Maximizing The Performance & Power Efficiency Of AMD Ryzen AI Max+ 395 With Platform Profiles

Last week I began posting Linux benchmarks of the flagship "Strix Halo" SoC, the AMD Ryzen AI Max+ PRO 395 with powerful Radeon 8060S graphics using the HP ZBook Ultra G1a laptop. Both the CPU and GPU results for the data published thus far have been mighty impressive and done at the Ubuntu Linux defaults... But the Ryzen AI Max+ 395 within the ZBook Ultra G1a can be pushed even further by leveraging the ACPI Platform Profiles capabilities. In this article is showing how much further performance -- and the power costs -- can be achieved out of this AMD Strix Halo SoC when leveraging the HP Power Profiles as well as the power efficiency for those wanting to run the SoC instead in the "power saver" / "low power" configuration.

AMD Releases ROCm 6.4.1 With RDNA4 GPU Support

Well, this is a pleasant surprise... Less than 24 hours after the AMD Computex 2025 keynote where better/more-timely ROCm support for client GPUs was brought up, AMD ROCm 6.4.1 is now officially released. With ROCm 6.4.1 there is formal support for RDNA4 GPUs, including the Radeon RX 9000 series consumer graphics cards...

libinput Preparing To Introduce A Lua-Based Plugin System For Modifying Devices/Events

The libinput input handling library that's used by both X11 and Wayland based environments on the Linux desktop is preparing to introduce a Lua-based plug-in system. Via Lua scripts it will be possible to modify evdev input events / input device behavior to deal with quirky/broken input devices and better workaround other problems that aren't currently easily addressable...

Linux Improvements Boost AMD Ryzen Threadripper 7000 Series Performance Since Launch

With the AMD Ryzen Threadripper 9000 series having just been announced at Computex, it's a good time to revisit the Ryzen Threadripper 7000 series performance ahead of those Zen 5 HEDT CPUs launching in July. In this article is a look at how the AMD Ryzen Threadripper 7970X 32-core and 7980X 64-core HEDT processors have evolved on the same system with the software updates released since their late 2023 debut. Overall the AMD Ryzen Threadripper 7970X and 7980X Linux performance is up by about 8% overall since launch day less than two years ago with the 64-core processor.

NVIDIA Outlines Current Wayland Limitations & Future Driver Plans

Last year NVIDIA began publicly outlining known Wayland limitations for their driver and future support plans. This week NVIDIA put out updated information concerning known gaps in Wayland support as well as their ongoing future driver plans for enhancing the feature compatibility under this X11 successor...

Linux Scheduler Patches Aim To Address Performance Regression Since Last Year

A set of Linux kernel scheduler patches posted today are trying to address some performance regressions observed since the Linux 6.11 kernel that was released back in September 2024. These performance-fixing patches are flying under a "request for comments" flag and some of the regressions are tricky and perhaps not completely resolved, but it looks to be a step in the right direction...

Adaptive Sharpness Property Still Being Worked On For Intel Lunar Lake & Newer On Linux

Since last summer Intel open-source driver engineers have been working to make use of Lunar Lake's new adaptive sharpening capabilities under Linux. This is being done via a proposed DRM sharpness property for communicating sharpness preferences while the hardware capabilities within Lunar Lake equate to minimal power and performance costs when in use. The DRM sharpness property support still has yet to be mainlined but the newest iteration of the patches were posted on Monday...

Intel Adds OpenMP Multi-Threading To Its Speedy x86-simd-sort Library

Intel's x86-simd-sort open-source project is a C++ template library for high performance sorting routines that can leverage AVX2 and AVX-512 for crazy fast sorting. The x86-simd-sort code in turn is used by Numpy, more recently adopted by PyTorch too, and has shown off the great performance potential of AVX-512 for very fast sorting algorithms. Out today is x86-simd-sort 7.0 and it's even faster due to now supporting OpenMP parallelization...

Samsung Back To Working On Upstreaming Tesla FSD SoC Support In The Linux Kernel

In early 2022 Samsung engineers began working on upstreaming support for the Tesla Full Self-Driving "FSD" SoC to the mainline Linux kernel. Those early patches were mainlined in Linux 5.18 and later in 2022 turned to working on the PCIe support for the Tesla FSD SoC with the mainline kernel, but then work seemingly ceased on this upstreaming effort. More than two years later, the work was restarted today with Samsung posting the latest patches for enabling PCI Express support for the Tesla FSD SoC in the Linux kernel...
