Serial can be disabled by a simple change: diff -r 2e5d4e459c1c buildconfigs/linux-defconfig_xen_ia64 --- a/buildconfigs/linux-defconfig_xen_ia64 Sun May 21 07:31:02 2006 -0600 +++ b/buildconfigs/linux-defconfig_xen_ia64 Mon May 22 15:06:00 2006 +0800 @@ -98,6 +98,7 @@ CONFIG_XEN_BLKDEV_FRONTEND=y CONFIG_XEN_BLKDEV_FRONTEND=y CONFIG_XEN_BACKEND=y CONFIG_XEN_BLKDEV_BACKEND=y +CONFIG_XEN_DISABLE_SERIAL=y CONFIG_XEN_SYSFS=y CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER=y CONFIG_DMA_IS_DMA32=y @@ -1544,4 +1545,3 @@ CONFIG_CRYPTO_DES=y # XEN # # CONFIG_XEN_UNPRIVILEGED_GUEST is not set -# CONFIG_XEN_DISABLE_SERIAL is not set
But I'm not sure why I have to set option to be 'yes' explicitly: config XEN_DISABLE_SERIAL bool "Disable serial port drivers" default y So after making oldconfig, this option should be enabled automatically. Does I misunderstand the logic behind? :-( Thanks, Kevin >-----Original Message----- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] On Behalf Of >Tian, Kevin >Sent: 2006年5月22日 14:53 >To: Isaku Yamahata >Cc: xen-ia64-devel@lists.xensource.com >Subject: RE: [Xen-ia64-devel] [PATCH 0/6] Add full evtchn mechanism >forxen/ia64 > >>From: Isaku Yamahata [mailto:[EMAIL PROTECTED] >>Sent: 2006年5月22日 13:43 >>On Mon, May 22, 2006 at 12:53:11PM +0800, Tian, Kevin wrote: >> >>> Why is serial >>> required to be disabled in dom0?
