How to view device information under linux

View pci device

lspci -v

View cpu information? Answer:

more /proc/cpuinfo

In the cpu information, siblings is the number of logical processors, and cpu cores is the number of cores. When siblings are twice as large as cpu cores, it means that hyper-threading has been turned on; when siblings and cpu cores are consistent, it means that the system Hyper-threading is not supported or hyper-threading is not enabled.

Check the number of cpu

cat /pro/cpuinfo | grep "physical id" | sort | uniq | wc -l

Check the number of cpu cores

cat /proc/cpuinfo | grep "cpu cores"

Check the memory information

more /proc/meminfo
