From f9eeb6bb13fb5d7af1ea5b74a10b1f8ead962540 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 21 Mar 2024 15:08:13 +0200 Subject: [PATCH] ALSA: hda: Add pplcllpl/u members to hdac_ext_stream The pplcllpl/u can be used to save the Link Connection Linear Link Position register value to be used for compensation of the LLP register value in case the counter is not reset (after pause/resume or stop/start without closing the stream). The LLP can be used along with PPHCLDP to calculate delay caused by the DSP processing for HDA links.
