With the new security mitigation for the "Native BHI" Spectre vulnerability affecting even the recent Intel processors, a number of Phoronix readers have been curious about the performance impact of the mitigation. Over the past week I've been running some benchmarks on recent Intel CPUs to better look into any performance implications.

Intel's software team is today sharing their newest innovation for achieving greater performance on Linux systems: the Thin Layout Optimizer. Intel's Thin Layout Optimizer is inspired by the likes of the Meta/LLVM BOLT optimizer and Google's Propeller but aims to be much easier to use while still delivering measurable performance gains for optimized binaries.

The turbostat utility is useful on Linux systems for reporting idle/power-state statistics, temperatures, and other useful metrics for modern CPUs. It's also able to dive deeper and provide various MSR values and counters and other intriguing CPU bits. For much of these features root access is required and thus turbostat has bailed out up to this point if not running as root. But as a number of the metrics can still be obtained without root access, turbostat is finally being adapted to handle running better as a non-root user.

Intel's FFmpeg Cartwheel is where they maintain their various yet-to-be-upstreamed patches for the FFmpeg multimedia library either to enhance/enable new Intel graphics hardware support or improve/add extra functionality to this widely-used open-source library. With the Intel FFmpeg Cartwheel 2024Q1 release they are shipping a new filter for dealing with older content as well as several other new features.

The Xe kernel driver targets Tigerlake graphics and newer while it won't be until Lunar Lake / Xe2 when it aims to become the default driver for Intel iGPU/dGPU graphics. For the upcoming Linux 6.9 kernel merge window are more feature changes and fixes to this new open-source Intel kernel graphics driver.

The Linux kernel has supported the Intel Hardware Feedback Interface "HFI" via the "intel_hfi" driver since 2022 for bettering supporting Core hybrid processors. The Intel HFI can be used for communicating performance and energy efficiency capabilities of individual CPU cores of the system. In turn the Linux kernel can leverage Intel HFI details for better task placement among the available CPU cores/threads. With a new patch series, the Intel HFI driver can "save tons of CPU cycles" by only enabling it when needed.

Intel confirmed at their MWC 2024 briefings that Granite Rapids D will debut in 2025 as the successor to Ice Lake D for Xeon D edge processors.

Sent in this morning via the "x86/urgent" pull request ahead of the Linux 6.8-rc6 kernel later today is a set of patches from Intel to ensure clearing of CPU buffers using the VERW instruction happens at the latest possible point in the return-to-userspace code path. This is being done to better protect against CPU bugs like Microarchitectural Data Sampling (MDS).
