How is RTOS involved in running Linux on RISC-V?
Hi, Google explained that the two can coexist on a multi-core RISC-V with RTOS handling some hardware level tasks. For more verbiage, ask Google. TTFN, ... P.L. -- mobile: +1 778 951 5147 VoIP: +1 778 508 0020 Bcc: peter at e a s t h o p e dot c a projects: en.wikibooks.org/wiki/User:PeterEasthope

On http://oberon.wikidot.com/project-oberon-v, Peter Matthias explains that the "Same binary runs on Linux, 32 bit, Linux, 64 bit and FreeRTOS 64 bit on real hardware. Difference of the statically linked module is only for real hardware a 16 bit deep display is statically linked while on Linux display depth is 32 bit." (Which is very nice.) So these are alternatives rather than some fancy multi-OS setup, as far as I can see. HTH, Paul

If this is Google's automatic-idiocy bot, DO NOT TRUST IT. Never ever trust anything from an LLM bot. I have seen posts about a highly experimental Raspberry Pi OS experiment which ran NetBSD on one Arm core and RISC OS on another. However the thing is that the RasPi is not an Arm computer. It is a VideoCore running ThreadX with an Arm co-processor. So this technique might not scale. Also, Risc OS is inherently single-core so that makes life a tiny bit easier... two SMP OSes would be highly tricky. On a related note, I do not like Youtube, but this talk is highly relevant. https://www.youtube.com/watch?v=36myc8wQhLo https://www.usenix.org/conference/osdi21/presentation/fri-keynote Note -- he's from the same home as Oberon. -- Liam Proven ~ Profile: https://about.me/liamproven ~ LinkedIn/X/FB: lproven Email: lproven@cix.co.uk ~ Google: lproven@gmail.com IoM: (+44) 7624 227612: UK: (+44) 7939-087884 Czech [+ WhatsApp/Telegram/Signal]: (+420) 702-829-053
