Following AMD posting AMDGPU patches for HDMI 2.1 FRL support after the HDMI 2.1 open-source support was long blocked by the HDMI Forum, as part of working toward a complete HDMI 2.1 implementation in this AMD Linux driver it was followed by HDMI 2.1 Display Stream Compression (DSC) support. Now the latest on the AMDGPU HDMI 2.1 enabling path is enabling Auto Low-Latency Mode (ALLM) as well as HDMI Variable Rate Refresh!

With the Razer Blade 18 as the first laptop Razer's certifying for (Ubuntu) Linux use while testing it out I was predominantly using the NVIDIA R610 official driver stack. Some users were interested though in how well this laptop is working with the open-source, upstream Nouveau+NVK driver stack given Razer is marketing this high-end laptop for Linux use too. Before sending the review unit back I had run some graphics benchmarks to see how Nouveau+NVK was performing for this Razer Blade RZ09-0582 with the flagship GeForce RTX 5090 Laptop GPU.

It's been about a decade since seeing any new games released on the visually-impressive, Linux-friendly Unigine Engine. Unigine Corp has mostly been focusing on Unigine Engine usage for simulations and other professional applications, but coming as a surprise today is a new game being developed on their latest Unigine 2 engine technology.

13 Hours Ago - AMD - Ryzen Master For Linux?

In an interesting twist, patches this week posted to the Linux kernel mailing list are enabling AMD Zen 6 client desktop and laptop SoCs for the HSMP driver. Up to now the AMD HSMP Linux driver was just used for modern EPYC server processors while now we are seeing this HSMP driver supporting the upcoming Medusa and Olympic Ridge client platforms... Including mentions of overclocking and even noting "Ryzen Master" as the Windows-only software for overclocking and system management.

The Xen Project today released Xen 4.22 as the newest feature release of this open-source hypervisor popular for open-source virtualization in automotive systems and other embedded use-cases as well as the cloud.

17 Hours Ago - Mesa - Huawei Mesa Vulkan Driver

A Huawei engineer posted to the Mesa mailing list today over potentially upstreaming a Vulkan driver they have developed for an in-house GPU. However, at least in current form, this new in-house GPU Vulkan driver is likely dead in the water from being upstreamed into Mesa.

The Intel Arc A-Series graphics (DG2) remains in a bit of an awkward state on Linux due to the transition period moving from the i915 kernel driver to more modern and feature capable Xe kernel driver. It's only post-Alchemist where the Intel Xe driver is officially supported and used by default while those opting for the Xe driver with the A-Series can often enjoy better performance and functionality. Except one of the caveats in using the Xe driver on Alchemist GPUs has been the lack of proper media acceleration support.

Last week Debian developers began considering a general resolution over AI large language model (LLM) usage within the Debian project. They are now up to weighing five different proposals for how to permit or block AI/LLM usage in the Debian space.

Over the past few Intel VA-API Media Driver releases we have seen preparations made for Nova Lake video acceleration. That has continued today with the Intel Media Driver and Intel oneVPL GPU Runtime releases today with their new quarterly feature releases.

A new software creation that debuted this summer was YSERVER as a modern X11 server written in Rust largely by AI via Claude Code. This YSERVER implementation has continued implementing more X11 protocol and other functionality to get more desktop environments and apps working surprisingly okay on this vibe coded X11 server. YSERVER 1.4 is now available as the latest in this quest.

A few weeks ago there was excitement in the FreeBSD camp with FreeBSD 16 set to retire the last of its GPL code from the base system. While the retiring of the dialog code proclaimed that it was the last remaining piece of GPL software in the base system for FreeBSD, it turns out now that there is some GPL code within the FreeBSD kernel.

A set of patches posted today to the Linux kernel mailing list implement per-core Energy Performance Preference (EPP) boosting for recently-busy CPUs. This feature is designed to have a dramatic impact for Linux gaming and helping especially with the 1% low frame-rates improving by 31.8% on the Valve Steam Deck.

28 July 05:50 AM EDT - KDE - Ridiculous File Copy Times

Since 2014 there has been a KDE bug report titled Ridiculously slow file copy (multiple small files). With the Dolphin file manager or other KIO-based KDE programs, copying many small files can be much slower than using the cp command directly or other copying programs like rsync, Finally that issue is in the process of being resolved for addressing very slow copy times when dealing with many small files on the KDE Plasma desktop.

In addition to the deprecation and stripping down of AF_ALG, another piece of the Linux kernel crypto code steaming ahead toward removal is the crypto_rng abstraction layer.

ASUS laptops support a feature called "Whisper Mode" that intentionally slows down the fan speed and lowers the CPU clock speed in order to keep the device running cool and quiet. The open-source ASUS Armoury Linux kernel driver is now seeing patches to properly support this Whisper Mode on Linux.

27 July 05:28 PM EDT - AMD - AMD PMF Testing Tool

Looking to be added to the Linux kernel source tree for the upcoming Linux 7.3 cycle is test_amd_pmf, a small testing application for exercising the AMD Platform Management Framework (PMF) interfaces and dumping various system data points.

Last October on Phoronix we were first to point out there being some mysterious intrigue around a new x86 implementation from a "corporate entity other than Intel/AMD" with the developer involved not elaborating on the matter. Now that same developer has posted another semi-cryptic message to the Linux kernel mailing list to talk about 16-tile and 32-tile Advanced Matrix Extensions (AMX) implementations. To date Intel only has 8-tile AMX.

Fwupd 2.1.7 is out today as the newest update to this open-source firmware updating utility that pairs with the Linux Vendor Firmware Service (LVFS) for offering a nice firmware upgrade story on Linux systems.

Back in April, Framework Computer announced the Framework Laptop 13 Pro as a ground-up re-design of their modular/upgradeable laptop. This new Framework Laptop 13 Pro features a much larger battery (74Wh), LPCAMM2 memory support, a full CNC aluminum chassis, haptic touchpad, and a new power-optimized touch display.

Since 2017 in Linux 4.12 has been the Realtek rtl8723bs WiFi driver where it was introduced into the staging area and remains there nearly a decade later. The rtl8723bs driver for this Realtek 802.11n WiFi SDIO driver has seen a lot of code cleaning over the years and all these years later still is needing lots of code clean-ups from unnecessary code abstractions to dealing with malicious WiFi APs for what Greg Kroah-Hartman has called a "beast of a driver". The latest twist is there now being patches for adding Realtek RTL8723BS and RTL8723B onto the existing RTW88 driver.

Firewire still isn't dead yet on Linux. Current plans call for maintaining IEEE-1394 Firewire on Linux at least through 2029 and with today's Linux 7.2-rc5 kernel release is a fix for those wanting to leverage IPv4 networking over Firewire.

Following last month's beta release, Ubuntu Touch 24.04-2.0 is now available as the latest feature release for this Ubuntu 24.04 LTS derived mobile operating system for select smartphones and tablets.
