2020-09-15drm/i915: Reduce INTEL_DISPLAY_ENABLED to just treat outputs as disconnectedVille Syrjälä1-1/+5
Since the display hardware is all there even when INTEL_DISPLAY_ENABLED return false we have to be capable of shutting it down cleanly so as to not anger the hw. To that end let's reduce the effect of !INTEL_DISPLAY_ENABLE to just treating all outputs as disconnected. Should prevent anyone from automagically enabling any of them, while still allowing us to cleanly shut them down. v2: Put the check into the right place for CRT Signed-off-by: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Reviewed-by: Jani Nikula <[email protected]>

2020-07-09drm/i915/sdvo: Make .get_modes() return the number of modesVille Syrjälä1-23/+33
.get_modes() is supposed to return the number of modes added to the probed_modes list (not that anyone actually checks for anything except zero vs. not zero). Let's do that. Also switch over to using intel_connector_update_modes() instead of hand rolling it.

2020-07-09drm/i915/sdvo: Make SDVO deal with HDMI pixel repeatVille Syrjälä1-4/+23
With SDVO the pipe config pixel_multiplier only concerns itself with the data on the SDVO bus. Any HDMI specific pixel repeat must be handled by the SDVO device itself. To do that simply configure the SDVO pixel replication factor appropriately. We already set up the infoframe PRB values correctly via the infoframe helpers. There is no cap we can check for this. The spec says that 1X,2X,4X are mandatory, anything else is optional. 1X and 2X are all we need so we should be able to assume they work.

2020-07-09drm/i915/sdvo: Implement limited color range for SDVO HDMI properlyVille Syrjälä1-23/+39
The SDVO/HDMI port register limited color range bit can only be used with TMDS encoding and not SDVO encoding, ie. to be used only when using the port as a HDMI port as opposed to a SDVO port. The SDVO spec does have a note that some GMCHs might allow that, but gen4 bspec vehemently disagrees. I suppose on ILK+ it might work since the color range handling is on the CPU side rather than on the PCH side, so there is no clear linkage between the TMDS vs. SDVO encoding and color range. Alas, I have no hardware to test that theory. To implement limited color range support for SDVO->HDMI we need to ask the SDVO device to do the range compression. Do so, but first check if the device even supports the colorimetry selection.

2020-04-03drm/i915: Pass atomic state to encoder hooksVille Syrjälä1-6/+11
We're going to want access to the atomic state for iterating the slave crtcs when enabling the port sync master crtc. Pass the atomic state all the way down. The alternative would be yet another encoder hook which we'll have to call after all the normal modeset stuff is done. Not really a fan of yet another hook just for this. Note that during readout state sanitation we are now going to pass NULL as the atomic state since we don't have one. We need to change that and then we can also s/crtc_state/crtc/ and s/conn_state/conn/ for the encoder hooks as well.
