I don't think you want to enable it by default for everyone. The riscv
defconfig sets CONFIG_PREEMPT_NONE=y by default. For testing you need to
flip this to CONFIG_PREEMPT_RT=y and since CONFIG_EXPERT=y is already
set this option is available.
And yes, it works on the virt board and there is no wizardry needed ;)
