I poked at the pcm sound driver a bit, and it appears that sys/i386/isa/isa_dma.c:isa_dmastatus is returning 65280 (== snd_dmabuf bufsize == 0xff00) when there is no dma pending, which kinda blows the mind of sys/i386/isa/snd/dmabuf.c:dsp_wr_dmaupdate (which is easily confused). This breaks pcm audio. isa_dma.c seems to be new with newbus? I just thought the author(s) might be interested the know that this routine seems not to be returning what it claims in the comments. I don't suppose anyone has a document describing the ISA DMA hardware interface? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
