Dear colleagues, We are researchers at Inria (France) working on software configurable systems in general. Recently we have made lots of effort with Linux: we have basically build 95K+ configurations using ranconfig. Our attempt is quite similar to KernelCI, the platform you’ve developed. We have developed some techniques to identify what (combinations of) options lead to a failure (a non-trivial problem!), with two main applications in mind: (1) configuration bug location/understanding (2) preventing configurations’ build that will anyway lead to a failure. We mainly use randconfig. More details can be found here: https://hal.inria.fr/hal-02147012 We have also made some efforts about predicting kernel sizes: https://hal.inria.fr/hal-02314830 It would be very nice to know more about your infrastructure, your strategy for sampling configurations, and basically your insights. We can also chat a bit about our approach and potential complementarity. Would you be available for discussing? I guess some of you will be at OSS in Lyon. I’m giving a talk on Wednesday https://sched.co/TLKI and I’m here until Thursday (included) Best regards, Dr. Mathieu ACHER, Associate Professor Univ Rennes, Inria, CNRS, IRISA, France (DiverSE team) http://www.mathieuacher.com/
