Thanks everyone. I got authorized to continue my effort, and I was looking into what is currently available.
I don't have to worry about red/black channels for now, so confidentiality is not yet a priority. My main priority is to create a steel thread so that if the main operating system crashes, a giant robotic vehicle can be teleoperated or shutdown without hurting anyone. I saw that Neutrality-CH (Switzerland) had forked the Microkit library for x86 (https://github.com/Neutrality-ch/microkit), but they had only made two commits, the last one was in December 17. I tried to contact them a few weeks ago, but I didn't hear back so I'm not sure the status/funding of their project. Anyway, currently the VMM capabilities are not developed for their fork which would make deployment of an OS tedious. At first glance, it looks like I need to put some work into building a VMM into their fork by studying and then calling the seL4 vcpu, interrupt, x86_src routines into their Microkit fork? I guess my question now as I parse through everything. Is the Neutrality-CH fork the best, most recent x86 fork of the microkit? Or is there another library/fork I should consider for development? I saw that their approach for pre-generating an ELF file for the bootloader was the main obstacle for their pull request, but since I'm working on a specific Intel architecture (8th gen, uses Intel VT-x and VT-d for virtualization), I can avoid over generalizing my solution and focus on this specific application. Is there any value in extracting/porting the work performed in CAmkES x86 virtualization for the microkit x86 fork? Thanks again for all the help! -Peter ________________________________ The information contained in this e-mail and any attachments from Intellisense Systems may contain confidential and/or proprietary information, and is intended only for the named recipient to whom it was originally addressed.
