i2o_dma_alloc - Allocate DMA memory : struct device pointer to the PCI device of the I2O controller : i2o_dma struct which should get the DMA buffer : length of the new DMA memory
Allocate a coherent DMA memory and write the pointers into addr.
Returns 0 on success or -ENOMEM on failure.
Definition at line 182 of file memory.c.
i2o_dma_free - Free DMA memory : struct device pointer to the PCI device of the I2O controller : i2o_dma struct which contains the DMA buffer
Free a coherent DMA memory and set virtual address of addr to NULL.
Definition at line 221 of file memory.c.
i2o_dma_map_sg - Map a SG List to controller and fill in I2O message.
This function does all necessary DMA handling and also writes the I2O SGL elements into the I2O message. For details on DMA handling see also dma_map_sg(). The pointer sg_ptr will only be set to the end of the SG list if the allocation was successful.
Returns 0 on failure or 1 on success.
Definition at line 127 of file memory.c.
i2o_dma_map_single - Map pointer to controller and fill in I2O message.
This function does all necessary DMA handling and also writes the I2O SGL elements into the I2O message. For details on DMA handling see also dma_map_single(). The pointer sg_ptr will only be set to the end of the SG list if the allocation was successful.
Returns DMA address which must be checked for failures using dma_mapping_error().
Definition at line 71 of file memory.c.
i2o_dma_realloc - Realloc DMA memory : struct device pointer to the PCI device of the I2O controller : pointer to a i2o_dma struct DMA buffer : new length of memory
If there was something allocated in the addr, free it first. If len > 0 than try to allocate it and write the addresses back to the addr structure. If len == 0 set the virtual address to NULL.
Returns the 0 on success or negative error code on failure.
Definition at line 247 of file memory.c.
i2o_sg_tablesize - Calculate the maximum number of elements in a SGL
Return the maximum number of SG elements in a SG list.
Definition at line 30 of file memory.c.
