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 --- python/m5/objects/Ethernet.py | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'python/m5/objects') diff --git a/python/m5/objects/Ethernet.py b/python/m5/objects/Ethernet.py index 6113e656f..68b21b404 100644 --- a/python/m5/objects/Ethernet.py +++ b/python/m5/objects/Ethernet.py @@ -105,8 +105,14 @@ class Sinic(EtherDevBase): rx_max_copy = Param.MemorySize('1514B', "rx max copy") tx_max_copy = Param.MemorySize('16kB', "tx max copy") rx_max_intr = Param.UInt32(10, "max rx packets per interrupt") - rx_fifo_threshold = Param.MemorySize('48kB', "rx fifo high threshold") - tx_fifo_threshold = Param.MemorySize('16kB', "tx fifo low threshold") + rx_fifo_threshold = Param.MemorySize('384kB', "rx fifo high threshold") + rx_fifo_low_mark = Param.MemorySize('128kB', "rx fifo low threshold") + tx_fifo_high_mark = Param.MemorySize('384kB', "tx fifo high threshold") + tx_fifo_threshold = Param.MemorySize('128kB', "tx fifo low threshold") + virtual_count = Param.UInt32(1, "Virtualized SINIC") + zero_copy = Param.Bool(False, "Zero copy receive") + delay_copy = Param.Bool(False, "Delayed copy transmit") + virtual_addr = Param.Bool(False, "Virtual addressing") class SinicInt(EtherInt): type = 'SinicInt' -- cgit v1.2.3
