Did you add any armv4t processors with mmu? I believe the actual hardware I tested was an ARM920T. Vincent's patch claims to add arm920T, I tested yours because you claimed it was "more complete". I guess I should go test vincent's. > > What kernel .config, -M, and -cpu and did you use to test an armv4t > > system image with your patch? > > -M at91pes (which is included in other patches from around the same > time, but was never merged) "Included in other patches"... How _many_ other patches? And how far is "around"? If you'd like to resubmit them as a batch, I can try coming up with a kernel .config. (And a uClibc .config since I haven't actually tried a nommu system yet.) Thanks, Rob -- Latency is more important than throughput. It's that simple. - Linus Torvalds
