Not all BSPs follow the split between developer and production, but see how it is used in: bsp/common-pc-64/common-pc-64-developer.scc:include features/profiling/profiling.scc bsp/common-pc-64/common-pc-64-preempt-rt.scc:include features/profiling/profiling.scc If it was enabled by default, it really should be in the developer ktype and then BSPs could have the split between production and developer/debug in their definitions .. with the developer ones getting profiling by default.
