**Table 1** Parameters of the **cpu** command
Parameter	Option	Description
None	-	Collects all CPU information.
-h/--help	-	Obtains help information.
-G/--general	-	Displays basic CPU information.
-c/--cpu	n n,m n-m all	Displays detailed information about a specified CPU core. The number of CPU cores is dynamically displayed based on the actual environment. The following provides an example of parameters: To collect information about CPU core 1, enter -c 1. To collect information about CPU cores 0 and 2, enter -c 0,2. To collect information about CPU cores 0 to 3, enter -c 0-3. To collect information about all CPU cores, enter -c all.

Figure 1 CPU information

If a -- is not displayed in red in the report, the related data is either unavailable or cannot be collected.
If the message is displayed in CPU Table indicating that the current CPU frequency is the frequency expected by the software, the current CPU frequency is obtained from sys/devices/system/cpu/cpu{}/cpufreq/scaling_cur_freq.

**Table 2** Report description
Item	Description
CPU	Displays basic CPU information, including the name, architecture, mode, step, basic frequency, maximum frequency, number of cores, hyper-threading status, number of slots, number of NUMA nodes, NUMA queue list, L1/L2/L3 cache, and number of memory channels.
CPU Table	Displays details about each CPU core, including the CPU ID, physical core ID, logical core ID, slot, NUMA node, frequency, minimum performance percentage, mode, 3-level cache, forcible latency, EPB, and CPU cluster.
JSON Report	The generated report is saved in the Tool_installation_path/output/kspect-cpu-YYYYMMDD-HHMMSS directory and the file name is kspect-cpu-YYYYMMDD-HHMMSS.json.
