[S390] Kconfig: use common Kconfig files for s390.

2007-05-10T13:46:08+00:00

Disband drivers/s390/Kconfig, use the common Kconfig files. The s390 specific config options from drivers/s390/Kconfig are moved to the respective common Kconfig files. Signed-off-by: Martin Schwidefsky

[S390] Avoid sparse warnings.

2007-05-10T13:45:52+00:00

Monthly sparse warning avoidance patch. Sigh. Signed-off-by: Heiko Carstens

[S390] dasd: Fix modular build.

2007-05-10T13:45:52+00:00

Add missing export of dasd_generic_read_dev_chars(). Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky

[S390] cio: Get rid of _ccw_device_get_device_number().

2007-05-10T13:45:51+00:00

The function shouldn't have existed in the first place (not MSS-aware). Introduce a new function ccw_device_get_id() that extracts the ccw_dev_id structure of a ccw device and convert all users of _ccw_device_get_device_number to ccw_device_get_id.

[S390] dasd: New read device characteristics and read configuration data.

2007-05-04T16:48:26+00:00

Instead of the deprecated read_dev_chars() and read_conf_data_lpm(), implement dasd_generic_read_dev_chars() and dasd_eckd_read_conf_lpm(). These should even recover better from error than the original cio functions. Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky

[S390] dasd: Add ipldev parameter.

2007-04-27T14:01:44+00:00

Specifying 'ipldev' in the dasd= kernel parameter will automatically activate the boot device for use by the dasd driver. Signed-off-by: Peter Oberparleiter Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] dasd: Add sysfs attribute status and generate uevents.

2007-04-27T14:01:44+00:00

This patch adds a sysfs-attribute 'status' to make the DASD device-status accessible from user-space. In addition, the DASD driver generates an uevent(CHANGE) for the ccw-device on each device-status change. This enables user-space applications (e.g. udev) to do related processing.

[S390] dasd: Work around gcc bug.

2007-03-26T18:43:46+00:00

gcc incorrectly removes initialization of register 0 in dasd diag inline assembly. Use different register to work around this compiler bug. Cc: Martin Schwidefsky Signed-off-by: Peter Oberparleiter Signed-off-by: Heiko Carstens

[S390] dasd: Use default recovery for SNSS requests

2007-03-05T22:35:52+00:00

For extended error reporting we sometimes have to start an Sense Subsystem Status request (SNSS). When this request needs to be recovered for some reason, the recovery request will fail with 'command reject'. Our usual recovery procedure will retry the failed request by creating a new request and chaining the failed request from that one. SNSS requests, though, must not be chained from anything, so the recovery request will fail permanently. Use the default recovery for SNSS request, which will just restart the original request without further ado. Signed-off-by: Stefan Weinhuber Signed-off-by: Martin Schwidefsky
