1config BR2_PACKAGE_MSR_TOOLS 2 bool "msr-tools" 3 depends on BR2_i386 || BR2_x86_64 4 help 5 The MSR Tools project provides utilities to access x86 6 processor MSRs and CPU ID directly. 7 8 Those tools access the hardware through the 9 /dev/cpu/<cpu#>/msr and /dev/cpu/<cpu#>/cpuid devices. This 10 necessitates msr and cpuid support in the kernel, which 11 means you need a kernel compiled with configuration options 12 CONFIG_X86_CPUID and CONFIG_X86_MSR enabled. 13 14 https://01.org/msr-tools 15
