Adds a method to select a suitable sink connected to a given source. In cases where no sink is defined, the coresight_find_default_sink routine can search from a given source, through the child connections until a suitable sink is found. The suitability is defined in by the sink coresight_dev_subtype on the CoreSight device, and the distance from the source by counting connections. Higher value subtype is preferred - where these are equal, shorter distance from source is used as a tie-break. This allows for default sink to be discovered were none is specified (e.g. perf command line) Signed-off-by: Mike Leach <mike.leach@linaro.org> Suggested-by: Suzuki K Poulose <suzuki.poulose@arm.com> Reviewed-by: Leo Yan <leo.yan@linaro.org> Reviewed-by: Suzuki K Poulose <suzuki.poulose@arm.com> Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org> Link: https://lore.kernel.org/r/20200716175746.3338735-15-mathieu.poirier@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
