Name

arch_match_cpu_phys_id — match the given logical CPU and physical id

Synopsis

bool arch_match_cpu_phys_id (int cpu,
 u64 phys_id);
 

Arguments

cpu

Logical cpu index of a core/thread

phys_id

Physical identifier of a core/thread

Description

CPU logical to physical index mapping is architecture specific. However this __weak function provides a default match of physical id to logical cpu index. phys_id provided here is usually values read from the device tree which must match the hardware internal registers.

Return

True if the physical identifier and the logical cpu index correspond to the same core/thread, false otherwise.
