perf trace beauty: Add a x86 MSR cmd id->str table generator
Without parameters it'll parse tools/arch/x86/include/asm/msr-index.h
and output a table usable by tools, that will be wired up later to a
libtraceevent plugin registered from perf's glue code:
$ tools/perf/trace/beauty/tracepoints/x86_msr.sh
static const char *x86_MSRs[] = {
<SNIP>
[0x00000034] = "SMI_COUNT",
[0x0000003a] = "IA32_FEATURE_CONTROL",
[0x0000003b] = "IA32_TSC_ADJUST",
[0x00000040] = "LBR_CORE_FROM",
[0x00000048] = "IA32_SPEC_CTRL",
[0x00000049] = "IA32_PRED_CMD",
<SNIP>
[0x0000010b] = "IA32_FLUSH_CMD",
[0x0000010F] = "TSX_FORCE_ABORT",
<SNIP>
[0x00000198] = "IA32_PERF_STATUS",
[0x00000199] = "IA32_PERF_CTL",
<SNIP>
[0x00000da0] = "IA32_XSS",
[0x00000dc0] = "LBR_INFO_0",
[0x00000ffc] = "IA32_BNDCFGS_RSVD",
};
#define x86_64_specific_MSRs_offset 0xc0000080
static const char *x86_64_specific_MSRs[] = {
[0xc0000080 - x86_64_specific_MSRs_offset] = "EFER",
[0xc0000081 - x86_64_specific_MSRs_offset] = "STAR",
[0xc0000082 - x86_64_specific_MSRs_offset] = "LSTAR",
[0xc0000083 - x86_64_specific_MSRs_offset] = "CSTAR",
[0xc0000084 - x86_64_specific_MSRs_offset] = "SYSCALL_MASK",
<SNIP>
[0xc0000103 - x86_64_specific_MSRs_offset] = "TSC_AUX",
[0xc0000104 - x86_64_specific_MSRs_offset] = "AMD64_TSC_RATIO",
};
#define x86_AMD_V_KVM_MSRs_offset 0xc0010000
static const char *x86_AMD_V_KVM_MSRs[] = {
[0xc0010000 - x86_AMD_V_KVM_MSRs_offset] = "K7_EVNTSEL0",
<SNIP>
[0xc0010114 - x86_AMD_V_KVM_MSRs_offset] = "VM_CR",
[0xc0010115 - x86_AMD_V_KVM_MSRs_offset] = "VM_IGNNE",
[0xc0010117 - x86_AMD_V_KVM_MSRs_offset] = "VM_HSAVE_PA",
<SNIP>
[0xc0010240 - x86_AMD_V_KVM_MSRs_offset] = "F15H_NB_PERF_CTL",
[0xc0010241 - x86_AMD_V_KVM_MSRs_offset] = "F15H_NB_PERF_CTR",
[0xc0010280 - x86_AMD_V_KVM_MSRs_offset] = "F15H_PTSC",
};
Then these will in turn be hooked up in a follow up patch to be used by
strarrays__scnprintf().
