There is no point in setting intel_dp->compliance.test_type, and proceeding with the autotests, if we're about to NAK the request.

The GPU may be in an unknown state following resume and module load. The previous occupant may have left contexts loaded, or other dangerous state, which can cause an immediate GPU hang for us. The only save course of action is to reset the GPU prior to using it - similarly to how we reset the GPU prior to unload (before a second user may be affected by our leftover state). We need to reset the GPU very early in our load/resume sequence so that any stale HW pointers are revoked prior to any resource allocations we make (that may conflict). A reset should only be a couple of milliseconds on a slow device, a cost we should easily be able to absorb into our initialisation times. Signed-off-by:

In order to reset the GPU early on in the module load sequence, we need to allocate the basic engine structs (to populate the mmio offsets etc). Currently, the engine initialisation allocates both the base struct and also allocate auxiliary objects, which depend upon state setup quite late in the load sequence. We split off the allocation callback for later and allow ourselves to allocate the engine structs themselves early. v2: Different paint for the unwind following error. Signed-off-by:

Since tweaking i915_vma_compare() we allowed constructors to skip clearing the ggtt_view believing that we didn't access the unused members. That, as it turns out, was not entirely true. In particular, i915_gem_fault() uses ret = remap_io_mapping(area, area->vm_start + (vma->ggtt_view.partial.offset << PAGE_SHIFT), (ggtt->mappable_base + vma->node.start) >> PAGE_SHIFT, min_t(u64, vma->size, area->vm_end - area->vm_start), &ggtt->mappable); i.e. the ggtt_view.partial for both normal and partial views. If we allowed garbage into the normal vma->ggtt_view and then try userspace tried to mmap it, we could explode in an unobvious fashion.

This reverts commit 527b6abe (Revert "drm/i915: Use atomic commits for legacy page_flips") and reapplies commit ee042aa4. ("drm/i915: Use atomic commits for legacy page_flips") The reason for the revert was because legacy cursor updates were forced to wait for pending page flips and rendering after they were converted to atomic. Commit f79f2692 (drm/i915: Add a cursor hack to allow converting legacy page flip to atomic, v3) adds a fastpath to cursor updates, which fixes the stuttering issues. With these changes I feel confident enough to re-enable cursor updates. Legacy cursor update won't block in the following cases: - Moving cursor - Changing cursor fb The legacy cursor update will still block in the following cases: - Showing/hiding cursor. - Cursor size or scaling changes. - cursor update while cursor is invisible (could be fixed, if it turns out to be important). - Cursor tiling changes (Not sure we support tiled cursors.) - Last update was a modeset.

Parameters tile_size, tile_width and tile_height were passed in the wrong order to _intel_adjust_tile_offset() when calculating the rotated offsets. This doesn't fix any user visible bug, since for packed formats new and old offset are the same and the rotated offsets are within a tile before they are fed to _intel_adjust_tile_offset(). In that case, the offsets are unchanged. That is not true for planar formats, but those are currently not supported.

When we reach the user's RPS limits, stop requesting an adjustment. Even though we will clamp the requested frequency later, we rely on interrupt masking to disable further adjustments in the same direction. Even though it is unlikely (one scenario is a bug in the driver, another is careful manipulation through the uAPI) if we keep exponentially increasing the adjustment value, it will wrap and cause a negative adjustment.

With the introduce of i915_vma_instance() for obtaining the VMA singleton for a (obj, vm, view) tuple, we can remove the i915_vma_create() in favour of a single entry point.
