- I'm interested in the algorithms used to provide readers/writer synchronisation
- in SMP operating systems such as SVR4/MP, SunOS 5.0, Mach etc.
-
- Both SVR4/MP and SunOS 5.0 provide primitives to allow concurrent reads and exclusive
- writes for a shared resource. How are these implemented on 80x86s, SPARC etc? Does
- Mach provide them?
