From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tobin Davis Subject: Re: Sigmatel STAC9250 (7634) test patch 6 Date: Tue, 19 Dec 2006 08:55:03 -0800 Message-ID: <1166547303.25873.88.camel@razman> References: <1165941741.4142.10.camel@razman> Mime-Version: 1.0 Content-Type: multipart/mixed; boundary="=-E57frbDJHGOe8sJp1/oD" Return-path: In-Reply-To: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: alsa-devel-bounces@lists.sourceforge.net Errors-To: alsa-devel-bounces@lists.sourceforge.net To: Takashi Iwai Cc: alsa-devel List-Id: alsa-devel@alsa-project.org --=-E57frbDJHGOe8sJp1/oD Content-Type: multipart/alternative; boundary="=-XqczgJ+r61gEinJix95H" --=-XqczgJ+r61gEinJix95H Content-Type: text/plain Content-Transfer-Encoding: 7bit Unfortunately, it's not in good shape. I have 4 testers that all report kernel segfaults with this driver. Also, it appears as though we're getting the modem side of the codec instead of the audio side (this is a single chip solution from Sigmatel/IDT). I've done everything I can think of based on the datasheet and using other similar Sigmatel codecs as a guide (9200 is the closest match based on the data sheets). Attached is a sample dmesg output from one of the users. Here's a quote from one of them: I tried this patch and got similar results--still get a segfault trying to play with mplayer. Attached are dmesg.out and dmesg.out-ref which are the output of dmesg using no options as well as model=ref, respectively. In alsamixer the five bars that show up are Master, Capture, Caller I, Input So, and Off-hook. I don't have a microphone so I can't test recording. This one has proven to be more difficult than the Conexant stuff. From what I can tell, this patch should just work, but it doesn't. As you can see by the dmesg outputs, the pciquirk isn't getting handled. His particular subsystem id (from lspci -vn) is 107b:0461. I'm at a loss as to why this doesn't work.

Looks pretty good to me.
Pleas let me know if it's already in a shape to be merged.
