From fbe3a23c011ba745bab503ef828c8d729d52b81e Mon Sep 17 00:00:00 2001 From: Jyri Sarha Date: Wed, 17 Sep 2025 19:42:24 +0300 Subject: [PATCH 1/7] ASoC: SOF: ipc4-topology: Remove dp_ from all module memory attributes Remove dp-prefix from all module instance's memory attributes and related data structures. The attributes are not anymore exclusively for Data Processing module instances, but generic for all module instances. However, the module init payload is still only for DP module instances.

The payload contains information for payload specific memory configuration. All non DP module instances within the same pipeline share the same memory attributes and access the same resources. The new logic sums interim, lifetime, and shared heap memory requirements together and picks the highest stack requirement of all module instances belonging to a pipeline. These pipeline specific attributes are sent as struct sof_ipc4_glb_pipe_payload payload in pipeline's create message. The idea is to pass common memory configuration for all the Low Latency modules in the pipeline in pipeline create message payload. The Data Processing module instances will still have an individual memory configuration in struct sof_ipc4_mod_init_ext_dp_memory_data payloads as before. In their payload everything is as it was before, all attributes are copied directly from their topology attributes.
