Linux Developers Ponder Decade-Old Decision To Disable PCI Runtime Power Management By Default

Back in 2010 was a change to disable run-time power management of PCI devices by default and leaving it up to user-space to in turn override it if desired. Now as we gear up for 2021, some upstream kernel developers are wondering about that original decision and possibly changing the default behavior to yield better out-of-the-box power savings with modern systems.

Loongson64 Finally Seeing KASLR With Mainline Linux 5.11 Kernel

While the Linux kernel has supported Kernel Address Space Layout Randomization (KASLR) for a decade and a half in varying forms, it hasn't been supported for all hardware targets. Only in 2021 is the mainline Linux kernel seeing KASLR working for the MIPS-based Loongson64 platform.
