View the official Windows Driver Kit DDI referenceNo description available.
pfnFreeGpuVirtualAddressCb releases a range of graphics processing unit (GPU) virtual addresses that was previously reserved or mapped.
The callback is a synchronous operation. The freed virtual address should not be accessed immediately after the call. If there are outstanding pfnMapGpuVirtualAddressCb and pfnUpdateGpuVirtualAddressCb operations, which reference the virtual address, they will be ignored after the virtual address is freed. A new virtual address range can be allocated in place of the freed one immediately after return from the function.
The user mode driver must ensure that no allocation, which is used for current rendering operations, is mapped to the address range.
Note When an allocation is freed through pfnDeallocateCb all outstanding GPU virtual addresses are automatically released.
hDeviceA handle to the display device.
unnamedParam2pData [in]
A pointer to a D3DDDICB_FREEGPUVIRTUALADDRESS structure that describes the operation to perform.
If this callback function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
