finding L2 cache size in Linux

Question

I wanted to know how to find L2 cache size in Linux...

for L1 cache size, I am doing the following

pico /proc/cpuinfo

what about L2 cache size?

Answer 1

EDIT 3: Heh, sorry, just do sudo dmidecode -t cache and it will show you your CPU's cache information. To tell what section you are looking at (L1 or L2), look at the Configuration: line. You want Configuration: Enabled, Not Socketed, Level 2.

Answer 2

cat /sys/devices/system/cpu/cpu0/cache/index2/size

or check dmidecode

or use lshw

Answer 3

dmesg | grep cache will show your L1 and L2 related information.
