GetCPUInfo()

Synopsis

void GetCPUInfo(
         struct TagItem * tagList );

void GetCPUInfoTags(
         TAG tag, ... );

Function

Provides information about selected processor in the system

Inputs

Function takes an array of tags. Data is returned for each tag. See
specific tag description. There is a control tag CGIT_SelecetProcessor.

Tags

GCIT_SelectedProcessor - (ULONG) When this tag is set correctly, information
                         about choosen processor is provided. If this
                         tag is missing or this tag has invalid value,
                         information about first processor is returned.

GCIT_NumberOfProcessors - (ULONG *) Provides the number of processors
                         present in the system.

GCIT_ModelString - (CONST_STRPTR *) Provides the name of the model of the
                    processor. The string is considered read-only.

GCIT_Family - (ULONG *) Provides designation of processor family using
              one of the CPUFAMILY_XXX values.

GCIT_VectorUnit - (ULONG *) Provides designation of available vectory
                  unit using one of the VECTORTYPE_XXX values.

GCIT_Architecture - (ULONG *) Provides designation of processor
                    architecture using one of the PROCESSORARCH_XXX
                    values.

GCIT_Endianness - (ULONG *) Provides designation of current processor
                  endianness using one of the ENDIANNESS_XXX values.

GCIT_ProcessorSpeed - (UQUAD *) Provides the current CPU speed in Hz

GCIT_FrontsideSpeed - (UQUAD *) Provides the current FSB speed in Hz

GCIT_ProcessorLoad - (UBYTE *) Provides the current CPU load in % (0-100)

Cache sizes - (ULONG *) Following tags are used to retrieve size of
              specified caches.

              GCIT_L1CacheSize
              GCIT_L1DataCacheSize
              GCIT_L1InstructionCacheSize
              GCIT_L2CacheSize
              GCIT_L3CacheSize

              Size is returned in kB.

GCIT_CacheLineSize - (ULONG *) Provides the size of cache line in bytes.
                     In case these sizes differ per cache level, the
                     smallest size if provided.

Features - (BOOL *) Following tags are used to check availability of
           certain features. The result is always a boolean.
