Disclosed by Arm last summer was the Straight Line Speculation (SLS) vulnerability and they were quick to introduce new safeguards against SLS in the GCC and LLVM compilers. The compiler-based mitigations to straight-line speculation involves adding speculation barrier sequences around the vulnerable instructions to prevent speculatively executing instructions around changes in control flow. While compiler developers were quick to add the options, so far the Linux kernel developers are in disagreement still over its importance and the proposed patches that would flip on this option when compiling the ARM Linux kernel...

When it comes to the AMDGPU kernel driver changes in Linux 5.12 for modern open-source AMD Radeon graphics, most notable is RDNA2 OverDrive overclocking support now being available as well as AMDGPU FreeSync over HDMI (pre-HDMI 2.1). But from initial testing the new in-development kernel is showing mostly subtle performance improvements for the Radeon RX 6800 series over Linux 5.11.

Published last month was an updated but still experimental version of the native Wayland support for Wine after that code was originally published last year. One of the lingering questions has been around the prospects of mainlining this Wayland driver in Wine while last week the longtime Wine project leader, Alexandre Julliard, provided some clarity on the matter...

While it's 2021 and many modern Linux gaming and other workloads are focusing on the Vulkan API, Intel isn't letting up in their aggressive optimizations to their open-source "Iris" OpenGL Gallium3D driver for Linux systems. With the latest Mesa 21.1 code today there is a set of patches providing up to 17% better performance in some games while other OpenGL software is generally a few percent faster at least. In some micro-benchmarks it can be more than 50% faster...

Last week I issued a warning of possible data loss on the early Linux 5.12 kernel code that was reliably leaving my test systems severely corrupted. Intel's internal graphics test systems it turns out have now been bitten by this issue in encountering this significant file-system corruption and as such they've been quick to jump on the issue - there's now an idea what's causing the nasty issue and a workaround by reverting select patches...

It's been talked about many times from various parties but so far has remained elusive from the mainline LLVM code-base: a SPIR-V back-end for LLVM that would go from LLVM into this Khronos intermediate representation most notably used by OpenCL and Vulkan drivers. Intel engineers are stepping up and hope to help get a proper SPIR-V back-end upstreamed into LLVM...
