I defined TLB object tlb2 in mmu.cc file, and added tlb2 access process in getTE() function of tlb.cc file to realize simple two-level TLB. It can be compiled successfully, but it can't enter benchmark test set at runtime. I used Command line is：./build/ARM/gem5.opt /home/gem5/configs/example/fs.py --debug-flags=TLB,TLBVerbose --cpu-type=O3_ARM_v7a --caches --l2_size=2MB --l1d_size=512kB --l1i_size=512kB --l1d_assoc=8 --l1i_assoc=8 --l2_assoc=16 --script=/home/full_system_images/rcS/CPU06/450.soplex.rcS --kernel=/home/full_system_images/binaries/vmlinux.euler --disk-image=/home/full_system_images/expanded-linaro-minimal-aarch64.img
I test run this command line in eclipse,the debug flags output not stopped,but the m5term terminal has stopped running in the following for a long time.

Or is it appropriate for me to add TLB like this?
