Check that the sink really declared 12bpc support before we enable it. This should not actually never happen since it's mandatory for HDMI sinks to support 12bpc if they support any deep color modes. But reality disagrees with the theory and there are actually sinks in the wild that violate the spec. v2: Fix the output_types check Update commit message to state that these things are in fact real Cc: stable@vger.kernel.org Cc: Nicholas Sielicki <nicholas.sielicki@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=99250Signed-off-by:Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170213175818.24958-1-ville.syrjala@linux.intel.comReviewed-by:

The REDIRECT_TO_GUC bit is a strange beast as it is a disable bit - setting the bit in the pm interrupt generation stops the interrupt going to the guc (not sending it to the guc as the name implies).

We don't use the error return for anything other than reporting and logging that there is no VBT. We can pull the logging in the function, and remove the error status return. Moreover, if we needed the information for something later on, we'd probably be better off storing the bit in dev_priv, and using it where it's needed, instead of using the error return. While at it, improve the comments. Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Currently, we sum the render and media cycles (on different engines) to compute a percentage - but we fail to factor in the duplication into the threshold calculations. This makes us very eager to upclock! If we just consider the maximum busy cycles of either counter, we should have an accurate reflection on whether there are cycles to spare to handle the workload at this frequency. Signed-off-by:

On Baytrail, we manually calculate busyness over the evaluation interval to avoid issues with miscaluations with RC6 enabled. However, it turns out that the DOWN_EI interrupt generator is completely bust - it operates in two modes, continuous or never. Neither of which are conducive to good behaviour. Stop unmask the DOWN_EI interrupt and just compute everything from the UP_EI which does seem to correspond to the desired interval. v2: Fixup gen6_rps_pm_mask() as well v3: Inline vlv_c0_above() to combine the now identical elapsed calculation for up/down and simplify the threshold testing Fixes: 43cf3bf0 ("drm/i915: Improved w/a for rps on Baytrail") Signed-off-by:

Sometimes we want to explicitly page out all available objects from igt, i.e. call i915_gem_shrink_all() and check that subsequent operations succeed. This adds DROP_SHRINK_ALL [0x8] to the set of flags for debugfs/i915_drop_caches for that purpose. Signed-off-by:

We only need to clflush those cachelines that we have validated to be read by the GPU. Userspace typically fills the batch length in correctly, the exceptions tend to be explicit tests within igt. v2: Use ptr_mask_bits() to make Mika happy v3: cmd is not advanced on MI_BBE, so make sure to include an extra dword in the clflush.

In commit 003342a5 ("drm/i915: Keep track of active forcewake domains in a bitmask") I forgot to adjust the newly introduce fw_domains_active state across reset. This caused the assert_forcewakes_inactive to trigger during suspend and resume if there were user held forcewakes. v2: Bitmask checks are required since vfuncs are not always present. v3: Move bitmask tracking to get/put vfunc for simplicity.

In I915 driver, there are many places where variable name for intel_encoder object is given as 'intel_encoder' whereas it would make more sense to call it just 'encoder' when possible. This patch does this cleanup in file intel_ddi.c. PS: There are few functions where both drm_encoder and intel_encoder are present. For such functions, this patch does nothing. Suggested-by:

Driver needs to ensure that it doesn't mask the PM interrupts, which are unmasked/needed by GuC firmware. For that, Driver maintains a bitmask of interrupts to be kept unmasked, pm_intr_keep. pm_intr_keep was determined across GuC load. GuC gets loaded in different scenarios and it is not going to change the pm_intr_keep so this patch moves its setup to intel_irq_init. This patch fixes incorrect RPS masking leading to UP interrupts triggered even when at cur_freq=max and inversly for Down interrupts.

It looks like we were incorrectly comparing vma->node against itself instead of the target node, when evicting for a node on systems where we need guard pages between regions with different cache domains. As a consequence we can end up trying to needlessly evict neighbouring nodes, even if they have the same cache domain, and if they were pinned we would fail the eviction.

If another thread tries to remap the GGTT over the userptr before the worker is scheduled, it will be stopped by its invalidate-range flushing the current work, before the deadlock can occur. v2: Improve discussion of how we end up in the deadlock. v3: Don't forget to mark the userptr as active after a successful gup_fast. Rename overlaps_ggtt to noncontiguous_or_overlaps_ggtt. v4: Fix test ordering between invalid GTT mmaping and range completion (Tvrtko) Reported-by:

To avoid waiting for work from other invalidate-range threads where not required, only wait on the userptr cancel workqueue if we have added some work to it. Signed-off-by:

If the worker fails, it no longer has pages to release and can be immediately removed from the invalidate-tree. Signed-off-by:

The trouble here is that looking at all connector->state in the verifier isn't good, because that's run from the commit work, which doesn't hold the connection_mutex. Which means we're only allowed to look at states in our atomic update. The simple fix for future proofing would be to switch over to drm_for_each_connector_in_state, but that has the problem that the verification then fails if not all connectors are in the state. And we also need to be careful to check both old and new encoders, and not screw things up when an encoder gets reassigned. Note that this isn't the full fix, since we still look at connector->state. To fix that, we need Maarten's patch series to switch over to state pointers within drm_atomic_state, but that's a different series. v2: Use oldnew iterator (Maarten). v3: Rebase onto the iter_get/put->iter_begin/end rename.

This gets rid of the last users of for_each_intel_connector(), remove that too. At first I wasn't sure whether the 2 loops in the modeset state checker should instead only loop over the connectors in the atomic commit. But we never add connectors to an atomic update if they don't (or won't have) a CRTC assigned, which means there'd be a gap in check coverage. Hence loop over everything on those too. v2: Rebase onto the iter_get/put->iter_begin/end rename.

Drive-by fixup while looking at all the connector_list walkers - holding connection_mutex does actually _not_ give you locking to look at the legacy drm_connector->encoder->crtc pointer chain. That one is solely owned by the atomic commit workers. Instead we must inspect the atomic state. Reviewed-by:
