Revision b03c720211ea5ec027ad85f1e147e3d8122429ba authored by Pyun YongHyeon on 14 January 2010, 21:54:20 UTC, committed by Pyun YongHyeon on 14 January 2010, 21:54:20 UTC
Add bus_dma(9) and endianness support to ste(4). o Sorted includes and added missing header files. o Added basic endianness support. In theory ste(4) should work on any architectures. o Remove the use of contigmalloc(9), contigfree(9) and vtophys(9). o Added 8 byte alignment limitation of TX/RX descriptor. o Added 1 byte alignment requirement for TX/RX buffers. o ste(4) controllers does not support DAC. Limit DMA address space to be within 32bit address. o Added spare DMA map to gracefully recover from DMA map failure. o Removed dead code for checking STE_RXSTAT_DMADONE bit. The bit was already checked in each iteration of loop so it can't be true. o Added second argument count to ste_rxeof(). It is used to limit number of iterations done in RX handler. ATM polling is the only consumer. o Removed ste_rxeoc() which was added to address RX stuck issue (cvs rev 1.66). Unlike TX descriptors, ST201 supports chaining descriptors to form a ring for RX descriptors. If RX descriptor chaining is not supported it's possible for controller to stop receiving incoming frames once controller pass the end of RX descriptor which in turn requires driver post new RX descriptors to receive more frames. For TX descriptors which does not support chaning, we exactly do manual chaining in driver by concatenating new descriptors to the end of previous TX chain. Maybe the workaround was borrowed from other drivers that does not support RX descriptor chaining, which is not valid for ST201 controllers. I still have no idea how this address RX stuck issue and I can't reproduce the RX stuck issue on DFE-550TX controller. o Removed hw.ste_rxsyncs sysctl as the workaround was removed. o TX/RX side bus_dmamap_load_mbuf_sg(9) support. o Reimplemented optimized ste_encap(). o Simplified TX logic of ste_start_locked(). o Added comments for TFD/RFD requirements. o Increased number of RX descriptors to 128 from 64. 128 gave much better performance than 64 under high network loads.
