Dear m5-users, I am trying to get the SPEC2000 eio traces to run on M5 with InOrderCPU in SE mode. I built m5 with "EXTRAS" support using this command:
scons EXTRAS=/path/to/m5_2.0_encumbered build/ALPHA_SE/m5.debug To run the eio traces, I modified the "se.py" script following Michael's direction (http://osdir.com/ml/emulators.m5.users/2006-10/msg00013.html). Then I use the following command: ./build/ALPHA_SE/m5.debug ./configs/example/se.py --inorder --caches --l2cache --eio=/path/to/EIO_traces But I got core dump and the error message as following: **** REAL SIMULATION **** For more information see: http://www.m5sim.org/warn/7f11c91a info: Entering event queue @ 0. Starting simulation... panic: Tried to execute unmapped address 0. @ cycle 58000 [invoke:build/ALPHA_SE/arch/alpha/faults.cc, line 186] Memory Usage: 547308 KBytes For more information see: http://www.m5sim.org/panic/95542d88 Program aborted at cycle 58000 gzip: Abort (core dumped) stdout: Broken pipe ================================================== I installed several versions of M5 (with support for InOrderCPU model) from the repository and got the same error message. I printed some traces, it seems that there is bug in "Fetch-Seq-Unit" which assigns dynamic instruction to PC 0x000000 (From trace: "58000: system.cpu.Fetch-Seq-Unit: [tid:0]: Assigning [sn:3] to PC 0x000000, NPC 0x000004, NNPC 0x000008"). I looked into the source code of "cpu/inorder/first_stage.cc" and related files but still cannot figure out the problem. I wonder if someone met the same problem before (at least I haven't found solution from the list archive) and how to make it work correctly. Any help would be greatly appreciated. Thanks in advance. Best, Jing _______________________________________________ m5-users mailing list [email protected] http://m5sim.org/cgi-bin/mailman/listinfo/m5-users
