Create ARM checkpoint from native environment

[bluechen8]

Hi,

I am new to gem5 and work on checkpoint creation in the native environment, hence speed up this procedure. The basic idea is to use gdb to dump register file and memory and then convert them to the gem5 format checkpoint.

Currently, I faced difficulties of how to do the conversion. The current reference I found used older version of gem5 (https://github.com/PrincetonUniversity/QPoints) and its script is not compatible to the new checkpoint file format. Meanwhile, the current gem5 checkpoint format makes me confused (I got it with gem5 save_checkpoint_generator on atomic arm cpu model). For example, there are 336 elements in Reg.integers and I have no idea what they are. Any suggestions? Thanks!!

regs.integer=152 230 72 0 0 0 0 0 176 231 72 0 0 0 0 0 224 238 72 0 0 0 0 0 240 230 72 0 0 0 0 0 0 240 72 0 0 0 0 0 208 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 80 248 72 0 0 0 0 0 78 0 0 0 0 0 0 0 48 0 0 0 0 0 0 0 0 208 72 0 0 0 0 0 0 128 74 0 0 0 0 0 112 248 72 0 0 0 0 0 88 248 72 0 0 0 0 0 31 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 152 230 72 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 128 74 0 0 0 0 0 0 0 73 0 0 0 0 0 26 0 0 0 0 0 0 0 228 15 64 0 0 0 0 0 44 15 64 0 0 0 0 0 148 255 254 255 127 0 0 0 0 224 72 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 152 230 72 0 0 0 0 0 48 0 0 0 0 0 0 0 112 234 254 255 127 0 0 0 44 237 64 0 0 0 0 0 0 0 0 0 0 0 0 0 176 234 254 255 127 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 112 234 254 255 127 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
