Supporting OpenGL Enhancements

This section applies only to Windows 7 and later, Windows Server 2008 R2 and later.

You can implement your OpenGL installable client driver (ICD) to use the following OpenGL enhancements that ship with Windows 7:

You can enhance the synchronization capabilities of your OpenGL ICD by using the following second-generation OpenGL synchronization functions:

• D3DKMTCreateSynchronizationObject2

• D3DKMTOpenSynchronizationObject

• D3DKMTWaitForSynchronizationObject2

• D3DKMTSignalSynchronizationObject2

You can use the following OpenGL mutex functions to control access to resources:

• D3DKMTCreateKeyedMutex

• D3DKMTOpenKeyedMutex

• D3DKMTDestroyKeyedMutex

• D3DKMTAcquireKeyedMutex

• D3DKMTReleaseKeyedMutex

You can use the following OpenGL functions to manage access to a shared resource:

• D3DKMTConfigureSharedResource

• D3DKMTCheckSharedResourceAccess

You can use the following OpenGL functions to monitor the history of present operations:

• D3DKMTPresent with D3DKMT_PRESENTHISTORYTOKEN structures populated in the PresentHistoryToken member of the D3DKMT_PRESENT structure

• D3DKMTGetPresentHistory

You can use the following OpenGL miscellaneous enhancements:

• D3DKMTCheckVidPnExclusiveOwnership

• D3DKMTGetOverlayState

• D3DKMTSetDisplayMode with the D3DKMT_SETDISPLAYMODE_FLAGS structure populated in the Flags member of the D3DKMT_SETDISPLAYMODE structure

• D3DKMTPollDisplayChildren with new flags set in the D3DKMT_POLLDISPLAYCHILDREN structure

This section applies only to Windows 8 and later, and Windows Server 2012 and later.

You can implement your OpenGL installable client driver (ICD) to use the following OpenGL enhancements that ship with Windows 8:

You can use these OpenGL mutex functions and associated structures to control access to resources while specifying private data to associate with a keyed mutex:

• D3DKMTAcquireKeyedMutex2
• D3DKMTCreateKeyedMutex2
• D3DKMT_ACQUIREKEYEDMUTEX2
• D3DKMT_CREATEKEYEDMUTEX2

You can use these functions and their associated structures to access objects and their handles:

• D3DKMTGetSharedResourceAdapterLuid
• D3DKMTOpenAdapterFromLuid
• D3DKMTOpenNtHandleFromName
• D3DKMTOpenResourceFromNtHandle
• D3DKMTOpenSyncObjectFromNtHandle
• D3DKMT_GETSHAREDRESOURCEADAPTERLUID
• D3DKMT_OPENADAPTERFROMLUID
• D3DKMT_OPENNTHANDLEFROMNAME
• D3DKMT_OPENRESOURCEFROMNTHANDLE
• D3DKMT_OPENSYNCOBJECTFROMNTHANDLE
