The real-time "RT" mainlining effort for the Linux kernel remains ongoing. While the finish line is coming near, PREEMPT_RT support for mainline still isn't over the last hurdle -- seemingly the main blocker it's still held up by are the printk changes with threaded console printing. But for the Linux 6.1 merge window there is at least more kernel code clean-ups...

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.
