    en.wikipedia.org/wiki/RTLinux

    RTLinux is a hard realtime real-time operating system (RTOS) microkernel that runs the entire Linux operating system as a fully preemptive process. The hard real-time property makes it possible to control robots, data acquisition systems, manufacturing plants, and other time-sensitive instruments and machines from RTLinux applications.

    en.wikipedia.org/wiki/PREEMPT_RT

    PREEMPT_RT was a set of patches for the Linux kernel which implement both hard and soft real-time computing capabilities. [1] On September 20, 2024, PREEMPT_RT was fully merged and enabled in mainline Linux on the supported architectures x86, x86_64, RISC-V and ARM64. [2] This will make kernel v6.12 the first release to include baked-in real ...

  7. Real-time operating system - Wikipedia

    en.wikipedia.org/wiki/Real-time_operating_system

    A real-time operating system (RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints. An RTOS like Linux is distinct from a time-sharing operating system, such as Unix , which manages the sharing of system resources with a scheduler, data buffers, or ...

    en.wikipedia.org/wiki/Year_2038_problem

    FreeBSD uses 64-bit time_t for all 32-bit and 64-bit architectures except 32-bit i386, which uses signed 32-bit time_t instead. [23] The x32 ABI for Linux (which defines an environment for programs with 32-bit addresses but running the processor in 64-bit mode) uses a 64-bit time_t. Since it was a new environment, there was no need for special ...
