2020-09-15drm/i915: Reduce INTEL_DISPLAY_ENABLED to just treat outputs as disconnectedVille Syrjälä1-0/+6
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/dvo: Make .get_modes() return the number of modesVille Syrjälä1-6/+8
.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.

2020-04-03drm/i915: Pass atomic state to encoder hooksVille Syrjälä1-3/+6
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.

2020-01-27drm/i915/dvo: use intel_de_*() functions for register accessJani Nikula1-17/+17
The implicit "dev_priv" local variable use has been a long-standing pain point in the register access macros I915_READ(), I915_WRITE(), POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW(). Replace them with the corresponding new display engine register accessors intel_de_read(), intel_de_write(), intel_de_posting_read(), intel_de_read_fw(), and intel_de_write_fw(). No functional changes.

2020-01-13drm/i915: Pass intel_connector to intel_attached_*()Ville Syrjälä1-4/+4
Life is usually easier when we pass around intel_ types instead of drm_ types. In this case it might not be, but I think being consistent is a good thing anyway. Also some of this might get cleaned up a bit more later as we keep propagating the intel_ types further. @find@ identifier F =~ "^intel_attached_.*"; identifier C; @@ F(struct drm_connector *C) { ... } @@ identifier find.F; identifier find.C; @@ F( - struct drm_connector *C + struct intel_connector *connector ) { <... - C + &connector->base ...> } @@ identifier find.F; expression C; @@ - F(C) + F(to_intel_connector(C)) @@ expression C; @@ - to_intel_connector(&C->base) + C Signed-off-by: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Reviewed-by: Mika Kahola <[email protected]>
