Flags do not appear by default in /proc/cpuinfo ¶ Feature flags are omitted by default from /proc/cpuinfo as it does not make sense for the feature to be exposed to userspace in most cases. For example, X86_FEATURE_ALWAYS is defined in cpufeatures.h but that flag is an internal kernel feature used in the alternative runtime patching functionality.

This article will explain how to read cpuinfo information in Linux. Later, we will examine what CPU flags are and their meanings. Read cpuinfo There are situations in which overriding the displayed name of the flag is needed. For instance, /proc/cpuinfo is a userspace interface and must remain constant. If, for some reason, the naming of X86_FEATURE_ changes, one shall override the new naming with the name already used in /proc/cpuinfo.

Learn about the /proc/cpuinfo file in Linux, the different sections inside it, more about its flags, and how to use it to write shell scripts. If plain text is not your thing, utilities like lscpu format /proc CPU data into a very readable output. But here you‘re just getting a prettified makeover of the same underlying /proc goods. Fun fact – on my benchmark box, /proc/cpuinfo unpacks into over 300 lines spanning 13k when outputting the full feature set!

Understanding Linux /proc/cpuinfo hyperthreaded processor has the same number of function units as an older, non-hyperthreaded processor. It just has two execution contexts, so it can maybe achieve better function unit utilization by letting more than one program execute concurrently. On the other hand, if you’re running two programs which compete for the same
