Pull Request Overview

This PR converts several audio modules (TDFB, template, tensorflow, up down mixer, and volume) to use a new module-based memory allocation API. The changes replace direct memory allocation calls with module-aware allocation functions and remove manual memory cleanup since the module framework now handles this automatically.

Key changes:

Replace rzalloc(), rmalloc(), and rballoc() with mod_zalloc(), mod_alloc(), and mod_balloc()
Remove manual rfree() calls as memory is now managed by the module framework
Update function signatures to pass module context where needed for allocation

Looks good to me, thanks!

@jsarha can you check CI on LNL. Lots of red.

Dropped volume module to a separate PR to understand the CI failures better: #10323

jsarha · 2025-10-23T13:48:41Z


 /* Allocate all FIR channels data in a big chunk and clear it */
- cd->fir_delay = rballoc(SOF_MEM_FLAG_USER, delay_size);
+ cd->fir_delay = mod_balloc(mod, delay_size);


This line will crash without this fix: #10324

 	ret = tdfb_ipc_notification_init(mod);
 	if (ret)
-goto err_free_cd;
+return ret;


same issue as in multiple other PRs

lyakh · 2025-10-27T10:57:20Z

- ret = -ENOMEM;
- goto cd_fail;
+ comp_err(dev, "mod_data_blob_handler_new() failed.");
+ return -ENOMEM;


potentially problematic too?

lyakh · 2025-10-27T10:58:10Z

+	cd->buf_in = mod_balloc(mod, mod->priv.cfg.base_cfg.ibs);
+	cd->buf_out = mod_balloc(mod, mod->priv.cfg.base_cfg.obs);
+	if (!cd->buf_in || !cd->buf_out)
+ return -ENOMEM;

These new versions of module conversions use module API to allocate the resources, but the code still has all the resource freeing code in place.

@softwarecki now done.
