[alsa-devel] [PATCH 0/7] ALSA: hda: Enable HDAudio compress

[Cezary Rojewski <cezary.rojewski@intel.com>]

This set of patches provides new interfaces - page allocation - and
runtime flow adjustments - PM support - for compress operations.
For HDA part, work has been done to account for compress streams when
servicing IRQs, setting up BDLs and assigning DMAs.

End goal is to make room for one of DSP debug features: data probing.
It takes advantage of compress streams when extracting data from
running audio pipeline.

Initial review and development of probes can be found under:
https://github.com/thesofproject/linux/pull/1276

with this very set of patches being separated and reviewed on:
https://github.com/thesofproject/linux/pull/1571
