Updated AUICH driver crashes media_addon_server ...

[herdemir]

Tested with r25522.

I tested the updated AUICH driver(r25497) and it crashes media_addon_server landing to KDL.

Trac doesn't allow images higher than 500k. Here is the link to the screen shot.

Seems not related to AUICH driver ... Similar problems : #2228, #2213

Could you give the top of the screen (before Welcome to the kernel land) ?

[herdemir]

Uppps! sorry ..

It should be:

PANIC: vm_page_fault: unhandled page fault in kernel space at 0x41445303, ip 0x800abcb7

If you need a new complete screenshot I can give it toworrow. As additional information:

• It does not crash under GCC4 version of Haiku. But still cannot test the driver because of another crash which is not related to the media_server or to the driver. (Out of Topic: Should I file tickets for crashes that occours in GCC4 version, but does not occour in GCC2 version?)

My laptop (Dell Inspiron 1100 with i845 and ich4 chipset) just started to crash with the auich driver similarly as well. It just started to happen after the recent auich changes I think.

It never did work properly with the auich driver before either - making horrible noise when trying to play sound, and then a bunch of crackling sounds when I rebooted out of Haiku. I've been too lazy to report it, but now that it crashes, it's clearly something that I should report.

I can also provide some serial logs for my laptop, but not until the end of this week (since I'm out of town currently using the laptop for business).

Could you try again with r25562 please ?

[herdemir]

It seems it is fixed, thanks. Now I tested the updated driver, but I couldn't get any sound. I looked at "Media Preferences" and saw in "AC97 mixer" that all controls were muted. (not the Audio Mixer but AC97 Mixer) So I unmuted them but there wasn't any change. Closed the Preferences windows and opened it again. And again the AC97 Mixer controls were all muted, even tough I changed them for sure. Seems it doesn't change the setting.

AUICH log file while DEBUG enabled

[herdemir]

AUICH log file while DEBUG disabled (from syslog)

[herdemir]

It's funny, when I enable debugging from debug.h it just works. When i disable again it brakes again. I noticed that it finds Vendor ID in DEBUG mode, but not in NON-DEBUG mode. I attached the log files.

I hope it helps ...

Tested with r25563.

[herdemir]

Added a patch which could fix the above problem. (The fix works for me).

[korli]

Looked in the patch. Weird, did the driver work before the ac97 regression ?

[herdemir]

AUICH log after the fix (from syslog)

[herdemir]

I didn't have any problem before the AUICH update. And also i tried several times after my fix, actually it does not fix completely. But it fixes the problem with the codec Vendor id retrival. Even tough it finds the codec id correctly sometimes i can't hear any sound.(I could hear in debug mode). Will try to increase the snooze time and see what happens.

I updated a bit the ac97 reset in r25566. Hope it can help.

[herdemir]

FINAL patch

[herdemir]

The last patch fixed it completely, for me.

I think the problem is after the cold reset initiated, it doesn't wait enough to finish the cold reset.

[herdemir]

Upps didn't see your patch. will now test it ...

[herdemir]

Works great! Thanks. :)

[korli]

Thanks for testing and your patience :)

[korli]

Could you check it's still working with r25574 ?

[herdemir]

Tested and works fine! ;)

[herdemir]

You seem to forgot the comma after "Philips", i think after r25589.

 	"ESS Technology",
 	"Harman International",
 	"Nvidea",
-	"Philips",
+	"Philips"
 	"Texas Instruments",
 	"VLSI Technology",
 	"TriTech",

Also working properly on my Dell Inspiron now (never did before!)

Thanks!
