Hi Takashi, Great, it's good to hear that you are able to assist with adding the DSP loader modifications to hda_intel.c.

I've attached a draft patch as you requested. Please let us know if you have any questions concerning it. The first patch is the previous update to add DSP features to patch_ca0132, then the second is the draft patch, to add the new DMA loader calls.

Well, for cleanness, I think we should start rather from scratch:

- The first patch to add a new hda_bus_ops for DSP transfer; it won't touch patch_ca0132.c but only the core part (hda_intel.c, hda_codec.[ch])

- Add the DSP transfer to patch_ca0132.c; at this point, just do DMA transfer but no new mixers etc won't be added

- Add new features to patch_ca0132.c

At the early development stage, the first two items can be a single patch. We can split to two when applied to the upstream. But, mixing all changes in a single patch is pretty bad. So the point is to concentrate only on DMA transfer stuff at first. Once after confirmed it's working, continue to the new DSP features.

We're also currently ascertaining the license information to go along with the firmware binary release.

Good. This is really mandatory for upstreaming.

The project team would like to know, beyond the outstanding items mentioned above, do you see any other potential issues with the updates to the codec that could possibly slow the submission process? We're starting to get rather close to our target date. Also, once the codec has made it into the ALSA tree, how long do you estimate it would take before it is upstreamed to the Linux kernel? If you could provide any info on the timeframe for this process, we'd greatly appreciate it.

Heh, this depends on how hard we work :) If it can be quickly done, it'll be merged even in 3.7 kernel.
