Intel announced at the end of April the 10th Gen Core "Comet Lake" S-Series CPUs with the Core i9 10900K being their new top-end processor with a 10 core / 20 thread processor that can clock up to 5.3GHz. The Comet Lake S-Series desktop CPUs are now shipping and this morning the embargo lifts in being able to publish the benchmarks. Here is how the Intel Core i5 10500K and Core i9 10900K processors are performing on Linux from Steam on Linux gaming to various interesting real-world workloads.

On Tuesday was the big announcement of Microsoft bringing Direct3D 12 to Linux/WSL2 in the context of allowing GUI applications and GPU compute within Windows Subsystem for Linux. This also means OpenCL/OpenGL/Vulkan support by ultimately converting it into D3D12 consumption by the host Windows system. While Microsoft was quick to post patches for their "dxgkrnl" kernel driver for this Direct3D implementation, it's already facing resistance and will be an uphill battle for it to be mainlined...

This is the Intel feature for helping prevent ROP and COP/JOP style attacks via indirect branch tracking and a shadow stack. Recently there has been a fair amount of CET improvements to the various open-source components...

While there aren't yet any Arm SoCs we are aware of at least offering Thunderbolt connectivity, that will eventually change with at least USB4 being based on Thunderbolt. But in any case Thunderbolt software support can work on Arm today if using a Thunderbolt add-in PCIe card...

Since last year's GCC 9 release the C++17 support has been considered stable and with the changeover to it as the default C++ dialect having not happened for the recent GCC 10 release, developers are now looking at increasing the default C++ version to 17 for next year's GCC 11 release...

Several days back was the proposal to "remove AGP support" from Radeon/Nouveau/TTM. This did formulate into a set of patches that would disable the AGP mode in the Radeon driver and deprecate the AGP code in TTM memory management. However, as was pointed out in the ensuing discussion, AGP graphics cards will still be operable on Linux with this level of deprecation by using the PCI GART mode...

This week I began benchmarking the AMD Ryzen 7 4700U on Linux using the new Lenovo IdeaPad featuring this new Zen 2 "Renoir" APU.

One of the long sought after features for AMD Zen (and Zen 2) processors on Linux has been the ability to monitor the CPU package power consumption on Linux, similar to what's long been available for Intel CPUs on Linux and similarly for older AMD Bulldozer era CPUs with a power monitoring driver. Now on Friday evening a patch series was posted by a Google engineer to provide this long sought after functionality...

Two days ago as part of the GPUOpen relaunch AMD released Radeon Rays 4.0 as their ray intersection library.
