Hi, I have followed the following link to setup DVFS system in ARM FS simulation. *http://www.m5sim.org/Running_gem5#Experimenting_with_DVFS <http://www.m5sim.org/Running_gem5#Experimenting_with_DVFS>*
One of the step cross compiles the kernel with the following compiler which compiles for hard float machines *arm-linux-gnueabihf.* However, when I cross compile the kernel with the above compiler and start the FS simulation and login from m5term, I could see that the compiler that kernel uses is for soft float machine and not for hard float machines *root@gem5sim:/lib# ls -l | grep -i armdrwxr-xr-x 3 root root 4096 2011-08-15 11:19 arm-linux-gnueabilrwxrwxrwx 1 root root 28 2011-08-15 11:14 ld-linux.so.3 -> arm-linux-gnueabi/ld-2.13.so <http://ld-2.13.so>* I have following three questions: 1) Shouldn't we cross compile the kernel with arm-linux-gnueabi instead of arm-linux-gnueabihf ? 2) When I cross compile my project with arm-linux-gnueabi and try to execute the binary in gem5 FS simulation, I get segfault throwing illegal instruction. Could you shed some light on this? 3) I am using the following options for cross compilation of my project *-march=armv7 -mthumb -mthumb-interwork -mfpu=vfp -msoft-float* Could you please let me know what other options could be required if options are any issue? Regards Rahul
