  • 06d25dcd26 X86: Automatically make the IO APIC in an N CPU system have id N+1. Gabe Black 2009-04-19 02:39:19 -07:00
  • d10195b1a4 CPU: If the simple CPU is already idle, just return from suspendContext, don't assert. Gabe Black 2009-04-19 02:23:29 -07:00
  • 05b5861419 X86: Condense the startupCPU code. Gabe Black 2009-04-19 02:20:57 -07:00
  • f668340f2c X86: Set the local APIC ID to something meaningful. Gabe Black 2009-04-19 02:16:49 -07:00
  • 79a3a6aecb X86: Don't pretend to be an AMD CPU any more. We're not good enough at it. Gabe Black 2009-04-19 02:06:51 -07:00
  • a25aa00522 o3-mips-regress: add hello word regression. Korey Sewell 2009-04-18 10:42:29 -04:00
  • d8a34a9745 mips-tlb-fix: check for alignment faults.\nMIPS was never updated to use TLBS correcty in SE mode. The error was forwarding translations directly to pageTable. The TLB should check for alignment faults at bare minimum here but in the long run we should be using TLBs in SE mode for MIPS. Korey Sewell 2009-04-18 10:42:29 -04:00
  • e501e1af54 mips-syscall: mark with correct flag. \nMIPS was using wrong serialization flag on syscall instructions allowing O3 to handle SE mode syscalls incorrectly and speculate on instructions after a syscall Korey Sewell 2009-04-18 10:42:29 -04:00
  • 5c1742b822 o3-delay-slot-bpred: fix decode stage handling of uncdtl. branches.\n decode stage was not setting the predicted PC correctly or passing that information back to fetch correctly Korey Sewell 2009-04-18 10:42:29 -04:00
  • cc9e834e93 mips-shadowsets: fix calcuations. \n Remove Shadowsets from Int & Arch. Reg Calculations Korey Sewell 2009-04-18 10:42:28 -04:00
  • 14808ecac9 o3, inorder: fix FS bug due to initializing ThreadState to Halted. For some reason o3 FS init() only called initCPU if the thread state was Suspended, which was no longer the case. There's no apparent reason to check, so I whacked the test completely rather than changing the check to Halted. The inorder init() was also updated to be symmetric, though the previous code was just a fancy no-op. Steve Reinhardt 2009-04-17 16:54:58 -07:00
  • b146131d18 o3: handle fetch with no active threads correctly. This situation can arise now on the first fetch cycle after the last active thread is halted. It seems easy enough to deal with when it happens rather than trying to avoid it. Steve Reinhardt 2009-04-15 23:12:00 -07:00
  • bb974d5a47 o3: fix {read,set}ArchFloatReg* functions. Register indices were not being calculated properly. Steve Reinhardt 2009-04-15 23:10:43 -07:00
  • 7617dcf736 ThreadState: initialize status to Halted in constructor. This provides a common initial status for all threads independent of CPU model (unlike the prior situation where CPUs initialized threads to inconsistent states). This mostly matters for SE mode; in FS mode, ISA-specific startupCPU() methods generally handle boot-time initialization of thread contexts (since the right thing to do is ISA-dependent). Steve Reinhardt 2009-04-15 13:18:24 -07:00
  • 48d4ca522a Update stats after elimination of Unallocated state. Somehow ending threads with halt() instead of deallocate() reduces the squash count on o3 by 1 (and a few other similarly trivial changes). Steve Reinhardt 2009-04-15 13:13:58 -07:00
  • 8882dc1283 Get rid of the Unallocated thread context state. Basically merge it in with Halted. Also had to get rid of a few other functions that called ThreadContext::deallocate(), including: - InOrderCPU's setThreadRescheduleCondition. - ThreadContext::exit(). This function was there to avoid terminating simulation when one thread out of a multi-thread workload exits, but we need to find a better (non-cpu-centric) way. Steve Reinhardt 2009-04-15 13:13:47 -07:00
  • 9b66e82897 configs: Allow M5_CPU2000 env var to set CPU2K binary path. It would be nice to have a more comprehensive mechanism but this is a big improvement over manually editing the script. Steve Reinhardt 2009-04-15 12:52:31 -07:00
  • 5c79191603 X86: Fix minor bug in the page table walker from TLB shuffling. Gabe Black 2009-04-13 04:14:15 -07:00

