Detailed Description

template<dx::scope scope_t = dx::kernel>
class dxd::memory< scope_t >

virtual kernel memory description

WDK: virtual kernel memory description.

The dxd::memory is a kernel memory representation of the kernels virtual memory description. It is an internally used wrapper to generate a virtual kernel memory representation from a platform independent pointer:size description.

Constructor & Destructor Documentation

memory() [1/5]

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

dxd::memory< scope_t >::memory ( )

default

IOKit default constructor.

Use this in conjunction with initialize()

memory() [2/5]

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

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

inline

IOKit class constructor.

Calls initialize() member.

Parameters

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

Here is the call graph for this function:

~memory() [1/2]

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

dxd::memory< scope_t >::~memory ( )

inline

IOKit memory destructor.

Calls free() member.

Here is the call graph for this function:

memory() [3/5]

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

dxd::memory< scope_t >::memory ( )

default

memory() [4/5]

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

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

inline

WDK memory constructor.

Parameters

data	source data pointer
size	source data size

Here is the call graph for this function:

memory() [5/5]

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

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

inline

Parameters

mdl	source MDL

Here is the call graph for this function:

~memory() [2/2]

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

virtual dxd::memory< scope_t >::~memory ( )

inlinevirtual

WDK: memory destructor.

Here is the call graph for this function:

Member Function Documentation

free() [1/2]

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

void dxd::memory< scope_t >::free ( )

inline

IOKit memory free.

Checks the underlaying OS memory descriptor,

synchronizes and unwires it from memory and

releases the memory descriptor.

free() [2/2]

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

void dxd::memory< scope_t >::free

(

)

initialize() [1/7]

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

os_result dxd::memory< scope_t >::initialize ( ::IOMemoryDescriptor * iokit_memory_descriptor )

inline

IOKit memory initializer.

Here is the call graph for this function:

initialize() [2/7]

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

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

inline

IOKit memory initializer.

Here is the call graph for this function:

initialize() [3/7]

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

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

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() [4/7]

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

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

initialize() [5/7]

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

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

inline

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() [6/7]

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

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

inline

Here is the call graph for this function:

initialize() [7/7]

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

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

IOKit memory initializer.

Parameters

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

operator const::IOMemoryDescriptor *()

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

dxd::memory< scope_t >::operator const::IOMemoryDescriptor * ( ) const

inline

IOKit IOMemoryDescriptor* implicit cast.

operator uint64_t()

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

dxd::memory< scope_t >::operator uint64_t ( ) const
