[gem5-users] Simulation terminates successfully on one machine and runs into assertion failure on another
Hello All, I am trying to run the same experiment (ARM full system with RUBY MESI_Three_level that boots from checkpoint) on two different machines. It terminates successfully on one but runs into assertion failure on the other. This is the terminating message: Addr Request::getPaddr() const: Assertion `privateFlags.isSet(VALID_PADDR)' failed I tried running with the Exec debug flag and comparing both traces. This is the difference I found: < 47134939: system.cpu_cluster.bef_roi_cpus0 T0 : @ext4_iget+1244: ldrsw x2, [x21, #8]: MemRead : D=0x5e41dd0c A=0xffc07b1ce008 < 471349390500: system.cpu_cluster.bef_roi_cpus0 T0 : @ext4_iget+1248: str x2, [x19, #80] : MemWrite : D=0x5e41dd0c A=0xffc07c205d00 --- > 47134939: system.cpu_cluster.bef_roi_cpus0 T0 : @ext4_iget+1244: ldrsw x2, [x21, #8]: MemRead : D=0x5e4ebbdf A=0xffc07b1ce008 > 471349390500: system.cpu_cluster.bef_roi_cpus0 T0 : @ext4_iget+1248: str x2, [x19, #80] : MemWrite : D=0x5e4ebbdf A=0xffc07c205d00 17299344d17299343 < 474920248000: system.cpu_cluster.bef_roi_cpus0 T0 : 0x7fbf4f9510: su Any ideas how I should proceed with debugging this problem?

Re: [gem5-users] [Questions] how to use the new GEM5 website
Hi, Jason For example, in the events page, all the links of "HiPEAC Computer Systems Week"(held in Gothenburg, Sweden in April 2012) will direct to 404 error. In the documents page, API documents https://gem5.github.io/gem5-doxygen/ will direct to 404 error. Currently I found these, if have some new failed links, I will report to this mail group. Thank you very much.

[gem5-users] Sysmalloc assertion
Hi all, I wrote a script that executes several gem5 simulations. It works perfectly on my laptop but when I clone it to the workstation I am getting this error: pr(This is the applications name): malloc.c:2389: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed. warn: need to stop all queues Trace/breakpoint trap (core dumped) Compiler versions etc are the same with my laptop. Does anyone have an idea about this? Best, Muhammet ___ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
