#include <device_memory.hpp>
Public Member Functions | |
void | copyTo (DeviceMemory &other) const |
Performs data copying. If destination size differs it will be reallocated. More... | |
void | create (size_t sizeBytes_arg) |
Allocates internal buffer in GPU memory. If internal buffer was created before the function recreates it with new size. If new and old sizes are equal it does nothing. More... | |
DeviceMemory () | |
Empty constructor. More... | |
DeviceMemory (const DeviceMemory &other_arg) | |
Copy constructor. Just increments reference counter. More... | |
DeviceMemory (size_t sizeBytes_arg) | |
Allocates internal buffer in GPU memory. More... | |
DeviceMemory (void *ptr_arg, size_t sizeBytes_arg) | |
Initializes with user allocated buffer. Reference counting is disabled in this case. More... | |
void | download (void *host_ptr_arg) const |
Downloads data from internal buffer to CPU memory. More... | |
bool | empty () const |
Returns true if unallocated otherwise false. More... | |
template<class U > | |
operator PtrSz< U > () const | |
Conversion to PtrSz for passing to kernel functions. More... | |
DeviceMemory & | operator= (const DeviceMemory &other_arg) |
Assigment operator. Just increments reference counter. More... | |
template<class T > | |
T * | ptr () |
Returns pointer for internal buffer in GPU memory. More... | |
template<class T > | |
const T * | ptr () const |
Returns constant pointer for internal buffer in GPU memory. More... | |
void | release () |
Decrements reference counter and releases internal buffer if needed. More... | |
size_t | sizeBytes () const |
void | swap (DeviceMemory &other_arg) |
Performs swap of data pointed with another device memory. More... | |
void | upload (const void *host_ptr_arg, size_t sizeBytes_arg) |
Uploads data to internal buffer in GPU memory. It calls create() inside to ensure that intenal buffer size is enough. More... | |
~DeviceMemory () | |
Destructor. More... | |
Private Attributes | |
void * | data_ |
Device pointer. More... | |
int * | refcount_ |
Pointer to reference counter in CPU memory. More... | |
size_t | sizeBytes_ |
Allocated size in bytes. More... | |
