[gem5-users] gem5 terminated earlier
Hi all I run gem5 X86 in FS mode.But in some application of PARSEC 2 gem5 terminate earlier. In system.pc.com file for the ferret application show this error: [HOOKS] PARSEC Hooks Version 1.2 [HOOKS] Entering ROI (4,1) ferret[2093]: segfault at 0 ip 004089ba sp 7f33ebf4c380 error 4 in ferret[40+5b4000] Segmentation fault Done :D Or in the swaptions application shows: [HOOKS] Entering ROI swaptions[1932]: segfault at 56ec30 ip 00477dd7 sp 7fe0737f5270 error 4 in swaptions[40+157000] Segmentation fault Done :D But also in some application terminate correctly. Do you have any suggestion what I should do to solve this problem? Here is the command line that I've used for the simulation. ./build/X86/gem5.fast configs/example/fs.py --cpu-type=timing --script=run_scripts/ferret_64c_simsmall.rcS --ruby --network=garnet2.0 --mesh-rows=8 --topology=Mesh_XY --routing-algorithm=1 --num-cpus=64 --num-dirs=64 --num-l2caches=64 --l1d_size=32kB --l1i_size=32kB --l1d_assoc=4 --l1i_assoc=4 --l2_size=128kB --l2_assoc=8 --kernel=/home/rashid/Desktop/gem5/X86_DISC_BINARY/m5_ system_2.0b3/binaries/x86_64-vmlinux-2.6.28.4-smp --disk-image=/home/rashid/ Desktop/gem5/X86_DISC_BINARY/m5_system_2.0b3/disks/x86root-parsec.img ___ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
[gem5-users] RISCV tool-chain commit point used for Gem5+RISCV
Hi Gem5 users,
Can someone tell which commit point and branch in the riscv-tools repo (
https://github.com/riscv/riscv-tools ) was used for the development of
RISCV in gem5? I was trying to run a simple hello world program compiled
with the latest version of the compiler ( commit point 7b1680 in
riscv-tools trepo ):
1 #include
2
3 int main( int argc, char* argv[] )
4 {
5 std::cout << "Hello World, RISC-V!" << std::endl;
6 return 0;
7 }
and compiling it and running it on gem5 gives error:
% riscv64-unknown-elf-g++ hello.c -o hello
% spike pk hello
Hello World, RISC-V!
% cd gem5
% ./build/RISCV/gem5.opt ./configs/example/se.py -c hello
gives the following error:
warn: DRAM device capacity (8192 Mbytes) does not match the address
range assigned (512 Mbytes)
warn: Unknown operating system; assuming Linux.0:
system.remote_gdb.listener: listening for remote gdb #0 on port 7000

Seeing the object-dump for hello at pc 1036e shows:
