func NumPhysicalPackages

func NumPhysicalPackages(cpuInfo *ghwcpu.Info) int

"The kernel does not care about the concept of physical sockets because a socket has no relevance to software. It’s an electromechanical component. In the past a socket always contained a single package (see below), but with the advent of Multi Chip Modules (MCM) a socket can hold more than one package. So there might be still references to sockets in the code, but they are of historical nature and should be cleaned up." -- https://www.kernel.org/doc/html/v5.9/x86/topology.html#x86-topology

Types

type Info

type Info struct {
	ghwcpu.Info
	// TotalPackages is the total number of physical packages the host system
	// contains
	TotalPackages uint32 `json:"total_packages"`
	// CurrentFrequency is the processor Frequency in KHz when the information was
	// gathered. On multi-core and multi-package system this value is meaningless.
	CurrentFrequency uint32 `json:"current_frequency"`
}
