Member Function Documentation

each()

return_t dxd::linked::list< doubly::linked::abstract::event >::each ( exec_t exec )

inlineinherited

Here is the caller graph for this function:

free()

void dxd::buffer< scope_t, 64, 0, false >::free ( )

inlineinherited

initialize() [1/9]

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

inlineinherited

IOKit memory initializer.

initialize() [2/9]

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

inlineinherited

IOKit memory initializer.

initialize() [3/9]

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

inherited

IOKit memory initializer from kernel virtual addresses.

Allows re-initialization.

Creates OS memory descriptor from kernel space data,size and

wires it down and synchronizes it.

Parameters

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

initialize() [4/9]

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() [5/9]

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!

initialize() [6/9]

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

inlineinherited

initialize() [7/9]

os_result dxd::buffer< scope_t, 64, 0, false >::initialize ( size_t size, unsigned int limit = limit_t, unsigned int alignment = alignment_t, bool contigous = contigous_t )

inlineinherited

IOKit buffer initializer.

Allows re-initialization.

Creates a buffer and associated memory descriptor.

Wires down the backing store memory.

Parameters

size	size to be alloced by buffer object
limit	limit physical memory address space
alignment	enforce physical memory alignment
contigous	enforce contiguos physical memory

initialize() [8/9]

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

inherited

IOKit memory initializer from kernel virtual addresses.

Allows re-initialization.

Creates OS memory descriptor from kernel space data,size and

wires it down and synchronizes it.

Parameters

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

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
