  • 09d8a1e125 Add a very poor implementation of dealing with retries on timing requests. It is especially slow with tracing on since it ends up being O(N^2). But it's probably going to have to change for the real bus anyway, so it should be rewritten then Change recvRetry() to not accept a packet. Sendtiming should be called again (and can respond with false or true) Removed Port Blocked/Unblocked and replaced with sendRetry(). Remove possibility of packet mangling if packet is going to be refused anyway in bridge Ali Saidi 2006-05-30 18:57:42 -04:00

  • c0cf76c837 Create a new CpuEvent class that has a pointer to an execution context in the object and places itself on a global list so so the events can be migrated on cpu switches. Create a new wrapper classe called CpuEventWrapper that works like the old wrapper class but calls the function with the xc parameter Use new CpuEventWrapper class from tick compare events on sparc Ali Saidi 2006-05-29 18:24:27 -04:00
  • dc29a7c8ae split off fullsystem and se iprs into two functions to remove lots of #ifs setup all initialization stuff for UA2005 Setup fullsys build options Start to make fullsystem compile Ali Saidi 2006-05-29 16:53:47 -04:00
  • 4b855592eb Added in the IprAccessOp flag for priveleged and hyperpriveleged instructions. Gabe Black 2006-05-29 00:02:44 -04:00
  • 5cc0306691 Moved the Bit64 constant out of the regfile.hh into isa_traits.cc, which is the only place it was used. Gabe Black 2006-05-28 23:50:23 -04:00
  • 981471c31d Used the Priv and new HPriv instruction formats, which have been tweaked to let some checks be done by the misc reg file. Gabe Black 2006-05-28 23:49:29 -04:00
  • a433cf140e Fixed this to run from the newmem directory to be compatible with how things have been moved around. Gabe Black 2006-05-28 23:48:24 -04:00
  • 82a76d18e1 Remove authors from copyright. Ali Saidi 2006-05-28 23:26:15 -04:00
  • de20b819f1 remove some getPtr() calls by changing having function return values instead of taking a pointer Ali Saidi 2006-05-28 22:21:57 -04:00
  • 5df77b865d Merge zizzer:/bk/newmem into zeep.pool:/z/saidi/work/m5.newmem Ali Saidi 2006-05-26 18:40:08 -04:00
  • e04f60667a Implement PR/HPR/ASR for full system Rip out storage in miscreg file that will never store anything Add storage and defines for Priv and Hyperpriv registers Change defines to match the spec register numbers Change the way misc registers are named to match the spec with offsets to deal with ASR/PR/HPR/FSR. Change contextval to an int since both global registers and windowed registers are indexed by int in UA2005. Use bitfields for things that are rarely used in decoder Instead of decoding ASR/PR/HPR and having a specfic instruction, use a generic instruction instead Ali Saidi 2006-05-26 18:40:00 -04:00

  • 53510f1844 Fixes for TimingSimpleCPU under full system. Now boots Alpha Linux! Steve Reinhardt 2006-05-26 14:33:43 -04:00
  • acb05ebcf6 Reorganize bridge as pair of cooperating ports. Store original source & senderState for timing packets that get a response, so we can properly route the response packet back to the original sender. Steve Reinhardt 2006-05-26 14:29:29 -04:00
  • cdad113afb Add a little more tracing support for Bus/Port stuff. Steve Reinhardt 2006-05-26 14:24:46 -04:00
  • e533fad711 Significant rework of Packet class interface: - new constructor guarantees initialization of most fields - flags track status of non-guaranteed fields (addr, size, src) - accessor functions (getAddr() etc.) check status on access - Command & Result classes are nested in Packet class scope - Command now built from vector of behavior bits - string version of Command for tracing - reinitFromRequest() and makeTimingResponse() encapsulate common manipulations of existing packets Steve Reinhardt 2006-05-26 14:17:33 -04:00

  • 358cf1b117 Rework how instructions are scheduled and executed. The "execute" portion of IEW is really just the last cycle of execution, at which point execute() gets called. Execution begins inside the IQ, when it schedules FUs for specific instructions. As a result, the Execute stage should just pull all completing instructions out of the IQ stage and execute them. Limiting the number of writebacks outstanding must still be done. Kevin Lim 2006-05-23 17:03:43 -04:00
  • c9ad4a15d6 Cleanup checker. Kevin Lim 2006-05-23 16:59:13 -04:00

