Patches back in 2013 were proposed for "PRAM" as persistent over-kexec memory storage to allow saving of memory pages across kernel reboots via kexec or when hitting a new kernel via kexec. Nearly one year ago Oracle retook up the effort and sent out PKRAM as their "preserved-over-Kexec" RAM and now finally a second iteration of PKRAM has been published...

With AMD's busy Q1 of introducing the Radeon RX 6700 XT graphics card, introducing the Ryzen 5000 mobile series, the AMD EPYC 7003 "Milan" series launch, and continuing to advance their open-source/Linux software efforts, it was another busy quarter. Here is a look back from the Linux/open-source perspective of what interested readers the most...

Today's the day that we can finally talk about the performance of Intel's "Rocket Lake" processors under Linux. The past several weeks we have been extensively testing the Core i5 11600K and Core i9 11900K processors under Linux. Here is a look at the very exciting Gen12 Xe Graphics performance out of these new desktop CPUs, the Linux gaming performance, and then over 300 other benchmarks looking at the CPU/system performance of the i5-11600K / i9-11900K processors against the prior generation Comet Lake parts and the AMD Ryzen 5000 series competition.

While looking forward to the NVIDIA 470 series Linux driver for Wayland support improvements, before getting there NVIDIA is first introducing the 465 driver series. Today marks the first publicly available NVIDIA 465 Linux driver beta...

For longer than the past year Intel engineers have been working on wiring up the Linux kernel support to handle split lock detection and bus lock detection. Back in Linux 5.7 the split lock detection landed for warning or even killing the offending software should a split lock occur due to the significant performance impact and possible denial of service. Now it's looking like the bus lock detection code could be ready for mainline...

With Intel set to announce 3rd Gen Xeon Scalable "Ice Lake" CPUs next week, it's a good time for looking back to see how the Linux performance has evolved since the introduction of 2nd Gen Xeon Scalable "Cascade Lake" processors back in 2019. In this article is a look at the Xeon Platinum 8280 performance back at launch under both Ubuntu and Clear Linux compared to the current state of both distributions on the same hardware. There are also additional tests with those latest Linux images seeing how Ubuntu 21.04 is shaping up against Intel's own performance-optimized Clear Linux.

The PHP programming language's self-hosted Git server was compromised on Sunday and two malicious commits introduced...

Today's release of Linux 5.12-rc5 is "bigger than average" for this stage of kernel development and if that keeps up is likely to result in an extra week's worth of testing / an -rc8 release ahead of Linux 5.12 final, but it's too early to call at this stage...

While Godot receives much of the - well deserved - attention when it comes to open-source, cross-platform game engines, another deserving contender is the Flax Engine that just reached v1.0 last year after going public in 2018...

Last year we wrote how the X.Org/FreeDesktop.org cloud hosting costs were getting out of control so much so that they would either need to start finding sponsors and/or cut the continuous integration (CI) services offered to the hosted open-source projects, among other measures, as the costs were ballooning greatly. Thanks to a number of improvements to their hosting configuration, that is becoming a more manageable amount...

Launched last week with the AMD EPYC 7003 "Milan" processors was the AOCC 3.0 code compiler as AMD's downstream of LLVM Clang with various patches now catering to optimized for Zen 3. Last week some preliminary benchmarks of AOCC 3.0 on the Ryzen 9 5950X were carried out to good results. Since then I have begun putting AOCC 3.0 through its paces on a AMD EPYC 7003 series server to overall great results.

Panfrost has been the Gallium3D driver providing open-source OpenGL for Arm Mali Bifrost and Midgard GPus while now "PanVK" is in development as an open-source Vulkan driver...

While Intel is well known and loved for their generally very timely open-source hardware enablement under Linux, occasionally there are exceptions to that long-standing tradition of having the support squared away ahead of product launches. One of the areas where Intel has been slow at enabling their open-source Linux support is around their Gaussian and Neural Accelerator (GNA) but that driver is now coming together for being mainlined hopefully in the near future...

Besides Linux kernel developers still working to optimize code due to Retpolines overhead three years after Spectre rocked the ecosystem, another area kernel developers have still been actively working on is core scheduling for controlling the behavior of what software can share CPU resources or run on the sibling thread of a CPU core. That core scheduling work is finally closer to the mainline Linux kernel...

The Generic USB Display Driver "GUD" has just been sent in as part of the latest DRM-Misc-Next material to DRM-Next which in turn will land for Linux 5.13.
