Simply type the following command (this command provides lots of useful information including list of all features in human readable format): # cpuid. # cpuid less. # cpuid grep 'something'. Sample outputs: Fig.02: Linux cpuid Command To Dump CPUID information. On linux, you can read it using rdmsr (read model specific registers) On ubuntu, you could try something like the following: sudo apt-get install msr-tools sudo modprobe msr sudo rdmsr --bitfield 15:8 -c 0x00001a2 sudo rdmsr --bitfield 23:16 -c 0x00001a2. Returns 0x12 and 0x69 on my machine.

WebApr 3, 2024 · So we need to first read IA32_VMX_PROCBASED_CTLS using rdmsr and check if bit 63 is 1 or not. If the bit value is 1 then read IA32_VMX_PROCBASED_CTLS2 using the same command. The address for both the MSRs are as follows: IA32_VMX_PROCBASED_CTLS - 482H IA32_VMX_PROCBASED_CTLS2 - 48BH Command … WebFeb 15, 2016 · 02-16-2016 07:02 AM. 1,354 Views. Intel Performance Counter Monitor provides a C++ API to measure hardware counters, including energy consumption. It doesn't report the absolute temperature but the thermal headroom, i.e. the difference to the maximum temperature that the processor allows. Kind regards. drakeblue42
