CORB (Probably a bit esoteric)

codeye 01 Nov 2008 17:19

I've put together another frontend utility for reggie_se to examine physical memory blocks in a more user friendly way - memory_dump0.1 (usual place).
Here are the first azalia dumps from the Command Output Ring Buffer (CORB) ie what azalia is sending to the codec.
I didn't want to fill up the main discussion thread.

HDAController Azalia correctly sets up an output stream at iomemory+0x100, and can be interacted with (crudely at present).
HDAController HDA sets up an output stream at iomemory+0x100, but there is no change in the Link Position in Buffer (LPIB) suggesting no bytes are transferred of the link into the codec.
http://svn.berlios.de/viewcvs/haiku/haiku/trunk/src/add-ons/kernel/drivers/audio/hda/?rev=28478
this may be adaptable for a userspace program to interact with the controller.

Re: CORB (Probably a bit esoteric)

Toonces 03 Nov 2008 22:54

codeye, which codec are you using when testing the LPIB? I am wondering if the 262 & 885 might be dead ends. When I tested the AppleHDA.kext MadTux provided he seemed to indicate that the 885 codec was setting things up but not passing through any of the additional verbs we needed and switched to using one of the sigmatel codecs (the 9220 I think). Maybe you can try the last test AppleHDA.kext he uploaded (http://www.speedyshare.com/806961393.html) and see what is going on? That one seemed to have everything right in IOReg at least. Still no sound though. The only thing I keep seeing is that there are no mute controls and I have to think that has something to do with no sound even when I inject the EAPD verb it was silent.

Re: CORB (Probably a bit esoteric)

toonces,
I've tested so many different incarnations of these kexts my head is spinning!
Up until now I have not been sure why there is no sound (ie could it be the amps turned off, not powered up, volume wrong etc).
The root problem it seems is that the controller sets up a stream to be sent to the codec but the link is "malformed".
Can this be overcome with the right incantation of verbs - possibly, and I would encourage everyone to keep trying, but I'm also wondering if I can hack the controller to get around this problem or whether it can be bypassed altogether.
What would be useful would be for someone with a 268 based hackintosh to load up a non-functional hda kext (but one that loads and appears to play a stream) and see if the controller registers are set similar to mine on the 269 ie output stream is set up but link isn't advancing this would suggest getting the verbs in the correct order will work. It might be that like the azalia inconsistencies we were having that firing all those verbs through the codec for the 268 just meant that the crucial one for EAPD was also sent by chance (I hope not).
Toonces, grab the hdaudio_03.pdf and have a look at how the registers are setup for the controller (it sits at 0xF7DB8000 on the 901).
You can see the HDAcontroller.kext is interacting with it (particularly with azalia loaded up and a stream playing), when you change sample rates this changes in the controller registers and you can stop a stream with the correct byte writes (using graphical reggie_se).
Maybe it is just a matter of getting the verbs correct…

Will do codeye! The AppleHDA.kext that MadTux posted last seems to me to be very close to what it should look like from what I can tell in IOReg. All of the streams are there just no sound and no mute control. I can turn the EAPD on and still no sound so maybe it's just muted. I'll take a look at that pdf and see if I can make heads or tails of it (You are light years ahead of my understanding. Ok, maybe a couple days and a few explanations but still more than what I currently understand). I'll try running your memory_dumper program tomorrow after I tear down my Audieee setup and reinstall that codec so we can see what it shows.

EDIT: Nope Light years was right. I think I sprained my RIRB trying to understand the CORB when I stepped in the stream.

Re: CORB (Probably a bit esoteric)

I've been patiently watching your progress in this area… CORB is something I read about in my HDA spec research too but I never thought we would have to go so low level since the gurus that came before us never needed to themselves (at least, it never seemed so).

The symptoms that you are observing certainly correlate well with the way Apple has been evolving their HDA kexts… from the Azalia single kext to the early HDA kext with 3 separate subkexts and now the newer HDA kext with 5 subkexts and it just seems that they are making it more and more complicated.

Or rather, they are delegating out functionality to subkexts what was once taken care of by a single codebase.

