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.

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.

DRM_UT_CORE generates way too much noise usually, so having the framebuffer init failures use DRM_UT_CORE is a pain when trying to find out the reason why you failed in creating a framebuffer.

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:
