What would be the best way to read/write from a device that shows up on boot, but there is no device node for it? Basically what I am trying to do is to be able to send to commands to the csa device so that I can control the breakout box for my GameTheatre XP so I don't get cracking and popping since it isn't outputting the sound through the device correctly with just pcm. I have looked at the /usr/share/examples/kld made a few modifications to make it create my own device node. How should I access the csa device so that I can have my module send commands? --- relevent dmesg output --- csa0: <CS4280/CS4614/CS4622/CS4624/CS4630> mem 0xdd000000-0xdd0fffff,0xdd102000-0xdd102fff irq 5 at device 10.0 on pci0 csa: card is Hercules Game Theatre XP pcm1: <CS461x PCM Audio> on csa0 Thanks, -- Anish Mistry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