My suggestion would be to take a step back… you have already uncovered the subtle differences in why it's not working, perhaps we need to go back to routine level rather than memory/byte level, and see if there isn't a simpler way to trick the code into working for us. Although, I do agree that the ultimate solution is likely to be verb level, I guess I'm just saying, you've been staring at registers for so long you would do well to take a step back, a deep breath, and a quick look at human readable text rather than binary. ;) To this end, I will prep some disassemblies and decompilations of both old and new AppleHDA binaries as well as the controller and generic driver (hell, Azalia too while I'm at it) to see if there isn't some binary patch that would solve our problem faster. Previously I have only been looking at a single decompilation of the new AppleHDA (10.5.5) but all the research shows the importance of the progression of the driver.

What would really really help is if we could debug the kext live in memory, the way that SoftICE in windows let us look at running device drivers. Unfortunately, I am unwilling to do instruction stepping using gdb ;p We will probably have to settle for dead list, text file approach. You guys have been doing your disassembly with otool and its brothers, I assume, and I have been using… something else.

As posting decompiled source is probably tantamount to piracy (also considering the tools required to produce it), I will prepare these text files and distribute them to the team via PM, hidden link, password protected archive.

codeye, Here's teh dump from the last AppleHDA.kext that MadTux sent me with no extra verbs injected. This one looks to be very close to working as I said previously since all of the streams are set up. I really think it has something to do with why there are no mute controls. This kext is using one of the stac codecs instead of the ALC262 or ALC885 codec.

Re: CORB (Probably a bit esoteric)

I was a bit skeptical when MadTux proposed to use the stac codec routine path instead of the realtek codec routines, but if this works, I have to wonder why… Does anyone know, historically, which codec chip was used in the first Intel Macs? Perhaps the routine path for the stac codec is similar to the original Azalia driver? If patching the HDA kext to use the stac codec brings us back to Azalia functionality, then all we would have to do for all future iterations would be to use this path plus the proposed VerbSyringe approach to get full audio on the ALC269 and future codecs.

Re: CORB (Probably a bit esoteric)

codeye 05 Nov 2008 23:45

Thanks for adding your thoughts guys, it may take a bit longer to sort this out than we hoped!
I think using the alc262 routines was a great idea as the alsa patch suggests the alc262 and the analogue component
of alc269 are very similar. I also think we need to work out which subroutine is not firing (and why) as it seems virtually all the kexts I load up set the streams correctly (input at f7db8000+0x80, output f7db8000+0x100 & f7db8000+0x120) but despite setting the run bit in the stream (in software) it doesn't run - in Azalia if I set the run bit it runs the stream but without sound.
Toonces even without a loading kext the HDBAR gets setup as above the interesting bits occur at HDBAR+0x100-0x120.
Mutes may be important (at present I'm not sure of anything) but people have reported working HDA without mute working (I think), it would be nice to have a working sound hackintosh to compare maybe hagglebeef can let us know when the aspire works.
Snickersmd, I have looked at the decompiled azalia and hda controllers and they are VERY similar, I'm thinking my next approach will be to NOP or RET many of the extra routines in HDAController binary and see what happens (again it would be best to be able to do that on a working hackitosh with sound and see what you can remove safely) - I know noone has had to do this to get working sound, but there are a lot of failed attempts with just plugging in verbs and node settings.
If you can get more detailed decompilations please do [source code would be great ;-)]

Re: CORB (Probably a bit esoteric)

snickersmd 06 Nov 2008 01:13

@codeye

More detailed decompilations? How about C pseudocode? Not just disassemblies but true decompilations?

I've decompiled every single kext and subkext from Azalia, AppleHDA older and newer.

Check your PMs for the download link. If any other sound dev wants the file, PM me. DEVS ONLY.

guys - a bit off topic, but do you know if reggie_se can be used to read/write I/O space registers? the graphical app "Reggie" can do this but it would be a heck of a lot easier to do what i'm doing from the command line… from the man page and help for reggie_se it seems like it just can't do it, but since Reggie can do it it seems a bit strange that they would leave this functionality out of reggie_se.
