PFW: Parameter adaptation (platform interface)
BZ: 15069 Adaptation nodes have been added to integer parameter types in the structural description. They all convert values between a platform value and the actual parameter value. When a conversion node affects the definition of an integer type parameter, its interface type becomes "double" (instead of integer). For now only linear adaptation type is supported. Linear adaptation: ================= Linear adaptation nodes consists of the following attributes: - slope numerator (double, default = 1) - slope denominator (double, defult = 1) - offset (signed integer, default = 0) Conversions from user (platform) values to blackboard are done the follwing way: blackboard_value = user_value * slope_numerator / slope_denominator + offset Change-Id: I00abe9ba5961d8e541b616225531bbc7c8b465b0 Signed-off-by: Patrick Benavoli <patrickx.benavoli@intel.com> Reviewed-on: http://android.intel.com:8080/25407 Reviewed-by: Barthes, FabienX <fabienx.barthes@intel.com> Tested-by: Barthes, FabienX <fabienx.barthes@intel.com> Reviewed-by: buildbot <buildbot@intel.com> Tested-by: buildbot <buildbot@intel.com>
