Hi Varun,

Memory footprint will be a function of three build-time constants: MAX_CPUS, MAX_VMS and HEAP_PAGES. They're defined in the build rule of each target platform, e.g. for RPi4 it is here: https://git.trustedfirmware.org/hafnium/project/reference.git/tree/BUILD.gn#...

Hope this helps, David

Hi,

We are trying to figure out the memory footprint (.text + .data) for the Hafnium image. I couldn't find a place where the number of CPUs are specified for a platform. I assume that the footprint will increase as we introduce more CPUs in the mix.

Can someone please help me figure this out?

Thanks.
