struct CpuidIo
Defined at line 30 of file ../../zircon/kernel/lib/arch/include/lib/arch/x86/cpuid.h
An hwreg-compatible interface for reading CPUID values, where the
"addresses" correspond to the EAX, EBX, ECX, and EDX registers. The values
are expected to be programmatically filled before use, e.g., using
the compiler-supplied
<cpuid
.h> (not included here, since it is x86-only):
```
cpuid_count(leaf, subleaf, values_[CpuidIo::kEax], values_[CpuidIo::kEbx],
values_[CpuidIo::kEcx], values_[CpuidIo::kEdx]);
```

template <typename T>T Read (uint32_t reg)The API needs this to be a template even though only one type is valid.
In the general case, this is usually a template that admits multiple
possible integer types. So calls to it from template-generic code use
`io.template Read
<uint32
_t>(offset)` and the like, which is invalid if
this is not a template function.
