Hello, on ARM using dfu mode we've seen problems with dma memory allocations. Some drivers use dma_inv_range on allocated buffers, which corrupts memory around the buffer, it it's not aligned to cache lines. This series introduces: dma_alloc() and dma_free() that allocate memory aligned to cache lines. This is 64 bytes on ARM (just to be sure) and DCACHE_LINE_SIZE on nios2. All other arch do a transparent xmalloc. Feel free to add the appropriate alignment for your architecture to "include/asm/dma.h" regards, Marc _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
