...n if nothing has changed Additionally, the code for handling DP that we have in nouveau is also quite unoptimized in general, doesn't use a lot of helpers that have been added since it was written, and is also missing quite a number of features: * Downstream port capability probing * Extended DPRX cap parsing * SINK_COUNT handling for hpd on dongles Luckily for us - all of these are implemented in i915 already. Since there's no reason for us to reinvent the wheel, and having more shared code is always nice, I decided to take the opportunity to extract the code for all of these features...
