Continuing on with all of the OpenCL Mesa work that's been going on by Red Hat developers in recent time, LLVM's libclc library now has support for targeting Mesa SPIR-V.

The new target added to LLVM's libclc is for emitting SPIR-V geared for Mesa's OpenCL support. Libclc is the LLVM sub-project focused on providing a library for OpenCL C run-time usage. Existing targets have included AMDGPU/AMDGN, R600, and NVIDIA NVPTX while SPIR-

Edward Shishkin continues pushing ahead with not only maintaining the existing out-of-tree Reiser4 file-system code but also developing Reiser5 seemingly without any major corporate support. Reiser4 and the experimental Reiser5 file-system code were updated on Monday for Linux 5.8 kernel compatibility.

The Reiser4 kernel driver along with the unstable Reiser5 kernel code saw new patch releases for supporting them on the Linux 5.8 stable kernel (Linux 5.8.1 target to be exact).

Besides re

It landed sooner than anticipated but the LLVMpipe patches enabling OpenGL 4.5 support were merged to Mesa 20.3-devel today and are also marked for back-porting to the Mesa 20.2 series soon to be promoted to stable.

The Mesa 20.2 feature code was already set to take this software-based OpenGL driver from GL 3.3 to GL 4.3 after all the work carried out by Red Hat's David Airlie in recent months. But now his work on

While Raptor Computing Systems has been making fabulous 100% open-source/libre hardware systems based around POWER9 with the likes of their Talos II and Blackbird systems, don't hold your breath on quickly seeing fully-open POWER10 systems even with "OpenPOWER" being trumpeted in recent years and similar for being more open-source friendly than the likes of Intel and AMD.

IBM today announced POWER10 for shipping in H2'2021 . But as mentioned in that article

SiFive today announced OpenFive as their custom silicon business now spun into its own self-contained, autonomous unit.

While SiFive is most known for their RISC-V architecture designs, SiFive's OpenFive isn't limiting their custom silicon development to RISC-V but also supports Arm and other CPU ISAs for embracing heterogeneous mixed-ISA designs.

OpenFive is being promoted as ISA-neutral and RISC-V agnostic and will work with customers for AI, edge computing, HPC, and other workloads.

Red Hat's David Airlie has been on quite a spree lately with open-source graphics driver improvements from OpenGL 4 for LLVMpipe to now merging "VALLIUM" for a Vulkan software implementation.

VALLIUM has come together in the past several months as a software/CPU-based Vulkan driver based on LLVMpipe . Airlie has been developing it on his own Mesa branch while today it was merged into Mesa 20.3-devel.

Before getting too excited, of the initial merge he commented, " This is the initial

Version 20.08 of Kdenlive has been released, the KDE-aligned open-source non-linear video editor platform that is among the best in the field for open-source, community-driven projects.

Kdenlive 20.08 brings multiple audio stream support, new interface layouts, crash fixes, improved cache management handling, new keyboard shortcuts, and various other user-interface improvements.

Open-source video editors still largely struggle to compete with the commercial/proprietary offerings, but Kdenlive has matured

After covering the Linux/open-source POWER10 bring-up for a number of months already, IBM has finally announced firm information on their forthcoming POWER10 processors. POWER10 looks promising but these 7nm CPUs will not begin shipping until the second half of next year.

Among the information published by IBM today pertaining to POWER10 includes:

- POWER10 is to be manufactured on a 7nm process, as expected.

- Up to 3x greater processor energy efficiency, workload capacity
