Some Qualcomm processors/SoCs on the mainline Linux kernel are left vulnerable to Spectre security issues since Qualcomm hasn't upstreamed patches for properly treating affected CPU cores to their relevant mitigations. But a new patch series from a Google engineer is working to get those Qualcomm CPU security mitigations in order...

As covered last month on Phoronix, Intel has been experimenting with Energy Aware Scheduling (EAS) for the Intel P-State driver with a goal of enhancing the power efficiency of Core Ultra "Lunar Lake" processors. Recently a second iteration of that work was posted for review ahead of possible inclusion in a future version of the Linux kernel...

After some six months of silence, this past week the NTSYNC LInux kernel driver patches were revived for completing this open-source driver to better match the Windows NT synchronization primitives to help with Wine / Proton (Steam Play) Windows gaming performance on Linux. Following those "v6" patches posted a few days ago, on Friday evening a seventh iteration of the patches were volleyed to offer up some API design improvements for this NTSYNC driver...

While not as popular as their Snapdragon SoCs, Qualcomm has been offering their Cloud AI line of accelerators for scalable AI inference. The current flagship is the Qualcomm Cloud AI 100 Ultra as a 150 Watt rated PCIe Gen4 x16 card for up to 870 TOPS INT8 performance, 576MB of SRAM, and 128GB LPR4x memory. But given the latest open-source Linux driver patch activity, Cloud AI 200 "AIC200" wares are on the way...

Ahead of the Arc B580 graphics card hitting Internet retailers tomorrow, today the review embargo lifts on the Intel Arc B580. Here is what to expect from the Linux driver support at launch for the Intel Battlemage graphics cards and how the Arc B580 is performing for Linux gaming/graphics workloads.

Now that the initial Intel Arc B580 graphics card gaming review on Linux is out, for productivity-minded users you may be more curious about the GPU compute potential... Here are some initial OpenCL and Level Zero results for the Intel Arc B580 graphics card compared to the Intel Arc A-Series and the AMD Radeon and NVIDIA GeForce competition under Linux.

Earlier this month as part of patches for cleaning up x86 32-bit kernel code for x86_64 systems, there was a patch to drop support for 32-bit x86 KVM host support. That patch has now been split off into its own patch series with also now raising the prospects of ending 32-bit KVM host support across all CPU architectures rather than being just an x86-only change...

While the Linux 6.13 merge window only recently ended and that kernel won't be out until around the end of January followed by the start of the Linux 6.14 merge window, Intel software engineers on Wednesday sent out their first two pull requests to DRM-Next of new kernel graphics driver features they are readying for this next version of the Linux kernel...

With the in-development Linux 6.13 kernel one of the biggest features for those using new AMD EPYC 9005 "Turin" processors is using the AMD P-State driver by default for servers/motherboards with ACPI CPPC support enabled. But even for platforms without that where ACPI CPUFreq remains the default, the Linux 6.13 kernel is still showing some nice incremental uplift at large on these new AMD server processors. Here are some Linux 6.11 vs. 6.12 vs. 6.13 Git kernel benchmarks using an AMD EPYC 9575F 64-core server.

Going back to April 2024, SiFive announced the HiFive Premier P550 as an interesting RISC-V developer board to succeed their HiFive Unleashed that was a nice little RISC-V board. There were delays in shipping the HiFive Premier P550 but they have been making progress and are now ready to ship Ubuntu 24.04 LTS pre-installed on this RISC-V board. They have also lowered the pricing on these RISC-V boards...

Last week I wrote about Linux patches cleaning up x86 32-bit kernel builds for x86_64 CPUs. The new iteration of those patches were sent out today, including the addition of a patch adding the CONFIG_X86_64_NATIVE Kconfig tunable for enabling "-march=native" kernel builds to cater your optimized kernel compilation for the CPU on which you are building the kernel...

Currently the Linux kernel's "perf" performance monitoring subsystem has a limit on 2,048 CPU cores for its CPU map that is set by the MAX_NR_CPUS value. But that's becoming not enough in today's high core count era that patches are looking to raise it to a 4,096 CPU core limit by default...

For those wanting to run Coreboot or Coreboot-derived firmware on a modern desktop motherboard with good performance and features, the main contender currently is 3mdeb's Dasharo downstream that can be flashed on the MSI PRO Z790-P/Z790-P motherboards for using with Intel Core Alder Lake and Raptor Lake processors. Firmware consulting firm 3mdeb today published a new Dasharo firmware update for the MSI PRO Z790-P WIFI motherboard...

Back in May for the Linux 6.10 kernel the initial bits of the NTSYNC driver was upstreamed for helping to emulate the Windows NT synchronization primitives so Windows games running under Wine/Proton (such as Valve's Steam Play) can enjoy a very nice performance boost. That NTSYNC code for Linux 6.10 wasn't yet in functioning shape and now a half-year later the newest NTSYNC patch series has been sent out for review...
