2016-07-19drm/i915/vlv: Disable HPD in valleyview_crt_detect_hotplug()Lyude
One of the things preventing us from using polling is the fact that calling valleyview_crt_detect_hotplug() when there's a VGA cable connected results in sending another hotplug. With polling enabled when HPD is disabled, this results in a scenario like this: - We enable power wells and reset the ADPA - output_poll_exec does force probe on VGA, triggering a hpd - HPD handler waits for poll to unlock dev->mode_config.mutex - output_poll_exec shuts off the ADPA, unlocks dev->mode_config.mutex - HPD handler runs, resets ADPA and brings us back to the start This results in an endless irq storm getting sent from the ADPA whenever a VGA connector gets detected in the middle of polling. Somewhat based off of the "drm/i915: Disable CRT HPD around force trigger" patch Ville Syrjälä sent a while back Cc: stable@vger.kernel.org Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Lyude <cpaul@redhat.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit b236d7c8421969ac0693fc571e47ee5c2a62fb90)
2016-07-19drm/i915/vlv: Reset the ADPA in vlv_display_power_well_init()Lyude
While VGA hotplugging worked(ish) before, it looks like that was mainly because we'd unintentionally enable it in valleyview_crt_detect_hotplug() when we did a force trigger. This doesn't work reliably enough because whenever the display powerwell on vlv gets disabled, the values set in VLV_ADPA get cleared and consequently VGA hotplugging gets disabled. This causes bugs such as one we found on an Intel NUC, where doing the following sequence of hotplugs: - Disconnect all monitors - Connect VGA - Disconnect VGA - Connect HDMI Would result in VGA hotplugging becoming disabled, due to the powerwells getting toggled in the process of connecting HDMI. Changes since v3: - Expose intel_crt_reset() through intel_drv.h and call that in vlv_display_power_well_init() instead of encoder->base.funcs->reset(&encoder->base); Changes since v2: - Use intel_encoder structs instead of drm_encoder structs Changes since v1: - Instead of handling the register writes ourself, we just reuse intel_crt_detect() - Instead of resetting the ADPA during display IRQ installation, we now reset them in vlv_display_power_well_init() Cc: stable@vger.kernel.org Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Lyude <cpaul@redhat.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> [danvet: Rebase over dev_priv/drm_device embedding.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 9504a89247595b6c066c68aea0c34af1fc78d021)

2016-07-18drm/i915: Treat eDP as always connected, againVille Syrjälä
eDP should be treated as connected even if doesn't have an EDID. In that case we'll use the timings from the VBT. That used to be the case until commit f21a21983ef1 ("drm/i915: Splitting intel_dp_detect") broke things by considering even eDP disconnected if we fail to get an EDID for it. Fix things up again by treating eDP as always connected.

2016-07-14drm/i915: Ignore panel type from OpRegion on SKLVille Syrjälä
Dell XPS 13 9350 apparently doesn't like it when we use the panel type from OpRegion. The OpRegion panel type (0) tells us to use use low vswing for eDP, whereas the VBT panel type (2) tells us to use normal vswing. The problem is that low vswing results in some display flickers.

Prior to gen6 we didn't have per-ring IMR registers, which means that since commit 61ff75ac20ff ("drm/i915: Simplify enabling user-interrupts with L3-remapping") we're now masking off all interrupts when init_render_ring() gets called.

2016-07-14drm/i915/breadcrumbs: Queue hangcheck before sleepingChris Wilson
Never go to sleep waiting on the GPU without first ensuring that we will get woken up. We have a choice of queuing the hangcheck before every schedule() or the first time we wakeup. In order to simply accommodate both the signaler and the ordinary waiter, move the queuing to the common point of enabling the irq. We lose the paranoid safety of ensuring that the hangcheck is active before the sleep, but avoid code duplication (and redundant hangcheck queuing).

2016-07-08drm/i915: Fill unused GGTT with scratch pages for VT-dChris Wilson
One of the numerous VT-d workarounds we require is that the display hardware reads past the end of the buffer triggering VT-d faults. This is acknowledged in the code as being safe "since we fill the unused portions of the GGTT with the scratch page". Alas, that is no longer always true and so we trigger DMAR read faults. Skylake also requires another workaround to avoid mixing VT-d and unpopulated PTE, and so there we also need to ensure we fill unused entries with the scratch page.

2016-07-07drm/i915: Check for invalid cloning earlier during modesetVille Syrjälä
Move the encoder cloning check to happen earlier in the modeset. The main benefit will be that the debug output from a failed modeset will be less confusing as output_types can not indicate an invalid configuration during the later computation stages. For instance, what happened to me was kms_setmode was attempting one of its invalid cloning checks during which it asked for DP+VGA cloning on HSW. In this case the DP .compute_config() was executed after the FDI .compute_config() leaving the DP link clock (1.62 in this case) in port_clock, and then later the FDI BW computation tried to use that as the FDI link clock (which should always be 2.7). 1.62 x 2 wasn't enough for the mode it was trying to use, and so it ended up rejecting the modeset, not because of an invalid cloning configuration, but because of supposedly running out of FDI bandwidth. Took me a while to figure out what had actually happened.
