candidate this weekend, but sent in this week by AMD were a few more AMDGPU items though mostly amounting to fixes for their graphics driver...
In addition to WebAssembly's growing presence outside of the web browser thanks to various desktop run-times and interesting use-cases, WebAssembly is also popping up in other areas. Google has been working on WebAssembly support for extensions within network proxies typically reserved for C/C++ or the likes of Lua scripts...
On Tuesday the Load Value Injection (LVI) attack was disclosed by Intel and security researchers as a new class of transient-execution attacks and could lead to injecting data into a victim program and in turn stealing data, including from within SGX enclaves. While Intel has publicly stated they don't believe the LVI attack to be practical, one of their open-source compiler wizards did go ahead and add mitigation options to the GNU Assembler as part of the GCC toolchain. Here are benchmarks showing the performance impact of enabling those new LVI mitigation options and the significant impact they can cause on run-time performance in real-world workloads.
