//! A helper macro for building scatter-gather task table entries.
|
|
//!
|
|
//! \param ui32TransferCount is the count of items to transfer for this task.
|
|
//! \param ui32ItemSize is the bit size of the items to transfer for this task.
|
|
//! \param ui32SrcIncrement is the bit size increment for source data.
|
|
//! \param pvSrcAddr is the starting address of the data to transfer.
|
|
//! \param ui32DstIncrement is the bit size increment for destination data.
|
|
//! \param pvDstAddr is the starting address of the destination data.
|
|
//! \param ui32ArbSize is the arbitration size to use for the transfer task.
|
|
//! \param ui32Mode is the transfer mode for this task.
|
|
//!
|
|
//! This macro is intended to be used to help populate a table of uDMA tasks
|
|
//! for a scatter-gather transfer. This macro will calculate the values for
|
|
//! the fields of a task structure entry based on the input parameters.
|
|
//!
|
|
//! There are specific requirements for the values of each parameter. No
|
|
//! checking is done so it is up to the caller to ensure that correct values
|
|
//! are used for the parameters.
|
|
//!
|
|
//! The \e ui32TransferCount parameter is the number of items that will be
|
|
//! transferred by this task. It must be in the range 1-1024.
|
|
//!
|
|
//! The \e ui32ItemSize parameter is the bit size of the transfer data. It
|
|
//! must be one of \b UDMA_SIZE_8, \b UDMA_SIZE_16, or \b UDMA_SIZE_32.
|
|
//!
|
|
//! The \e ui32SrcIncrement parameter is the increment size for the source
|
|
//! data. It must be one of \b UDMA_SRC_INC_8, \b UDMA_SRC_INC_16,
|
|
//! \b UDMA_SRC_INC_32, or \b UDMA_SRC_INC_NONE.
|
|
//!
|
|
//! The \e pvSrcAddr parameter is a void pointer to the beginning of the source
|
|
//! data.
|
|
//!
|
|
//! The \e ui32DstIncrement parameter is the increment size for the destination
|
|
//! data. It must be one of \b UDMA_DST_INC_8, \b UDMA_DST_INC_16,
|
|
//! \b UDMA_DST_INC_32, or \b UDMA_DST_INC_NONE.
|
|
//!
|
|
//! The \e pvDstAddr parameter is a void pointer to the beginning of the
|
|
//! location where the data will be transferred.
|
|
//!
|
|
//! The \e ui32ArbSize parameter is the arbitration size for the transfer, and
|
|
//! must be one of \b UDMA_ARB_1, \b UDMA_ARB_2, \b UDMA_ARB_4, and so on
|
|
//! up to \b UDMA_ARB_1024. This is used to select the arbitration size in
|
|
//! powers of 2, from 1 to 1024.
|
|
//!
|
|
//! The \e ui32Mode parameter is the mode to use for this transfer task. It
|
|
//! must be one of \b UDMA_MODE_BASIC, \b UDMA_MODE_AUTO,
|
|
//! \b UDMA_MODE_MEM_SCATTER_GATHER, or \b UDMA_MODE_PER_SCATTER_GATHER. Note
|
|
//! that normally all tasks will be one of the scatter-gather modes while the
|
|
//! last task is a task list will be AUTO or BASIC.
|
|
//!
|
|
//! This macro is intended to be used to initialize individual entries of
|
|
//! a structure of tDMAControlTable type, like this:
|
|
//!
|
|
//! \verbatim
|
|
//! tDMAControlTable MyTaskList[] =
|
|
//! {
|
|
//! uDMATaskStructEntry(Task1Count, UDMA_SIZE_8,
|
|
//! UDMA_SRC_INC_8, MySourceBuf,
|
|
//! UDMA_DST_INC_8, MyDestBuf,
|
|
//! UDMA_ARB_8, UDMA_MODE_MEM_SCATTER_GATHER),
|
|
//! uDMATaskStructEntry(Task2Count, ...),
|
|
//! }
