Detailed Description

struct ppc440spe_adma_desc_slot - PPC440SPE-ADMA software descriptor : hardware address of the hardware descriptor chain : first operation in a transaction : pointer to the next descriptor in chain : support for the async_tx api : node on the iop_adma_chan.all_slots list : node on the op_adma_chan.chain list : list of slots that make up a multi-descriptor transaction for example transfer lengths larger than the supported hw max : transaction bytecount : virtual address of the hardware descriptor chain : currently chained or not : pool index : total slots used in an transaction (group of operations) : number of sources set in this descriptor : number of destinations set in the descriptor : number of slots per operation : number of slot per P/Q operation see comment for ppc440spe_prep_dma_pqxor function : desc state/type : 1 if a corresponding rxor address uses reversed address order : result of zero sum : result crc calculation
