如何从 dmidecode 输出中找到 L1、L1d、L1i 缓存？

（注意：dmidecode文件来自不同的服务器，我无法访问，所以我无法运行lscpu命令来查找相同的文件）

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

cat dmi.txt | grep -i core
    Core Count: 2
    Core Enabled: 2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Handle 0x0700, DMI type 7, 19 bytes

        Socket Designation: Not Specified
        Configuration: Enabled, Not Socketed, Level 1  <------------  
        Operational Mode: Write Back
        Location: Internal
        Installed Size: 32 kB  <---------------------------
        Maximum Size: 32 kB
        Supported SRAM Types:
                Unknown
        Installed SRAM Type: Unknown
        Speed: Unknown
        Error Correction Type: None
        System Type: Data
        Associativity: 4-way Set-associative

Handle 0x0701, DMI type 7, 19 bytes

或者我是否需要检查更多信息？

您无法从 dmidecode 获取有关 L1、L1d 和 L1i 缓存的信息。它仅提供总的 L1 L2 和 L3 缓存信息。

lscpu 是一个简洁的命令，可以为您提供缓存信息。

lscpu|grep cache

您还可以在 /sys/devices/system/cpu/ 中获得更多信息
