This series proposes SW workarounds for Tegra194 HDA HW bugs. Following are the two issues seen:
- GCAP register does not reflect true capability. The actual number of SDO lines is "4", where as it reflects "2".
- With 4 SDO line configuration playback fails for, 44.1K/48K, 2-channel, 16-bps audio stream.
After fixing [1], issue [2] is uncovered. As per recommendation by Tegra HW team the workarounds are pushed.
Testing done
- Verify GCAP register after registering HDA sound card
- Verify audio playback for 44.1K/48K, 2-channel, 16-bps.
Sameer Pujar (3): ALSA: hda/tegra: correct number of SDO lines for Tegra194 ALSA: hda: add member to store ratio for stripe control ALSA: hda/tegra: workaround playback failure on Tegra194
Through a quick glance, all changes look good.
Is the device already in market, i.e. it had hit users? If yes, I'm going to merge for 5.7, otherwise for 5.8.
Yes the device is in the market. But has not been reported by end users. During internal resting this has been discovered. I am fine with merging this to 5.8.
Thanks, Sameer.
thanks,
