- Add IXP4xx NPE ethernet MAC support - Add support for Intel IXDPG425 board - Add support for Prodrive PDNB3 board - Add IRQ support Patch by Stefan Roese, 23 May 2006 [This patch does not include cpu/ixp/npe/IxNpeMicrocode.c which still sufferes from licensing issues. Blame Intel.]

|
|
*
|
|
* @brief The public API for the IXP400 HssAccess component
|
|
*
|
|
* IxHssAcc is the access layer to the HSS packetised and channelised
|
|
* services
|
|
*
|
|
* <b> Design Notes </b><br>
|
|
* <UL>
|
|
* <LI>When a packet-pipe is configured for 56Kbps RAW mode, byte alignment of
|
|
* the transmitted data is not preserved. All raw data that is transmitted
|
|
* will be received in proper order by the receiver, but the first bit of
|
|
* the packet may be seen at any offset within a byte; all subsequent bytes
|
|
* will have the same offset for the duration of the packet. The same offset
|
|
* also applies to all subsequent packets received on the packet-pipe too.
|
|
* (Similar results will occur for data received from remote end.) While
|
|
* this behavior will also occur for 56Kbps HDLC mode, the HDLC
|
|
* encoding/decoding will preserve the original byte alignment at the
|
|
* receiver end.
|
|
* </UL>
|
|
*
|
|
* <b> 56Kbps Packetised Service Bandwidth Limitation </b><br>
|
|
* <UL>
|
|
* <LI>IxHssAcc supports 56Kbps packetised service at a maximum aggregate rate
|
|
* for all HSS ports/HDLC channels of 12.288Mbps[1] in each direction, i.e.
|
|
* it supports 56Kbps packetised service on up to 8 T1 trunks. It does
|
|
* not support 56Kbps packetised service on 8 E1 trunks (i.e. 4 trunks per
|
|
* HSS port) unless those trunks are running 'fractional E1' with maximum
|
|
* aggregate rate of 12.288 Mbps in each direction.<br>
|
|
* [1] 12.288Mbps = 1.536Mbp * 8 T1

|
|
* @param *rxCircular UINT8 [in] - A pointer to memory allocated by the

* client to be filled by data received. The buffer at this address is part

* of a pool of buffers to be accessed in a circular fashion. This address

* will be written to by the NPE. Therefore, it needs to be a physical address.
|
|
* @param numRxBytesPerTS unsigned [in] - The number of bytes allocated per
|
|
* timeslot within the receive memory. This figure will depend on the
|
|
* latency of the system. It needs to be deep enough for data to be read by
|
|
* the client before the NPE re-writes over that memory e.g. if the client
|
|
* samples at a rate of 40bytes per timeslot, numRxBytesPerTS may need to

|
|
* The txPtrs will point to data to be transmitted by the NPE. Therefore,
|
|
* they must point to physical addresses.
|
|
* @param numTxPtrLists unsigned [in] - The number of pointer lists in
|
|
* txPtrList. This figure is dependent on jitter.

* data. If this is not NULL, an ISR will call this function. If this
|

* to detect when the tx and rx of channelised data is to occur. The client
