From: Peter Ujfalusi Date: Thu, 2 Oct 2025 13:57:50 +0000 (+0300) Subject: ASoC: SOF: ipc4-topology: Correct the minimum host DMA buffer size X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a7fe5ff832d61d9393095bc3dd5f06f4af7da3c1;p=users%2Fhch%2Fmisc.git ASoC: SOF: ipc4-topology: Correct the minimum host DMA buffer size The firmware has changed the minimum host buffer size from 2 periods to 4 periods (1 period is 1ms) which was missed by the kernel side. Adjust the SOF_IPC4_MIN_DMA_BUFFER_SIZE to 4 ms to align with firmware.
