A day after explicit sync support was merged for XWayland, a week after explicit sync support for Mesa Vulkan drivers hit Mesa 24.1, and GNOME's Mutter enabling explicit sync at the end of March, KDE's KWin compositor has now merged its Wayland explicit sync support!..

Mesa's Lavapipe driver as a software (CPU-based) implementation of the Vulkan API has now implemented support for ray-tracing pipelines...

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...

Due to yesterday's Native BHI vulnerability disclosure affecting all Intel processors with this variant of Branch History Injection (BHI) not requiring BPF to exploit, a slew of new Linux kernel stable releases are out today to back-port this security mitigation...

While the Gentoo Foundation has long existed, to reduce the organizational complexity and overhead as well as becoming effectively a tax deductible non-profit at the US federal level, Gentoo Linux has become an associated project with Software in the Public Interest (SPI)...

Following yesterday's news of Canonical launching Ubuntu Pro For Devices, the latest mobile/embedded news in the Ubuntu space this week is Canonical partnering with Qualcomm...

For several years Intel has been developing the OpenCL Intercept Layer to assist in debugging OpenCL software. It's been nearly two years since the last release of this open-source OpenCL interception layer while today brings v3.0.4 with a number of optimizations and new features...

Sent out this morning were a batch of x86 platform driver fixes by Intel engineer and platform-drivers-x86 co-maintainer Ilpo Järvinen. Besides a couple of fixes, worth mentioning is the Intel HID driver seeing support added for upcoming Arrow Lake and Lunar Lake platforms...

Disclosed back in March 2022 was Branch History Injection (BHI) as a new Spectre vulnerability affecting Intel and Arm CPUs. Then in July of 2022 were patches for Intel working on hardware-based prevention for Spectre-BHI attacks. Now two years later the Linux kernel is seeing mitigations added for the native Branch History Injection vulnerability given a new "Native BHI" variant...

Since SiFive ceased production of the HiFive Unleashed developer board we've been clamoring for a new and more powerful RISC-V developer board... Today SiFive announced the HiFive Premier P550 as a new developer system offering that will be available this summer...

Intel is using its Vision 2024 conference in Arizona today to announce the Gaudi 3 AI accelerator. With Gaudi 3 comes some rather bold AI claims from Intel: 50% on average better inference and 40% on average better power efficiency than the NVIDIA H100. All while costing "a fraction" of the NVIDIA H100. Gaudi 3 sounds quite promising and will be interesting to see how its adopted in the marketplace. In addition, Intel also is disclosing the new Xeon 6 branding for their upcoming server processors formerly codenamed Sierra Forest and Granite Rapids.

Similar to Amazon AWS and Microsoft Azure spinning their own Arm-based processors for their data centers, Google Cloud today announced the Google Axion Processors that will be available in the future...
