I always love pull requests that start off with "there's a bunch of performance improvements..." as is the case with the new Btrfs feature pull for Linux 6.1...

Last week I shared some initial numbers how surprisingly when disabling Zen 4 CPU security mitigations can actually *hurt* the Ryzen 7000 series CPU performance. While conventional wisdom and with past Intel/AMD processors yield better performance when disabling the CPU security mitigations, with the Ryzen 9 7950X it was found to be basically the opposite. I have since conducted more tests and using an AMD Ryzen 5 7600X to confirm the earlier results and dig deeper into the data.

A kernel hardening security improvement on the way for Linux 6.1 is the ability to provide warning of possible memcpy() based overflows. Right now this is only a warning but it's work towards being able to address "trivially detectable" buffer overflow conditions within the kernel and in the future may be able to block such overflows from happening...

Before getting busy with the AMD Ryzen 7000 "Zen 4" desktop testing, I recently wrapped up some benchmarks looking at the ACPI CPUFreq vs. AMD P-State frequency scaling drivers and various governor options for the AMD Ryzen 6000 "Rembrandt" mobile SoCs. If you are curious about the impact of CPUFreq/P-State and the various governors for the latest AMD laptops running Linux, this round of testing is for you.

Lyra makes use of machine learning and other techniques for extremely low bit-rate speech compression that can function at 3kbps. Google last year open-sourced the Lyra code while today they announced the availability of Lyra V2...

While some Linux enthusiasts eagerly recommend users boot their systems with the "mitigations=off" kernel parameter for run-time disabling of various relevant CPU security mitigations for Spectre, Meltdown, L1TF, TAA, Retbleed, and friends, with the new AMD Ryzen 7000 "Zen 4" processors while still needing some software mitigations, it's surprisingly faster for the most part leaving the relevant mitigations enabled...

Currently Linux's Logitech HID++ driver "hid-logitech-hidpp" relies on a static list of device quirks for indicating which Logitech mice support high resolution scrolling. With the upcoming Linux 6.1 kernel, the plan is to change that list of devices/quirks and to automatically determine if a device supports high resolution scrolling...
