debug_dma_free_coherent

Name:debug_dma_free_coherent

Proto:void debug_dma_free_coherent(struct device *dev, size_t size, void *virt, dma_addr_t addr)

Type:void

Parameter:

Type	Parameter	Name
struct device *	dev
size_t	size
void *	virt
dma_addr_t	addr

struct dma_debug_entry ref = {type = dma_debug_coherent, dev = dev, offset = offset_in_page(virt), dev_addr = addr, size = size, direction = DMA_BIDIRECTIONAL, }

If Not Determine if an address is within the vmalloc range* On nommu, vmalloc/vfree wrap through kmalloc/kfree directly, so there* is no special casing required. && Not virt_addr_valid(virt) Then Return

If Determine if an address is within the vmalloc range* On nommu, vmalloc/vfree wrap through kmalloc/kfree directly, so there* is no special casing required. Then pfn = vmalloc_to_pfn(virt)

1483

Else pfn = page_to_pfn(virt_to_page(kaddr) returns a valid pointer if and only if* virt_addr_valid(kaddr) returns true.(virt))

1486

If Value for the false possibility is greater at compile time(dma_debug_disabled()) Then Return
