View the official Windows Driver Kit DDI referenceNo description available.
DXGKARGCB_RESERVEGPUVIRTUALADDRESSRANGE contains the arguments used by the DXGKCB_RESERVEGPUVIRTUALADDRESSRANGE callback function, to allow the kernel-mode display driver to reserve a graphics processing unit (GPU) virtual address range during creation of a process.
hDxgkProcess [in]The process handle that was passed to DxgkDdiCreateProcess.
SizeInBytes [in]The size in bytes of the virtual address range. SizeInBytes must be set to an integral multiple of the address space covered by a single page table entry.
Alignment [in]The number of bytes to align the start address to. Must be a multiple of the address space covered by a single page table entry and a power of 2.
StartVirtualAddress [out]The starting location of the reserved address range.
BaseAddress [in]The base virtual address of the virtual address range in bytes. It must be aligned to the size of the address space, covered by a single page table entry.
AllowUserModeMapping [in]When set, allows the user-mode driver to map allocations to the range.
Flags [in]A single value containing the flags set in the structure.
