Hi, I'd like to measure line/branch coverage while testing UFSHCI device driver on FreeBSD. Which tools or workflow do you recommend for collecting coverage data from a device driver module? I've seen references to GCOV and KCOV, but I’m not sure which is the best fit for a device driver scenario. Thanks in advance, Jaeyoon Choi
