D3DDDI_DRIVERESCAPETYPE enumeration

Description

D3DDDI_DRIVERESCAPETYPE defines the known driver escape types (D3DDDI_ESCAPEFLAGS::DriverKnownEscape).

Constants

`D3DDDI_DRIVERESCAPETYPE_TRANSLATEALLOCATIONHANDLE:0`

Driver escape type to translate allocation handle; used to translate the guest allocation to the corresponding host handle. For more information, see GPU paravirtualization.

`D3DDDI_DRIVERESCAPETYPE_TRANSLATERESOURCEHANDLE:1`

Driver escape type to translate resource handle; used to translate the resource handle to the corresponding host handle. For more information, see GPU paravirtualization.

`D3DDDI_DRIVERESCAPETYPE_CPUEVENTUSAGE:2`

Driver escape type for CPU event usage; used to notify the kernel-mode driver (KMD) about the intended use of a KMD CPU event object. Available starting in Windows 11 (WDDM 3.0). See Signaling a CPU event from KMD for more information.

`D3DDDI_DRIVERESCAPETYPE_BUILDTESTCOMMANDBUFFER:3`

Driver escape type for building a test command buffer; used to build a test command buffer for kernel-mode testing. Available starting in Windows 11, version 24H2 (WDDM 3.2). See Kernel-mode testing for more information.

`D3DDDI_DRIVERESCAPETYPE_MAX`

The maximum value for this enumeration.
