This commit allows you to dump different regions of memory related to bvh building. An additional script to decode the memory dump is also added, and you're able to view the built bvh in 3D view in html. See the included README.md for usage. Rework: - you can now view the actual child_coord in internalNode in html - change exponent to be int8_t in the interpreter - fix the actual coordinates using an updated formula - now you can have 3D view of the bvh - blockIncr could be 2 and vk_aabb should be first - Now, if any bvh dump is enabled, we will zero out tlas, to prevent gpu hang caused by incorrect tlas traversal - rootNodeOffset is back to the beginning - Add INTEL_DEBUG=bvh_no_build. - Fix type of dump_size - add assertion for a 4B alignment - when clearing out bvh, only clear out everything after (header+bvh_offset) - TODO: instead of dumping on destory, track in the command buffer Acked-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/31588>
