一、Linux下查看CPU Cache级数,每级大小
(1) 第一种方法:
dmesg | grep cache
(2) 第二种方法:
[root@gc15 ~]# ls /sys/devices/system/cpu/cpu0/cache/index
index0/ index1/ index2/ index3/
一级cache, Data cache
index0和Index1是一级cache中的data和instruction cache
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index0/level
1
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index0/type
Data
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index0/size
32K
一级cache, Instruction cache
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index1/level
1
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index1/type
Instruction
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index1/size
32K
二级cache,共享的
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index2/level
2
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index3/type
Unified
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index2/size
256K
三级cache,共享的
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index3/level
3
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index3/type
Unified
[root@gc15 ~]# cat /sys/devices/system/cpu/cpu0/cache/index3/size
12288K
