Linux Patch Sparks Differing Views Over External Monitor Handling With iGPU vs. dGPU
Linux Patch Sparks Differing Views Over External Monitor Handling With iGPU vs. dGPU
39 Minutes Ago - Hardware - Laptop + External Monitor - 4 Comments

Canonical kernel engineer Kai-Heng Feng posted a patch on Tuesday for capable laptops to switch their external monitor connections to be routed through a laptop's discrete GPU rather than the integrated GPU. With select laptops this can be done with an ACPI call but raises questions among upstream developers rather this change is indeed desirable.

VFX & Animation Studios Urged To Upgrade To RHEL 9 Or Rocky Linux / AlmaLinux 9
VFX & Animation Studios Urged To Upgrade To RHEL 9 Or Rocky Linux / AlmaLinux 9
16 August 06:35 PM EDT - Operating Systems - VFX Linux Recommendations - 7 Comments

VFX Reference Platform as a standards body that aims to help standardize software platforms in the realm of digital content creation (DCC) has published a detailed report for studios to consider in choosing their next Linux platform. Their new recommendations for visual effects and animation studios about moving to newer Linux distributions over the next year -- especially with many still relying on CentOS 7 -- is for moving to Red Hat Enterprise Linux 9 otherwise one of the downstreams like Rocky Linux or AlmaLinux. Close behind in their recommendations and as a longer-term objective is also tossing some support behind Ubuntu Linux.

For those weighing whether to pursue the full eight memory channel configuration for the new Ryzen Threadripper 5000 series or starting out with just four or six memory modules, here are some reference benchmarks across four, six, and eight memory channels with the AMD Ryzen Threadripper PRO 5965WX 24-core processor while running Ubuntu Linux.

AMD CPU Microcode Loading On Linux Being Fixed Up To Be Per-Thread
AMD CPU Microcode Loading On Linux Being Fixed Up To Be Per-Thread
16 August 07:00 AM EDT - AMD - Not Per-Core - 14 Comments

Up to this point loading updated CPU microcode on AMD processors under Linux has checked just to ensure every physical CPU core was loaded with the new microcode but not sibling threads for SMT processors. While logically that makes sense, it turns out some AMD microcode updates do carry out per-thread modifications that means the microcode updating needs to be carried out on every thread. A Linux fix is on its way to the kernel to adjust that behavior.

OpenSUSE Developers Continue Discussing x86_64 Microarchitecture Feature Levels

Ahead of the upcoming openSUSE/SUSE Adaptable Linux Platform (ALP), whether to raise the x86_64 micro-architecture feature level required by the Linux OS continues to be evaluated and what options there are for making use of newer x86_64 instruction set extensions without necessarily forcing tightened CPU requirements / eliminating old hardware support.

When it comes to Linux on Arm laptops the recent excitement has been around the Asahi Linux porting work for the Apple M2 MacBooks and Linux 6.0 supporting the Qualcomm Snapdragon 8cx Gen3 and the flagship Lenovo ThinkPad X13s Arm laptop. Launched a few years ago though was the Lenovo Yoga C630 powered by a Qualcomm Snapdragon 850 and thanks now to the work of Linaro that older Arm laptop is seeing Linux support improvements.

Qualcomm Posts "QAIC" DRM Accelerator Driver For Linux
Qualcomm Posts "QAIC" DRM Accelerator Driver For Linux
15 August 03:00 PM EDT - Linux Kernel - Qualcomm Cloud AI Accelerator - Add A Comment

After Qualcomm announced their Cloud AI 100 Accelerator back in 2019, in 2020 during the early days of the pandemic they posted a Linux driver for this accelerator. That driver didn't get picked up for the mainline Linux kernel and two years later there still is little fanfare around the Qualcomm AI Cloud Accelerator hardware. However, now they have posted a new Linux driver that goes the DRM driver route.

