Well, we haven't reached the consensus. The discussion faded away somehow mainly because I had too little time to update and ping people again.
In Tokyo, I talked with some guys regarding this. Ben agreed to take this approach for ppc, and David said that he doesn't mind for sparc part. Fujita-san mentioned it's no big problem to add one op from the generic dma_ops.
So, maybe somehow need to convince James in the end (and ask Paul to check SH part, too), then it'll be all up... theoretically :)
Anyway, I'm going to raise the discussion again on linux-arch. I'm afraid it's a bit too late game for 2.6.33, but starting now is better than too late again.
Hi, Takashi Iwai
Before the API stuff going into the mainline(2.6.33), can we apply this "[PATCH] MIPS: Fixups of ALSA memory maps"(This is the minimal necessares) as a current fixup. and then we will not get a broken sound support for MIPS, and also the support to the latest Loongson2F family machines will benefit from it.
and Ralf, what about your suggestion?
The question is whether this hack can be safely added for all MIPS platforms just by checking kconfig. I had an impression that rather many things have to be checked in the runtime.
As I have really little clue about MIPS architecture, I'd like let MIPS guys decide about it...
thanks,
Takashi
