But, we can store the latest commit ID of the guessed branch into file when CI system firstly tests the submitted patch or series and then generate the DPDK artifact based on that commit ID if we need retest the patch or series from the time when that patch was submitted. So, I estimate that Loongson lab can support this kind of retest. I figured that requesting a retest with some args can also be supported if we can parse these args correctly in get_reruns.py. > > If you can comment on this thread about whether it makes sense for the > Loongson lab, that helps us make sure we're not going in a direction > which will cause problems for other labs.
