Allocate pinned CPU host memory

Macros
#define	magma_free_pinned(ptr)
	Frees CPU pinned memory previously allocated by magma_malloc_pinned().

Functions
static magma_int_t	magma_imalloc_pinned (magma_int_t **ptr_ptr, size_t n)
	Type-safe version of magma_malloc_pinned(), for magma_int_t arrays. Allocates n*sizeof(magma_int_t) bytes.
static magma_int_t	magma_index_malloc_pinned (magma_index_t **ptr_ptr, size_t n)
	Type-safe version of magma_malloc_pinned(), for magma_index_t arrays. Allocates n*sizeof(magma_index_t) bytes.
static magma_int_t	magma_smalloc_pinned (float **ptr_ptr, size_t n)
	Type-safe version of magma_malloc_pinned(), for float arrays. Allocates n*sizeof(float) bytes.
static magma_int_t	magma_dmalloc_pinned (double **ptr_ptr, size_t n)
	Type-safe version of magma_malloc_pinned(), for double arrays. Allocates n*sizeof(double) bytes.
static magma_int_t	magma_cmalloc_pinned (magmaFloatComplex **ptr_ptr, size_t n)
	Type-safe version of magma_malloc_pinned(), for magmaFloatComplex arrays. Allocates n*sizeof(magmaFloatComplex) bytes.
static magma_int_t	magma_zmalloc_pinned (magmaDoubleComplex **ptr_ptr, size_t n)
	Type-safe version of magma_malloc_pinned(), for magmaDoubleComplex arrays. Allocates n*sizeof(magmaDoubleComplex) bytes.
magma_int_t	magma_malloc_pinned (void **ptrPtr, size_t size)
	Allocates memory on the CPU in pinned memory.

imalloc_pinned, smalloc_pinned, etc.

Macro Definition Documentation

magma_free_pinned

#define magma_free_pinned

(

ptr

)

Frees CPU pinned memory previously allocated by magma_malloc_pinned().

Parameters

[in]

ptr

Pointer to free.

Returns

MAGMA_SUCCESS

MAGMA_ERR_INVALID_PTR on failure

Function Documentation

magma_malloc_pinned()

magma_int_t magma_malloc_pinned	(	void **	ptrPtr,
		size_t	size )

Allocates memory on the CPU in pinned memory.

Use magma_free_pinned() to free this memory.

Parameters

[out]	ptrPtr	On output, set to the pointer that was allocated. NULL on failure.
[in]	size	Size in bytes to allocate. If size = 0, allocates some minimal size.

Returns

MAGMA_SUCCESS

MAGMA_ERR_HOST_ALLOC on failure

Type-safe versions avoid the need for a (void**) cast and explicit sizeof.
