This commit applies the transition from the "Input" session to the "Event" session to the event-filtering mechansim. The functionality of the input_filter is now provided by the event_filter. The event filter requests only one "Event" session as destination for the filter result, which is usually routed to the nitpicker GUI server. It provides an "Event" service to which any number of event sources can connect. The configuration of the filter chain remains almost the same. Only the declaration of the <input> nodes is no longer needed. Instead, the configuration must specify <policy> nodes, which define the mapping of "Event" clients (event sources) to the inputs used in the filter chain. The patch adjusts all uses of the nitpicker GUI server accordingly such that the event filter reports events to nitpicker's event service instead of having nitpicker request an "Input" session. This dissolves the dependency of nitpicker from input drivers. Issue #3827
This directory is a source-code repository containing Genode-specific services and applications. In contrast to the components that come with the 'os' repository, programs contained in 'gems' are able to leverage the functionalities provided by higher-level repositories such as 'libports'. To use the 'gems' repository, make sure to also add those repositories to your build configuraion.
