H A Dreg-file-data-sampling.rst2 Register File Data Sampling (RFDS)
5 Register File Data Sampling (RFDS) is a microarchitectural vulnerability that
6 only affects Intel Atom parts(also branded as E-cores). RFDS may allow
8 registers, vector registers, or integer registers. RFDS does not provide the
