From: Bard Liao Date: Tue, 3 Feb 2026 11:40:27 +0000 (+0800) Subject: ASoC: SOF: Intel: hda-sdw-bpt: support simultaneous audio and BPT streams X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=330d1deb410fe75f7f79bd1e5025f2827365eb83;p=thirdparty%2Fkernel%2Flinux.git ASoC: SOF: Intel: hda-sdw-bpt: support simultaneous audio and BPT streams 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.
