"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 only applies in the context of this version of the patchset. If my changes are rejected, then please *do not* add my Acked-by to the other series. In particular, I do not want my Acked-by on the patch if the patch mentions the HWCONFIG format, but is not willing to add that to the actual uAPI. I also do not want my Acked-by on it if it mentions "consolidation" of this data. Since we are dealing with open source projects (aside from GuC), this doesn't seem appropriate. "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.
