Yesterday I looked at how the Intel OpenCL GPU compute performance evolved for the Arc Graphics B580 in the one month since that first Battlemage graphics card premiered. There were nice Intel GPU compute optimizations merged over the past month to improve the experience. Here are some Linux graphics/gaming benchmarks for the Intel Arc B580 comparing the prior launch day Linux driver performance to where the Mesa performance is at now...

The modern GNOME desktop hasn't had a core application to playback audio files although many different audio/multimedia players exist. But now for the upcoming GNOME 48 desktop release, there is now a promoted core app for audio playback: Decibels...

ARM64 ILP32 is the Armv8 architecture with a 32-bit ABI rather than 64-bit -- akin to the "x32" x86 effort that never really took off on Linux. ARM64 ILP32 support never ended up making it into the mainline Linux kernel or GNU C Library but did appear within the GNU Compiler Collection. But years later and little use, GCC developers are consider deprecating ILP32 support ahead of its eventual removal...

Back in 2022 there were Linux kernel developers like Linux's second-in-command Greg Kroah-Hartman recommending that Intel Alder Lake laptops be avoided. This was due to the Intel web camera support in those new-at-the-time laptops yet to be properly upstreamed and relying on binary bits. Over time that Intel IPU6 MIPI camera support has seen portions of the code upstreamed into the mainline Linux kernel and distributions like Fedora taking extra steps to make them work but still in 2025 those with newer Intel laptops boasting the latest web camera technology are often facing a challenging experience...

It's not only the Intel GPU compute stack seeing some nice improvements recently but over with the Mesa 25.0-devel code for the Intel "ANV" open-source Vulkan driver there have been some new performance optimizations arriving this week...

Last month with the launch of Intel Battlemage with the Arc B580 graphics card, there was fairly nice open-source GPU compute performance but with some outliers... Today it's a pleasure to report that with the newest open-source GPU compute stack as of this past week, there are some nice Xe2 / Battlemage improvements for enhancing the performance of some OpenCL workloads and also correcting the performance of some workloads that were in poor standing on launch day.

Fedora Linux has already supported making use of glibc HWCAPs for allowing libraries to be built for different x86_64 micro-architecture feature levels for performance-sensitive code where it can pay off when leveraging AVX/AVX2 or other newer Intel/AMD CPU instruction set extensions. For Fedora 42 is now a proposal to extend that further to allow binary executables to also leverage glibc HWCAPs for better performance...

Google engineers and others have been talking about Address Space Isolation "ASI" for the Linux kernel to better deal with speculative execution attacks and other CPU vulnerabilities. Last summer there were some new "request for comments" patches working on Linux Address Space Isolation and today a second iteration of those RFC patches were published. They are now out for review but they are unlikely to see much use: the I/O throughput as measured by FIO takes a 70% hit...

The Intel Haswell CPUs were originally introduced back in 2013 and great for the time. Under Microsoft Windows the driver support has long been obsolete but under Linux with Intel's open-source driver support there is still even the occasional fix all these years later. Coming up for the Linux 6.14 kernel cycle in 2025 is a fix to benefit Haswell and similarly aged Intel platforms with integrated graphics...
