SPEC2006 profiling is failed #271

After I modify the script, the profiling is still failed

following is my profiling-out.txt, and profiling-err.txt is blank

YudeFang · 2024-02-28T02:00:42Z

here is my bbl.bin,I wonder which step is wrong.generate spec2006-workload ?or the configs of NEMU?
bbl.bin.zip

xiaokamikami · 2024-02-28T07:41:34Z

The error address should be the bbl entry point after loading gcpt restor. You should check the start address of the bbl disassembly. When using checkpoint recovery, you should offset the start address of bbl by a0000

YudeFang · 2024-02-28T10:04:25Z

it seems wrong when I rebuild my bbl.bin,i didn't see this before. I search my ./riscv-rootf/rootfsimg/build,it seems other documents was all correct except busy box

xyyy1420 · 2024-02-28T10:11:29Z

please RTFM

YudeFang · 2024-02-28T10:12:38Z

what do you mean RTFM?please specific,thank

I have update my riscv-rootfs to the newest checkpoint branch release ,but meets a new issue it seems /init can't find libm.so.6:
but in initramfs-spec.txt ，I really set the correct path for libm.so.6

profiling这一步出的问题，找了很久也google不到原因，这个文件按道理已经添加到busybox的/lib/目录下了，但是执行的时候出现了这个问题

shinezyy · 2024-03-01T09:02:47Z

/init: error while loading shared libraries: libm.so.6: cannot open shared object file: No such file or directory

这个报错是因为没找到libm这个库。要么把它放到init ramfs里，要么静态链接你的应用避免使用动态库。

YudeFang · 2024-03-01T18:23:00Z

file /lib/libm.so.6 ${RISCV}/sysroot/lib64/lp64d/libm.so.6 755 0 0 这句不是已经放在initramfs里了么路径也没问题

YudeFang · 2024-03-07T06:19:11Z

问题解决了，run.sh脚本中加入export LD_LIBRARY_PATH=/lib
