Subject: [Qemu-devel] [PATCH 1/4] audio: Lower default wakeup rate to 100 times / second
Date: Mon, 9 Dec 2013 15:06:11 +0100 [thread overview]
Message-ID: <1386597974-26506-2-git-send-email-kraxel@redhat.com> (raw)
In-Reply-To: <1386597974-26506-1-git-send-email-kraxel@redhat.com>
From: Hans de Goede <hdegoede@redhat.com>
This is more then plenty to keep audio card fifos filles / emptied.
This drops host cpu-load for audio playback inside a linux vm from
13% to 9%.
