With your search terms, you can compare against the same number of leading characters in each string with strncmp and output any matching lines (or store them, etc. Typing cat /proc/cpuinfo will display the contents of the file and all available information. If 64-bit is supported, you will get an output of 0 from the following command. Prior to running the remediation, dump out the cpuinfo by typing cat /proc/cpuinfo. In the x86-64 computer architecture, long mode is the mode where a 64-bit OS can access 64-bit instructions and registers. Where possible, this extra protection should be installed.

One of the cpu flags shows me that I support vmx but not the other.Another option is to pass the filename and terms to search for as arguments to the program rather than hardcode the filename and search terms. To check for 64-bit capability, we will need to check for the presence of the lm (Long Mode) flag. See Wikipedias article on x86 virtualization, for a list of. cat /proc/cpuinfo processor : 0 vendorid : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Pentium(R) 4 3.20GHz stepping : 10 microcode : 2571 cpu MHz : 2294.

Can someone explains to me why I'm running Ubuntu 10.10 kernel 2.6.35-24-generic. If such flag represents a hardware feature, it also means that the hardware supports it. I know that the file /proc/cpuinfo contains this information, in the flags line, but what do all these cryptic abbreviations mean For example, given the following extract from /proc/cpuinfo, do I have a 64-bit CPU Do I have hardware virtualization model name : Intel (R) Core (TM)2 Duo CPU E8400 3.00GHz. cat /proc/cpuinfo on my system gives me different flags for my 2 cores. In such cases, you should check your BIOS settings to enable VT support. In some CPU models, the VT support might be disabled in the BIOS, by default. If a given flag is present, it means that the kernel supports it and is currently making it available. To find the true architecture of the computer you can look for the lm flag in the list of flags in /proc/cpuinfo. Please note that these CPU flags (vmx or svm) in the /proc/cpuinfo file indicates that your system will support VT. Hello, what does at mean this flags in file 'cpuinfo' '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 constanttsc archperfmon pebs bts repgood nopl xtopology nonstoptsc aperfmperf.

I noticed this problem when trying to configure my system for KVM. If users want to know if a feature is available on a given system, they try to find the flag in /proc/cpuinfo.
