Change the bus_dmamap_sync() macro to test the ops argument against pre- and post- constants. The compiler will optimize out dead code because of the constants. Since post- operations are not needed on ARM (except for ISA bounce buffers), this eliminate a large number of function calls which are noops, each of which cost at least 6 cycles just in the call and return overhead (not to mention whatever other useless work the compiler decides to do in the callee). |
