WebDec 22, 2014 · mmap() attaches file to RAM, so after mmap call, any reads from memory range will lead to reads from file, any writes will be flushhed to disk (by OS, msync, munmap). If You can't get DMA buffer address before DMA completes, I'm afraid mmap() will not offer speed advantage compared to simple write().Probably You need to dig …
