[$] Hazard pointers for the kernel

The kernel's read-copy-update (RCU) subsystem ensures that data will not be deleted until it is known that there are no threads holding references to it. RCU works well and is widely used throughout the kernel, but it can increase memory use and add significant delays before unused kernel objects are cleaned up. Hazard pointers are an alternative approach to lockless data updates that offers better performance, for some situations at least. The kernel community is currently considering a hazard-pointer implementation by Mathieu Desnoyers and Paul McKenney.

Mysterious 16-Tile & 32-Tile AMX Implementations Talked Up For More Performance

Last October on Phoronix we were first to point out there being some mysterious intrigue around a new x86 implementation from a "corporate entity other than Intel/AMD" with the developer involved not elaborating on the matter. Now that same developer has posted another semi-cryptic message to the Linux kernel mailing list to talk about 16-tile and 32-tile Advanced Matrix Extensions (AMX) implementations. To date Intel only has 8-tile AMX...

Framework Laptop 13 Pro: Aiming To Be One Of The Best Upgradeable Linux Laptops

Back in April, Framework Computer announced the Framework Laptop 13 Pro as a ground-up re-design of their modular/upgradeable laptop.
