From b81dddb909b4fa4498d96b2bf7748ae1e86e5e67 Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Thu, 10 Sep 2020 19:42:56 +0300 Subject: drm/i915: Reduce INTEL_DISPLAY_ENABLED to just treat outputs as disconnected MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 Link: https://patchwork.freedesktop.org/patch/msgid/20200910164256.25983-1-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula --- drivers/gpu/drm/i915/display/intel_crt.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/gpu/drm/i915/display/intel_crt.c') diff --git a/drivers/gpu/drm/i915/display/intel_crt.c b/drivers/gpu/drm/i915/display/intel_crt.c index 5b4510ce5693..4934edd51cb0 100644 --- a/drivers/gpu/drm/i915/display/intel_crt.c +++ b/drivers/gpu/drm/i915/display/intel_crt.c @@ -833,6 +833,9 @@ intel_crt_detect(struct drm_connector *connector, connector->base.id, connector->name, force); + if (!INTEL_DISPLAY_ENABLED(dev_priv)) + return connector_status_disconnected; + if (dev_priv->params.load_detect_test) { wakeref = intel_display_power_get(dev_priv, intel_encoder->power_domain); -- cgit v1.2.3
