'''RTLinux''' is a [[hard realtime]] [[real-time operating system]] (RTOS) [[microkernel]] that runs the entire [[Linux]] [[operating system]] as a fully [[preemption (computing)|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. The design was patented.<ref name="RTLinux Patent">{{cite web |last1=yodaiken |first1=victor |title=Adding real-time support to general purpose operating systems |url=https://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=5,995,745.PN.&OS=PN/5,995,745&RS=PN/5,995,745 |website=USPTO |publisher=USPTO |access-date=19 January 2022 |ref=RTLPATENT}}</ref> Despite the similar name, it is not related to the [[Real-Time Linux]] project of the [[Linux Foundation]].<ref>{{cite web|url=https://wiki.linuxfoundation.org/realtime/start|title=realtime:start [Linux Foundation Wiki]|website=wiki.linuxfoundation.org}}</ref>

RTLinux was developed by Victor Yodaiken, Michael Barabanov, Cort Dougan and others at the [[New Mexico Institute of Mining and Technology]] and then as a commercial product at FSMLabs. [[Wind River Systems]] acquired FSMLabs embedded technology in February 2007 and made a version available as Wind River Real-Time Core for [[Wind River Linux]]. As of August 2011, Wind River has discontinued the Wind River Real-Time Core product line, effectively ending commercial support for the RTLinux product.
