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...

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...
