The futex mechanism provided by the kernel allows for the creation of efficient and flexible locking primitives in user space. Futexes work well for many applications, but not all. One of the ...

Interrupt locking (disabling system interrupts) is the method used to synchronize exclusive access to shared resources between tasks and ISRs. Some processor architecture designs allow for a ...

This two-part series addresses the use and misuse of two of the most essential synchronization primitives in modern embedded systems, the mutex (this part) and the semaphore (part 2). Mutexes and ...

Wine already has a solution to this problem; it's just excessively slow because it depends on relatively complex user-space emulation of a kernel primitive, where the wineserver process does a lot of ...
