Pull request overview
This PR optimizes memory usage in LLEXT (Loadable EXTensions) builds by moving trace context declarations from global scope to monolithic build sections. The trace contexts are only needed when building modules directly into the base firmware, not when building loadable extensions.
Changes:
- Removed global DECLARE_TR_CTX declarations from 38 audio module files
- Re-added DECLARE_TR_CTX declarations within
#elseblocks (non-LLEXT/monolithic builds) where DECLARE_MODULE_ADAPTER is used - Removed EXPORT_SYMBOL(tflm_tr) from tensorflow module as it's no longer globally accessible
