In order to ensure no missed interrupts we must first re-direct the interrupts to GuC, and only then re-submit the requests to be replayed after a GPU reset. Otherwise context switch can fire before GuC has been set up to receive it triggering more hangs. v2: Rebase. Signed-off-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.

printks are slow so we should not be doing them from the vblank evade critical section. These could explain why we sometimes seem to blow past our 100 usec deadline. The problem has been there ever since commit c331879c ("drm/i915: skylake sprite plane scaling using shared scalers.") but it may not have been readily visible until commit e1edbd44 ("drm/i915: Complain if we take too long under vblank evasion.") increased our chances of noticing it.

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.

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.

To make life easier let's allow skl_plane_stride() to be called for the AUX surface even when there is no AUX surface. Avoids special cases in the callers. Signed-off-by:

Let's try to keep the alignment requirements in one place, and so towards that end let's move the AUX_DIST alignment handling into intel_surf_alignment() alongside the main surface alignment stuff. Signed-off-by:

under virtualization enviroment, it is possible guest update pipe registers across vblank intervals due to overhead of mmio traps or vm schedule out. However, it is safe since those pipe update happen in virual registers and will not be committed to hardware. suppress that atomic commit error message under virtualization case to avoid confusing user. v2: per ville's comment: return early and against Maarten's patch v3: coding style clean Signed-off-by:

printks are slow so we should not be doing them from the vblank evade critical section. These could explain why we sometimes seem to blow past our 100 usec deadline. The problem has been there ever since commit bfd16b2a ("drm/i915: Make updating pipe without modeset atomic.") but it may not have been readily visible until commit e1edbd44 ("drm/i915: Complain if we take too long under vblank evasion.") increased our chances of noticing it.

Backmerge drm-next to get at all the good stuff in drm-misc. We need that because: - drm_connector_list_iter conversion for i915 needs the core patches. - Maarten's patches to use the new atomic state iterators also need the core patches. - We need the new link status property to complete the DP retraining work, merging through 2 branches wasn't a good idea and we had to partially backtrack. - Chris needs reservation_object_trylock and we want to roll out kref_read everywhere.

Before we instantiate/pin the backing store for our use, we can prepopulate the shmemfs filp efficiently using a write into the pagecache. We avoid the penalty of instantiating all the pages, important if the user is just writing to a few and never uses the object on the GPU, and using a direct write into shmemfs allows it to avoid the cost of retrieving a page (mostly the clear-before-use, but in theory we could curtail swapin) before it is overwritten. This can be extended later to provide additional specialisation for other backends (other than shmemfs). For now it provides a defense against very large write-only allocations from exhausting all of system memory. v2: Smelling fixes.

Once the object has been truncated, it is unrecoverable. To facilitate detection of this state store the error in obj->mm.pages. This is required for the next patch which should be applied to v4.10 (via stable), so we also need to mark this patch for backporting. In that regard, let's consider this to be a fix/improvement too. v2: Avoid dereferencing the ERR_PTR when freeing the object.

The IS_G4X macro is defined as IS_G45 || IS_GM45. We have two points in our code where we have an if statement checking for GM45 followed by an else if statement checking for IS_G4X. This can be confusing since the IS_G4X check won't be catching the previously-checked GM45. Someone quickly trying to check which functions run on each platform may end up getting confused while reading the code. Fix the potential confusion by limiting the else if statements to only check for the platform that was not already checked earlier in the if ladder. Signed-off-by:

In order for the missed-irq update to take effect, the device must be idle. So when the user updates the fault injection via debugfs, idle the device. v2: Idle is explicitly required for setting test_irq, and good behaviour for clearing the missed_irq. v3: Use matching types; expanding to more than ulong rings is left as an exercise to the reader.
