Hi, I have been working on adding DP compliance test request support in i915 driver. Unigraf DPR-120 is used as a DP Compliance reference sink device that generates a short pulse for the compliance test requests. In case of DP SST, these short pulses get handled in the i915 driver's short pulse handler (intel_dp_short_pulse). This has been successfully working to run the DP compliance tests for DP SST. The next step is to handle the DP compliance short pulses for DP MST. However in case of MST, it also recieves short pulses for the sideband traffic from the branch device. This gets handled in the DRM layer. Since the short pulses for MST get handled in drm layer, should the compliance short pulses for MST also be handled in DRM layer? In this case, DRM will read process the short pulse in DRM and call the Compliance test handler in i915 driver through a function pointer. Any thoughts on this implementation of DP compliance support for MST?
