Re: [alsa-devel] Alsa MMAP emulation

I'm trying to get working Alsa with the PortAudio library on an embedded device (Nokia N810). The problem is that the sound driver is not an hardware driver for Alsa but a plugin which deals with the internal DSP of the device. This plugin doesn't support mmap'ing at all. So I was wondering if it is possible to configure Alsa a way such PortAudio can use mmap'ing on my DSP plugin ? I saw there is a mmap_emulation flag but the problem is that it seems to be only available on HW driver and not on alsa plugins.

In alsa-lib 1.0.15, this function was moved into the mmap_emul plugin.
