They have an open source userspace built on top of this interface, and the code looks as good as it was going to get out of tree. - Initial atomic modesetting work The need for an atomic modesetting interface to allow userspace to try and send a complete set of modesetting state to the driver has arisen, and been suffering from neglect this past year. No more, the start of the common code and changes for msm driver to use it are in this tree. Ongoing work to get the userspace ioctl finished and the code clean will probably wait until next kernel. - DisplayID 1.3 and tiled monitor exposed to userspace. Tiled monitor property is now exposed for userspace to make use of. - Rockchip drm driver merged. - imx gpu driver moved out of staging Other stuff: - core: panel - MIPI DSI + new panels. expose suggested x/y properties for virtual GPUs - i915: Initial Skylake (SKL) support gen3/4 reset work start of dri1/ums removal infoframe tracking fixes for lots of things. - nouveau: tegra k1 voltage support GM204 modesetting support GT21x memory reclocking work - radeon: CI dpm fixes GPUVM improvements Initial DPM fan control - rcar-du: HDMI support added removed some support for old boards slave encoder driver for Analog Devices adv7511 - exynos: Exynos4415 SoC support - msm: a4xx gpu support atomic helper conversion - tegra: iommu support universal plane support ganged-mode DSI support - sti: HDMI i2c improvements - vmwgfx: some late fixes. - qxl: use suggested x/y properties" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (969 commits) drm: sti: fix module compilation issue drm/i915: save/restore GMBUS freq across suspend/resume on gen4 drm: sti: correctly cleanup CRTC and planes drm: sti: add HQVDP plane drm: sti: add cursor plane drm: sti: enable auxiliary CRTC drm: sti: fix delay in VTG programming drm: sti: prepare sti_tvout to support auxiliary crtc drm: sti: use drm_crtc_vblank_{on/off} instead of drm_vblank_{on/off} drm: sti: fix hdmi avi infoframe drm: sti: remove event lock while disabling vblank drm: sti: simplify gdp code drm: sti: clear all mixer control drm: sti: remove gpio for HDMI hot plug detection drm: sti: allow to change hdmi ddc i2c adapter drm/doc: Document drm_add_modes_noedid() usage drm/i915: Remove '& 0xffff' from the mask given to WA_REG() drm/i915: Invert the mask and val arguments in wa_add() and WA_REG() drm: Zero out DRM object memory upon cleanup drm/i915/bdw: Fix the write setting up the WIZ hashing mode ...

At elast if we timeout there's occasionally still a few hundred us left (in a 2 second timeout). Stuff I've tried and thrown out again: - Sampling the before timestamp before jiffies. Doesn't improve test path rate at all. - Using jiffies. Way to inaccurate, which means way too much drift with signals plus automatic ioctl restarting in userspace. In hindsight we should have used an absolute timeout, but hey we need something for v3 of the i915 gem wait interfaces ;-) - Trying to figure out where accuracy gets lost. gl testcase really don't care all that much about this (as long as isn't not massively off), it's just that the testcase gets a bit upset if it receives an EITME with timeout > 0. So as long as we're in the ballbark it's good enough. So patch everything up if we're at most one jiffies off. I get's me a solid test again.

Which is ok, since that's the way the pointers and so also the refcounts go. But when we drop the reference we must make sure that we remove the branches/ports from the lists/pointers before dropping the reference. Otherwise the get_validated functions will still return it instead of returning NULL (which indicates a potentially on-going unplug). The mst branch destroy gets this right for ports: First it deletes the port from the ports list, then it unrefs. But the ports destroy function gets it wrong: First it unrefs, then it drops the ref. Which means a zombie mst branch can still be validate with get_validated_mstb_ref when it shouldn't. Fix this.

However they are the same physical port in hardware and we can't enable both at the same time. Reject the modeset if the user attempts this. So far we've been saved by the fact that we never see both HDMI and DP connectors as connected. But if the user decides to force a mode anyway, all kinds of funny stuff might happen. Unfortunately we don't seem to have any way to inform userspace that such configurations are invalid except by returning an error from setcrtc. possible_clones only covers real cloning situations, and looking at the connector names doesn't work either since we don't always register both connectors for the same port. I suppose the only way to fix that would be to expose only a single encoder per digital port like we do on HSW+ but that would be a fairly large undertaking for little gain. kms_setmode hits this since it forces modes on non-connected VGA and HDMI connectors. Previosuly it just resulted in weirdness such as failed link training. With this patch it will now get an error back from the kernel and will die with an assert since it thinks that the configuration should be fine. v2: Deal with INTEL_OUTPUT_UNKNOWN (Paulo) Cc: Paulo Zanoni <przanoni@gmail.com> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
