[PATCH] s390: 64 bit diag250 support

2005-09-05T07:06:27+00:00

Add support for diag 250 access to dasd devices for 64 bit kernels.  In
addition fix detach/attach for diag disks.  The VM control block needs to get
recreated by a call to mdsk_init_io.

[PATCH] s390: deadlock in dasd_devmap

2005-09-05T07:06:26+00:00

Reintroduce a read-only copy of the devmap features in the device struct.
This is necessary to solve a deadlock on the dasd_devmap_lock which is
acquired by dasd_get_features called from the dasd tasklet.  The current
implementation of devmap doesn't allow to call any devmap function from
interrupt or softirq context.

[PATCH] s390: fba dasd i/o errors

2005-07-27T23:26:05+00:00

The FBA discipline does not use retries for failed requests.  A request fails
after the first unsuccessful start attempt.  There are some rare conditions
(e.g.  CIO path recovery) in which the start of an i/o on a fba device can
fail.  A tiny amount of retries is therefore reasonable.

[PATCH] s390: debug feature changes

2005-06-25T23:24:37+00:00

This patch changes the memory allocation method for the s390 debug feature.
Trace buffers had been allocated using the get_free_pages() function before.
Therefore it was not possible to get big memory areas in a running system due
to memory fragmentation.  Now the trace buffers are subdivided into several
subbuffers with pagesize.  Therefore it is now possible to allocate more
memory for the trace buffers and more trace records can be written.

In addition to that, dynamic specification of the size of the trace buffers is
implemented.  It is now possible to change the size of a trace buffer using a
new debugfs file instance.  When writing a number into this file, the trace
buffer size is changed to 'number * pagesize'.

In the past all the traces could be obtained from userspace by accessing files
in the "proc" filesystem.  Now with debugfs we have a new filesystem which
should be used for debugging purposes.  This patch moves the debug feature
from procfs to debugfs.

Since the interface of debug_register() changed, all device drivers, which use
the debug feature had to be adjusted.

[PATCH] s390: dasd set online failure

2005-05-17T14:59:17+00:00

dasd driver changes:
 - The feature check in dasd_generic_online returns an error if
   the devmap entry for the device is not yet available. Check
   for the feature after the device has been created.
 - Do symmetric registration/deregistration of cdev->handler.
