class FakeMsrIo

Defined at line 25 of file ../../zircon/kernel/lib/arch/testing/include/lib/arch/testing/x86/fake-msr.h

FakeMsrIo is a fake analogue to hwreg::X86MsrIo, which may be provided in

its place in tests - in the kernel and on host.

FakeMsrIo is immovable and non-copyable; it is expected to be passed

around by reference.

FakeMsrIo & Populate (X86Msr msr, uint64_t initial_value)

Populate must be called with a particular MSR by a test author before that

same MSR can be used with Read() and Write(). A call will not result in

any side-effects.

uint64_t Peek (X86Msr msr)

Reads the stored MSR value without side-effects. The MSR must have been

`Populate`d before this can be called on it.

void FakeMsrIo ()

Gives a FakeMsrIo with no side-effects, which is little more than a

glorified map of MSR address to value.

void FakeMsrIo (IoCallback on_write, IoCallback on_read)

Constructs a FakeMsrIo with particular on-write and on-read `IoCallback`s.

void FakeMsrIo (IoCallback on_write, IoCallback on_read)

void Write (IntType value, uint32_t msr)

Implements an I/O provider's `Write()` method. An MSR must have been

`Populate`d before this can be called on it.

IntType Read (uint32_t msr)

Implements an I/O provider's `Read()` method. An MSR must have been

`Populate`d before this can be called on it.
