cpu_raw_data_t(3)

NAME
cpu_raw_data_t - Contains just the raw CPUID data.

SYNOPSIS

#include <libcpuid.h>

  Data Fields
uint32_t basic_cpuid [MAX_CPUID_LEVEL][NUM_REGS]
uint32_t ext_cpuid [MAX_EXT_CPUID_LEVEL][NUM_REGS]
uint32_t intel_fn4 [MAX_INTELFN4_LEVEL][NUM_REGS]
uint32_t intel_fn11 [MAX_INTELFN11_LEVEL][NUM_REGS]
uint32_t intel_fn12h [MAX_INTELFN12H_LEVEL][NUM_REGS]
uint32_t intel_fn14h [MAX_INTELFN14H_LEVEL][NUM_REGS]
uint32_t amd_fn8000001dh [MAX_AMDFN8000001DH_LEVEL][NUM_REGS]

Detailed Description

Contains just the raw CPUID data. This contains only the most basic CPU data, required to do identification and feature recognition. Every processor should be identifiable using this data only.
