As far as I see, the genalloc allocator doesn't allow to control the memory alignment when you allocate a chunk of memory. Two important notes regarding MURAM memory: - The allocated memory chunks should have specific alignment (might be different in each chunk). - The allocations must be efficient, we don't want to "waste" MURAM due to alignment issues. > - k -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
