We have covered some of the most common and salient flags in the /proc/cpuinfo file.Model name : Intel(R) Core(TM) i5-4210U CPU 1.70GHzįlags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid sse4_1 sse4_2 movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm epb tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid xsaveopt dtherm ida arat pln ptsĪddress sizes : 39 bits physical, 48 bits virtual Like the sse family in Intel, it enhances performance for heavy applications such as 3D animation, video processing, etc. sse4a: This stands for Streaming SIMD Extension 4.0.It helps map virtual addresses to physical addresses. abm: ABM is an acronym for Address Based Mapping.This is a floating point operation that combines multiplication and addition into a single instruction. fma: This stands for Floating Point Multiply Add.It enables the running of multiple threads on a single CPU core. lm: This is an abbreviation for Lockless Multithreading.The following are some of the common AMD flags. These provide support for fast multimedia applications. Sse4_1 and sse4_2 flags are an indicator that your CPU supports Streaming SIMD Extensions 4.1 and 4.2 respectively. It was tailored to enable operating systems to discover and configure hardware components.įor example, it abstracts the hardware layer and carries out basic power management tasks of devices attached to the system. This is an open standard originally developed by Microsoft, Intel, and Toshiba. The acpi flag stands for Advanced Configuration and Power Interface. ![]() By doing so, it prevents overheating which can cause damage to the CPU. This feature, as the name suggests, regulates the CPU temperature and keeps it at an optimal value by reducing its clock speed. The tm flag is an abbreviation for Thermal Cooling. This a feature that enhances the performance and efficiency of a system by allowing the CPU core to execute multiple threads in parallel. It enables the CPU to handle a large number of interrupts and by so doing, enhances dual processing and multi-processor support. It is a family of interrupt controllers that was developed by Intel and has been around since Intel Pentium. apicĪPIC is short for Advanced Programmable Interrupt Controller. It provides 13 new instructions and enhanced performance for 3D tasks and digital signal processing. ![]() Sse3 is also referred to as the Prescott New Instructions (PNI). In addition, it can simultaneously perform a single task across multiple pieces of data con. Unlike, the SSE2 has additional instructions and handles 64-bit values. This is basically an enhanced version of SSE. It comes in handy in process-intensive applications such as gaming, video and photo editing, 3D animation, and so on. It boosts the performance of a system via parallel processing. The sse flag (Streaming SIMD Extension) is an extension that is unique to Intel-based processors. It’s without a doubt a flag that features in modern operating systems given that a majority of them support huge RAM sizes based on the motherboard of the system. PAE, short for Physical Address Extension is a feature that permits CPUs to access RAM sizes greater than 4GB. For instance, it restricts access to specific memory locations or blocks the execution of code from certain sources. It’s an API that enforces security policies in Intel TXT platforms. The smx (Safer Mode Extensions) flag appears on 64-bit processors. You can achieve this using popular hypervisors such as VirtualBox and VMWare. ![]() The hypervisor flag proves that the CPU provides hardware support for running virtual machines. The presence of any of these flags indicates that Virtualization has been enabled on your PC or virtual machine and that you can install a hypervisor such as KVM, or VirtualBox to create virtual machines. On the other hand, svm (Secure Virtual Machine ) is the virtualization extension for AMD CPUs. This is a virtualization extension for the Intel CPU Processor. The vmx flag stands for Virtual Machine Extension.
