From 8c12158687fc78091730d5456336b7efbf6f2250 Mon Sep 17 00:00:00 2001 From: Jaroslav Kysela Date: Fri, 11 Jan 2008 08:45:08 +0100 Subject: [ALSA] PCM interface - rename SNDRV_PCM_TSTAMP_MMAP to SNDRV_PCM_TSTAMP_ENABLE Change semantics for SNDRV_PCM_TSTAMP_MMAP. Doing timestamping only in the interrupt handler might cause that hw_ptr is not related to actual timestamp. With this change, grab timestamp at every hw_ptr update to have always valid timestamp + ring buffer position pair. With this change, SNDRV_PCM_TSTAMP_MMAP was renamed to SNDRV_PCM_TSTAMP_ENABLE. It's no regression (I think).
