From b0f3235f37e9cb6abd2527cf42bec94f6fa6718f Mon Sep 17 00:00:00 2001 From: Uday M Bhat Date: Mon, 23 Feb 2026 09:43:20 +0530 Subject: [PATCH] topology2: tplg-targets-sdca-generic: remove 10ms deep buffer dma buffer With Dynamic DeepBuffer the host DMA buffer size is calculated based on the requested ALSA period size (with a headroom between the two) using the DEEP_BUFFER token as a maximum limit for the host DMA buffer. This way applications can use the same DeepBuffer enabled PCM for different use cases and still benefit of the power saving of a bigger host DMA Kernel has been updated https://github.com/thesofproject/linux/pull/5673 Signed-off-by: Uday M Bhat --- .../topology2/production/tplg-targets-sdca-generic.cmake | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/tools/topology/topology2/production/tplg-targets-sdca-generic.cmake b/tools/topology/topology2/production/tplg-targets-sdca-generic.cmake index fe393b3d2769..5327b23aaf4e 100644 --- a/tools/topology/topology2/production/tplg-targets-sdca-generic.cmake +++ b/tools/topology/topology2/production/tplg-targets-sdca-generic.cmake @@ -13,19 +13,19 @@ SDW_JACK_IN_STREAM=Capture-SimpleJack,NUM_HDMIS=0" "cavs-sdw\;sof-sdca-1amp-id2\;NUM_SDW_AMP_LINKS=1,SDW_JACK=false,\ SDW_AMP_FEEDBACK=false,SDW_SPK_STREAM=Playback-SmartAmp,NUM_HDMIS=0,\ -DEEPBUFFER_FW_DMA_MS=10,DEEP_BUF_SPK=true" +DEEP_BUF_SPK=true" "cavs-sdw\;sof-sdca-2amp-id2\;NUM_SDW_AMP_LINKS=2,SDW_JACK=false,\ SDW_AMP_FEEDBACK=false,SDW_SPK_STREAM=Playback-SmartAmp,NUM_HDMIS=0,\ -DEEPBUFFER_FW_DMA_MS=10,DEEP_BUF_SPK=true" +DEEP_BUF_SPK=true" "cavs-sdw\;sof-sdca-3amp-id2\;NUM_SDW_AMP_LINKS=3,SDW_JACK=false,\ SDW_AMP_FEEDBACK=false,SDW_SPK_STREAM=Playback-SmartAmp,NUM_HDMIS=0,\ -DEEPBUFFER_FW_DMA_MS=10,DEEP_BUF_SPK=true" +DEEP_BUF_SPK=true" "cavs-sdw\;sof-sdca-4amp-id2\;NUM_SDW_AMP_LINKS=4,SDW_JACK=false,\ SDW_AMP_FEEDBACK=false,SDW_SPK_STREAM=Playback-SmartAmp,NUM_HDMIS=0,\ -DEEPBUFFER_FW_DMA_MS=10,DEEP_BUF_SPK=true" +DEEP_BUF_SPK=true" "cavs-sdw\;sof-sdca-mic-id4\;SDW_JACK=false,SDW_DMIC=1,NUM_HDMIS=0,\ SDW_DMIC_STREAM=Capture-SmartMic"
