drm/tegra: Changes for v3.10-rc1 The bulk of this pull-request is the host1x series that has been in the works for a few months. The current implementation looks good and has been tested by several independent parties. So far no issues have been found. To be on the safe side, the new Tegra-specific DRM IOCTLs depend on staging in order to give some amount of flexibility to change them just in case. The plan is to remove that dependency once more userspace exists to verify the adequacy of the IOCTLs. Currently only the 2D engine is supported, but patches are in the works to enable 3D support on top of this framework as well. Various bits of open-source userspace exist to test the 2D and 3D support[0]. This is still a bit immature but it allows to verify that the kernel interfaces work properly. To round things off there are two smaller cleanup patches, one of them adding a new pixel format and the other removing a redundent Kconfig dependency.

While migrating to common clock framework (CCF), I found that the FIMD clocks were pulled down by the CCF. If CCF finds any clock(s) which has NOT been claimed by any of the drivers, then such clock(s) are PULLed low by CCF. Calling clk_prepare() for FIMD clocks fixes the issue. This patch also replaces clk_disable() with clk_unprepare() during exit, since clk_prepare() is called in fimd_probe(). Signed-off-by:

For a bunch of reason we need to more accurately track this: - hw pipe state readout for Haswell needs the cpu transcoder. - We need to know the right cpu transcoder in a bunch of places in ->disable and other modeset callbacks. In the future we need to add hw state readout&check support, too. But to avoid ugly merge conflicts do the rote sed job now without any functional changes. v2: Preserve the cpu_transcoder value when overwriting crtc->config. Reported by Paulo.

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. Noise on the interrupt line renders the hotplug interrupt useless: each hotplug event causes the devices to be rescanned which will will only increase the system load. Thus disable the hotplug interrupts and fall back to periodic device polling. v2: Fixed cleanup typo. v3: Fixed format issues, clarified a variable name, changed pr_warn() to DRM_INFO() as suggested by Jani Nikula <jani.nikula@linux.intel.com>.

To disable previously enabled HPD IRQs we need to reset them and set the enabled ones individually. Signed-off-by:

Egbert Eich authored
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. Signed-off-by:

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.
