I did. I stuck an iccci -and- a dccci loop in. I threw in the tlbia when I ran out of other ideas. And the tlbia + existing flush_icache_range appears to be sufficient (tested on a non-trivial app). According to my docs, the 405fx's icache is virtually indexed/physically mapped, while the dcache is phys/phys. -- Mathematics is the supreme nostalgia of our time. _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
