drm/i915/huc: Add HuC fw loading support 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.

drm/i915/guc: Rename guc_ggtt_offset to intel_guc_ggtt_offset GuC related exported functions should start with "intel_guc_" prefix and pass intel_guc as the first parameter since its GuC related. Current guc_ggtt_offset() failed to follow this code convention and this is a problem for future patches that needs to access intel_guc data to verify the GGTT offset against the GuC WOPCM top. This patch renames the guc_ggtt_offset to intel_guc_ggtt_offset and updates the related code to pass intel_guc pointer to this function call, so that we can have a unified coding style for GuC code and also enable the future patches to get GuC related data from intel_guc to do the offset verification. Meanwhile, this patch also moves the GUC_GGTT_TOP from intel_guc_regs.h to intel_guc.h since it is not GuC register related definition. v8: - Fixed coding style issues and moved GUC_GGTT_TOP to intel_guc.h (Sagar) - Updated commit message to explain to reason and motivation to add intel_guc as the first parameter of intel_guc_ggtt_offset (Chris) v9: - Fixed code alignment issue due to line break (Chris) v10: - Removed unnecessary comments, redundant code and avoided reuse variable to avoid potential issues (Joonas) v13: - Updated the ordering of s-o-b/cc/r-b tags (Sagar) Signed-off-by: Jackie Li <yaodong.li@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Sagar Arun Kamble <sagar.a.kamble@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Sagar Arun Kamble <sagar.a.kamble@intel.com> (v8) Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> (v9) Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> (v11) Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> (v12) Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1520987574-19351-1-git-send-email-yaodong.li@intel.com
