* | drm/i915: Fix not checking cursor and object sizesGustavo Padovan2014-10-24

* | drm/i915: move check of intel_crtc_cursor_set_obj() outGustavo Padovan2014-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move check inside intel_crtc_cursor_set_obj() to intel_check_cursor_plane(), we only use it there so move them out to make the merge of intel_crtc_cursor_set_obj() into intel_check_cursor_plane() easier.

| * drm/i915: Don't trust the DP_DETECT bit for eDP ports on CHVVille Syrjälä2014-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On CHV the display DDC pins may be muxed to an alternate function if there's no need for DDC on a specific port, which is the case for eDP ports since there's no way to plug in a DP++ HDMI dongle. This causes problems when trying to determine if the port is present since the the DP_DETECTED bit is the latched state of the DDC SDA pin at boot. If the DDC pins are muxed to an alternate function the bit may indicate that the port isn't present. To work around this look at the VBT as well as the DP_DETECTED bit to determine if we should attempt registering an eDP port. Do this only for ports B and C since port D doesn't support eDP (no PPS/BLC). In theory someone could also wire up a normal DP port w/o DDC lines. That would just mean that simple DP++ HDMI dongles wouldn't work on such a port. With this change we would still fail to register such DP ports. But let's hope no one wires their board in such a way, and if they do we can extend the VBT checks to cover normal DP ports as well.

Also ditch the assignment in intel_pm_setup, that's not redundant since we do the assignement now while setting up interrupts.

The _irqsave version really should only be used if the calling context is unknown and there's a good reason to call a function from all kinds of places. This is the first step whice replaces all occurances of _irqsave in process context with the simpler irq disable/enable variants. We don't have any funky spinlock nesting going on, especially since the event_lock is the outermost of the irq/vblank related spinlocks.

Move the drm_vblank_{on,off}() calls back out from intel_crtc_{enable,disable}_planes() so that all of these vblank waits return to proper operation. Also move the cxsr wait a bit earlier so that we can keep the encoder disable after we've turned off vblanks. Moving stuff out from the plane enable/disable functions seems preferrable to moving the workaround stuff in since the workarounds are required only on specific platforms.

| * drm/i915: Check for a stalled page flip after each vblankChris Wilson2014-09-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Long ago, back in the racy haydays of 915gm interrupt handling, page flips would occasionally go astray and leave the hardware stuck, and the display not updating. This annoyed people who relied on their systems being able to display continuously updating information 24/7, and so some code to detect when the driver missed the page flip completion signal was added. Until recently, it was presumed that the interrupt handling was now flawless, but once again Simon Farnsworth has found a system whose display will stall. Reinstate the pageflip stall detection, which works by checking to see if the hardware has been updated to the new framebuffer address following each vblank. If the hardware is scanning out from the new framebuffer, but we still think the flip is pending, then we kick our driver into submision.

| * drm/i915: Add pipe B force quirk for 830MVille Syrjälä2014-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 830M has problems when some of the pipes are disabled. Namely if a plane, DVO port etc. is currently assigned to a disabled pipe, it can't moved to the other pipe until the current pipe is also enabled. To keep things simple just leave both pipes running all the time. Ideally I think should turn the pipes off if neither is active, and when either becomes active we enable both. But that would reuquire proper atomic modeset support, and probably a bit of extra care in the order things get enabled. v2: Reorder wrt. double wide handling changes Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Tested-by: Thomas Richter <richter@rus.uni-stuttgart.de> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 830 really does want the pipe A quirk. The planes and ports don't react to any register writes unless the pipe currently attached to them is running, so it's impossible to move them to the other pipe unless both pipes are running. Also it's documented that the DPLL must be enabled on both pipes whenever it's needed. This reverts commit ac6696d3236bd61503f89a1a99680fd7894d5d53.
