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. We do incur a lookup onto an empty tree, but the i915_vma_create() were being called infrequently and during initialisation, so the small overhead is negligible. v2: Drop the i915_ prefix from the now static vma_create() function Signed-off-by:

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.

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 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.
