This patch: - adds a new subquery (AMDGPU_INFO_UQ_FW_AREAS) in AMDGPU_INFO_IOCTL to get the size and alignment of shadow and csa objects from the kernel. This information is required for a userqueue consumer (like MESA/libdrm) to create the userqueue metadata objects properly. - also adds supporting metadata structures and a high level wrapper function (amdgpu_query_uq_metadata_info) to the query, to make it easy to use. The corresponding kernel changes for this UAPI extension can be found in amd-gfx mailing list, link: https://patchwork.freedesktop.org/patch/621390/?series=139715&rev=2 This patch adds support only for the GFX IP, and the other engines may be supported in subsequent development.
