From ef34ab894e54c97850296b5f8268004bf6788c74 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Thu, 20 Feb 2014 12:28:07 -0800 Subject: [PATCH] drm/i915: honor forced connector modes v2 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In the move over to use BIOS connector configs, we lost the ability to force a specific set of connectors on or off. Try to remedy that by dropping back to the old behavior if we detect a hard coded connector config. v2: don't deref connector state for disabled connectors (Jesse) Reported-by: Ville Syrjälä Signed-off-by: Jesse Barnes Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_fbdev.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_fbdev.c b/drivers/gpu/drm/i915/intel_fbdev.c index 19be4bfbcc59..4e4b461e0a70 100644 --- a/drivers/gpu/drm/i915/intel_fbdev.c +++ b/drivers/gpu/drm/i915/intel_fbdev.c @@ -291,6 +291,24 @@ static bool intel_fb_initial_config(struct drm_fb_helper *fb_helper, bool *save_enabled; bool any_enabled = false; + /* + * If the user specified any force options, just bail here + * and use that config. + */ + for (i = 0; i < fb_helper->connector_count; i++) { + struct drm_fb_helper_connector *fb_conn; + struct drm_connector *connector; + + fb_conn = fb_helper->connector_info[i]; + connector = fb_conn->connector; + + if (!enabled[i]) + continue; + + if (connector->force != DRM_FORCE_UNSPECIFIED) + return false; + } + save_enabled = kcalloc(dev->mode_config.num_connector, sizeof(bool), GFP_KERNEL); if (!save_enabled) -- 2.30.2
