Please, post proposed changes to the multimedia mailing first so at the very least the multimedia group can present a unified consesus agreement .
Thank You, Amancio
From The Desk Of Luigi Rizzo :
Ah, the light dawns. How about the next isa_dma* function Luigi has requested? Is the sanity checking in general a major problem from your point of view?
My right eye begings to nervously twitch ... Just joking .
I have no idea what Luigi wants to do next in the way of dma interface so him and I will have to "sit" down and iron out the functionality . I will let Luigi post the outcome of our discussion .
There is not much to discuss, basically I have proposed a new function, isa_dmastop(chan), which allows me to stop a DMA transfer. This _might_ be needed to implement functions such as PAUSE in a clean way (not sure the function is really necessary, since one can ni principle disable the DMA engine on the sound card and then do things as if the transfer had finished. But since I am not sure that all sound cards support disabling the DMA engine before a transfer is complete, I prefer to have an alternative way as well.
The code bloat is minimum and the reason why I want it to be in isa.c rather than in the sound driver is precisely what Steve Passe said, avoid subsystem fiddle with the hardware in uncontrolled ways.
Cheers Luigi
