Hi all!
Here's another revision of the ATI/AMD multichannel+HBR patchset.
Changes:
- added customizable callbacks instead of polluting generic code
- fixed wrong codec id in rev3+ check (as previously noted)
- cosmetics
I've only tested this on NVIDIA/Intel, but I'd guess at least Peter should be able to test this on AMD in a few days or so. The earlier revisions were tested to fully work.
Combined patch can be found at: http://onse.fi/files/atihdmi5.patch However, this patchset is on top recent sound-next commits so it does not directly apply on older kernels.
Olivier, I hope you will be able to test this at some point as well (same things as last time), even though it will be a bit more work :)
I applied all patches now. You can try sound git tree either master or for-next branch.
thanks,
Takashi
