What do you think? I already sent a patchset to replace steps in v3d_lookup_bos() by drm_gem_objects_lookup(), as I mentioned. The patchset is here: https://patchwork.freedesktop.org/series/101610/ Willing to review it? ^ Thanks, Melissa > if (!job->bo) { > DRM_DEBUG("Failed to allocate validated BO pointers\n"); > return -ENOMEM; > -- > 2.31.1 >
