AC97 Registers...
Has anyone mapped them?
I made simple little program to query all the ac97 registers via kxctrl.exe -gac97 x and heres the output. Code:
AC97[reg=0]=1990 AC97[reg=1]=0 AC97[reg=2]=0 AC97[reg=3]=0 AC97[reg=4]=8000 AC97[reg=5]=0 AC97[reg=6]=801f AC97[reg=7]=0 AC97[reg=8]=0 AC97[reg=9]=0 AC97[reg=a]=801e AC97[reg=b]=0 AC97[reg=c]=8008

Are these registers mapped out somewhere - I will host them on a web page for easy reference, even if I have to map them my self. But any info on known ones will be a great help. Also, am I to assume than various AC97 codecs will have different registers? Like, are there some registers on some codecs that are not on others? My card shows up as; Quote:

Ответ: AC97 Registers...
>Seems like some registers are multiple bytes
>but I am confused why I dont simply see 1 byte for each register.... all registers are of 2 bytes size actually -gac97 command takes a memory address not really a register index (and same you see in the ac97.h, all registers have an even address) e.g. it doesn't make sense to read -gac97 3 for example - as there's no register there (well, logically "register" at address 3 is a half of register @2 and half of register @4  , but kxctrl just returns a dummy value for it (0 in this case)) >Has anyone mapped them? What (if i may ask) for?  (yes, there're certain vendor specific registers here and there, but i doubt if ac97 can have anything interesting - just by definition and max's spoiling the fun again!)Speaking of information, one starts with inventor's specification (http://download.intel.com/support/mo...b/ac97_r23.pdf) and goes further with vendor-specific docs (for example Integrated Device Technology, your codec seems to be "stac9750") (btw. it's something wrong with the dump above, registers [7c, 7e] should return [8384, 7650] (e.g. the values shown in kX's "about") P.S. >I was attempting to answer this post: ... ah, i see now. i suppose writing something like 0808 to reg10 should help

Re: AC97 Registers...
Thanks Max, your explanation made much sense to me...
Quote:
the 3d control register (h22) the ac97 spec shows more then the (edited) 4 states that kx mixer supports. And is shows 16 levels of 'effect depth' - I dunno, I think is somewhat interesting. Then I also see some EQ control register too... but for some reason (I imagine has to do with compatibility) not implemented in kX at all. Ok, not *really* interesting - but not completely worthless either. Quote:
Perhaps doing all them queries like I did in that batch file causes some errors? Edit: When running the batch file - kxctrl.exe will open my first card, which is a CT4832. While, opening kX console will use the currently selected device. So, those dumps are of a different card. /edit Thanks again for the links and info.
