--variant [1,2,3] specify which variant you'd like to check, by default all variants are checked,

can be specified multiple times (e.g. --variant 2 --variant 3)
|

--hw-only only check for CPU informations, don't check for any variant

--no-hw skip CPU information and checks, if you're inspecting a kernel not to be run on this host
