INPUT EAX = 10: Returns Architectural Performance Monitoring Features APPLICATION PROGRAMMING MODEL When CPUID executes with EAX set to 10, the processor returns information about support for architectural performance monitoring capabilities. Architectural performance monitoring is supported if the version ID (see Table 2-23) is greater than Pn 0. See Table 2-23. For each version of architectural performance monitoring capability, software must enumerate this leaf to discover the programming facilities and the architectural performance events available in the processor. The details are described in Chapter 17, “Debugging, Branch Profiles and Time-Stamp Counter,” in the Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 3A. INPUT EAX = 11: Returns Extended Topology Information When CPUID executes with EAX set to 11, the processor returns information about extended topology enumeration data. Software must detect the presence of CPUID leaf 0BH by verifying (a) the highest leaf index supported by CPUID is >= 0BH, and (b) CPUID.0BH:EBX[15:0] reports a non-zero value. INPUT EAX = 13: Returns Processor Extended States Enumeration Information When CPUID executes with EAX set to 13 and ECX = 0, the processor returns information about the bit-vector representation of all processor state extensions that are supported in the processor and storage size requirements of the XSAVE/XRSTOR area. See Table 2-23. When CPUID executes with EAX set to 13 and ECX = n (n > 1and less than the number of non-zero bits in CPUID.(EAX=0DH, ECX= 0H).EAX and CPUID.(EAX=0DH, ECX= 0H).EDX), the processor returns information about the size and offset of each processor extended state save area within the XSAVE/XRSTOR area. See Table 2-23. METHODS FOR RETURNING BRANDING INFORMATION Use the following techniques to access branding information: 1. Processor brand string method; this method also returns the processor’s maximum operating frequency 2. Processor brand index; this method uses a software supplied brand string table. These two methods are discussed in the following sections. For methods that are available in early processors, see Section: “Identification of Earlier IA-32 Processors” in Chapter 14 of the Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 1. The Processor Brand String Method Figure 2-5 describes the algorithm used for detection of the brand string. Processor brand identification software should execute this algorithm on all Intel 64 and IA-32 processors. This method (introduced with Pentium 4 processors) returns an ASCII brand identification string and the maximum operating frequency of the processor to the EAX, EBX, ECX, and EDX registers. Ref. # 319433-014 2-45
APPLICATION PROGRAMMING MODEL How Brand Strings Work CPUID IF (EAX & 0x80000000) CPUID Function Supported Input: EAX= 0x80000000 True ≥ Extended EAX Return Value = Max. Extended CPUID Function Index IF (EAX Return Value ≥ 0x80000004) False True Processor Brand String Not Supported Processor Brand String Supported OM15194 Figure 2-5. Determination of Support for the Processor Brand String To use the brand string method, execute CPUID with EAX input of 8000002H through 80000004H. For each input value, CPUID returns 16 ASCII characters using EAX, EBX, ECX, and EDX. The returned string will be NULL-terminated. Table 2-30 shows the brand string that is returned by the first processor in the Pentium 4 processor family. 2-46 Ref. # 319433-014
