Hi again, I made a mistake in my double buffering implementation. I assumed dma_unmap did not do any cache operations. Well, it does. Due to L2 read prefetch the L2 needs to be invalidated at dma_unmap. I made a quick test to see how much throughput would improved if dma_unmap could be run in par

1. Right now I do not have access to board. I think probably I can use QEMU for simulating my hardware. Yes, I expect so, but it won't be fast! Does the kernel not have a VFP emulation mode that might make the existing binaries work on your netbook, at least well enough for bootstrapping purp
