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.
