Date: Thu, 14 Jul 2022 09:10:39 +0800 From: Bard Liao <yung-chuan.liao@...ux.intel.com> To: alsa-devel@...a-project.org, vkoul@...nel.org Cc: vinod.koul@...aro.org, linux-kernel@...r.kernel.org, tiwai@...e.de, broonie@...nel.org, pierre-louis.bossart@...ux.intel.com, bard.liao@...el.com Subject: [PATCH 0/4] ASoC/soundwire: log actual PING status on resume issues we've been stuck with problems in the dual-amplifier configurations where one of the two devices seems to become UNATTACHED and never regains sync, see https://github.com/thesofproject/linux/issues/3638. This is a rather infrequent issue that may happen once or twice per month, but still it remains a concern. One possibility is that the device does lose sync but somehow our hardware detection fails to see it resync. This series just adds a basic read directly from the PING frames to help confirm if yes/no the device regain sync. The change is mainly on soundwire. @Mark, Could you ack the ASoC patch if it looks good to you?
