2016-09-28drm/udl: fix line iterator in damage handlingDavid Herrmann
The udl damage handler is supposed to render 'height' lines, but its iterator has an obvious typo that makes it miss most lines if the rectangle does not cover 0/0. Fix the damage handler to correctly render all lines.

2016-09-19drm: Only use compat ioctl for addfb2 on X86/IA64Kristian H. Kristensen
Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an unaligned 64 bit field (modifier). This get packed differently between 32 bit and 64 bit modes on architectures that can handle unaligned 64 bit access (X86 and IA64). Other architectures pack the structs the same and don't need the compat wrapper. Use the same condition for drm_mode_fb_cmd2 as we use for drm_update_draw. Note that only the modifier will be packed differently between compat and non-compat versions. Reviewed-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Kristian H.

2016-09-14drm/i915: Ignore OpRegion panel type except on select machinesVille Syrjälä
Turns out commit a05628195a0d ("drm/i915: Get panel_type from OpRegion panel details") has regressed quite a few machines. So it looks like we can't use the panel type from OpRegion on all systems, and yet we absolutely must use it on some specific systems. Despite trying, I was unable to find any automagic way to determine if the OpRegion panel type is respectable or not. The only glimmer of hope I had was bit 8 in the SCIC response, but that turned out to not work either (it was always 0 on both types of systems). So, to fix the regressions without breaking the machine we know to need the OpRegion panel type, let's just add a quirk for this. Only specific machines known to require the OpRegion panel type will therefore use it. Everyone else will fall bck to the VBT panel type. The only known machine so far is a "Conrac GmbH IX45GM2". The PCI subsystem ID on this machine is just a generic 8086:2a42, so of no use. Instead we'll go with a DMI match. I suspect we can now also revert commit aeddda06c1a7 ("drm/i915: Ignore panel type from OpRegion on SKL") but let's leave that to a separate patch. v2: Do the DMI match in the opregion code directly, as dev_priv->quirks gets populated too late Cc: Rob Kramer <rob@solution-space.com> Cc: Martin van Es <martin@mrvanes.com> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: Dave Airlie <airlied@linux.ie> Cc: Marco Krüger <krgsch@gmail.com> Cc: Sean Greenslade <sean@seangreenslade.com> Cc: Trudy Tective <bertslany@gmail.com> Cc: Robin Müller <rm1990@gmx.de> Cc: Alexander Kobel <a-kobel@a-kobel.de> Cc: Alexey Shumitsky <alexey.shumitsky@gmail.com> Cc: Emil Andersen Lauridsen <mine809@gmail.com> Cc: oceans112@gmail.com Cc: James Hogan <james@albanarts.com> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: stable@vger.kernel.org References: https://lists.freedesktop.org/archives/intel-gfx/2016-August/105545.html References: https://lists.freedesktop.org/archives/dri-devel/2016-August/116888.html References: https://lists.freedesktop.org/archives/intel-gfx/2016-June/098826.html Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=94825 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97060 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97443 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97363 Fixes: a05628195a0d ("drm/i915: Get panel_type from OpRegion panel details") Tested-by: Marco Krüger <krgsch@gmail.com> Tested-by: Alexey Shumitsky <alexey.shumitsky@gmail.com> Tested-by: Sean Greenslade <sean@seangreenslade.com> Tested-by: Emil Andersen Lauridsen <mine809@gmail.com> Tested-by: Robin Müller <rm1990@gmx.de> Tested-by: oceans112@gmail.com Tested-by: Rob Kramer <rob@solution-space.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1473758539-21565-1-git-send-email-ville.syrjala@linux.intel.com References: http://patchwork.freedesktop.org/patch/msgid/1473602239-15855-1-git-send-email-adrienverge@gmail.com Acked-by: Jani Nikula <jani.nikula@intel.com> (cherry picked from commit c8ebfad7a063fe665417fa0eeb0da7cfe987d8ed) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2016-09-14Revert "drm/i915/psr: Make idle_frames sensible again"Rodrigo Vivi
This reverts commit 1c80c25fb622973dd135878e98d172be20859049 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed May 18 18:47:12 2016 +0200 drm/i915/psr: Make idle_frames sensible again There are panels that needs 4 idle frames before entering PSR, but VBT is unproperly set. Also lately it was identified that idle frame count calculated at HW can be off by 1, what makes the minimum of 2, at least. Without the current vbt+1 we are with the risk of having HW calculating 0 idle frames and entering PSR when it shouldn't. Regardless the lack of link training.

2016-08-31drm/nouveau/acpi: use DSM if bridge does not support D3coldPeter Wu
Even if PR3 support is available on the bridge, it will not be used if the PCI layer considers it unavailable (i.e. on all laptops from 2013 and 2014). Ensure that this condition is checked to allow a fallback to the Optimus DSM for device poweroff. Initially I wanted to call pci_d3cold_enable before checking bridge_d3 (in case the user changed d3cold_allowed), but that is such an unlikely case and likely fragile anyway.

2016-08-26drm: Protect fb_defio in drivers with CONFIG_KMS_FBDEV_EMULATIONDaniel Vetter
For reasons that entirely elude me fb.h exposes all the structures, even when it is not enabled. Except for special stuff like fb_defio. Which means all the drivers which haven't yet switched over to the defio support in the helpers and still roll their own, will fail to compile when fbdev emulation is disabled. Protect just those bits, as a gnarly reminder that conversion to the core defio helpers would be good.

2016-08-24drm/tegra: dsi: Enhance runtime power managementThierry Reding
The MIPI DSI output on Tegra SoCs requires some external logic to calibrate the MIPI pads before a video signal can be transmitted. This MIPI calibration logic requires to be powered on while the MIPI pads are being used, which is currently done as part of the DSI driver's probe implementation. This is suboptimal because it will leave the MIPI calibration logic powered up even if the DSI output is never used. On Tegra114 and earlier this behaviour also causes the driver to hang while trying to power up the MIPI calibration logic because the power partition that contains the MIPI calibration logic will be powered on by the display controller at output pipeline configuration time. Thus the power up sequence for the MIPI calibration logic happens before it's power partition is guaranteed to be enabled. Fix this by splitting up the API into a request/free pair of functions that manage the runtime dependency between the DSI and the calibration modules (no registers are accessed) and a set of enable, calibrate and disable functions that program the MIPI calibration logic at points in time where the power partition is really enabled. While at it, make sure that the runtime power management also works in ganged mode, which is currently also broken.
