有没有办法判断我的硬件是否支持特定指令?

有没有办法判断我的硬件是否支持特定指令?

微软表示,Windows 2016 服务器,

Minimum:
1.4 GHz 64-bit processor
Compatible with x64 instruction set
Supports NX and DEP
Supports CMPXCHG16b, LAHF/SAHF, and PrefetchW
Supports Second Level Address Translation (EPT or NPT)
1

有没有办法找出

  • HP Workstation xw6200 – Intel E7525 芯片组,或
  • 戴尔 PowerEdge R710 2 x 2.53Ghz E5540

支持这些,而无需手动详尽地搜索每个芯片上的文档。

Per,Ramhound,有一个名为核心信息提供类似cat /proc/cpuinfoLinux 的功能。

你必须搜索一下,但你可以在这里找到信息,

LAHF-SAHF       -       Supports LAHF/SAHF instructions in 64-bit mode
NX              -       Supports no-execute page protection
CX16            *       Supports CMPXCHG16B instruction
X64             *       Supports 64-bit mode
PREFETCHW       -       Supports PREFETCHW instruction

-CPU 缺少该功能意味着它*具有该功能。

现在我看,coreinfo 实际上是微软建议在文档页面上做出决定的,

核心信息是一个可以用来确认您的 CPU 具有哪些功能的工具。+

我的处理器 Intel E7525 的完整结果如下,
