You wouldn't normally define DEBUG for everything, just for the particular files/areas you're interested in (and in many cases they're called "<subsystem>_DEBUG" rather than just "DEBUG"). Are you just after a kernel with debug symbols? If so, that's done with makeoptions DEBUG="-g" in kernel config. Otherwise target the particular area, it's usually simplest to edit the relevant source files. If you are actually wanting to debug iommu, the DPRINTF format strings will need fixing up, I expect they haven't been built this way since at least the time_t/off_t changes. > ../../../../arch/sparc64/dev/iommu.c:569: warning: format '%lx' expects > type 'long unsigned int', but argument 4 has type 'time_t' > ../../../../arch/sparc64/dev/iommu.c:569: warning: format '%lx' expects > type 'long unsigned int', but argument 6 has type 'time_t' %llx > ../../../../arch/sparc64/dev/iommu.c: In function 'iommu_dvmamap_load_raw': > ../../../../arch/sparc64/dev/iommu.c:1020: warning: format '%ld' expects > type 'long int', but argument 5 has type 'int' %d > ../../../../arch/sparc64/dev/iommu.c:1020: warning: format '%lx' expects > type 'long unsigned int', but argument 6 has type 'int' %x > expects type 'long long unsigned int', but argument 2 has type 'bus_addr_t' > ../../../../arch/sparc64/dev/iommu.c:1352: warning: format '%llx' %lx > expects type 'long long unsigned int', but argument 2 has type 'bus_size_t' > ../../../../arch/sparc64/dev/iommu.c:1360: warning: format '%llx' %lx etc.
