Earlier this month I looked at the AMD RDNA 3.5 graphics with Strix Point between Windows 11 and Ubuntu 25.04 Linux. The testing showed the AMD RDNA 3.5 graphics on the open-source Linux driver up to around 96% the performance of Radeon Software on Windows. The most frequent question that came up from that most recent round of benchmarking was wondering how the Intel Xe2 graphics on Core Ultra Series 2 "Lunar Lake" now compares between Windows 11 and Linux given that both drivers have been maturing the past several months. Here's the story of the Xe2 graphics between Windows 11 and Ubuntu 25.04 while using a Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition laptop.
Being worked on for a while now by engineers from Amazon, Microsoft, and Google has been Kexec HandOver "KHO" as a means of allowing some kernel state to be retained when Kexec'ing into a new kernel such as for maintenance/security updates. The KHO patches in recent days were queued up into Andrew Morton's "MM" staging area leading to hope that this work is ready for mainlining with the Linux 6.16 kernel cycle this summer...
A decade after Intel acquired FPGA maker Altera for $16.7 billion and recently working to make Altera an independent company, Intel announced today it has sold 51% of its Altera business in a deal that values that business at $8.75 billion...
The first Linux patch was posted today by an Intel engineer that explicitly mentions "Bartlett Lake" in opening the door for any other Linux kernel patches explicitly catering to Bartlett Lake processors...
After various commits to Mesa 25.1 in recent days in preparing for a new paired context registers feature of AMD RDNA4 (GFX12 graphics), the feature today is wired up for the Radeon Vulkan driver "RADV" with the upcoming Mesa 25.1 release. This feature has the possibility of helping performance for new AMD RDNA4 hardware but the performance benefits at this time aren't clear...
Sent out as a request for comments today is a patch series implementing PCACHE, a persistent memory cache for block devices. PCACHE was born out of code originally designed for the CXL block device driver but ultimately is useful outside the context of Compute Express Link as well...
While LLVM LLD and Mold are two popular linkers on Linux systems with the latter being known for its impressive speed and much faster than GNU LD and Gold, this past week Qualcomm open-sourced a new linker: ELD...
