Python Linux dmidecode,如何通过Parsing获取HW信息？

Question

我正在使用Fedora 17 64bit,安装了dmidecode和python-dmidecode,在我搜索有关如何使用python-dmidecode的文档时,我还没有找到任何东西.我在浏览源代码时找到了一个例子,但没有别的.有谁熟悉这个模块以及如何在python中访问它？您可以引用我的任何文档都会有所帮助.

我正在尝试获取Fedora 17中的硬件规格:

在使用Management命名空间的C#中,我能够获得以下所有内容: 是否可以通过Python在Linux中获得相同的内容？

BIOS
 - Name

Motherboard
 - Manufacturer
 - Model

CPU
 - Name
 - Architecture
 - NumberOfCores
 - CurrentClockSpeed

Memory

 - Manufacturer
 - MemoryType
 - Speed
 - DeviceLocator
 - Capacity

Answer 1

想出来,通过使用以下我们可以获得我需要的所有数据:

import dmidecode
from pprint import pprint

def getBIOS():
    for v in dmidecode.bios().values():
        if type(v) == dict and v['dmi_type'] == 0:
            BIOSdict["Name"] = str((v['data']['Vendor']))
            BIOSdict["BuildNumber"] = str((v['data']['Version']))
            BIOSdict["SoftwareElementID"] = str((v['data']['BIOS Revision'])

)

我们迭代dmidecode.bios().values()以找到每个数据字段.我们可以通过参考下表来查看要使用的功能.哪个也位于此链接.

然后我们检查它的类型'v'以确保它的类型dictionary (这就是我在我的情况下使用的)并且我们检查'dmi_type'是我们正在搜索的内容的正确代码.

例如:

   Type   Information
       ----------------------------------------
          0   BIOS
          1   System
          2   Base Board
          3   Chassis
          4   Processor
          5   Memory Controller
          6   Memory Module
          7   Cache
          8   Port Connector
          9   System Slots
         10   On Board Devices
         11   OEM Strings
         12   System Configuration Options
         13   BIOS Language
         14   Group Associations
         15   System Event Log
         16   Physical Memory Array
         17   Memory Device
         18   32-bit Memory Error
         19   Memory Array Mapped Address
         20   Memory Device Mapped Address
         21   Built-in Pointing Device
         22   Portable Battery
         23   System Reset
         24   Hardware Security
         25   System Power Controls
         26   Voltage Probe
         27   Cooling Device
         28   Temperature Probe
         29   Electrical Current Probe
         30   Out-of-band Remote Access
         31   Boot Integrity Services
         32   System Boot
         33   64-bit Memory Error
         34   Management Device
         35   Management Device Component
         36   Management Device Threshold Data
         37   Memory Channel
         38   IPMI Device
         39   Power Supply


       Keyword     Types
       ------------------------------
       bios        0, 13
       system      1, 12, 15, 23, 32
       baseboard   2, 10
       chassis     3
       processor   4
       memory      5, 6, 16, 17
       cache       7
       connector   8
       slot        9

如果我们想要获取BIOS Info,我们会引用v['dmi_type'] == 0它将返回一个字典.然后我们可以创建自己的dict(在我的例子中BIOSdict = [])并添加键和值,如下所示:

BIOSdict["Name"] = str((v['data']['Vendor']))
