Allow to specify mode in KCOV_IOC_ENABLE synchronizing the functionality with Linux, FreeBSD and OpenBSD. As a NetBSD (and OpenBSD) specific of the ioctl(2) interface, the mode argument has to be specified as &value rather than value. There are 3 modes available: 1. KCOV_MODE_NONE -- no trace specified, useful for testing purposes 2. KCOV_MODE_TRACE_PC -- trace the kernel program counter 3. KCOV_MODE_TRACE_CMP -- trace comparison instructions and switch statements Adapt the ATF tests and documentation for new API. The KCOV_MODE_TRACE_CMP mode is implemented but still awaits for the GCC 8.x upgrade or selection of Clang/LLVM as the kernel compiler. Obtained from OpenBSD and adapted for NetBSD by myself. |
