While introducing HDMI support, component matching on connectors node were bypassed since no driver would actually bind on the DT node. But when only a CVBS connector is present, only a single node is found in the graph, but ignored and a NULL match table is given to the component code. This code permits bypassing the components framework by binding directly the DRM driver when no components needs to be loaded.

The scanline counter is bonkers on VLV/CHV DSI. The scanline counter increment is not lined up with the start of vblank like it is on every other platform and output type. This causes problems for both the vblank timestamping and atomic update vblank evasion. On my FFRD8 machine at least, the scanline counter increment happens about 1/3 of a scanline ahead of the start of vblank (which is where all register latching happens still). That means we can't trust the scanline counter to tell us whether we're in vblank or not while we're on that particular line. In order to keep vblank timestamping in working condition when called from the vblank irq, we'll leave scanline_offset at one, which means that the entire line containing the start of vblank is considered to be inside the vblank. For the vblank evasion we'll need to consider that entire line to be bad, since we can't tell whether the registers already got latched or not. And we can't actually use the start of vblank interrupt to get us past that line as the interrupt would fire too soon, and then we'd up waiting for the next start of vblank instead. One way around that would using the frame start interrupt instead since that wouldn't fire until the next scanline, but that would require some bigger changes in the interrupt code. So for simplicity we'll just poll until we get past the bad line. v2: Adjust the comments a bit Cc: stable@vger.kernel.org Cc: Jonas Aaberg <cja@gmx.net> Tested-by: NJonas Aaberg <cja@gmx.net> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=99086Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20161215174734.28779-1-ville.syrjala@linux.intel.comTested-by: NMika Kahola <mika.kahola@intel.com> Reviewed-by: NMika Kahola <mika.kahola@intel.com> (cherry picked from commit ec1b4ee2) Signed-off-by: NJani Nikula <jani.nikula@intel.com>

Commit 7c3f86b6 ("drm/i915: Invalidate the guc ggtt TLB upon insertion") added the restoration of the invalidation routine after the GuC was disabled, but missed that the GuC was unconditionally disabled when not used. This then overwrites the invalidate routine for the older chipsets, causing havoc and breaking resume as the most obvious victim. We place the guard inside i915_ggtt_disable_guc() to be backport friendly (the bug was introduced into v4.11) but it would be preferred to be in more control over when this was guard (i.e. do not try and teardown the data structures before we have enabled them). That should be true with the reorganisation of the guc loaders.

Since commit bac2a909 Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Date: Wed Jan 21 02:17:42 2015 +0100 PCI / PM: Avoid resuming PCI devices during system suspend PCI devices will default to allowing the system suspend complete optimization where devices are not woken up during system suspend if they were already runtime suspended. This however breaks the i915/HDA drivers for two reasons: - The i915 driver has system suspend specific steps that it needs to run, that bring the device to a different state than its runtime suspended state. - The HDA driver's suspend handler requires power that it will request from the i915 driver's power domain handler. This in turn requires the i915 driver to runtime resume itself, but this won't be possible if the suspend complete optimization is in effect: in this case the i915 runtime PM is disabled and trying to get an RPM reference returns -EACCESS. Solve this by requiring the PCI/PM core to resume the device during system suspend which in effect disables the suspend complete optimization. Regardless of the above commit the optimization stayed disabled for DRM devices until commit d14d2a84 Author: Lukas Wunner <lukas@wunner.de> Date: Wed Jun 8 12:49:29 2016 +0200 drm: Remove dev_pm_ops from drm_class so this patch is in practice a fix for this commit. Another reason for the bug staying hidden for so long is that the optimization for a device is disabled if it's disabled for any of its children devices. i915 may have a backlight device as its child which doesn't support runtime PM and so doesn't allow the optimization either. So if this backlight device got registered the bug stayed hidden. Credits to Marta, Tomi and David who enabled pstore logging, that caught one instance of this issue across a suspend/ resume-to-ram and Ville who rememberd that the optimization was enabled for some devices at one point.

Allow intel_engine_is_idle() to be called outside of the GT wakeref by acquiring the device runtime pm for ourselves. This allows the function to act as check after we assume the engine is idle and we release the GT wakeref held whilst we have requests. At the moment, we do not call it outside of an awake context but taking the wakeref as required makes it more convenient to use for quick debugging in future.

The previous attempt at this had an issue with with num_clips > 1 because it would always end up using the coordinates of the last clip while using width and height calculated from the bounding box of all the clips. So if the last clip happens to be not at the top-left corner of the bounding box, the CPU blit operation would go out of bounds. The original intent was to coalesce all the clips into one blit, and to do that we need to also track the starting point of the content buffer.

BXT has a H/W issue with IOMMU which can lead to system hangs when Aperture accesses are queued within the GAM behind GTT Accesses. This patch avoids the condition by wrapping all GTT updates in stop_machine and using a flushing read prior to restarting the machine. The stop_machine guarantees no new Aperture accesses can begin while the PTE writes are being emmitted. The flushing read ensures that any following Aperture accesses cannot begin until the PTE writes have been cleared out of the GAM's fifo. Only FOLLOWING Aperture accesses need to be separated from in flight PTE updates. PTE Writes may follow tightly behind already in flight Aperture accesses, so no flushing read is required at the start of a PTE update sequence. This issue was reproduced by running igt/gem_readwrite and igt/gem_render_copy simultaneously from different processes, each in a tight loop, with INTEL_IOMMU enabled. This patch was originally published as: drm/i915: Serialize GTT Updates on BXT [Note: This will cause a performance penalty for some use cases, but avoiding hangs trumps performance hits. This may need to be worked around in Mesa to recover the lost performance.] v2: Move bxt/iommu detection into static function Remove #ifdef CONFIG_INTEL_IOMMU protection Make function names more reflective of purpose Move flushing read into static function v3: Tidy up for checkpatch.pl Testcase: igt/gem_concurrent_blit Signed-off-by: NJon Bloomfield <jon.bloomfield@intel.com> Cc: John Harrison <john.C.Harrison@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: stable@vger.kernel.org Link: http://patchwork.freedesktop.org/patch/msgid/1495641251-30022-1-git-send-email-jon.bloomfield@intel.comReviewed-by: NTvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> (cherry picked from commit 0ef34ad6) Signed-off-by: NJani Nikula <jani.nikula@intel.com>

The description of the CSI_SEL bit in the i.MX6 reference manual is incorrect. It states "This bit defines which CSI is the input to the IC. This bit is effective only if IC_INPUT is bit cleared". From experiment it was found this is in fact not correct. The CSI_SEL bit selects which CSI is input to _both_ the VDIC _and_ the IC. If the IC_INPUT bit is set so that the IC is receiving from the VDIC, the IC ignores the CSI_SEL bit, but CSI_SEL still selects which CSI the VDIC receives from in that case.

4 nouveau regression fixes. * 'linux-4.12' of git://github.com/skeggsb/linux: drm/nouveau/tmr: fully separate alarm execution/pending lists drm/nouveau: enable autosuspend only when it'll actually be used drm/nouveau: replace multiple open-coded runpm support checks with function drm/nouveau/kms/nv50: add null check before pointer dereference

Reusing the list_head for both is a bad idea. Callback execution is done with the lock dropped so that alarms can be rescheduled from the callback, which means that with some unfortunate timing, lists can get corrupted. The execution list should not require its own locking, the single function that uses it can only be called from a single context.

This prevents a deadlock that somehow results from the suspend() -> forbid() -> resume() callchain.
