What's wrong with the > existing set of machine names? Zoltan and you don't want to add more machine names, then you don't want a generic machine. This is very confusing.

See previous patch: $ qemu-system-aarch64 -M raspi,model=help Available models (processor): - A (BCM2835) - B (BCM2835) - A+ (BCM2835) - B+ (BCM2835) - CM1 (BCM2835) - Zero (BCM2835) - ZeroW (BCM2835) - 2B (BCM2836) - 3B (BCM2837) - CM3 (BCM2837) - 3B+ (BCM2837) - 3A+ (BCM2837) - CM3+ (BCM2837) - 4B (BCM2838) Can we or not add the other raspi models? > Can we implement "support more than just the fixed amount > of RAM" by making '-m 2G' work, without changing the > machine names at all, please? We surely can if we find developers motivated to do the work. Regards, Phil.
