Merged today to Linux 6.12 Git were bug fixes to AMD's Indirect Branch Predictor Barrier (IBPB) handling that can be optionally used as part of the Retbleed and Speculative Return Stack Overflow (SRSO) mitigations on older AMD processors...

In a rather surprising post this morning, laptop vendor MALIBAL that offers both Linux and Windows systems is suggesting to not support the Coreboot project for open-source system firmware...

The OpenCL 3.0 compute specification has been out in finalized form since September 2020. Since then NVIDIA's official Windows/Linux drivers have been exposing OpenCL 3.0 going back to 2021, the Intel Compute Runtime stack has also been exposing OpenCL 3.0 support for years, and even with Mesa's Rusticl open-source OpenCL implementation it's beginning to see Gallium3D drivers with conformant OpenCL 3.0. Yet if installing the AMD ROCm compute stack right now, you'll see OpenCL 2.1. But it looks like OpenCL 3.0 will soon be here for ROCm...

Ubuntu Linux maker Canonical has announced the availability of an Intel NPU driver Snap package within their Snap Store to make it easier to leverage the Intel neural processing unit (NPU) on Core Ultra processors within Ubuntu Linux...

Merged to upstream SDL today is an OpenVR video driver that was developed at Valve Software...

Germany's Sovereign Tech Fund (STF) is today celebrating its second anniversary for "empowering public digital infrastructure." In the past two years it has invested more than €23 million (about $24.94M USD) into sixty open technologies...

Microsoft announced today the new and now open-source OpenHCL paravisor for the virtualization stack for enabling Intel TDX and AMD SEV-SNP confidential computing virtual machines (VMs) with this Rust-written software stack. This effort by Microsoft has been five years in the making and is now open-source and will continue to be developed in the open...

Following the recent patch work for enabling the Intel 5th Gen NPU premiering with Panther Lake, a new patch series posted today brings a number of improvements for this Intel neural processing unit driver -- including the ability to handle larger workloads...

Continuing on with the testing around the AMD EPYC 9005 series "Turin" processors, today is a look at the Simultaneous Multi-Threading (SMT) performance impact for Turin while using the AMD EPYC 9755 as the highest-end "Turin Classic" processor with 128 cores / 256 threads. Similar SMT on/off tests for "Turin Dense" with the EPYC 9965 192-core / 384-thread will also be coming in a future benchmarking comparison on Phoronix. These tests are mainly intended for reference purposes for those curious about the SMT benefits at such high core counts and what workloads may or may not still benefit from SMT especially when having so many threads while using 12-channel DDR5-6000 memory.

PyTorch 2.5 is out today as the latest major update to this widely-used machine learning library...

Following a proposal that began last month, Red Hat engineer Nikita Popov was nominated to become the new lead maintainer for LLVM. Following unaminous approval, as of last week in LLVM Git he's been appointed the official lead maintainer for this critical open-source compiler stack...

Earlier this month I wrote about Intel's Linux software engineers posting patches adding 5th Gen NPU support to the IVPU accelerator driver for that updated neural processing unit to be found with next-gen Panther Lake processors. Those 5th Gen NPU driver patches for Panther Lake are now queued for introduction with the upcoming Linux 6.13 kernel cycle...

Karol Herbst of Red Hat presented in Montreal last week at the X.Org Developers' Conference (XDC 2024) on the current state of Rusticl as the Rust-written OpenCL implementation for Gallium3D drivers within Mesa...

Last week at XDC 2024 in Montreal was a status update on AMD's GPU compute virtualization support around their open-source Linux GPU driver and ROCm compute stack...

OGRE-Next 3.0 has debuted this week as the newest version of the Object-Oriented Graphics Rendering Engine Next Generation for serving as an open-source 3D graphics rendering engine...

Following last week's release of the LLVM/Clang-downstream AOCC 5.0 for optimized compiler support extended to Zen 5 CPUs, the GPU side of the house at AMD this week released AOMP 20.0-0 as their LLVM/Clang downstream focused on GPU device offloading...

Qualcomm engineers have developed VCL as a new open-source OpenCL driver for use with VirtIO-GPU for providing OpenCL hardware acceleration within virtual machines...

Last week at the X.Org Developer's Conference (XDC2024) in Montreal there was a talk showcasing Mesa's open-source Radeon "RADV" Vulkan driver running atop Windows 11...

For those that have been eager to see more Intel Core Ultra Series 200V Lunar Lake Linux testing, here is the latest installment of testing as well as an update from Intel following my Lunar Lake Linux testing recent reports. Today's article is looking at Intel Lunar Lake versus AMD Strix Point across different ACPI Platform Profile configurations for whether you are after peak performance or the most power savings.

The GNU Compiler Collection (GCC) support for the C23 programming language standard is now considered "essentially feature-complete" with GCC 15. As such they are preparing to enable the C23 language version (using the GNU23 dialect) by default for the C language version of GCC when not otherwise specified...
