Hi everyone, I am a PhD student. For my research, I want to use sel4 and developa system based on it. The idea is to use the arm based multi VM and cross VM communication ability of sel4 and provide a secure and isolated environment for the various applications running on the system. I was reading through the sel4 tutorials and documentation to find out which hardware would be suitable for this. I started learning sel4 with Raspberry Pi 3, but as Rpi3 does not have GICv2 or GICv3, I am not sure how do I develop the CAmkES-arm-vmm,  multi VM and cross VM connector on it. As I wish to develop an application i.e a system architecture using sel4, itwould be good to have a device that provides me the starting point of having a multi VM and Cross VM communication. I read in the documentation that we can use Nvidia TK1-SOM from Colorado engineering to develop CAmkES-arm-vmm. But if I see the table here: _https://docs.sel4.systems/projects/camkes-arm-vm/_ , it says that CrossVM and Multi VM support is unsupported and in notes it says untested. According to the table, this is true for TK1, TX1 and TX2. Could someone please clarify what does this mean? Does it mean that we cannot have these features for these hardware or is it that they are not tested? It will be a great help to get this information, as then I can purchase the correct hardware and advance my work. I am new to micro-kernel community, so I apologize if I have missed anything obvious and would be glad to receive guidance and advice. Hoping for a kind response. Thank you. Sincerely, Zohra
