2016-03-17drm/i915: Split out load time interface registrationImre Deak
According to the new init phases scheme we should register the device making it available via some kernel internal or user space interface as the last step in the init sequence, so move the corresponding code to a separate function. Also add a TODO comment about code that still needs to be moved around to one of the init phases functions depending on what the role and effect of that code is. No functional change, except for the reordering of the unload time unregistration steps of sysfs wrt. acpi and opregion. Suggested by Chris. v3: - rename i915_driver_init_register to i915_driver_init_frameworks (Chris) - rename i915_driver_init_frameworks to i915_driver_register (Daniel) CC: Chris Wilson <chris@chris-wilson.co.uk> CC: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/1458128348-15730-18-git-send-email-imre.deak@intel.com
2016-03-17drm/i915: Split out load time HW initializationImre Deak
According to the new init phases scheme we should have a definite step in the init sequence where we setup things requiring accessing the device, so move the corresponding code to separate function. The steps in this init phase should avoid exposing the driver via some interface, which is done in the last registration init phase. This changae also has the benefit of making the error path cleaner both in the new function and i915_driver_load()/unload(). No functional change. Suggested by Chris.

2016-03-17drm/i915: Split out load time early initializationImre Deak
According to the new init phases scheme we should initialize "SW-only" state not requiring accessing the device as the very first step, so that the reasoning about dependencies of later steps becomes easier. So move these init steps into a separate function. This also has the benefit of making the error path cleaner both in the new function and int i915_driver_load()/unload(). No functional change.

In full gpu reset we prime all engines and reset domains corresponding to each engine. Per engine reset is just a special case of this process wherein only a single engine is reset. This change is aimed to modify relevant functions to achieve this. There are some other steps we carry out in case of engine reset which are addressed in later patches. Reset func now accepts a mask of all engines that need to be reset. Where per engine resets are supported, error handler populates the mask accordingly otherwise all engines are specified. v2: ALL_ENGINES mask fixup, better for_each_ring_masked (Chris) v3: Whitespace fixes (Chris) v4: Rebase due to s/ring/engine Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Signed-off-by: Arun Siluvery <arun.siluvery@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1458143640-20563-1-git-send-email-mika.kuoppala@intel.com

2016-03-17drm/i915: Fix race condition in intel_dp_destroy_mst_connector()Lyude
After unplugging a DP MST display from the system, we have to go through and destroy all of the DRM connectors associated with it since none of them are valid anymore. Unfortunately, intel_dp_destroy_mst_connector() doesn't do a good enough job of ensuring that throughout the destruction process that no modesettings can be done with the connectors. As it is right now, intel_dp_destroy_mst_connector() works like this: * Take all modeset locks * Clear the configuration of the crtc on the connector, if there is one * Drop all modeset locks, this is required because of circular dependency issues that arise with trying to remove the connector from sysfs with modeset locks held * Unregister the connector * Take all modeset locks, again * Do the rest of the required cleaning for destroying the connector * Finally drop all modeset locks for good This only works sometimes. During the destruction process, it's very possible that a userspace application will attempt to do a modesetting using the connector. When we drop the modeset locks, an ioctl handler such as drm_mode_setcrtc has the oppurtunity to take all of the modeset locks from us. When this happens, one thing leads to another and eventually we end up committing a mode with the non-existent connector: [drm:intel_dp_link_training_clock_recovery [i915]] *ERROR* failed to enable link training [drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x7cf0001f [drm:intel_dp_start_link_train [i915]] *ERROR* failed to start channel equalization [drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x7cf0001f [drm:intel_mst_pre_enable_dp [i915]] *ERROR* failed to allocate vcpi And in some cases, such as with the T460s using an MST dock, this results in breaking modesetting and/or panicking the system. To work around this, we now unregister the connector at the very beginning of intel_dp_destroy_mst_connector(), grab all the modesetting locks, and then hold them until we finish the rest of the function.

2016-03-16drm/i915/bios: drop has_mipi in favor of intel_bios_is_dsi_presentJani Nikula
Favor a single point of truth instead of duplicating the information. The change also filters out unsupported DSI ports at this stage, accepting only ports A and C, instead of waiting until the port checks.

Use the connector type instead of VBT directly to decide which backlight mechanism to use on VLV/CHV. (Indirectly, this is the same thing, but hides the VBT use.)
