@Kai, the performance improvement seems not so giant, but the method
looks good, indeed. However, to keep the consistency of the code, I'm
wondering why you only use the perf_ref for wr_tx_wait, but not for
wr_reg_refcnt?
Didn't check the similar refcnt, my bad.
On the other hand, Our work is inspired by performance analysis, it
seems wr_reg_refcnt is not on the IO path. It may not contribute to
performance improvement.
And inspired by your comment, it seems we can also make the refcnt
cdc_pend_tx_wr a perfcpu one. I will look into this.
Thanks
