2004-10-01fix some bugs in the headers and fix checksumming.Nathan Binkert
base/inet.cc: we can't use a uint16_t for the intermediate checksum values since there may be some bits that carry. the length that is added in the pseudo header is the length of the tcp portion only. base/inet.hh: silly me, the ip_hlen field is in terms of 4-byte words. when caclulating checksum, we're dealing with network byte order, so don't bother doing any byteswapping. --HG-- extra : convert_revision : 993e3413e9febea0ba2fb6ba8bf04c053cca15ed

2004-09-21a bit more cleaning of the network header wrappers.Nathan Binkert
base/inet.hh: add functions to the various headers to grab the most common encapsulated protocols. This could easily get out of hand, but we're just worrying about tcp, udp, and ip for now. add common functions size(), bytes(), and payload() to all wrappers. size() gets the header size bytes() returns a uint8_t * to the beginning of the header payload() returns a uint8_t * to the beginning of the payload. dev/etherpkt.cc: dev/etherpkt.hh: don't cache pointers to headers. It's probably not worth the hassle. --HG-- extra : convert_revision : ba9df85ac019b8a48233042dde79fb9da9546410

2004-09-20Clean up network header stuff and make it more generic. UseNathan Binkert
libdnet when we can instead of our own home grown stuff. SConscript: separate the crc code into its own file base/inet.cc: move the crc stuff to crc.cc add generic code for calculating ip/tcp/udp checksums base/inet.hh: - move crc stuff to crc.hh - #include all of the libdnet stuff. (this makes base/inet.hh the only file you need to include if you want to use this kind of stuff.) - Wrap some of the libdnet structs to get easier access to structure members. These wrappers will automatically deal with masking/shifting/ byte-swapping. base/refcnt.hh: If one derives from RefCountingPtr, they should have access to the internal data pointer. build/SConstruct: make #include of dnet stuff work dev/etherlink.cc: dev/ethertap.cc: dev/ethertap.hh: EtherPacket -> PacketData dev/etherpkt.cc: EtherPacket -> PacketData add a function for populating extra info about a packet. Basically just gives pointers to ethernet/ip/tcp/udp headers if they exist. dev/etherpkt.hh: EtherPacket -> PacketData remove most of the packet header stuff from teh PacketData class and just add a few generic functions for grabbing various headers that may exist in the packet. The old functionality is contained in the headers. dev/ns_gige.cc: - IP -> Ip, UDP -> Udp, TCP ->Tcp when used in variable names - get rid of our own byte swapping functions. - whack checksum code and use libdnet version. - Get pointers to the various packet headers and grab info from those headers. (The byte swapping in the headers now.) - Add stats for Udp Checksums dev/ns_gige.hh: use libdnet for checksum code. IP -> Ip, TCP -> Tcp in variable names add stats for UDP checksums --HG-- extra : convert_revision : 96c4160e1967b7c0090acd456df4a76e1f3aab53

2004-08-20Fixup interrupting of the ethernet device.Nathan Binkert
dev/ns_gige.cc: clean up the interrupt handling code so that it is simpler and less prone to bugs. I hope I removed the bug where the: assert(intrTick >= curTick || intrTick == 0); would get triggered. I'm pretty sure that was due to intrTick not being cleared when the interrupt was cleared. This code probably still needs to be looked at more closely to make sure interrupts are not missed. --HG-- extra : convert_revision : 61e2eb043540f2534a80c9b633006a71e7d6e282

2004-08-20- Clean up and factor out all of the binning code into aNathan Binkert
single place so it's easier to work with. - Add support for binning kernel/user/idle time separately from lisa's binning stuff, but make the two compatible. - KernelStats used to directly implement the pImpl idiom, but it makes more sense to just remove the level of indirection and make the exec context have a pointer to the stats. - Factor common code out of LinuxSystem and Tru64System and put it into the System base class. While doing that, make all constructors take a pointer to a parameter struct instead of naming the parameters individually to make it much easier to add parameters to these classes. SConscript: Move the function tracking and binning stuff around. arch/alpha/ev5.cc: kernelStats is now a pointer arch/alpha/pseudo_inst.cc: kernelStats is now a pointer the parameters to the system have been moved into their own struct base/trace.hh: provide a little functor class for wrapping a string that can allow you to define name() in any scope very simply for use with DPRINTF cpu/base_cpu.cc: New order of arguments for consistency. cpu/exec_context.cc: kernelStats no longer has the level of indirection in it, execContext has the indirection now. so, kernelStats is a pointer. We also need a pointer to the kernelBinning stuff from the system and we need to figure out if we want to do binning or not. Move a whole bunch of code into kern_binning.cc so it's all in the same place. cpu/exec_context.hh: We want pointers to the kernel binning/stats stuff and we'll have the exec_context and system have the level of indirection instead of having the extra layer in the kernel stats class. cpu/simple_cpu/simple_cpu.cc: call through the exec context to do the special binning stuff. kern/kernel_stats.cc: kern/kernel_stats.hh: Re-organize the stats stuff and remove the level of indirection (that was there to simplify building) and move the binning stuff into its own class/file. kern/linux/linux_system.cc: kern/linux/linux_system.hh: kern/tru64/tru64_system.cc: kern/tru64/tru64_system.hh: sim/system.cc: sim/system.hh: move lots of common system code into the base system class so that it can be shared between linux, tru64, and whatever else we decide to support in the future. Make the constructor take a pointer to a parameter struct so that it is easier to pass parameters to the parent. kern/system_events.cc: move the majority of the binning code into the Kernel::Binning class in the kern_binning file kern/system_events.hh: FnEvents only need to know the bin create the Idle start event to find the PCBB of the idle process when it starts. kern/tru64/tru64_events.cc: memCtrl -> memctrl sim/process.cc: sim/process.hh: re-order args for consistency --HG-- extra : convert_revision : 86cb39738c41fcd680f2aad125c9dde000227b2b
