On Feb 8, I've reported maestro3 driver broken (please see a copy of a message below for details). I was wondering if anyone had a chance to have a look at this problem (it would be nice to have it working by the time 4.3 comes out). Many thanks, Vladimir ******************************************************* Date: 2001-02-08 11:00:36 PST > From: vladimir@math.uic.edu [[14]mailto:vladimir@math.uic.edu] > Sent: Thursday, February 08, 2001 10:29 AM > To: freebsd-stable@freebsd.org > Subject: maestro3 driver broken? > > I had no luck compiling a recently-committed driver for > maestro3 sounds cards.

I could compile the driver > before I did an upgrade (I believe my old sources were from > Jan 15, 2001, but I am not sure). 4.2-STABLE recently had the kobj changes from 5.0-CURRENT backported. I am moving to Scott Long's 5.0-CURRENT version, which should work in the STABLE now: http://people.freebsd.org/~scottl/maestro3/ That said, it doesn't work yet. It compiles cleanly and the module loads, but the attach fails. The driver's m3_pci_attach() calls pcm_addchan(), which in turn calls chn_init(). Then chn_init() calls CHANNEL_INIT(), but it doesn't invoke the driver's m3_pchan_init() as it should. The sound buf is never allocated, so chn_init() returns ENOMEM. I haven't had time to play with it much yet. The driver works in CURRENT; is there something different in the new method/class pcm framework between CURRENT and STABLE? -Darrell -- Department of Computer Science, Duke University, Durham, NC 27708-0129 Darrell Anderson, anderson -at- cs.duke.edu, [16]http://www.cs.duke.edu/~anders on To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
