Cache Size : 12288 KB : CPU Level two cache size
Physical ID: 1 : Starting from 0, stating that my server has two physical CPUs
Siblings:12 Logical physical cores per CPU
Core ID : Ten : The number of the current physical core in which the CPU is located, which is not necessarily contiguous
CPU Cores : 6 : The physical core number of the CPU at which the logical core is located
Apicid : : Used to distinguish between different logic and the number, each logical and this number is different, not necessarily continuous
Initial Apicid : :
FPU : Yes : Whether a floating-point unit is in operation
fpu_exception : Yes : Whether floating point calculation exceptions are supported
CPUID Level : One : The value in the EAX register before the CPUID instruction, and different CPUID instructions will return different content
