We want to use the higher level vdd on func here. Not a big deal yet (we'd just get the warn when things go awry) but when the locking gets fixed this becomes more important. Signed-off-by:

Passing the port as a parameter to PANEL_PORT_SELECT_VLV results in neater code. Sadly the PCH port select bits aren't suitable for the same treatment and the resulting macro would be much uglier, so leave those defines as is. Signed-off-by:

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!). Based on earlier patches by Jesse Barnes. v2: Remove Jesse's patch Reported-by:

Chris has decided that enough is enough. It's time to fixup dev Vs dev_priv. This is a modest contribution to the crusade. v2: Still use INTEL_INFO(), for the (mythical!) case we want to hardcode the info struct with defines (Chris) Rename the macro argument from 'dev' to 'dev_priv' (Jani) v3: Use names unlikely to be used as macro arguments (Chris) Suggested-by: -

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:

Jani Nikula authored
Make backlight class sysfs bl_power a sub-state of backlight enabled, if a backlight power connector callback is defined. It's up to the connector callback to handle the sub-state, typically in a way that respects panel power sequencing. v2: Post the version that does not oops. *facepalm*. Signed-off-by:

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.

Changes since v1: - Kill the sw interrupt dance, add and use radeon_irq_kms_sw_irq_get_delayed instead. - Change custom wait function, lockdep complained about it. Holding exclusive_lock in the wait function might cause deadlocks. Instead do all the processing in .enable_signaling, and wait on the global fence_queue to pick up gpu resets. - Process all fences in radeon_gpu_reset after reset to close a race with the trylock in enable_signaling. Changes since v2: - Small changes to work with the rewritten lockup recovery patches. Changes since v3: - Call radeon_fence_schedule_check when exclusive_lock cannot be acquired to always cause a wake up. - Reset irqs from hangup check. - Drop reading seqno in the callback, use cached value. - Fix indentation in radeon_fence_default_wait - Add a radeon_test_signaled function, drop a few test_bit calls. - Make to_radeon_fence global.
