[S390] dasd: Add ipldev parameter.

2007-04-27T14:01:44Z

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.

2007-04-27T14:01:44Z

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] New DASD feature for ERP related logging

2006-12-08T14:54:15Z

It is now possible to enable/disable ERP related logging without re-compile and re-ipl. A additional sysfs-attribute 'erplog' allows to switch the logging non-interruptive. Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky

[PATCH] slab: remove kmem_cache_t

2006-12-07T16:39:25Z

Replace all uses of kmem_cache_t with struct kmem_cache. The patch was generated using the following script: #!/bin/sh # # Replace one string by another in all the kernel sources. # set -e for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do quilt add $file sed -e "1,\$s/$1/$2/g" $file >/tmp/$$ mv /tmp/$$ $file quilt refresh done The script was run like this sh replace kmem_cache_t "struct kmem_cache" Signed-off-by: Christoph Lameter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[S390] return 'count' for successful execution of dasd_eer_enable.

2006-12-04T14:40:18Z

Currently the return value of 'dasd_eer_enable' is returned - even if the function returned '0'. Now return 'count' for successful execution. Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky

[S390] handle incorrect values when writing to dasd sysfs attributes.

2006-12-04T14:39:50Z

When writing to dasd attributes (e.g. readonly), all values besides '1' are handled like '0'. Other sysfs-attributes like 'online' are checking for '1' and for '0' and do not accept other values. Therefore enhanced checking and error handling in dasd_devmap attribute store functions. Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky

[S390] Replace nopav-message on VM.

2006-09-20T13:59:52Z

Specifying kernel parameter "dasd=nopav" on systems running under VM has no function but results in message "disable PAV mode". Correct message is "'nopav' not supported on VM". Signed-off-by: Peter Oberparleiter Signed-off-by: Martin Schwidefsky

[S390] dasd deadlock after state change pending interrupt.

2006-09-20T13:59:05Z

The dasd_device_from_cdev function is called from interrupt context to get the struct dasd_device associated with a ccw device. The driver_data of the ccw device points to the dasd_devmap structure which contains the pointer to the dasd_device structure. The lock that protects the dasd_devmap structure is acquire with out irqsave. To prevent the deadlock in dasd_device_from_cdev if it is called from interrupt context the dependency to the dasd_devmap structure needs to be removed. Let the driver_data of the ccw device point to the dasd_device structure directly and use the ccw device lock to protect the access. Signed-off-by: Martin Schwidefsky

[S390] dasd PAV enabling.

2006-08-24T11:22:36Z

The subsystem check in the PAV code is incorrect, it enables PAV per device instead of per subsystem. Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky
