[S390] pm: dasd power management callbacks.

2009-06-16T08:31:10+00:00

Introduce the power management callbacks to the dasd driver. On suspend
the dasd devices are stopped and removed from the focus of alias
management.
On resume they are reinitialized by rereading the device characteristics
and adding the device to the alias management.
In case the device has gone away during suspend it will caught in the
suspend state with stopped flag set to UNRESUMED. After it appears again
the restore function is called again.

[S390] dasd: add High Performance FICON support

2009-03-26T14:24:05+00:00

To support High Performance FICON, the DASD device driver has to
translate I/O requests into the new transport mode control words (TCW)
instead of the traditional (command mode) CCW requests.

[S390] dasd: add device attribute to disable blocking on lost paths

2009-01-09T11:15:05+00:00

When the connection between host and storage server is lost, the
dasd device driver usually blocks all I/O on affected devices and
waits for them to reappear. In some setups however it would be
better if the I/O is returned as error so that device can be
recovered by some other means, eg. in a raid or multipath setup.

[S390] dasd: Add support for enhanced VM UID

2008-08-01T14:39:29+00:00

When z/VM provides two virtual devices (minidisks) that reside on the
same real device, both will receive the configuration data from the
real device and thus get the same uid. To fix this problem, z/VM
provides an additional configuration data record that allows to
distinguish between minidisks.
z/VM APAR VM64273 needs be installed so this fix has an effect.

[S390] dasd: Use const in busid functions.

2008-05-15T14:52:39+00:00

We should use 'const char *' in the busid functions since the
strings are not modified anyway.
