    ALSA: dummy - Fake buffer allocations · a68c4d11
    Takashi Iwai authored
    Instead of allocating the real buffers, use a fake buffer and ignore
    read/write in the dummy driver so that we can save the resources.
    For mmap, a single page (unique to the direction, though) is reused
    to all buffers.
    When the app requires to read/write the real buffers, pass fake_buffer=0
    module option at loading time.  This will get back to the old behavior.
