class FakeCpuidIo
Defined at line 64 of file ../../zircon/kernel/lib/arch/testing/include/lib/arch/testing/x86/fake-cpuid.h
FakeCpuidIo is a fake analogue to arch::BootCpuidIo, which may be provided
in its place for tests - in the kernel and on host - for logic templated
on any type the interface contract of the latter. A "CPUID I/O provider",
FakeCpuidIo's methods are expected to be instantiated by "CPUID value
types", defined in
<lib
/arch/x86/cpuid.h>.
Using `Populate`, test authors can provide fake data for specific
(sub)leaves.
FakeCpuidIo is immovable and non-copyable; it is expected to be passed
around by const reference.
Public Methods

void FakeCpuidIo ()Defined at line 66 of file ../../zircon/kernel/lib/arch/testing/include/lib/arch/testing/x86/fake-cpuid.h
template <typename CpuidValue>const CpuidIo * Get ()Returns the cached CpuidIo object corresponding to the particular CPUID
register type.

FakeCpuidIo & Populate (uint32_t leaf, uint32_t subleaf, uint32_t eax, uint32_t ebx, uint32_t ecx, uint32_t edx)Provides fake data for a given leaf. Subsequent calls can overwrite
previously populated data.
