PREEMPT-RT Locking Infrastructure Possibly Ready For Linux 5.15 - Phoronix
Six dozen patches working on the PREEMPT-RT locking infrastructure for real-time kernels is now queued up in TIP's "locking/core" branch and will presumably be sent in for the Linux 5.15 merge window coming up quickly.
These 72 patches are part of the Linux real-time (RT) work by Thomas Gleixner and others. This locking infrastructure work for real-time kernel builds is replacing mutex, ww_mutex, rw_semaphore, spinlock, and rwlock with RT-Mutex-based primitives. For non-real-time kernel builds there should be no functional changes with these locking changes.

Rather than just having per-CPU/core family targeting by the code compilers, over the past year the "x86-64 micro-architecture feature levels" have gained adoption as some common levels for both AMD and Intel processors to group CPU capabilities into a few tiers.
