From 08af495f22f43eff3b5a347dc10384ebcf356e41 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 3 Aug 2010 14:39:04 +0200 Subject: [PATCH] ALSA: hda - More relax for pending period handling Since the pending periods are often bogus and take long time until actually processed, it often results in a high CPU usage of the hd-audio workq. Overall it's better to have low CPU consumption by avoiding a too tight loop rather than the wake-up timing accuracy.
