Hi all, I'm new to Gem5. When I try to run Gem5 in Full System mode for x86 architecture with --mem-size=16GB, on the master terminal I get:
"warn: Physical memory size specified is 16GB which is greater than 3GB. Twice the number of memory controllers would be created." and simulation gets aborted after showing (on the master terminal): "fatal: Could not mmap 13958643712 bytes for range [0x100000000 : 0x43fffffff]!". In case of --mem-size=8GB, I get the same warning (on the master terminal): "warn: Physical memory size specified is 8GB which is greater than 3GB. Twice the number of memory controllers would be created." but it runs and after showing: "Initializing CPU#0 Checking aperture... No AGP bridge found PCI-DMA: Using software bounce buffering for IO (SWIOTLB) Placing 64MB software IO TLB between ffff880020000000 - ffff880024000000 software IO TLB at phys 0x20000000 - 0x24000000 Memory: 8183752k/9437184k available (4469k kernel code, 1048964k absent, 203544k reserved, 2815k data, 376k init)" on the slave terminal simulation gets aborted. I have looked into the discussion at http://comments.gmane.org/gmane.comp.emulators.m5.users/17539 and the source code at /configs/common/FSConfig.py but could not solve the problem. The command line used is: ./build/X86/gem5-MESI2L.opt ./configs/example/fs.py --disk-image=linux-x86.img --kernel=x86-vmlinux-2.6.22.9.smp --cpu-type=timing --ruby --num-cpus=16 --mesh-rows=4 --num-dirs=4 --mem-type=DDR4_2400_x64 --mem-channels=4 --mem-size=8GB --topology=MeshDirCorners Any help will be highly appreciated. Thanks. _______________________________________________ gem5-users mailing list [email protected] http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
