XX_VirtToPhys(), by way of pmap_kextract(), is an expensive operation. Profiling via dtrace during a series of iperf tests I found 16111 / 30432 stack frames were located in mmu_booke_kextract(), so eliminating this expensive call should improve performance slightly. XX_PhysToVirt() is not as expensive, but redundant calls in this context is wasteful. |
