For example, I would like to know which memory is going to be allocated above 4GB. I don't know much about the kernel's async library, but my understanding is that fsldma does not allocate any of the memory buffers that it copies data to/from. The only memory that fsldma allocates is for the DMA descriptors, which are very small and probably don't take up more than a couple pages. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
