cat /proc/cpuinfo and look for the physical address size. The field cpuid level should return the highest non-extended cpuid leaf (i.e. To verify whether the the CPU is affected, run the following command from the. You can easily find this information by visiting /proc/cpuinfo file.
Cat proc cpuinfo virtual address full#
However, /proc/cpuinfo reports that the processor supports only 36-bit physical addressing (though the full 48-bit virtual). // Inquiring cpu cores cat /proc/cpuinfo processor : 0 vendorid : GenuineIntel cpu family : 6 model : 45 model name : Intel(R) Xeon(R) CPU E5-2660 0 2.20GHz stepping : 6 microcode : 1561 cpu MHz : 600.000 cache size : 20480 KB physical id : 0 siblings : 16 core id : 0 cpu cores : 8 apicid : 0 initial apicid : 0 fpu : yes fpuexception : yes cpuid level : 13 wp : yes flags : fpu vme de pse. processor : 0 vendorid : GenuineIntel cpu family : 6 model : 158 model name : Intel (R. The output is very detailed where following information is provided. As a simple text file echo command can be used to print CPU information via the /proc/cpuinfo. eax is the physical address size in bits eax is the virtual address size. Most of the commands related to CPU info get information from this file. vsize lu (23) Virtual memory size in bytes. The address sizes supported by the processor are found in leaf 0x80000008. Since Linux 2.6, the value is expressed in clock ticks (divide by sysconf(SCCLKTCK)). In /proc/cpuinfo, however, the apicid and initial apicid fields are listed as 0 for every single logical core. Running the cpuid instruction on each core in turn, I have local APIC IDs of 0x00 through 0x0f, and similarly, extended APIC IDs of 0x00 through 0x0f. On AMD chips, such as mine, it's in leaf 0x8000001e, eax. address sizes : 40 bits physical, 48 bits virtual power management: m1.xlarge (vCPU:4, ECU:8) cat /proc/cpuinfo processor : 0 vendorid : GenuineIntel cpu family : 6 model : 45 model name : Intel(R) Xeon(R) CPU E5-2650 0 2.00GHz stepping : 7 microcode : 0x70a cpu MHz : 1799. In common with other modern processors, the cpuid instruction reports two APIC IDs the local APIC ID in leaf 0x1, ebx, and then the extended or x2 APIC ID in Intel chips this is in leaf 0xb. I have an AMD Ryzen 7 1700X processor (8 core/16 thread). Can someone explain to me some probable reasons behind this cat /proc/cpuinfo grep -i 'cpu Mhz' cpu MHz : 0.000 cpu MHz : 0.000 cpu MHz : 0.000 cpu MHz : 0. It is a physical host with no virtualization. It should be enumerating the properties of my CPU. I saw an interesting issue where the cpuinfo file from /proc filesystem shows the cpu clock speed as zero. For a 64-bit virtual address, it is 248, that is, 48 bits are used to represent the virtual. What's wrong / what should be happening instead: Is the address space of 264 at this time This is not true. What you're doing and what's happening: (Copy&paste specific commands and their output, or include screen shots)
Cat proc cpuinfo virtual address code#
Your Windows build number: (Type ver at a Windows Command Prompt) The CPU you see in /proc/cpuinfo is one of the available emulation settings, see target-i386/cpu.c in the source code and the output of qemu-system-x8664 -cpu help it doesn't correspond to the underlying CPU (which would report a specific model, not 'E312xx').
