Hi Andreas, No problem, I figured it wasn't the 80 char README file patch :)
I applied the 7 patches you posted this morning, but now when I run in dual mode, gem5 crashes with this: panic: M5 panic instruction called at pc=0xffffffc00008a024. @ tick 58408160 [execute:build/ARM/arch/arm/generated/exec-ns.cc.inc, line 241403] The GDB backtrace from gem5.debug suggests that execution is somehow killed from a manually inserted breakpoint. This is also after I had to hardcode the DTB file name for the drivesys in /src/arch/arm/linux/system.cc since it was not picking it up from the command line... warn: Kernel supports device tree, but no DTB file specified fatal: Expected a single ATAG memory entry but got 3 @ tick 58402784 [initState:build/ARM/arch/arm/linux/system.cc, line 202] Can you share how you tested the client-server configuration?
