I tried compiling out fbcon and it does change things: 1. DMC loaded, idle system, no display, fbcon: PKG is in PC2 2. DMC loaded, idle system, no display, no fbcon: PKG is in PC7 Continuing with no fbcon and trying the HDMI force on - this now does not restore the performance to normal. And the i915_dmc_info "DC3 -> DC5" counter is still increasing rapidly as in the case with DMC, fbcon and no displays. Without DMC and no fbcon performance is good.
