Fully qualified name: cupva::GetDriverVersion

const uint32_t cupva::GetDriverVersion()#

Get the version of the PVA driver.

A PVA application and the cuPVA runtime may be deployed on multiple different platform versions. Each BSP version is packaged with a PVA driver, which is versioned based on its compatibility with cuPVA runtime versions. The driver version is represented as an integer defined as (VERSION_MAJOR * 1000 + VERSION_MINOR). If the driver version is greater than or equal to the runtime version while remaining within the same major release, this means that all features of the runtime are fully supported. If the driver version is less than the runtime version, then some APIs may not be available. Refer to individual API documentation for further information.

For example, if the cuPVA runtime version is 2.5, and CupvaGetDriverVersion returns 2005 or 2006, it is guaranteed that the platform fully supports the cuPVA runtime version. If the cuPVA runtime version is 2.6, and CupvaGetDriverVersion returns 2005, some features of the runtime may not be available on that platform.
