What is Direct Memory Access (DMA) and Why Should We …

• Note: other buses (e.g. Sbus) use virtual memory addresses for the transfer • The right kind of memory must be allocated since not all memory zones are suitable: high memory may not work with some devices because of limited address space • Memory can be allocated at boot or runtime but drivers can only allocate at runtime

4.3BSD allocates swap space when process starts; holds text segment (the program) and data segment. Kernel uses swap maps to track swap-space use. Linux and late versions of Solaris only allocate swap space when a page is forced out Linux supports multiple swap partitions, and suggests that they be at
