One has to wonder how much longer the Linux kernel will keep around some very old and known to be borked hardware support but at least for now the DECpc AXP 150 "Jensen" platform support is sticking around and with Linux 5.15 is no longer marked as "broken" outright...

BayLibre developer Alexandre Bailon has posted a "request for comments" of a new open-source Direct Rendering Manager (DRM) driver for AI Processing Unit (APU) functionality.

As speculated at that time, their work would likely revolve around use of ACPI CPPC found with Zen 2 CPUs and newer. Published last week was that AMD P-State driver for Linux systems indeed now leveraging CPPC information. AMD formally presented this new driver yesterday at XDC2021...

Those reading Phoronix over the years likely know the X.Org Server has had an increasing number of vulnerabilities come to light in recent times and statements by security researchers like the security being even worse than it looks. Given the age of the X.Org/X11 codebase and many components being rather unmaintained these days, the security situation isn't that great combined with a lack of manpower. The security topic was under the spotlight today at the XDC2021 conference...

Following the big OpenZFS 2.1 release from July that brought Distributed SPARE RAID, a compatibility property for pools, and other new features, OpenZFS 2.1.1 is available today as a follow-up release for this open-source ZFS file-system implementation for Linux and FreeBSD systems...

As usual when the Linux 5.15 merge window began wrapping up, I set out to dive into its performance to see what is in store for this next version of the kernel and whether there was any regressions or other performance changes worth noting. Linux 5.15 overall has been in good shape for the "-rc1" state except noticing that code compilation workloads were taking longer on multiple Linux 5.15-rc1-running systems than Linux 5.14 or prior. Seeing it across multiple systems and a very real-world regression, it was worth bisecting and looking closer so here are the details.

With the Linux 5.15 merge window out of the way, the first drm-misc-next pull request has been sent in to DRM-Next for staging until the Linux 5.16 merge window opens up about two months from now...

While NVIDIA has been supporting Resizable BAR for a while now with their GeForce RTX 30 series graphics cards, for those exclusively using Linux it remains more of a challenge due to AIB partners generally not releasing any vBIOS updates for ReBAR support that can be easily applied under Linux. But if you do carry out an update -- such as under Windows -- the performance uplift can be worthwhile if using a game that can benefit from the support.

"Intel Seamless Update" is a forthcoming feature for Intel platforms seemingly first being exposed by their new Linux kernel patches working on the functionality...