  • 4eea8acaf2 stats: fix compiler error Nathan Binkert 2009-03-16 15:16:58 -07:00
  • 15f0e44060 Very minor regression stats updates due top previous changeset. Setting dirty bit on swaps added a handful of writebacks in a few of the longer-running SPARC_SE benchmarks. Steve Reinhardt 2009-03-16 11:01:23 -04:00
  • 758bfe4eb5 cache: set dirty bit on swaps (oops!) Steve Reinhardt 2009-03-11 23:05:26 -07:00

  • a94c68228a prefetch: don't panic on requests w/o contextID (e.g., writebacks). Steve Reinhardt 2009-03-10 17:37:15 -07:00
  • ac64586a99 build: fix compiler warnings in g++ 3.4 Nathan Binkert 2009-03-07 21:34:50 -08:00
  • 4c902714f7 Minor tweak to regression exit status message. Steve Reinhardt 2009-03-07 17:24:13 -08:00
  • 4f1855484c Fix up regression execution to better handle tests that end abnormally. E.g., mark aborts due to assertion failures as failed tests, but those that get killed by the user as needing to be rerun, etc. Steve Reinhardt 2009-03-07 16:58:51 -08:00
  • 5cf0605766 tests: update tests because of changes in stat names and in the stats package Nathan Binkert 2009-03-07 14:30:55 -08:00

  • fcaf1b74b0 stats: cleanup text output stuff and fix mysql output Nathan Binkert 2009-03-07 14:30:53 -08:00

  • 66a85b54e2 build: fix errors for compilers other than g++ 4.3 Nathan Binkert 2009-03-07 14:30:52 -08:00
  • 6f787e3d36 stats: create an enable phase, and a prepare phase. Enable more or less takes the place of check, but also allows stats to do some other configuration. Prepare moves all of the code that readies a stat for dumping into a separate function in preparation for supporting serialization of certain pieces of statistics data. While we're at it, clean up the visitor code and some of the python code. Nathan Binkert 2009-03-05 19:09:53 -08:00
  • 9f45fbaaa6 stats: clean up how templates are used on the data side. This basically works by taking advantage of the curiously recurring template pattern in an intelligent way so as to reduce the number of lines of code and hopefully make things a little bit clearer. Nathan Binkert 2009-03-05 19:09:53 -08:00

  • c7e82f965f stats: remove the template wart left over from the ancient binning stuff Nathan Binkert 2009-03-05 19:09:53 -08:00
  • 244c2a517a stats: stick the distribution's fancy parameter into the parameters structure. Nathan Binkert 2009-03-05 19:09:53 -08:00
  • e19fd1d521 stats: Add a wrapper class for the information side of things. This provides an easy way to provide the callbacks into the data side of things from the info side of things. Rename Wrap to DataWrap so it is more easily distinguishable from InfoWrap Nathan Binkert 2009-03-05 19:09:53 -08:00
  • c7bd1ec261 stats: better naming of template parameters for the wrapper stuff Parent and Child are bad names. Derived and Base are better. Nathan Binkert 2009-03-05 19:09:53 -08:00

  • 30cd2d21fa Remove unused functions/comments cluttering up the code. Korey Sewell 2009-03-04 13:17:08 -05:00
  • f69b018571 make handling of interstage buffers (i.e. StageQueues) more consistent: (1)number from 0-n, not 1-n+1, (2) always check nextStageValid before a stageNum+1 and prevStageValid for a stageNum-1 reference (3) add skidSize() to get StageQueue size for all threads Korey Sewell 2009-03-04 13:17:07 -05:00
  • f98e9161a8 InOrder didnt have all it's params set to a default value, which is now required for M5 objects; Also, a # of values need to be reset to 0 (or the appropriate value) before we assume they are OK for use. Korey Sewell 2009-03-04 13:17:05 -05:00
  • 846f953c2b Give TimeBuffer an ID that can be set. Necessary because InOrder uses generic stages so w/o an ID there is no way to differentiate buffers when debugging Korey Sewell 2009-03-04 13:16:49 -05:00
