Vitaly Buka via Libc-alpha Aug. 5, 2020, 4:30 p.m.
Intel64 and IA-32 Architectures Software Developer’s Manual has changed
the following CPU feature names:

1. The CPU feature of Enhanced Intel SpeedStep Technology is renamed
from EST to EIST.
2. The CPU feature which supports Platform Quality of Service Monitoring
(PQM) capability is changed to Intel Resource Director Technology
(Intel RDT) Monitoring capability, i.e. PQM is renamed to RDT_M.
3. The CPU feature which supports Platform Quality of Service
Enforcement (PQE) capability is changed to Intel Resource Director
Technology (Intel RDT) Allocation capability, i.e. PQE is renamed to
RDT_A.
