[PATCH 0/4] drivers core: Introduce CPU type sysfs interface

2020-10-02 Thread Ricardo Neri
Hybrid CPU topologies combine processors with more than one type of micro-architecture. Hence, it is possible that individual CPUs support slightly different features (e.g., performance counters) and different performance properties. Thus, there may be user space entities interested in knowing the
