1 month ago I think that is expected. The linux in ready-to-run is just a 'minimal' linux workload with a kernel that disables tons of feature and only runs an simple application software on it.
It's very possible that the defualt config worklaods is much bigger than minimal ones.
We are currently following this tutorial (https://docs.xiangshan.cc/zh-cn/latest/tools/opensbi-kernel-for-xs/) and (https://docs.xiangshan.cc/zh-cn/latest/tools/linux-kernel-for-xs/) to compile linux.bin. However, when using the emu_defconfig configuration, the output's scale is about ten times larger compared to the linux.bin available in the ready-to-run repository(https://github.com/OpenXiangShan/ready-to-run). Specifically, by the time it reaches the paging init instruction, the instruction count has already exceeded tens of millions.
Could you please advise if this behavior is expected or if there might be an issue with our configuration?
