From b708a1d5ea7880b399dbd45cacafff6ae8d73171 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Mon, 11 Jun 2012 14:39:56 -0400 Subject: [PATCH] drm/i915: don't enumerate HDMID if an eDP panel is already active on the port This prevents the HDMI detect functions from poking at an eDP connected panel, which can lead to trouble. [danvet: Note that we have some other reports of DP vs. HDMI fighting, but the general case is a much bigger fish to fry.] References: https://bugs.freedesktop.org/show_bug.cgi?id=42278 Signed-off-by: Jesse Barnes Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_display.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index e0aa064def31..a7c727d0c105 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -6558,7 +6558,7 @@ static void intel_setup_outputs(struct drm_device *dev) if (I915_READ(HDMIC) & PORT_DETECTED) intel_hdmi_init(dev, HDMIC); - if (I915_READ(HDMID) & PORT_DETECTED) + if (!dpd_is_edp && I915_READ(HDMID) & PORT_DETECTED) intel_hdmi_init(dev, HDMID); if (I915_READ(PCH_DP_C) & DP_DETECTED) -- GitLab
