DXGKCB_HARDWARECONTENTPROTECTIONTEARDOWN callback function (d3dkmddi.h)

  • Article

DXGKCB_HARDWARECONTENTPROTECTIONTEARDOWN is called when a hardware content protection tear-down event occurs.

Syntax

DXGKCB_HARDWARECONTENTPROTECTIONTEARDOWN DxgkcbHardwarecontentprotectionteardown;

void DxgkcbHardwarecontentprotectionteardown(
  [in] IN_CONST_HANDLE hAdapter,
  [in] UINT Flags
)
{...}

Parameters

[in] hAdapter

A handle to the graphics adapter where the tear-down event is occurring.

[in] Flags

Additional flags defined by the DXGK_HARDWARE_CONTENT_PROTECTION_TEARDOWN_FLAGS enumeration.

Return value

None

Remarks

The kernel-mode display miniport driver should always call DXGKCB_HARDWARECONTENTPROTECTIONTEARDOWN both before and after a hardware content protection tear-down event occurs.

DXGKCB_XXX functions are implemented by Dxgkrnl. To use this callback function, call DxgkCbHardwareContentProtectionTeardown via the DXGKRNL_INTERFACE. The driver can call this callback at either passive level or at dispatch level.
