From 9ed109a7b445e3f073d8ea72f888ec80c0532465 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 24 Apr 2014 23:54:52 +0200 Subject: [PATCH] drm/i915: Track has_audio in the pipe config Including state readout and cross-checking. This allows us to get rid of crtc->eld_vld on hsw+. It also means that fastboot will be unhappy if the BIOS hasn't set up the audio routing like we want it too. Wrt fastboot and external screens I see a few options: - Don't. - Try to fix up eld, infoframes and audio settings after the fact. But that means some pretty extensive reworking of our code which currently does all this while the pipe/port is still off. I won't bother with converting SDVO over to this because the audio support for SDVO is very lacking: - We don't update the eld. - We don't update the audio state on the sdvo encoder. - We don't check whether the platform can even feed audio to the sdvo encoder. I've converted hdmi, dp & ddi all in one go since ddi needs both hdmi and dp converted and so doing it step-by-step would have required a few intermediate hacks.
