Andreas Kling 4a8683ea68 Kernel+LibPthread+LibC: Add a naive futex and use it for pthread_cond_t ... This patch implements a simple version of the futex (fast userspace mutex) API in the kernel and uses it to make the pthread_cond_t API's block instead of busily sched_yield(). An arbitrary userspace address is passed to the kernel as a "token" that identifies the futex and you can then FUTEX_WAIT and FUTEX_WAKE that specific userspace address. FUTEX_WAIT corresponds to pthread_cond_wait() and FUTEX_WAKE is used for pthread_cond_signal() and pthread_cond_broadcast(). I'm pretty sure I'm missing something in this implementation, but it's hopefully okay for a start. :^)		2019-12-25 23:54:06 +01:00
