Detailed Description

template<typename stream_t>
class dxd::wavert::miniport< stream_t >

wavert::miniport

stream_t::backend is what its streams start()/stop() against - handed through from the adapter device.

Constructor & Destructor Documentation

miniport()

template<typename stream_t>

dxd::wavert::miniport< stream_t >::miniport ( const wchar_t * portname, const ::DEVICE_OBJECT * wdm_bus, const ::DEVICE_OBJECT * wdm_pdo, const dx::log & log, typename stream_t::backend & backend, const typename stream_t::stream_desc & stream_desc, unsigned int idx, dx::stream::clock::bitmap bitmap )

template<typename stream_t>

dxd::wavert::miniport< stream_t >::~miniport ( )

inline

PortCls tears the subdevices down ahead of the device's own remove handling: the backend's endpoint slot must not reach a gone miniport.

Member Function Documentation

format_change()

template<typename stream_t>

void dxd::wavert::miniport< stream_t >::format_change ( uint32_t samplerate = {} )

inline

the OS pin's ranges narrow to the given rate, widen to the bitmap without one

The port copied the pin descriptor at Init and reads the ranges themselves live, so every rate range is rewritten in place. The endpoint builder re-derives the endpoint's format from them; the backend calls this whenever its clock domain binds or frees the rate.
