Instead of going through hoops, just put the driver author directly as DRM_AUTHOR() argument. This will also make it consistent when we add Intel to the list. Signed-off-by:

Fix assert_panel_unlocked for vlv/chv, and improve it a bit for non-LVDS. Also don't pretend it works for DDI. There's still work to do to get this right for eDP on PCH platforms, but this is a start. v2: WARN_ON(HAS_DDI) Reviewed-by:

The patch introduces fixes for the debugfs attributes emitted by the i915 driver for GEN8. Currently, it is not emitting the correct attributes which include the status of RC6 states. Change-Id: Ib2068a0cac9a5wq3f228e547fa1a097ad369d242df Signed-off-by:

On BDW we're seeing a problem that after we runtime resume, the outputs connected to DDI C are not detected: they don't appear in the SDEISR register and GMBUS transactions don't work. They stop working at the moment we call intel_opregion_notify_adapter() during runtime suspend, but they don't go back to work when we call the same function during runtime resume. They only work after we do a modeset and call intel_opregion_notify_encoder(), but this point is already too late. While debugging, I tried to pass PCI_D3hot which is the value that matches the spec, and it seems to have solved the problem. I couldn't find any explanation of why this solves the problem, but there's also no documented explanation - besides our code and git log - of why Haswell should use PCI_D1, so keep this for now in order to keep BDW runtime PM working. Also add a comment to point the fact that there's no spec documenting all the weirdness involved here.

These two functions make no sense in an Logical Ring Context & Execlists world. v2: We got rid of lrc_enabled and centralized everything in the sanitized i915.enable_execlists instead. Signed-off-by:
Oscar Mateo <oscar.mateo@intel.com> v3: Rebased. Corrected a typo in comment for i915_switch_context and added a comment that it should not be called in execlist mode. Added WARN_ON if i915_switch_context is called in execlist mode. Moved check for execlist mode out of i915_switch_context and into callers. Added comment in context_reset explaining why nothing is done in execlist mode. Signed-off-by:

A pending commit removes synchronous mode from switch_mm. This breaks execlists because switch_mm will always try to write to the legacy ring buffer. Return immediately from i915_ppgtt_init_gw in execlists mode. No longer check for execlists mode in gen8_ppgtt_enable() because this will no longer be called in execlists mode. Signed-off-by:

Unfortunately, the gem_obj/vma relationship is not symmetrical; a gem_obj can look up for the same vma more than once (where the ppgtt refcount is incremented), but will free the vma only once (i915_gem_free_object). This difference in refcount get/put means that the ppgtt is not removed after the context and vma are destroyed, because sometimes the refcount will never go back to zero. v2: Just move the ppgtt refcount into vma_create.

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 that tries to enable a connector (disabling is easy!).

Chris has decided that enough is enough. It's time to fixup dev Vs dev_priv.

Since the ringbuffer does not belong per engine anymore, we have to make sure that we are always recording the correct ringbuffer. TODO: This is only a small fix to keep basic error capture working, but we need to add more information for it to be useful (e.g. dump the context being executed). v2: Reorder how the ringbuffer is chosen to clarify the change and rename the variable, both changes suggested by Chris Wilson. Also, add the TODO comment to the code, as suggested by Daniel. Signed-off-by:

For cleanliness, i915_error_object_create() was written to handle the NULL pointer in a central location. The macro that wrapped it and passed it a num_pages to use, was not safe. As we now never limit the num_pages to use (we did so at one point to only capture the first page of the context), we can remove the redundant macro and be NULL safe again. Signed-off-by:

For stolen pages, since it is verboten to access them directly on many architectures, we have to read them through the GTT aperture. If they are not accessible through the aperture, then we have to abort.

Make backlight class sysfs brightness 0 value switch off the backlight for connectors that have the backlight_power callback defined. For eDP, this has the similar caveats regarding power savings as bl_power as only the power sequencer backlight control is switched off. Signed-off-by:

Jani Nikula authored
This lets the userspace switch off the backlight using the backlight class sysfs bl_power file. The switch is done using the power sequencer; the backlight PWM, and everything else, remains enabled. The display backlight won't draw power, but for maximum power savings the encoder needs to be switched off. Signed-off-by:

Make backlight class sysfs bl_power a sub-state of backlight enabled, if a backlight power connector callback is defined.

Primary planes support 180 degree rotation. Expose the feature through rotation drm property. v2: Calculating linear/tiled offsets based on pipe source width and height. Added 180 degree rotation support in ironlake_update_plane. v3: Checking if CRTC is active before issueing update_plane. Added wait for vblank to make sure we dont overtake page flips. Disabling FBC since it does not work with rotated planes. v4: Updated rotation checks for pending flips, fbc disable. Creating rotation property only for Gen4 onwards. Property resetting as part of lastclose. v5: Resetting property in i915_driver_lastclose properly for planes and crtcs. Fixed linear offset calculation that was off by 1 w.r.t width in i9xx_update_plane and ironlake_update_plane. Removed tab based indentation and unnecessary braces in intel_crtc_set_property and intel_update_fbc. FBC and flip related checks should be done only for valid crtcs. v6: Minor nits in FBC disable checks for comments in intel_crtc_set_property and positioning the disable code in intel_update_fbc. v7: In case rotation property on inactive crtc is updated, we return successfully printing debug log as crtc is inactive and only property change is preserved. v8: update_plane is changed to update_primary_plane, crtc->fb is changed to crtc->primary->fb and return value of update_primary_plane is ignored. v9: added rotation property to primary plane instead of crtc. Removing reset of rotation property from lastclose. rotation_property is moved to drm_mode_config, so drm layer will take care of resetting. Adding updation of fbc when rotation is set to 0. Allowing rotation only if value is different than old one. v10: Calling intel_primary_plane_setplane instead of update_primary_plane in set_property(Daniel). v11: Using same set_property function for both primary and sprite, Adding primary plane specific code in the same function (Matt). v12: Removing disabling/ enabling of fbc from set_property because it is done from intel_pipe_set_base. Other formatting v13: we need to call disable_fbc before changing the rotation to 180, disable_fbc from intel_pipe_set_base gets called very late, that will be used to re-enable fbc if rotation is set to 0 (Ville).

This patch is to address Daniels concerns over different code during reset: http://lists.freedesktop.org/archives/intel-gfx/2014-June/047758.html "The reason for aiming as hard as possible to use the exact same code for driver load, gpu reset and runtime pm/system resume is that we've simply seen too many bugs due to slight variations and unintended omissions." Tested using igt drv_hangman. V2: Cleaner way of preventing check_wedge returning -EAGAIN V3: Clean the last_context during reset, to ensure do_switch() does the MI_SET_CONTEXT. As per review.
