continuing on for size. Again, you *must* observe the cache line
boundaries when doing this.
int
dma_declare_coherent_memory(struct device *dev, dma_addr_t bus_addr,
dma_addr_t device_addr, size_t size, int
flags)
Declare region of memory to be handed out by dma_alloc_coherent when
it's asked for coherent memory for this device.
bus_addr is the physical address to which the memory is currently
assigned in the bus responding region (this will be used by the
platform to perform the mapping)
device_addr is the physical address the device needs to be programmed
with actually to address this memory (this will be handed out as the
dma_addr_t in dma_alloc_coherent())
size is the size of the area (must be multiples of PAGE_SIZE).
flags can be or'd together and are
DMA_MEMORY_MAP - request that the memory returned from
dma_alloc_coherent() be directly writeable.
DMA_MEMORY_IO - request that the memory returned from
dma_alloc_coherent() be addressable using read/write/memcpy_toio etc.
One or both of these flags must be present
DMA_MEMORY_INCLUDES_CHILDREN - make the declared memory be allocated by
dma_alloc_coherent of any child devices of this one (for memory residing
on a bridge).
DMA_MEMORY_EXCLUSIVE - only allocate memory from the declared regions.
Do not allow dma_alloc_coherent() to fall back to system memory when
it's out of memory in the declared region.
The return value will be either DMA_MEMORY_MAP or DMA_MEMORY_IO and
must correspond to a passed in flag (i.e. no returning DMA_MEMORY_IO
if only DMA_MEMORY_MAP were passed in) for success or zero for
failure.
Note, for DMA_MEMORY_IO returns, all subsequent memory returned by
dma_alloc_coherent() may no longer be accessed directly, but instead
must be accessed using the correct bus functions. If your driver
isn't prepared to handle this contingency, it should not specify
DMA_MEMORY_IO in the input flags.
As a simplification for the platforms, only *one* such region of
memory may be declared per device.
For reasons of efficiency, most platforms choose to track the declared
region only at the granularity of a page. For smaller allocations,
you should use the dma_pool() API.
void
dma_release_declared_memory(struct device *dev)
Remove the memory region previously declared from the system. This
API performs *no* in-use checking for this region and will return
unconditionally having removed all the required structures. It is the
drivers job to ensure that no parts of this memory region are
currently in use.
void *
dma_mark_declared_memory_occupied(struct device *dev,
dma_addr_t device_addr, size_t size)
This is used to occupy specific regions of the declared space
(dma_alloc_coherent() will hand out the first free region it finds).
device_addr is the *device* address of the region requested
size is the size (and should be a page sized multiple).
The return value will be either a pointer to the processor virtual
address of the memory, or an error (via PTR_ERR()) if any part of the
region is occupied.
