AMD P-State Tracer Tool To Be Included With Linux 5.18
One of the most prominent additions to the Linux 5.17 kernel is the introduction of the AMD P-State driver akin to Intel's P-State driver and aims to deliver better energy efficiency than AMD Zen 2 and newer processors currently on the ACPI CPUFreq driver. With Linux 5.18 an AMD P-State tracer tool is to be included with the kernel source tree for helping to analyze and tune this new driver...

The Performance Impact Of AMD Changing Their Retpoline Method For Spectre V2
Made public this week was the Spectre-BHB / BHI vulnerability and while only Intel and Arm processors are currently believed to be impacted, in the course of that research the folks at VUSec discovered AMD's current Retpoline strategy for Spectre V2 mitigations is not adequate. This has led to a change in behavior for AMD processors and is already applied to the Linux kernel. Here is a look at what it means for desktop and server performance due to the change in return trampoline handling.
AMD "EFC" Support Added To Mesa 22.1 For Radeon GPUs With VCN 2.0
For AMD Navi "RDNA1" GPUs and newer having at least Video Core Next 2.0 (VCN2) for the video coding block, a new feature was merged today into Mesa 22.1-devel for the open-source AMD video acceleration stack...
Linux 5.18 To Bring New Intel Drivers, Optimization For AMD EPYC, C11 & Much More
Linux 5.17 will hopefully be released on Sunday and with that next kernel there are many exciting features in tow. But for as great as Linux 5.17 is, there are many features I am already eager for with Linux 5.18. Here is an early look at a number of the changes expected in this next kernel version...

Linux Plans To Stop Building a.out Support On Alpha & M68k To See If Anyone Cares
Back in 2019 that seems like an eternity ago with all that's gone on in the world, the Linux kernel deprecated a.out support. This executable / object code / shared library file format was used prior to the dominance of ELF but is seldom if ever used today. There have been pending patches to finally remove a.out from the kernel while the plan now is to stop building it on Alpha and Motorola 68000 targets to see if anyone notices/cares...

In Light Of Spectre BHI, The Performance Impact For Retpolines On Modern Intel CPUs
Made public on Tuesday was BHI / Spectre-BHB as the newest offshoot from Spectre V2. There were Linux patches immediately posted for affected Intel and Arm processors while also making adjustments to AMD CPUs around its Retpoline handling. The VUSec security researchers that discovered BHI are recommending Retpolines be enabled for newer processors even those with hardware mitigations against Spectre V2, but that's that performance cost? Here are some initial benchmarks.
AMD Posts New Linux Code For Zen 4's UAI Feature
