Linus Torvalds Comments On STIBP & He's Not Happy - STIBP Default Will End Up Changing

It turns out that Linus Torvalds himself was even taken by surprise with the performance hit we've outlined on Linux 4.20 as a result of STIBP "Single Thread Indirect Branch Predictors" introduction as well as back-porting already to stable series for cross-hyperthread Spectre V2 protection. He doesn't want this enabled in full by default.

Building The Linux Kernel With Clang Is Becoming Popular Again

Years ago there was much interest in the ability to build the mainline Linux kernel with the LLVM Clang compiler as an alternative to using the GCC compiler in order to ensure better code portability, shaking out GCC'isms, possible build speed improvements, and other benefits. But in recent years it seems to have waned in interest but now things are heating up again.

To No Surprise, Intel's Discrete GPU Efforts Will Support Linux Gaming

It should come as virtually no surprise to any regular Phoronix reader given the significant investment Intel makes to Linux via their Open-Source Technology Center with working on Mesa for their Vulkan/OpenGL drivers and related components, but their discrete GPU undertaking will support Linux gaming alongside Windows.

Intel Working On Open-Sourcing The FSP - Would Be Huge Win For Coreboot & Security

Intel's Architecture Day on Tuesday was delightfully filled with an overwhelming amount of valuable hardware information, but Intel's software efforts were also briefly touched on too. In fact, Raja Koduri reinforced how software is a big part of Intel technology and goes in-hand with their security, interconnect, memory, architecture, and process pillars and that's where their new oneAPI initiative will fit in. But what learning afterwards was most exciting on the software front.

AMD Adding STIBP "Always-On Preferred Mode" To Linux

Initially during the Linux 4.20 kernel merge window with the STIBP addition for cross-hyperthread Spectre V2 mitigation it was turned on by default for all processes. But that turned out to have a sizable performance hit so the behavior was changed to only turn it on for processes under SECCOMP or when requested via the PRCTL interface. However, AMD is landing a patch that for select CPUs will have an always-on mode as evidently that's preferred for some AMD processors.
