PsVirtualToPhysical

Converts a virtual address to a physical address.

Syntax

PULSE_STATUS PsVirtualToPhysical(
[in] PPS_ENGINE pEngine,
[in] uint64_t PageTableAddress,
[in] uint16_t Selector,
[in] uint64_t Offset,
[out, optional] uint64_t* pPhysicalAddress
);

Parameters

PPS_ENGINE pEngine

An opaque handle to an engine created by the EngCreateEngine function.

uint64_t PageTableAddress

The target page-table root address. This page-table is used to perform the page walk for the specified address. The currently loaded page-table address is stored in the CR3 register.

uint16_t Selector

The segment selector value used to convert the virtual address into a physical address.

uint64_t Offset

The segment offset value used to convert the virtual address into a physical address.

uint64_t* pPhysicalAddress

Receives the resulting physical address.

Return value

If the function succeeds, the return value is PULSE_STATUS_SUCCESS.

If it fails, it returns one of the PULSE_STATUS values. Possible return codes include, but are not limited to, the following:

PULSE_STATUS_INSUFFICIENT_RESOURCES 0xC0000002	One of the memory allocations failed during initialization.
PULSE_STATUS_TIMEOUT 0xC0000007	Might happen if Transport I/O timed out. No response was received from the debuggee within the request timeout period.
PULSE_STATUS_INVALID_PARAMETER 0xC0000010	Might happen if The pEngine parameter is NULL.
PULSE_STATUS_INVALID_PACKET 0xC0000031	An invalid or unexpected packet was received in response.
PULSE_STATUS_INVALID_TRANSLATION 0xC0000021	Virtual to physical address translation failed. Might happen if the effective address exceeds the segment limit or there is no valid translation to the physical address.
PULSE_STATUS_DEVICE_CONNECTION_LOST 0xC0000308	The connection to the transport was lost. Try restarting the engine or the transport.