Greg KH Recommends Avoiding Alder Lake Laptops - Intel Webcam Linux Driver Long Ways Out
Greg KH Recommends Avoiding Alder Lake Laptops - Intel Webcam Linux Driver Long Ways Out
15 August 06:50 AM EDT - Intel - New Webcamera Needs Lots Of Work - 45 Comments

Greg Kroah-Hartman as the Linux kernel's stable maintainer and effectively Linus Torvalds' second-in-command has suggested avoiding Intel Alder Lake laptops. While much of the Alder Lake laptop support for Linux is in good shape, the exception is around web cameras. These newer laptops with Intel's latest web-camera tech are not currently supported by the mainline kernel and require proprietary software for use. Some platforms like Ubuntu and ChromeOS are picking up these blobs for now while a proper open-source, upstream solution is likely months -- or likely about one year -- away.

MGLRU v14 Released For Improving Linux Low-Memory Performance
15 August 05:28 AM EDT - Linux Kernel - MGLRU v14 - 9 Comments

While Linux 6.0 will bring a lot of shiny new features, Multi-Gen LRU (MGLRU) is one of the anticipated changes that isn't going to land now until Linux 6.1. But in the interim, MGLRU v14 was posted today that re-bases the code against 6.0-rc1 to help facilitate more testing of this kernel change that primarily helps Linux systems under memory pressure.

Not only is the AMD EPYC performance looking real good for Linux 6.0, but many of the scheduler changes and common kernel improvements also carry over well for Intel's Xeon Platinum 8380 "Ice Lake" server processors too. For your viewing pleasure this weekend are some initial benchmarks looking at Linux 5.19 stable compared to Linux 6.0 Git as we approach the end of the merge window.

Glibc 2.36 Dropping DT_HASH Has Been Breaking Easy Anti Cheat Games With Steam Play
13 August 08:00 PM EDT - Linux Gaming - EAC Games Borked With Glibc 2.36 - 57 Comments

Those on rolling-release Linux distributions that are quick to adapt to new toolchain updates are finding Easy Anti Cheat (EAC) enabled games breaking when running on the recently released Glibc 2.36. The breakage stems from the DT_HASH section being dropped in GNU C Library but EAC being among the few software still expecting that section rather than DT_GNU_HASH.

AMD Radeon 680M Graphics Benchmarks Across Various Linux Kernel, Mesa Versions
13 August 01:20 PM EDT - Radeon - Radeon 680M - 1 Comment

With the Ryzen 6000 "Rembrandt" mobile processors most exciting about these Zen 3+ SoCs has been the energy efficiency improvements and moving from Vega to RDNA2 graphics as with the Radeon 680M found on the Ryzen 7 PRO 6850U that I have been running many Linux benchmarks on over the past several weeks. For those wondering if it pays off moving to a newer Linux kernel or Mesa version with Radeon 680M integrated graphics, here are some reference benchmarks I recently conducted.

Intel Preps HWMON Support For Linux Driver To Expose Power / Voltage / Energy Reporting
12 August 02:21 PM EDT - Intel - Linux i915 HWMON - 2 Comments

While much of the Intel Arc Graphics "Alchemist" (DG2) support appears squared away for Linux 6.0 besides the support still being hidden behind the flag requiring i915.force_probe= to actually enable the experimental support, there still are various DG2 discrete GPU features being tackled by the open-source Intel kernel graphics drivers. One of those "extras" still working its way to the kernel is HWMON subsystem integration to be able to expose power / voltage / energy reporting.

While Intel's performance-optimized Clear Linux rolling-release distribution is known for its aggressive performance optimizations, their kernel build had been going with the default "-O2" optimization but last week did switch over to rolling their kernel with -O3.

LoongArch Enables PCI & Other Features For Linux 6.0
12 August 05:26 AM EDT - Linux Kernel - LoongArch With Linux 6.0 - Add A Comment

While support for the loongArch Chinese CPU architecture was merged in Linux 5.19, it wasn't actually enough to yield a booting system due to some driver code not yet being finished and ready for merging in time. LoongArch was allowed to merge that preliminary code in v5.19 so the Glibc support could land and now for Linux 6.0 more of the CPU port is ready to hit the kernel.
