From 9d92a7e1b0d095c8be96ce5e592c6c5541684631 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Mon, 14 Jul 2008 09:59:05 +0200 Subject: [S390] cio: Add chsc subchannel driver. This patch adds a driver for subchannels of type chsc. A device /dev/chsc is created which may be used to issue ioctls to: - obtain information about the machine's I/O configuration - dynamically change the machine's I/O configuration via asynchronous chsc commands Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens --- include/asm-s390/isc.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/asm-s390/isc.h') diff --git a/include/asm-s390/isc.h b/include/asm-s390/isc.h index fe56f7b445ea..34bb8916db4f 100644 --- a/include/asm-s390/isc.h +++ b/include/asm-s390/isc.h @@ -14,6 +14,7 @@ /* Regular I/O interrupts. */ #define IO_SCH_ISC 3 /* regular I/O subchannels */ #define CONSOLE_ISC 1 /* console I/O subchannel */ +#define CHSC_SCH_ISC 7 /* CHSC subchannels */ /* Adapter interrupts. */ #define QDIO_AIRQ_ISC IO_SCH_ISC /* I/O subchannel in qdio mode */ -- cgit v1.2.3-55-g7522
