IOKit memory initializer.

Here is the call graph for this function:

template<dx::scope scope_t = dx::kernel>

os_result dxd::memory< scope_t >::initialize ( ::IOMemoryDescriptor * iokit_memory_descriptor, size_t offset, size_t size )

IOKit memory initializer.

Here is the call graph for this function:

initialize() [3/8]

template<dx::scope scope_t = dx::kernel>

os_result dxd::memory< scope_t >::initialize ( const void * data, size_t size )

inherited

IOKit memory initializer.

Parameters

data	virtual base address of range to create memory descriptor from
size	size of range to create memory descriptor from

initialize() [4/8]

template<dx::scope scope_t = dx::kernel>

os_result dxd::memory< scope_t >::initialize ( const::MDL * mdl )

inlineinherited

in contrast to an IOKit MemoryDescriptor MDLs do not support reference counting. take care when creating a dxd::memory from a dxd::buffer: although the dxd::memory holds an MDL to the buffer the buffer itself is not retained after the dxd::buffer is released!

Here is the call graph for this function:

initialize() [5/8]

template<dx::scope scope_t = dx::kernel>

os_result dxd::memory< scope_t >::initialize ( const::MDL * mdl, size_t offset, size_t size )

Allows re-initialization.

Creates a buffer and associated memory descriptor.

Wires down the backing store memory.

Parameters