  • ff3d16ca1f Move kernel stats out of CPU and into XC. Kevin Lim 2006-05-23 16:51:16 -04:00
  • eeeee7c58f Add extra flags to help new CPU handle various instructions. IsIprAccess flag may go away in the future (op class can be used to tell this), and the CPU still needs a specific way to identify/deal with syscalls. Kevin Lim 2006-05-23 14:38:16 -04:00
  • 20051d41d5 Make scons auto-configure stuff per-build-root. Undo changes to allow multiple build roots in a single invocation... this would have been too messy to maintain with the auto-configure stuff, and probably isn't useful anyway. Steve Reinhardt 2006-05-22 22:37:56 -04:00
  • 475a981f6e Get rid of FastCPU model. It doesn't compile, and if we really want this we should start over from scratch and see if we can reuse parts from BaseSimpleCPU (e.g., derive a FastSimpleCPU). Steve Reinhardt 2006-05-22 22:18:08 -04:00
  • 3878895264 Fix to SPARC Nop class for multiple CPU models. Steve Reinhardt 2006-05-22 22:15:22 -04:00
  • 2af0daa59f Make CPU_MODELS default to just the two SimpleCPU variants for now (since those are the only ones that compile). Steve Reinhardt 2006-05-22 22:14:10 -04:00
  • a7c95f702c Clean up libelf handling. Steve Reinhardt 2006-05-22 21:51:59 -04:00
  • 28ea972942 have multiple global levels (as required by UA2005) Ali Saidi 2006-05-22 17:38:00 -04:00
  • 7df1412ccd Undo changes to instruction flags that has caused statistics to change in regressions. This temporarily will break the O3 and Ozone CPU models. Updates to fix them will be coming soon. Kevin Lim 2006-05-22 16:01:25 -04:00
  • c88f0810c0 Forgot to delete the now-obsolete mkbuilddir script. Steve Reinhardt 2006-05-22 14:41:49 -04:00
  • ba2eae5d52 New directory structure: - simulator source now in 'src' subdirectory - imported files from 'ext' repository - support building in arbitrary places, including outside of the source tree. See comment at top of SConstruct file for more details. Regression tests are temporarily disabled; that syetem needs more extensive revisions. Steve Reinhardt 2006-05-22 14:29:33 -04:00

  • fda6ddbffd Rename function to be more expressive. Kevin Lim 2006-05-19 15:45:06 -04:00
  • 5df3e61f16 IEW/IQ code cleanup and reorganization. Dependecy graph code moved into its own class. This requires the changes to the functional units, which is in the next check in. Kevin Lim 2006-05-19 15:44:03 -04:00
  • c4a87f874a Move activity tracking code into its own class. Now the CPU no longer has to keep track of the activity tracking internals; it just calls advance() on the class and uses it to tell if it should deschedule itself. Kevin Lim 2006-05-19 15:37:52 -04:00
  • c7e7d07ec3 Fixes for regression build errors. Kevin Lim 2006-05-19 14:27:46 -04:00

  • 36581a5342 Faults generated at fetch are passed to the backend by creating a dummy nop instruction and giving it the fault. This unifies front end faults and normal instruction faults. Kevin Lim 2006-05-17 14:25:10 -04:00

  • 5da14ec60a Merge zizzer:/bk/newmem into zeep.pool:/z/saidi/work/m5.newmem Ali Saidi 2006-05-16 23:58:37 -04:00
  • a873cd2ca1 add single fs newmem test Ali Saidi 2006-05-16 23:58:31 -04:00
  • 309e1d8193 Split SimpleCPU into two different models, AtomicSimpleCPU and TimingSimpleCPU, which use atomic and timing memory accesses respectively. Common code is factored into the BaseSimpleCPU class. AtomicSimpleCPU includes an option (simulate_stalls) to add delays based on the estimated latency reported by the atomic accesses. Plain old "SimpleCPU" is gone; I have not updated all the config files (just test/test.py). Also fixes to get timing accesses working in new memory model and to get split-phase memory instruction definitions working with new memory model as well. Steve Reinhardt 2006-05-16 17:36:50 -04:00

  • ef6e2eb3c4 Updates for sampler, checker, and general correctness. Kevin Lim 2006-05-16 14:06:35 -04:00
  • c23b23f4e7 Add in checker. Supports dynamically verifying the execution of instructions, as well as limited amount of control path verification. It will verify anything within the program, but anything external (traps, interrupts, XC) it assumes is redirected properly by the CPU. Similarly it assumes the results of store conditionals, uncached loads, and instructions marked as "unverifiable" are correct from the CPU. Kevin Lim 2006-05-16 13:59:29 -04:00

  • 149b724b86 Fixed some problems with signed vs. unsigned numbers which were breaking conditional moves and signed divisions. Also did some minor clean ups. Gabe Black 2006-05-14 23:57:21 -04:00
  • 42313f33ef Made the decoder handle reg_or_imm type arguments with type qualifiers. Gabe Black 2006-05-14 23:56:16 -04:00
  • b91b877e9a Made EM_SPARC32PLUS be recognized as belonging to the SPARC architecture. Programs which have this set will not work because the stack works differently, so this should probably throw an error and quit. Gabe Black 2006-05-14 23:55:07 -04:00
