Hello Fengguang,
I hope this email finds you well. We dug into the regression detection tool and discovered things like lib/compare and reports such as [1] clearly showing that LKP is able to do some regression analysis.
TBH, I'm a little confused as to what the regression detection tool we discussed is meant to do given that the functionality is already present in LKP. I recall you mentioning that CompassCI doesn't do regression detection so I might have misunderstood your statement or something got lost in translation. Our intention is to create a benchmark data analysis and regression tool that can be used by both CompassCI and LKFT.
Let me know what you think please. We can always jump on a call to sort this out if need be.
