From 4165791d29f64e01860a064f3c649447dbac41c3 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 22 Mar 2018 19:41:35 +0200 Subject: [PATCH] drm/i915: Make force_load_detect effective even w/ DMI quirks/hotplug MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When doing forced load detection testing we should totally ignore any hotplug status for the connector. This is mostly relevant for machines where we already ignore the hotplug status based on the DMI quirks. On other machines we would currently skip the force load detection tests on account of the connector already being connected. v2: Drop the other force_load_detect check since it's useless now (Maarten) Cc: Maarten Lankhorst Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20180322174135.5982-1-ville.syrjala@linux.intel.com Reviewed-by: Maarten Lankhorst --- drivers/gpu/drm/i915/intel_crt.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_crt.c b/drivers/gpu/drm/i915/intel_crt.c index c0a8805b277f..de0e22322c76 100644 --- a/drivers/gpu/drm/i915/intel_crt.c +++ b/drivers/gpu/drm/i915/intel_crt.c @@ -748,6 +748,11 @@ intel_crt_detect(struct drm_connector *connector, connector->base.id, connector->name, force); + if (i915_modparams.load_detect_test) { + intel_display_power_get(dev_priv, intel_encoder->power_domain); + goto load_detect; + } + /* Skip machines without VGA that falsely report hotplug events */ if (dmi_check_system(intel_spurious_crt_detect)) return connector_status_disconnected; @@ -776,11 +781,12 @@ intel_crt_detect(struct drm_connector *connector, * broken monitor (without edid) to work behind a broken kvm (that fails * to have the right resistors for HP detection) needs to fix this up. * For now just bail out. */ - if (I915_HAS_HOTPLUG(dev_priv) && !i915_modparams.load_detect_test) { + if (I915_HAS_HOTPLUG(dev_priv)) { status = connector_status_disconnected; goto out; } +load_detect: if (!force) { status = connector->status; goto out; -- 2.30.2
