Redis 8.0 Released: Now Tri-Licensed With AGPLv3

Last year Redis made the much criticized move to Redis Source Available License v2 and Server Side Public License v1 (SSPL) licensing. The move was widely panned by the open-source community and led to the Linux Foundation forking it as Valkey and also other forks like Redict coming about. In the months since many Linux distributions have switched from Redis to Valkey. Now Redis Labs announced today that with the Redis 8.0 release, they are adding AGPLv3 to the licensing mix...

GCC 15 Compiler Demonstrating Measurable Performance Gains For AMD EPYC Turin

With the recently released GCC 15 (GCC 15.1) compiler besides adding new language features, enhancements to help developers in debugging build failures, and other refinements, there is the never-ending quest of compiler performance optimizations. Since the recent GCC 15.1 release candidate I've been testing this annual compiler feature release on more hardware, including several AMD 5th Gen EPYC "Turin" servers to great success compared to the prior GCC 14 stable series.

Patch Posted For Addressing The AMD CPU Performance Regression On Linux 6.15

As a follow-up to the Phoronix article a few days ago entitled A Linux 6.15 Performance Regression Hits Modern AMD CPUs, there continues to be activity to address this issue with the performance impact catching the upstream kernel developers off guard. I've tested a patch now that does address the issue while still carrying the KVM protections desired...

Framework 13 With Strix Point, Cheap RISC-V & Linux Kernel Happenings Topped April

During the past month on Phoronix were 249 original news articles and another 23 featured Linux hardware reviews and multi-page benchmark articles. There was a lot of interesting topics in April from the launch of the Framework Laptop 13 powered by AMD Strix Point, an interesting and cheap RISC-V board coming about, the Lenovo ThinkPad X1 Carbon Gen 13 proving to be an interesting low-power Linux laptop, Ubuntu 25.04 and Fedora 42 releasing, and much more...

OSU Open Source Lab At Risk Of Closure This Year Due To Lack Of Funding

For those that have spent any length of time in the open-source world have likely come across osuosl.org when downloading open-source projects that often are mirrored at the Oregon State University Open Source Lab (OSU OSL). The OSU OSL over the past two decades has also provided VMs for various architectures from x86 and AArch64 to POWER for CI and testing purposes to open-source projects, among many other support roles. Unfortunately, the OSU OSL risks closure this year...

Intel Makes "AI Flame Graphs" Open-Source

Intel's AI Flame Graphs software is now open-source. This is a project that started for Intel's Tiber AI Cloud to provide more insight into AI accelerator/GPU usage and hardware profiling of the full software stack. After being an internal/customer-only software project for some months, AI Flame Graphs is now open-source...

NVIDIA Posts 60 Patches For Open-Source Hopper & Blackwell GPU Support On Nouveau

Ben Skeggs formerly of Red Hat who had been the maintainer of the Nouveau Linux kernel driver for reverse-engineered open-source NVIDIA driver support had joined NVIDIA last year and continued his engagements with the open-source Linux community. For ending out April there's a big surprise... The NVIDIA engineer posted a set of 60 patches enabling support for NVIDIA Hopper and Blackwell GPUs atop the open-source Nouveau kernel driver...

Firefox 139 Beta Delivers Faster HTTP/3 Upload Performance

Firefox 138 was released yesterday and wasn't particularly exciting besides enhanced profile management and Tab Groups support... Aside from that it was a pretty basic release. In turn Firefox 139 is now in beta and that release does bring some items worth mentioning like faster HTTP/3 upload performance...

Ubuntu 25.04 & Fedora 42 Hit A Long Sought Milestone With HDR Support Working Well On The Linux Desktop

It's almost majestic: HDR display support working on the Linux desktop. If you asked me at the start of the calendar year if I'd expect to see modern Linux distributions shipping with working HDR display support in H1'2025, I would have been doubtful. But after a lot of miraculous work that landed across numerous upstream repositories over the past two months or so, everything has come together just in time for the likes of Ubuntu 25.04 and Fedora Workstation 42. There still are apps not supporting HDR and the like, but the core infrastructure is in place and working. The past two weeks I've begun testing out the Linux HDR desktop experience with the ASUS ROG Swift OLED PG27UCDM 27-inch 4K display. Between the ASUS PG27UCDM's QD-OLED display and HDR support enabled under Linux, it delivers a very beautiful Linux desktop experience.

