Re: [Sound-open-firmware] [RFC PATCH 1/6] host: add host testbench common source and header files

On Thu, 2018-05-31 at 19:29 -0700, Ranjani Sridharan wrote:

This patch adds the common header and source files required for all component testbench. These files include routines for parsing topology files, initializing sof ipc, scheduler, memory allocation and pipeline structures. It also provides simpler implementations for some of the SOF features such as tracing.
