You'd use a store, just like you were already doing in trans_csrwr.
But here's how I'd improve this. For avoidance of doubt, all of this would go in
trans_priviledged.c.inc -- there's no use of csr_offsets[] outside of that file.
Thanks you very much, I had tested this with bios, it worked well, and I have two
questions.
1. CSRFL_IO, how to use it. I don't understand CPUState options
'can_do_Io',
Whenever a cpu touches a device, like a timer or clock, must have io flag set. Missing
this flag should result in assertion failures when running with -icount.
2./* fall through */, this may have warning, should we care about this?
It should not have a warning, as the comment itself should suppress that. For more
complex cases we also have QEMU_FALLTHROUGH.
