Hello, extended firmware manifest is a method to retrieve capabilities directly from the firmware file instead of routing the information via the DSP and reading it back via IPC (latter mechanism still supported but will be deprecated). This feature was briefly merged to 5.8 with the series sent on 2020-Apr-15, but due to a regression hit with exporting uapi headers, the patches got dropped. Here's an update with the uapi header issue fixed, rebased to latest 'for-5.8' and a few minor fixes. This has been sitting in sof-dev for some weeks and no further issues have been found. We also added a check for the uapi-export case to SOF CI, so such errors would not slip through again in the future. Tooling support to create firmware files with an extended header is available in SOF firmware repository (see the rimage tool) and this part is already merged.
