Open-Source C.A.S. Vulkan Layer - Similar to Radeon Image Sharpening But For Any GPU

AMD's Radeon Image Sharpening feature is designed to improve image quality with minimal performance costs. However, it is only supported by Radeon Polaris / Vega / Navi graphics cards and only under Microsoft Windows 10. An independent open-source project has implemented contrast adaptive sharpening support for Vulkan that is similar to Radeon Image Sharpening but will work for any Vulkan-enabled GPU -- including NVIDIA GPUs.

Codeplay Launches Open-Source 'SYCL Academy' To Learn This Increasingly Popular Standard

While SYCL has been around for five years as a Khronos standard providing a single-source C++ programming model for exploiting OpenCL, it has yet to reach its prime but demand for it is picking up with Intel working to upstream their SYCL back-end in LLVM, SYCL becoming part of their programming model with oneAPI and Xe Graphics, and other vendors also jumping on the SYCL bandwagon. Codeplay has now provided an open-source SYCL learning code for those interested in this higher-level alternative to straight OpenCL programming.

Intel's Cloud Hypervisor 0.3 Adds Block Device Offloading, Paravirtualized IOMMU

Intel developers have been working on the Cloud Hypervisor that is written in Rust and built atop KVM as an open-source VMM designed for running modern cloud workloads while being focused on just supporting modern software/interfaces and relying upon para-virtualized (VirtIO) devices without legacy support. This week marked a new release of this forward-looking KVM-based hypervisor solution.

Paragon Looks To Upstream Their Microsoft exFAT Driver For The Linux Kernel

With the upcoming Linux 5.4 kernel release there is now an exFAT file-system driver based on an old Samsung code drop of their exFAT driver support for mobile devices. This comes after Microsoft made the exFAT specification public recently and gave their blessing for a native Linux driver for the file-system. The Linux developers acknowledge though the current exFAT code is "horrible" and a "pile of crap" but is within the staging area.

AMD EPYC vs. Intel Xeon Cascadelake With Facebook's RocksDB Database

Following the benchmarks earlier this month looking at PostgreSQL 12.0 on AMD EPYC Rome versus Intel Xeon Cascade Lake there was interest from Phoronix readers in wondering how well Rome is doing for other modern enterprise database workloads. One of those workloads that was recently added to the Phoronix Test Suite / OpenBenchmarking.org is Facebook's RocksDB, the company's embedded database that is forked from Google LevelDB. With RocksDB being designed to exploit many CPU cores and modern SSD storage, here are some benchmarks looking at how the Xeon Platinum 8280 stacks up against various new AMD EPYC 7002 series processors.

GhostBSD Reaffirms To Being TrueOS+BSD Desktop OS With Official MATE Desktop

With Project Trident moving away from a TrueOS/FreeBSD base to instead Void Linux, if you are looking for a good BSD-based desktop operating system it largely comes down to the likes of MidnightBSD and GhostBSD providing good out-of-the-box setups. As for GhostBSD, they are reaffirming their commitment to using TrueOS/FreeBSD and MATE as their official desktop.

A Vast Majority Of Linux's Input Improvements Are Developed By One Individual

While there is an ever increasing number of open-source developers focusing on the Linux graphics stack with the GPU drivers and related infrastructure, it's quite a different story when it comes to the Linux input side. It's basically one developer that has been working on the Linux input improvements for the past number of years.

LLVM Clang RISC-V Now Supports LTO

With the recent release of LLVM 9.0 the RISC-V back-end was promoted from an experimental CPU back-end to being made "official" for this royalty-free CPU ISA. Work though isn't over on the LLVM RISC-V support with new features continuing to land, like link-time optimizations (LTO) most recently being enabled within the Clang 10 code.
