Whilst writing testcases to exercise the VMA API, some oddities came to light, such as i915_gem_obj_lookup_or_create(). Joonas suggested i915_vma_instance() as a neat replacement, so rename them, move them to i915_vma.c and add some kerneldoc as a sugary bonus. s/i915_gem_obj_to_vma/i915_vma_lookup/ s/i915_gem_obj_lookup_or_create_vma/i915_vma_instance/ Suggested-by:

With atomic plane states we are able to track an allocation right from preparation, during use and through to the final free after being swapped out for a new plane. We can couple the VMA we pin for the framebuffer (and its rotation) to this lifetime and avoid all the clumsy lookups in between. v2: Remove residual vma on plane cleanup (Chris) v3: Add a description for the vma destruction in intel_plane_destroy_state (Maarten) References: https://bugs.freedesktop.org/show_bug.cgi?id=98829Signed-off-by:Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170116152131.18089-1-chris@chris-wilson.co.ukAcked-by:

This patch will allow for getparams to return the status of the HuC. As the HuC has to be validated by the GuC this patch uses the validated status to show when the HuC is loaded and ready for use. You cannot use the loaded status as with the GuC as the HuC is verified after it is loaded and is not usable until it is verified. v2: removed the forewakes as the registers are already force-woken. (T.Ursulin) v3: rebased on top of drm-tip. Removed any reference to intel_huc.h v4: rebased. Rename I915_PARAM_HAS_HUC to I915_PARAM_HUC_STATUS. Remove intel_is_huc_valid() since it is used only in one place. Put the case of I915_PARAM_HAS_HUC() in the right place. v5: rebased. Add a comment to specify that I915_READ(reg) does not read garbage value. The register HUC_STATUS2 is force woken and no rpm is needed.

The HuC authentication is done by host2guc call. The HuC RSA keys are sent to GuC for authentication. v2: rebased on top of drm-tip.

Rename intel_huc_auh() to intel_guc_auth_huc() and place the prototype in intel_guc.h,correct the comments. v5: rebased.

The HuC loading process is similar to GuC. The intel_uc_fw_fetch() is used for both cases. HuC loading needs to be before GuC loading. The WOPCM setting must be done early before loading any of them. v2: rebased on-top of drm-intel-nightly. removed if(HAS_GUC()) before the guc call. (D.Gordon) update huc_version number of format. v3: rebased to drm-intel-nightly, changed the file name format to match the one in the huc package. Changed dev->dev_private to to_i915() v4: moved function back to where it was. change wait_for_atomic to wait_for. v5: rebased. Changed the year in the copyright message to reflect the right year.Correct the comments,remove the unwanted WARN message, replace drm_gem_object_unreference() with i915_gem_object_put().Make the prototypes in intel_huc.h non-extern. v6: rebased. Update the file construction done by HuC. It is similar to GuC.Adopted the approach used in- https://patchwork.freedesktop.org/patch/104355/ <Tvrtko Ursulin> v7: Change dev to dev_priv in macro definition. Corrected comments. v8: rebased on top of drm-tip. Updated functions intel_huc_load(), intel_huc_init() and intel_uc_fw_fetch() to accept dev_priv instead of dev. Moved contents of intel_huc.h to intel_uc.h. v9: change SKL_FW_ to SKL_HUC_FW_. Add intel_ prefix to guc_wopcm_size(). Remove unwanted checks in intel_uc.h. Rename huc_fw in struct intel_huc to simply fw to avoid redundency. v10: rebased. Correct comments. Make intel_huc_fini() accept dev_priv instead of dev like intel_huc_init() and intel_huc_load().Move definition to i915_guc_reg.h from intel_uc.h. Clean DMA_CTRL bits after HuC DMA transfer in huc_ucode_xfer() instead of guc_ucode_xfer(). Add suitable WARNs to give extra info. v11: rebased. Add proper bias for HuC and make sure there are asserts on failure by using guc_ggtt_offset_vma(). Introduce intel_huc.c and remove intel_huc_loader.c since it has functions that do more than just loading.Correct year in copyright. v12: remove invalidates that are not required anymore.

Since we now only skip banned contexts, preventing the skip of default contexts is no longer sensible. For a similar argument as before 'commit 7ec73b7e ("drm/i915: Only skip requests once a context is banned")' we end up with an inconsistent API if we only mark future execbufs from the default ctx as banned but fail to mark those currently executing as failed.

When the plane is invisible we may have all sorts of bogus stuff in the coordinates, which we must ignore or else we might fail the plane update. This started to happen on SKL when I moved the plane offset computation to happen in the check phase. Previously we happily ignored it all since we never called the update_plane hook with an invisible plane.

Some engines are never user or already sitting idle in the kernel context and for those we can skip flushing the current context for i915_gem_switch_to_kernel_context(). We used to perform this optimisation but that was removed for convenience of converting over to multiple timelines and handling the pending request queues. From the perspective of writing selftests, reducing the number of background operations on the engines makes defining assertions easier. Signed-off-by:

As we now have the ability to directly reset the GPU from the waiter (and so do not need to drop the lock in order to let the reset proceed) and also do not lose requests over a reset, we can now simply queue the request to occur after the reset rather than roundtripping to userspace (or worse failing with EIO).

It is only being used to clear a struct and set the type, after which it is overwritten. Since we no longer check the unset bits of the union, skipping the clear is permissible. Signed-off-by:

Reading the ggtt_views is much more pleasant without the extra characters from specifying the union (i.e. ggtt_view.partial rather than ggtt_view.params.partial). To make this work inside i915_vma_compare() with only a single memcmp requires us to ensure that there are no uninitialised bytes within each branch of the union (we make sure the structs are packed) and we need to store the size of each branch. v4: Rewrite changelog and add comments explaining the assert.

Chris Wilson authored
In preparation for the next patch to convert to using an anonymous union and leaving the excess bytes in the union uninitialised, we first need to make sure we do not compare using those uninitialised bytes. We also want to preserve the compactness of the code, avoiding a second call to memcmp or introducing a switch, so we take advantage of using the type as an encoded size (as well as a unique identifier for each type of view). v2: Add the rationale for why we encode size into ggtt_view.type as a comment before the memcmp() v3: Use a switch to also assert that no two i915_ggtt_view_type have the same value.

In the next few patches, we will depend upon there being no uninitialised bits inside the ggtt_view. To ensure this we add the __packed attribute and double check with a build bug that gcc hasn't expanded the struct to include some padding bytes. Signed-off-by:
