Global edf_sch_get_pdata (task): See sof/schedule/edf_schedule.h.
Global edf_sch_set_pdata (task, data): See sof/schedule/edf_schedule.h.
File edf_schedule.h: Deprecated for modern audio pipeline processing. In Zephyr-based builds, EDF is implemented as a delayed workqueue (edf_workq) retained for host IPC processing and legacy KPB draining tasks until migration. Audio pipeline components should use SOF_SCHEDULE_DP with native Zephyr thread deadlines or SOF_SCHEDULE_LL_TIMER / SOF_SCHEDULE_LL_DMA.
Struct edf_task_pdata: Deprecated along with SOF_SCHEDULE_EDF.
Global heap_trace_all (int force): No-op stub. Heap diagnostics are tracked via Zephyr runtime statistics (CONFIG_SYS_HEAP_RUNTIME_STATS), IPC4 telemetry, and VMH diagnostics (vmh_log_stats()).
Global intel_adsp::LEGACY_STRUCT: New module shall not work with this item as it will be removed in next API release.
File mm_heap.h: Legacy XTOS heap management header. On Zephyr platforms, heap operations are managed by RTOS allocators in <rtos/alloc.h> and Zephyr k_heap; this header is retained solely as an empty compatibility shim.
Global schedule_task_init_edf (struct task *task, const struct sof_uuid_entry *uid, const struct task_ops *ops, void *data, uint16_t core, uint32_t flags): Deprecated for audio pipelines; use scheduler_dp_task_init() instead.
Global scheduler_init_edf (void): Deprecated for audio pipelines; retained for host IPC and legacy KPB draining.
Struct sof_ipc_dma_trace_params: Use sof_ipc_dma_trace_params_ext instead.
Global SOF_MEM_FLAG_LOW_POWER: Legacy flag from XTOS memory partitions; no-op in modern Zephyr heap manager.
Global SOF_MEM_FLAG_NO_COPY: Legacy realloc optimization flag. rbrealloc() and rbrealloc_align() have been removed from the allocation API.
Global SOF_SCHEDULE_EDF: Deprecated for modern audio pipeline processing. In Zephyr-based builds, EDF is implemented as a delayed workqueue (edf_workq) retained for host IPC processing and legacy KPB draining tasks until migration. Audio pipeline components should use SOF_SCHEDULE_DP for preemptible deadline-driven tasks or SOF_SCHEDULE_LL_TIMER / SOF_SCHEDULE_LL_DMA for hard real-time tasks.
