Clean build probably needed since this touches a core header file. ioport_array_finder is a new device finder template for finding, unsurprisingly, an array of ioports. It is mainly intended to help handle multiplexed ioports without runtime tagmap lookups in a more elegant way than was previously possible. It is similar in principle to shared_ptr_array_finder; however, rather than passing a single tag that gets automatically decorated with numeric suffixes, you need to pass an array of tags (this is so ioports can continue to have human-meaningful tags rather than the tags being forced by how the hardware multiplexing happens to work). Because C++ doesn't have array literals, and because most driver state class constructors are defined in header files, the semantics are a little different from other device finders (and possibly awkward/suboptimal, this is the best I could think of). You have to declare the array of tags as a static class member and define it somewhere in a source file (defining it near the function that actually reads the multiplexed ports seems like the most logical place to me). Updated bladestl.c to use ioport_array_finder; will wait for Micko to pass judgement on the semantics before updating more drivers. |
