I have the 2.3.52 kernel from Paul's tree, with PowerMac DMA sound support compiled in. I guess my question is: what is thecurrentquoted
state of sound support in Paul's 2.3.52 kernel?My primary distribution source is also LimuxPPC. Geert Uytterhoeven posted a patch to split the DMA sound support between Pmac, Atari etc. a while ago (look for dmasound split).Okay, I applied the patch (and the patch to the patch) that I found in the list archives. It built fine, but upon reboot, sound doesn't work at all (no beep even). I tried building both Sound Support and PowerMac AWACS support as modules, and it produced one module called soundcore.c. I rebooted with this kernel and insmod'ed it, and it still doesn't work, although /dev/dsp and /dev/mixer existed this time. Any clues? I've got a UMAX S900, which, IIRC is a 9500 clone.
Yes (I think) - I should have posted a patch for this. in drivers/char/mem.c there are two areas in which calls (and its declaration) to init_dmasound() are conditional on CONFIG_DMASOUND - but CONFIG_DMASOUND has been removed. You need to change those lines to something like... #if defined(CONFIG_DMASOUND_AWACS) || defined(CONFIG_DMASOUND_ATARI.... or whatever (the various CONFIG_DMASOUND_XXXXX are visible in the Makefiles) Sorry about this - I was very new to the list and carried out some of the discussion without doing cc's ;-) I think that is it - basically you have everything complied in - but it isn't being called at init time.
