Andreas Kling fdfc66db61 Kernel+LibC: Allow clock_gettime() to run without syscalls ... This patch adds a vDSO-like mechanism for exposing the current time as an array of per-clock-source timestamps. LibC's clock_gettime() calls sys$map_time_page() to map the kernel's "time page" into the process address space (at a random address, ofc.) This is only done on first call, and from then on the timestamps are fetched from the time page. This first patch only adds support for CLOCK_REALTIME, but eventually we should be able to support all clock sources this way and get rid of sys$clock_gettime() in the kernel entirely. :^) Accesses are synchronized using two atomic integers that are incremented at the start and finish of the kernel's time page update cycle.		2021-08-10 19:21:16 +02:00
