Subject: [PATCH v2 2/5] xen: disable rtc_clock
Date: Fri, 27 Jan 2012 12:26:52 +0000 [thread overview]
Message-ID: <1327667215-5411-2-git-send-email-stefano.stabellini@eu.citrix.com> (raw)
In-Reply-To: <alpine.DEB.2.00.1201271211400.3196@kaball-desktop>
rtc_clock is only used by the RTC emulator (mc146818rtc.c), however Xen
has its own RTC emulator in the hypervisor so we can disable it.
