linux's Issues

audio mediator enabling - multiple vm support

  1. add support for comp_id, pipeline_id, pcm_num dynamically assignment in audio mediator.
  2. add more locks to avoid the contest between operations in the VMs.
  3. add support of VM shut down and restart.

audio mediator enabling - new topology mode support

  1. create topology files -- 1 or 2 days
  • Vivian will help work out a prototype for vBE and vFE. Libin will refine the topology file.
  1. vFE supports new topology mode -- 1WW
  • Need add some new IPCs to send the vBE of some critical informations
  • TODO: figure out which changes should be done in vFE. (Mostly these changes are related to IPC)
  1. vBE supports new topology mode: --1.5WW
  • handle host widget
  • handle dai_drv, dai
  • handle dai_link/rtd/pcm/substream/spcm
  • handle widget connections by graph
  • handle stream operation, including open/hw_param/close
  • PM support?
  1. Load topology mode -- 2 days (low priority)
  • Load the topology file in SOS for both vFE and vBE. vBE will send the corresponding topology file to the vFE.
  1. debug -- 1.5WW
  • As this is a new mode which is never used before, let's say it will take 1.5WW to fix the potential issues.

audio mediator enabling

  1. new topology mode support -- 4WW
    see details in: #2

  2. multiple vm support -- 2WW
    see details in: #3

  3. record support -- 2WW
    see details in: #4

audio mediator enabling - record support

  1. add support in topology files
  • add support in vFE topology file
  • add support in vBE topology file
  1. add support for simultaneous multiple PCM support
  • Most work should already be done, need figure out the remain tasks, such as lock and etc.
