But acceleration code starts later than the class init of the board, meaning that tcg_enabled() will be always be false during class_init(), and the option is never being declared even when declaring TCG accel: $ ./build/qemu-system-riscv64 -M virt,accel=tcg,aclint=on qemu-system-riscv64: Property 'virt-machine.aclint' not found Fix it by moving the check from class_init() to machine_init(). Tune the description to mention that the option is TCG only.
