Earlier this year SiFive announced the HiFive Premier P550 RISC-V development board with plans for shipping in July. That timeframe for shipping since passed but SiFive today issued a new update on their RISC-V development board...

On Sunday there was a new patch posted by an Intel Linux engineer to boost the Lunar Lake Linux performance out-of-the-box for ASUS laptops by adjusting the new ASUS Intelligent Performance Technology "AIPT" feature so that Linux follows the same behavior as Windows 11. My initial testing of this ASUS AIPT patch has indeed shown the Core Ultra 7 256V "Lunar Lake" yielding much better performance with this patch applied.

Making for an exciting Monday morning, AMD Linux engineers have kicked off the new week with a patch series introducing an exciting and long-awaited change: using the AMD P-State CPU frequency scaling driver by default for EPYC server platforms moving forward rather than the ACPI CPUFreq driver...

Over the past week Linux creator Linus Torvalds has been active on a Linux kernel mailing list thread around avoiding barrier_nospec() in copy_from_user() due to being "overkill and painfully slow." The conversation evolved into low-level discussions over CPU behavior and how to best handle, differing behavior/requirements with new Intel CPUs supporting Linear Address Masking (LAM), and the overall headaches these days around CPU security mitigations...

Building off Friday's release of Wine 9.20 for running Windows games/applications on Linux, Hangover 9.20 is now available for this extension of Wine that builds off that codebase while pairing it with an x86/x86_64 emulator for running Windows programs on other CPU architectures like ARM64 Linux. With Hangover 9.20 they have restored the ability for running Win64 applications on ARM64 Linux hosts...

Since purchasing an Intel Core Ultra Series 2 "Lunar Lake" laptop for Linux testing last month, the performance has been coming in below expectations. Among the tests were finding Xe2 graphics on Lunar Lake performing slower that under Windows 11 and in comparison slower than Meteor Lake graphics on Linux. Intel engineers have been able to reproduce my original findings and they uncovered the culprit is a new ASUS laptop feature called AIPT. In turn a patch was posted today for supporting ASUS AIPT controls under Linux to fix this low Lunar Lake Linux performance...

Several Phoronix readers have written in this Sunday over concerns of Bitwarden further moving away from open-source. Bitwarden is a password management service that leverages an encrypted vault and supports multiple clients/platforms. Bitwarden operates on a freemium model and has provided some code as open-source while there are new concerns over Bitwarden further pivoting away from open-source...

With ReiserFS having been deprecated for two years with plans to remove it in 2025, the upcoming Linux 6.13 cycle for what will be the first major kernel release of the new year and past the Linux 6.12 LTS kernel is expected to do just that...

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...

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...
