CPUID Interface

Each Intel® XED ISA-SET can be mapped to one or more CPUID groups (feature bit, Intel® AVX10...) and each CPUID group is mapped to one or more CPUID records. For each ISA-SET, the CPUID scan should accrue in two nested loops; by iterating through all ISA-SET's CPUID groups and by iterating through all group's CPUID records. For more usage example, please check the xed-ex1.c example (Small Examples of using Intel® XED). More...

Function Documentation

xed_get_cpuid_group_enum_for_isa_set()

XED_DLL_EXPORT xed_cpuid_group_enum_t xed_get_cpuid_group_enum_for_isa_set	(	xed_isa_set_enum_t	isaset,
		xed_uint_t	i
	)

Returns the name of the i'th cpuid group associated with the given isa-set. This function is called repeatedly, with i = 0 until reaching XED_MAX_CPUID_GROUPS_PER_ISA_SET or when the return value is XED_CPUID_GROUP_INVALID. An ISA-SET is supported by a chip if CPUID match is found for a single CPUID group (OR relationship between groups).

xed_get_cpuid_rec()

XED_DLL_EXPORT xed_bool_t xed_get_cpuid_rec	(	xed_cpuid_rec_enum_t	cpuid_bit,
		xed_cpuid_rec_t *	p
	)

provides the details of the CPUID specification, if the enumeration value is not sufficient. stores the values of the CPUID record in the given pointer p

Returns

xed_bool_t 1=success , 0=failure

xed_get_cpuid_rec_enum_for_group()

XED_DLL_EXPORT xed_cpuid_rec_enum_t xed_get_cpuid_rec_enum_for_group	(	xed_cpuid_group_enum_t	group,
		xed_uint_t	i
	)

Returns the name of the i'th cpuid record associated with the given cpuid group. This function is called repeatedly, with i = 0 until reaching XED_MAX_CPUID_RECS_PER_GROUP or when the return value is XED_CPUID_REC_INVALID. A cpuid group is satisfied if all of its cpuid records are set (AND relationship between records).
