We disable hoptplug detection when we encounter a hotplug event storm. Still hotplug detection is required on some outputs (like Display Port). The interrupt storm may be only temporary (on certain Dell Laptops for instance it happens at certain charging states of the system). Thus we enable it after a certain grace period (2 minutes). Should the interrupt storm persist it will be detected immediately and it will be disabled again. v2: Reordered drm_i915_private: moved hotplug_reenable_timer to hpd state tracker. v3: Clarified loop start value, Removed superfluous test for Ivybridge and Haswell, Restructured loop to avoid deep nesting (all suggested by Ville Syrjälä) v4: Fixed two bugs pointed out by Jani Nikula.

This patch disables hotplug interrupts if an 'interrupt storm' has been detected.

When an encoder is shared on several connectors there is only one hotplug line, thus this line needs to be shared among these connectors. If HPD detect only works reliably on a subset of those connectors, we want to poll the others. Thus we need to make sure that storm detection doesn't mess up the settings for those connectors. Therefore we store the settings in the intel_connector struct and restore them from there. If nothing is set but the encoder has a hpd_pin set we assume this connector is hotplug capable. On init/reset we make sure the polled state of the connectors is (re)set to the default value, the HPD interrupts are marked enabled.

Add a hotplug IRQ storm detection (triggered when a hotplug interrupt fires more than 5 times / sec). Rationale: Despite of the many attempts to fix the problem with noisy hotplug interrupt lines we are still seeing systems which have issues: Once cause of noise seems to be bad routing of the hotplug line on the board: cross talk from other signals seems to cause erronous hotplug interrupts. This has been documented as an erratum for the the i945GM chipset and thus hotplug support was disabled for this chipset model but others seem to have this problem, too. We have seen this issue on a G35 motherboard for example: Even different motherboards of the same model seem to behave differently: while some only see only around 10-100 interrupts/s others seem to see 5k or more. We've also observed a dependency on the selected video mode. Also on certain laptops interrupt noise seems to occur duing battery charging when the battery is at a certain charge levels. Thus we add a simple algorithm here that detects an 'interrupt storm' condition. v2: Fixed comment. v3: Reordered drm_i915_private: moved hpd state tracking to hotplug work stuff. v4: Followed by Jesse Barnes to use a time_..() macro. v5: Fixed coding style as suggested by Jani Nikula.

Yet again our current confusion between doing the modeset globally, but only having the new parameters for one crtc at a time. So that intel_set_mode essentially already does a global modeset: intel_modeset_affected_pipes compares the current state with where we want to go to (which is carefully set up by intel_crtc_set_config) and then goes through the modeset sequence for any crtc which needs updating. Now the issue is that the actual interface with the remaining code still only works on one crtc, and so we only pass in one fb and one mode. In intel_set_mode we also only compute one intel_crtc_config (which should be the one for the crtc we're doing a modeset on). The reason for that mismatch is twofold: - We want to eventually do all modeset as global state changes, so it's just infrastructure prep. - But even the old semantics can change more than one crtc when you e.g. move a connector from crtc A to crtc B, then both crtc A and B need to be updated. Usually that means one pipe is disabled and the other enabled. This is also the reason why the hack doesn't touch the disable_pipes mask. Now hilarity ensued in our kms config restore paths when we actually try to do a modeset on all crtcs: If the first crtc should be off and the second should be on, then the call on the first crtc will notice that the 2nd one should be switched on and so tries to compute the pipe_config. But due to a lack of passed-in fb (crtc 1 should be off after all) it only results in tears. This case is ridiculously easy to hit on gen2/3 where the lvds output is restricted to pipe B. Note that before the pipe_config bpp rework gen2/3 didn't care really about the fb->depth, so this is a regression brought to light with commit 4e53c2e0 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Mar 27 00:44:58 2013 +0100 drm/i915: precompute pipe bpp before touching the hw But apparently Ajax also managed to blow up pch platforms, probably with some randomized configs, and pch platforms trip up over the lack of an fb even in the old code.

Backlight cleanup in the eDP connector destroy callback caused the backlight device to be removed on some systems that first initialized LVDS and then attempted to initialize eDP. Prevent multiple backlight initializations, and ensure backlight cleanup is only done once by moving it to modeset cleanup. A small wrinkle is the introduced asymmetry in backlight setup/cleanup. This could be solved by adding refcounting, but it seems overkill considering that there should only ever be one backlight device.

Increase the number of fence registers to 32 on IVB/HSW. VLV however only has 16 fence registers according to the docs. Increasing the number of fences was attempted before [1], but there was some uncertainty about the maximum CPU fence number for FBC. Since then BSpec has been updated to state that there are in fact 32 fence registers, and the CPU fence number field in the SNB_DPFC_CTL_SA register is 5 bits, and the CPU fence number field in the ILK_DPFC_CONTROL register must be zero.
