wRTOS HAL Extension

wRTOS extends, but does not modify, the Windows HAL by adding a real-time Subsystem (RTSS) that delivers deterministic, hard real-time performance. The HAL extension maintains interrupt isolation between RTSS and Windows and provides inter-processors interrupt (IPI) communication between them. It also includes a software interrupt mechanism between RTSS and Windows; basic exception management; system-normal shutdown and dump file support; high-resolution clocks and timers for RTSS (except when setting up RTSS processors/cores to run in IA-32e mode or 64-bit sub-mode); and enhancements for determinism.
