Fwiw we do have some unnecessary complexity in our hw_params() and hw_free() calls in order to support OSS emulation. i.e. hw_params() can be called several times for each substream by OSS emulation with different audio parameters each time (hence the need to always free and re-config resources). This is not needed for native alsa. Mark and I have just agreed we will accept patches that remove this sort of complexity and hence OSS emulation support. OSS is being dropped by distro's anyway now and we haven't been testing OSS emu on new ASoC drivers for a while either..... So don't feel obliged to support OSS emulation in your fix. > > I know there are some pxa-ssp related things pending which will also > > cause merge conflicts - which tree should thing apply to currently? > The major work Mark mentioned is the multi-codec + multi-platform (Audio Engine) support. Mark and I are just finalising the API changes and there is some a development branch here :- http://git.kernel.org/?p=linux/kernel/git/lrg/asoc-2.6.git;a=shortlog;h=refs/heads/topic/multi-codec The API move things closer the the driver model and are being aimed at 2.6.35.
