From 8e9d44477c6d9b48a10ee26e469962fe539ad4ba Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Wed, 26 Apr 2006 17:52:33 -0400 Subject: Major update to sinic to support VSINIC better dev/sinic.cc: - Size the virtualRegs array based on the configured value - Add debugging stuff for uniquely identifying vnic usage - Only count totally unprocessed packets when notifying via RxDone - Add initial virtual address support - Fix some bugs in accessing packets out of order to make sure that busy packets are processed first - Add fifo watermark stuff - Make number of vnics, zero/delay copy and watermarks parameters dev/sinic.hh: add rxUnique and txUnique to uniquely identify tx and rx VNICs Create a separate list of Busy VNICs since more than one might be busy and we want to service those first Add more watermark stuff and new parameters dev/sinicreg.hh: Make the number of virtual nics a read-only parameter add bits for ZeroCopy/DelayCopy rename Virtual to Vaddr so it's not ambiguous Add a flag for TxData/RxData to indicate a virtual address Report rxfifo status in RxDone python/m5/objects/Ethernet.py: add more options for the fifo thresholds add number of vnics as a parameter add copy type as a parameter add virtual addressing as a parameter --HG-- extra : convert_revision : 850e2433b585d65469d4c5d85ad7ca820db10f4a --- dev/sinic.cc | 233 +++++++++++++++++++++++++++++++++++------- dev/sinic.hh | 16 ++- dev/sinicreg.hh | 24 +++-- python/m5/objects/Ethernet.py | 10 +- 4 files changed, 234 insertions(+), 49 deletions(-) diff --git a/dev/sinic.cc b/dev/sinic.cc index 88e365e66..d19ef268f 100644 --- a/dev/sinic.cc +++ b/dev/sinic.cc @@ -85,7 +85,8 @@ Base::Base(Params *p) } Device::Device(Params *p) - : Base(p), plat(p->plat), physmem(p->physmem), + : Base(p), plat(p->plat), physmem(p->physmem), rxUnique(0), txUnique(0), + virtualRegs(p->virtual_count < 1 ? 1 : p->virtual_count), rxFifo(p->rx_fifo_size), txFifo(p->tx_fifo_size), rxKickTick(0), txKickTick(0), txEvent(this), rxDmaEvent(this), txDmaEvent(this), @@ -315,12 +316,9 @@ void Device::prepareIO(int cpu, int index) { int size = virtualRegs.size(); - if (index < size) - return; - - virtualRegs.resize(index + 1); - for (int i = size; i <= index; ++i) - virtualRegs[i].rxPacket = rxFifo.end(); + if (index > size) + panic("Trying to access a vnic that doesn't exist %d > %d\n", + index, size); } void @@ -333,7 +331,10 @@ Device::prepareRead(int cpu, int index) // update rx registers uint64_t rxdone = vnic.RxDone; - rxdone = set_RxDone_Packets(rxdone, rxFifo.packets()); + rxdone = set_RxDone_Packets(rxdone, rxFifo.countPacketsAfter(rxFifoPtr)); + rxdone = set_RxDone_Empty(rxdone, rxFifo.empty()); + rxdone = set_RxDone_High(rxdone, rxFifo.size() > regs.RxFifoMark); + rxdone = set_RxDone_NotHigh(rxdone, rxLow); regs.RxData = vnic.RxData; regs.RxDone = rxdone; regs.RxWait = rxdone; @@ -527,10 +528,32 @@ Device::writeBar0(MemReqPtr &req, Addr daddr, const uint8_t *data) panic("receive machine busy with another request!
