  • Open-Source NVIDIA/Nouveau Changes Submitted For Linux 5.8

    There hasn't been too much to report on the open-source NVIDIA "Nouveau" kernel driver in some time since the enabling of Turing and no apparent progress on re-clocking to allow the graphics cards to hit their rated clock frequencies (the longstanding, number one limitation for this open-source driver), but some changes were sent in today for the upcoming Linux 5.8 kernel merge window.

  • Linux 5.8 Set To Optionally Flush The L1d Cache On Context Switch To Increase Security

    The Linux kernel patches that have been spearheaded by Amazon AWS engineers to optionally flush the L1 data cache on each context switch have now been queued in the x86/mm branch ahead of the upcoming Linux 5.8 kernel cycle.

    This L1d cache flushing on context switches is being done in light of the various CPU security issues that have come to light in recent times and acknowledging there are likely other yet to be discovered vulnerabilities. Flushing the L1d cache on context switches helps fend off data from being snooped or leaked via side channels.

  • Linux 5.8 To See Support For POWER10's Prefixed Instructions

    Beyond the usual excitement of numerous x86 and Arm hardware advancements each cycle, Linux 5.8 is bringing new IBM POWER enablement work.

    Recently there has been an uptick in open-source/Linux enablement work for the forthcoming POWER10 and that holds true for Linux 5.8. There has been a patch series going around recently for introducing prefixed instruction support on the POWER front for a "future revision of the ISA." That work is now ready and queued ahead of the Linux 5.8 cycle opening up in early June.

Games: Oxygen Not Included, Proton, GDScript

  • The first DLC for Oxygen Not Included sounds huge, free update soon too

    Klei Entertainment have been busy working behind the scenes on the next free update and first expansion for Oxygen Not Included and they've detailed what's coming. First, the free update coming within the next few days should fix plenty of issues, including one involving infinite digging which sounds annoying. More exciting is the DLC though, it's sounding like it's going to be massive!

  • VKD3D-Proton is the new official Direct3D 12 to Vulkan layer for Proton

    VKD3D was originally a project created directly by the Wine team, the compatibility layer that Proton is built upon. However, the original founder passed away and it seems Valve-funded developers are taking the torch to push it much further. It's actually been a thing for a while but today they adjusted the name of their project as VKD3D-Proton, to give it some official status plus preventing any naming conflicts elsewhere and just be clear about their goals. They're going for supporting the "full" Direct3D 12 API on top of Vulkan, with an aim of both performance and compatibility using modern Vulkan extensions and features, so this comes at the expense of compatibility with older drivers and GPUs. They're also not looking to keep backwards compatibility with the original vkd3d.

  • GDScript progress report: Type checking is back

    After completing the new tokenizer and parser as mentioned in the previous reports, I started working on the code analyzer, which is responsible for type checking and also for used for other features like warnings and some optimizations. This was done before as a second pass inside the parser but it was now moved to another class to make it clear that it doesn't happen at the same pass thus avoiding issues with functions being called out of order (which happened by a few contributions that missed this detail).
