Allow allocating more CPU/memory #9

Open Eeems opened 11 months ago

Eeems commented 11 months ago

It would be useful if the run_vm.sh script allowed overriding the cpu core count and the memory allocation. Automated build processes using this image would benefit from more resources.

Honestly, for CPU intensive work, it might be worth setting up user mode qemu emulation. The system mode emulation is heavy, but allows us to run xochitl easily. The SOC is limited to 2 cores, so enabling more won't be possible without changing SOCs.

https://www.qemu.org/docs/master/user/main.html + a sysroot (maybe even from the official sdk). Or something like https://github.com/tonistiigi/binfmt to auto-run qemu user mode in a docker container might be a better solution

The user mode branch now has a qemu-user target that uses user mode emulation (see Readme). toltec doesn't install though:

Using systemd as the init is required for toltec to work, as it's heavily assumed in most of the packages.
