In this case no one has taken the incentive to push the technology. Few hackers express any interest at all on PnP at the time that Sujal and I where working on the PnP code. Nevertheless , we are thinking about the rest of the system and Luigi is leading the effort to iron out the PnP interface. As for ISA DMA support, the sound drivers from day one have used the isa dma subsystem. In order to support linux applications such as xquake and for improved sound support we were forced to add isa_dmastatus which Luigi was kind to provide. The contributed code naturally didn't break the sound driver functionality however the version that made into current did. At the very least someone should have consulted someone in the multimedia group to see if this was okay to change . As part of the guspnp sound driver release , the linux emulation has been modified to support the sound driver 3.5 ioctl. I can't check that version in because the changes are specific to support the sound driver 3.5 ioctl interface which is not present in FreeBSD.XXXX sound driver release. Amancio
