Hi Jerome Thank you for your reply > However, I'm a bit confused. If it is handled automatically by the CPUs > and Codecs settings, does it mean dpcm_playback/capture flags are > no-ops from now on ? Yes. dpcm_playback/capture flag itself will be exist for a while, but it will be removed soon (v6.11 ? v6.12 ? not yet fixed). Some driver might is using dpcm_xxx flag as limitation of direction. For example HW can use both playback/capture, but driver want to use playback only, in this case, driver might have dpcm_playback flag only. In this case, driver authoer need to update to use playback_only flag instead. [1/3] patch will indicate warning about it, for a while. > Should I update my card drivers to ditch those flags completely ? If the driver is using dpcm_xxx flag as limitation of direction, driver author need to update to use xxx_only flag. If the driver have no such flag miss, I will remove all dpcm_xxx flags when end of its support. Of course we can avoid extra problem if each driver author remove/update it by themself, instead of me ;P > May I still disable a direction on a link from the card driver, like in > the case I described above, when a TDM link has no slots for a direction ? For example, in case of CPU can handle both playback/capture, and Codec handles playback only, it will be playback only automatically, no Card settings is needed. If both CPU/Codec can handle playback/capture, but you want to enable playback only, you can use playback_only flag. Is it help you ? Thank you for your help !!
