This capability would benefit MSM as well. We're looking into a soc-specific implementation using Pat Pannuto's "pseudo" platform bus extensions (discussed here http://lkml.org/lkml/2010/8/10/389). After we have something working, I would be curious to see if some common functionality could be extracted into a more generic mechanism. - Bryan -- Sent by an employee of the Qualcomm Innovation Center, Inc.
