Assuming the specs I found are correct and they are full
cores, there should be no issue using hw.smt=1 to enable
the others on this machine as was suggested by others.
There might be some quirk in how the cpu returns information
about cores that means that they're detected as threads
instead of full cores.
Please show dmesg, and output from lscpu (in packages).
Maybe there is some more we could do to detect it better,
or maybe this model just reports strangely for the relevant
cpuid instructions.
