Table 2-27. More on Feature Information Returned in the EDX Register(Continued) Bit # Mnemonic Description INPUT EAX = 2: Cache and TLB Information Returned in EAX, EBX, ECX, EDX APPLICATION PROGRAMMING MODEL 20 Reserved Reserved 21 Debug Store. The processor supports the ability to write debug information into a memory resident buffer. DS This feature is used by the branch trace store (BTS) and precise event-based sampling (PEBS) facilities (see Chapter 17, “Debugging, Branch Profiles and Time-Stamp Counter,” in the Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 3A). 22 Thermal Monitor and Software Controlled Clock Facilities. The processor implements internal MSRs that allow ACPI processor temperature to be monitored and processor performance to be modulated in predefined duty cycles under software control. 23 MMX Intel MMX Technology. The processor supports the Intel MMX technology. 24 FXSAVE and FXRSTOR Instructions. The FXSAVE and FXRSTOR instructions are supported for fast save and FXSR restore of the floating-point context. Presence of this bit also indicates that CR4.OSFXSR is available for an operating system to indicate that it supports the FXSAVE and FXRSTOR instructions. 25 SSE SSE. The processor supports the SSE extensions. 26 SSE2 SSE2. The processor supports the SSE2 extensions. 27 SS Self Snoop. The processor supports the management of conflicting memory types by performing a snoop of its own cache structure for transactions issued to the bus. 28 HTT Multi-Threading. The physical processor package is capable of supporting more than one logical processor. 29 TM Thermal Monitor. The processor implements the thermal monitor automatic thermal control circuitry (TCC). 30 Reserved Reserved 31 Pending Break Enable. The processor supports the use of the FERR#/PBE# pin when the processor is in the PBE stop-clock state (STPCLK# is asserted) to signal the processor that an interrupt is pending and that the processor should return to normal operation to handle the interrupt. Bit 10 (PBE enable) in the IA32_MISC_ENABLE MSR enables this capability. When CPUID executes with EAX set to 2, the processor returns information about the processor’s internal caches and TLBs in the EAX, EBX, ECX, and EDX registers. The encoding is as follows: • The least-significant byte in register EAX (register AL) indicates the number of times the CPUID instruction must be executed with an input value of 2 to get a complete description of the processor’s caches and TLBs. The first member of the family of Pentium 4 processors will return a 1. • The most significant bit (bit 31) of each register indicates whether the register contains valid information (set to 0) or is reserved (set to 1). • If a register contains valid information, the information is contained in 1 byte descriptors. Table 2-28 shows the encoding of these descriptors. Note that the order of descriptors in the EAX, EBX, ECX, and EDX registers is not defined; that is, specific bytes are not designated to contain descriptors for specific cache or TLB types. The descriptors may appear in any order. Ref. # 319433-014 2-41
