[β] henfredemars@infosec.pub 24 points 1 year ago (2 children) Pretty much the only place it doesnβt run is where you have hard real-time requirements and on extremely small embedded micro controllers. permalink fedilink source parent hideshow 4 child comments replies: [β] DmMacniel@feddit.org 21 points 1 year ago (2 children) But isn't there a RTOS Linux kernel? permalink fedilink source parent hideshow 4 child comments replies: [β] Colloidal@programming.dev 19 points 1 year ago* (1 child) Technically yes. But it can't support many hard real-time use cases. For that you need a true RTOS, thought from the ground up for that purpose. Something like VxWorks, QNX, some flavors of L4. permalink fedilink source parent hideshow 2 child comments replies: [β] DmMacniel@feddit.org 4 points 1 year ago (2 children) I miss QNX. permalink fedilink source parent hideshow 4 child comments replies: [β] DeltaWingDragon@sh.itjust.works 4 points 1 year ago It's still around. The latest release (8.0) is free-as-in-beer for non-commercial use. It's still proprietary though. permalink fedilink source parent [β] Colloidal@programming.dev 2 points 1 year ago Only ever interacted with 6.0 beta. It was a great microkernel system. Even its GUI, Photon, was of a microkernel design, each module operating as a separate process. And it looked so good. permalink fedilink source parent [β] henfredemars@infosec.pub 14 points 1 year ago Sort of. There's realtime builds, but the Linux definition of real time is more relaxed than dedicated RTOS's in exchange for a much more feature-filled OS. You should not use Linux if people could die when you miss a deadline. You want a simple system where it's easier to prove that can never happen. permalink fedilink source parent [β] thepreciousboar@lemm.ee 3 points 1 year ago I believed the kinux kernel recently became real time? permalink fedilink source parent
