"drm/i915/uapi: Add query for hwconfig blob" was changed: * Rename DRM_I915_QUERY_HWCONFIG_TABLE to DRM_I915_QUERY_HWCONFIG_BLOB as requested by Joonas. * Reword commit message * I added Acked-by to this patch, but this Acked-by only applies in the context of this version of the patchset. "drm/i915/uapi: Add struct drm_i915_query_hwconfig_blob_item" adds a struct to the uAPI and documents the return value for DRM_I915_QUERY_HWCONFIG_BLOB. (Except, keys / values are still deferred to the PRM.) "drm/i915/guc: Verify hwconfig blob matches supported format" does the simple verification of the blob to make sure it matches what the uAPI documents. v2: * Fix -Werror errors. * Rebase to drm-intel/for-linux-next instead of drm-intel/for-linux-next-gt, as this seems to be what CI wants. * Fix u32 -> __u32. * Add commit message for "Verify hwconfig blob" patch as requested by Tvrtko. * Reword text added to i915_drm.h as requested by Tvrtko. (Attempting to indicate the overall blob ends right at the last blob item.) v3: * Add several changes suggested by Tvrtko in the "Verify hwconfig blob", along with some tweaks to i915_drm.h from the feedback for the same patch. v4: * Rewrite verify_hwconfig_blob() to hopefully be clearer without relying on comments so much, and add various suggestions from Michal. * Michal also had some suggestions in John's "drm/i915/guc: Add fetch of hwconfig table" patch. I held off on making any of these changes in this version. v5: * Add many changes suggested by Michal in John's "drm/i915/guc: Add fetch of hwconfig table" patch. * Fix documenation formatting as suggested by Daniel in "drm/i915/uapi: Add struct drm_i915_query_hwconfig_blob_item" v6: * Updated "drm/i915/guc: Add fetch of hwconfig table" by merging in John's v2 patch which saves the hwconfig blob at the GT level. I also added a few changes requested by Michal on the v5 posting. * Tvrtko requested an example of UMD using the i915 hwconfig interface.
