From 330d1deb410fe75f7f79bd1e5025f2827365eb83 Mon Sep 17 00:00:00 2001 From: Bard Liao Date: Tue, 3 Feb 2026 19:40:27 +0800 Subject: [PATCH] ASoC: SOF: Intel: hda-sdw-bpt: support simultaneous audio and BPT streams MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently the SoundWire BPT stream uses the paired link DMA but not reserve it. It works without any issue because we assume the SoundWire BPT will not run with audio streams simultaneously. To support simultaneous audio and BPT streams, we need to use the hda_dma_prepare/cleanup helpers to reserve the pair link host DMA.
