_DXGK_QUERYPAGETABLELEVELDESCIN structure

Description

The DXGK_QUERYPAGETABLELEVELDESCIN structure is used to request page level descriptors from the Dxgkrnl Interface.

Members

LevelIndex

A zero-based physical adapter index (engine ordinal) for which the data is queried.

PhysicalAdapterIndex

A zero-based page table level index for the information requested.

Remarks

To get page table level descriptors Dxgkrnl calls DxgkDdiQueryAdapterInfo with the following parameters:

DXGKARG_QUERYADAPTERINFO::Type = DXGKQAITYPE_PAGETABLELEVELDESC;
DXGKARG_QUERYADAPTERINFO::pInputData = DXGK_QUERYPAGETABLELEVELDESCIN
DXGKARG_QUERYADAPTERINFO::InputDataSize = sizeof(QUERYPAGETABLELEVELDESCIN)
DXGKARG_QUERYADAPTERINFO::pOutputData = pointer to DXGK_PAGE_TABLE_LEVEL_DESC
DXGKARG_QUERYADAPTERINFO::OutputDataSize = sizeof(DXGK_PAGE_TABLE_LEVEL_DESC);
