The total code coverage they give is: Overall coverage rate: lines......: 11.2% (59584 of 530123 lines) functions..: 15.0% (7436 of 49443 functions) branches...: 6.3% (19273 of 303933 branches) We already get pretty close to that with the machine_aarch64_virt tests which only does one full boot (~120s vs ~600s) of alpine. We expand the kernel+initrd boot (~8s) to test both GICs and also add an RNG device and a block device to generate a few IRQs and exercise the storage layer. With that we get to a coverage of: Overall coverage rate: lines......: 11.0% (58121 of 530123 lines) functions..: 14.9% (7343 of 49443 functions) branches...: 6.0% (18269 of 303933 branches) which I feel is close enough given the massive time saving. If we want to target any more sub-systems we can use lighter weight more directed tests.
