When no console framebuffer is enabled, the default plane state is defined by plane reset function. If driver uses generic helper, then rotation property is set to zero. This is not a valid value for that enum. This patch sets default rotation value to DRM_ROTATE_0.

One of the two local variables old_crtc_state is redundantly defined in the function disable_outputs(). It has only a scope partway through the block for_each_connector_in_state. So, let's remove it and use the one which has the scope within the function disable_outputs().

Maxime Ripard authored
The drm_fbdev_cma_init function always calls the drm_helper_disable_unused_functions. Since it's part of the usual probe process, all the drivers using that helper will end up having their encoder and CRTC disable functions called at probe if their device has not been reported as enabled. This could be fixed by reading out from the registers the current state of the device if it is enabled, but even that will not handle the case where the device is actually disabled. Moreover, the drivers using the atomic modesetting expect that their enable and disable callback to be called when the device is already enabled or disabled (respectively). We can however fix this issue by moving the call to drm_helper_disable_unused_functions out of drm_fbdev_cma_init and make the drivers needing it (all the drivers calling drm_fbdev_cma_init and not using the atomic modesetting) explicitly call it.

When the framebuffer is a vmwgfx dma buffer and a proxy surface is created, the vmw_kms_update_proxy() function requires that the proxy surface width and the framebuffer pitch are compatible, otherwise display corruption occurs as seen in gnome-shell/native with software 3D. Since the framebuffer pitch is determined by user-space, allocate a proxy surface the width of which is based on the framebuffer pitch rather than on the framebuffer width.

An encoder is associated with a connector by the DRM core as a result of setting up a configuration. Drivers using the atomic or legacy helpers should never set up this link, even if it is a static one. While at it, try to catch this kind of error in the future by adding a WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't cover all the cases, since drivers could set this up after attaching. Drivers that use the atomic helpers will get a warning later on, though, so hopefully the two combined cover enough to help people avoid this in the future.

This fixes reprobing of display connectors on resume. After some talking with danvet on IRC, I learned that calling drm_helper_hpd_irq_event() does actually trigger a full reprobe of each connector's status. It turns out this is the actual reason reprobing on resume hasn't been working (this was observed on a T440s): - We call hpd_init() - We check each connector for a couple of things before marking connector->polled with DRM_CONNECTOR_POLL_HPD, one of which is an active encoder. Of course, a disconnected port won't have an active encoder, so we don't add the flag to any of the connectors. - We call drm_helper_hpd_irq_event() - drm_helper_irq_event() checks each connector for the DRM_CONNECTOR_POLL_HPD flag. The only one that has it is eDP-1, so we skip reprobing each connector except that one. In addition, we also now avoid setting connector->polled to DRM_CONNECTOR_POLL_HPD for MST connectors, since their reprobing is handled by the mst helpers. This is probably what was originally intended to happen here. Changes since V1: * Use the explanation of the issue as the commit message instead * Change the title of the commit, since this does more then just stop a check for an encoder now * Add "Fixes" line for the patch that introduced this regression * Don't enable DRM_CONNECTOR_POLL_HPD for mst connectors Changes since V2: * Put patch changelog above Signed-off-by * Follow Daniel Vetter's suggestion for making the code here a bit more legible Fixes: 0e32b39c ("drm/i915: add DP 1.2 MST support (v0.7)") Cc: stable@vger.kernel.org Signed-off-by: Lyude <cpaul@redhat.com> Link: http://patchwork.freedesktop.org/patch/msgid/1452181408-14777-1-git-send-email-cpaul@redhat.comSigned-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 07c51913) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
