From 47593bfa1056d306fde067b28dd8617009be4121 Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Tue, 31 Mar 2009 19:16:05 +0200 Subject: [S390] cio: introduce notifier for boxed state If a ccw device did not respond in time during internal io, we set it into boxed state. With this patch we have the following behaviour: * the ccw driver will get a notification if the device was online and goes into the boxed state * if the device was disconnected and got boxed nothing special is to be done (it will be handled in reprobing later) * if the device got boxed while initial sensing it will be unregistered Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky --- arch/s390/include/asm/cio.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'arch/s390/include') diff --git a/arch/s390/include/asm/cio.h b/arch/s390/include/asm/cio.h index 6dccb071aec3..619bf94b11f1 100644 --- a/arch/s390/include/asm/cio.h +++ b/arch/s390/include/asm/cio.h @@ -456,6 +456,8 @@ struct ciw { #define CIO_OPER 0x0004 /* Sick revalidation of device. */ #define CIO_REVALIDATE 0x0008 +/* Device did not respond in time. */ +#define CIO_BOXED 0x0010 /** * struct ccw_dev_id - unique identifier for ccw devices -- cgit v1.2.3
