Prior to this change tstamp was not updated by snd_pcm_update_hw_ptr0() unless the hw_ptr had moved, after this change tstamp was always updated. For an application using alsa-lib, doing snd_pcm_readi() followed by snd_pcm_status() to estimate the age of the read samples by subtracting status->avail * [sample rate] from status->tstamp this change degraded the accuracy of the estimate on devices where the pcm hw does not provide a granular hw_ptr, e.g., devices using soc-generic-dmaengine-pcm.c and a dma-engine with residue_granularity DMA_RESIDUE_GRANULARITY_DESCRIPTOR. The accuracy of the estimate depended on the latency between the PCM hw completing a period and the driver called snd_pcm_period_elapsed() to notify ALSA core, typically determined by interrupt handling latency. After the change the accuracy of the estimate depended on the latency between the PCM hw completing a period and the application calling snd_pcm_status(), determined by the scheduling of the application process. The maximum error of the estimate is one period length in both cases, but the error average and variance is smaller when it depends on interrupt latency. Instead of always updating tstamp, update it only if audio_tstamp changed.

[Linux-stable-mirror] Patch "ALSA: hda - Fix yet remaining issue with vmaster 0dB initialization" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ALSA: hda - Fix yet remaining issue with vmaster 0dB initialization to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: alsa-hda-fix-yet-remaining-issue-with-vmaster-0db-initialization.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From d6c0615f510bc1ee26cfb2b9a3343ac99b9c46fb Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai(a)suse.de> Date: Wed, 22 Nov 2017 12:34:56 +0100 Subject: ALSA: hda - Fix yet remaining issue with vmaster 0dB initialization From: Takashi Iwai <tiwai(a)suse.de> commit d6c0615f510bc1ee26cfb2b9a3343ac99b9c46fb upstream. The previous fix for addressing the breakage in vmaster slave initialization, commit a91d66129fb9 ("ALSA: hda - Fix incorrect TLV callback check introduced during set_fs() removal"), introduced a new helper to process over each slave kctl. However, this helper passes only the original kctl, not the virtual slave kctl. As a result, HD-audio driver (which is the only user so far) couldn't initialize the slave correctly because it's trying to update the value directly with the original kctl, not with the mapped kctl. This patch fixes the situation again by passing both the mapped slaved and original slave kctls to the function. Luckily there is a single caller as of now, so changing the call signature is no big matter.
