Much faster git grep when this happens.

normally, this should not happen, I just want to use this to tell the case owner that he/she should setup up check point.
could you please explain more on git grep?

When someone sees the message with KERNEL_CHECKPOINT then they can immediately git grep that and find all relevant locations in sof-test.

This still belong to a different PR but OK, it's in a different commit and it's a small enough change. Small in number of lines, not in consequences...

Can you please

  1. Add this to the comment:
# There is a 5s delay between two cases by sof-framework,
# make the check point 5s earlier to avoid log loss.
# Note this can make an error caused by one test appear in the next one
  1. Make the 5s a global, $SOF_TEST_INTERVAL variable and use it here?

In an ideal world every commit should be usable for bisecatability, cherry-picking, reverting, etc. reasons. I guess this implies the entire DMESG_LOG_START_LINE removal should be a single commit? Good the second commit does not even have a commit message :-)

-k implies --boot, please remove this.

Feel free to expand -k to --kernel. Short options are meant to save typing time on the command line but they are less readable in scripts which are read many times more than they are written.

Can you add a comment explaining why this one needs the export when the others don't?

Wouldn't it be simpler to export KERNEL_CHECKPOINT always? If not why not?

Sorry, this is a mistake from previously version, the export KERNEL_CHECKPOINT should be removed.