A Linux 6.15 Performance Regression Hits Modern AMD CPUs

Separate from last week in uncovering a big performance regression on Linux 6.15 affecting workloads like Nginx and that regression getting fixed, I unfortunately discovered another heavy-hitting regression on Linux 6.15. This latest performance regression has been bisected and a possible fix is being thought through by the relevant party, but for the moment has yet to be fixed upstream and affects modern AMD processors.

Ubuntu 25.04 Advancing The Performance Of The System76 Thelio Astra With Ampere Altra

With the release of Ubuntu 25.04 this month I've looked at its performance on x86_64 laptops and desktop hardware to nice gains on server. That testing so far was focused on Intel and AMD systems given my abundance of x86_64 platforms. Last week I began testing Ubuntu 25.04 ARM64 on the System76 Thelio Astra powered by Ampere Altra processors. For those considering the Ubuntu 25.04 upgrade and not minding that it's not a Long Term Support (LTS) release, Ubuntu 25.04 is also allowing for greater performance on ARM hardware.

Fair DRM Scheduler v4 Running Well On Steam Deck, "Looks Solid"

Tvrtko Ursulin of Igalia has been pursuing the Fair DRM Scheduler as a "fair" scheduling policy to help with multiple applications/processes aiming to make use of the GPU concurrently. With this week's v4 patch-set to the DRM Fair Scheduler there are some big code changes but overall looking well as a nice scheduling policy for multiple apps/games/processes wanting equal access to GPU resources...

Intel 200S Boost Performance Mode Benchmarks On Linux

This week Intel announced "200S Boost" for Core Ultra "Arrow Lake" K-Series desktop processors as effectively a new overclocking profile rolling out to existing Z890 motherboards via a BIOS update. Enabling the 200S Boost profile is said to help with low-latency workloads like gaming by allowing higher fabric / die-to-die / memory frequencies. While some Windows benchmarks have begun emerging for the Intel 200S Boost mode and some limited gains, I was curious about the performance under Linux so here are some 200S Boost benchmarks with the Core Ultra 9 285K on Ubuntu 25.04.

Bcachefs Landing Fixes So Its Case Insensitive Support Actually Works

Nearly two years ago patches for casefolding / case insensitive file and folder support on Bcachefs were posted by a Valve/Linux developer. That support was upstreamed into the Bcachefs kernel driver but it turns out that it never properly worked. Patches now set for merging into the Linux 6.15 will fix that case insensitive file/folder opt-in support so that it is now properly supported...

Intel Linux Graphics Driver Patches Updated For DRM Panic Support

One of the interesting new features merged to the Linux kernel last year was the DRM Panic infrastructure so that Linux can display an error screen akin to Windows' "Blue Screen of Death" when encountering problems. With follow-on kernel releases it's been extended to add QR code error messages and other improvements. But DRM Panic does require the support/cooperation of the different Direct Rendering Manager drivers and so far Intel graphics haven't been supported...

Lenovo ThinkPad X1 Carbon Gen 13 Aura Can Work Well As A Solid Linux Laptop

The Framework Laptop 13 with AMD Strix Point is now shipping that as detailed in our review earlier this month can provide for a very capable Linux laptop for Linux developers, creators, and enthusiasts. But for those hesitant about the high price and still weeks away before they have shipped all their pre-orders, if you are principally concerned about battery life, and/or after proven build quality backed by on-site warranty and other warranty/support options, the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition ends up being a solid option for a very reliable and well-engineered laptop for Linux use. Here is a look at the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition on Linux that is powered by Intel Lunar Lake.
