You are still using HTML, though, and you are top posting. Both should

So "generate some important information" is your end goal? Still a bit
vague / unclear to me, I have to admit...

So, to understand credit balance (which prints prv->credit_balance, as
you can see from csched_dump()), I recommend looking, inside
xen/common/sched_credit.c, at the csched_acct() function.

For credit, which prints prv->credits, look at __csched_set_tslice(),
csched_free_pdata() and init_pdata().
