multicore support present? #4

Hi, Does qbox in its current stage support multi-core emulation. For example: like cortex a53 + cortex a76 combined to run the sample ubuntu image on top of platform-vp.

Short answer - yes. (In the case of a53 + a76 you can even share the same Qemu instance, but you can equally have multiple Qemu instances - that would allow you to have different router's for the different address spaces)

Thank you for the quick response. I have made some changes in the conf.lua file but it seems to be using only single core (a53 in my case). attaching the lua file for reference. conf.txt

you seem to have flipped cpu_0 and _1, and you probably need to take some care with the GIC, not sure that part of the file won't actually just overwrite itself. You can also try having a new QEMU instance, but I think it should work the way you have it.

Correct me if I'm wrong but. I tried booting up with the conf.lua mentioned previously. The lscpu command is showing only one CPU (Cortex A76) as seen:

I am not sure what could be the reason as to why Cortex A53 is not listed.
