* [S390] cio: use pim to check for multipath.Sebastian Ott2008-12-251-1/+2
| | | | | | | | | | | To check if multipath is available we count the bits set in lpm, which could change over time (via configure [on|off] of a path). The following patch uses the pim (which is persistent) for this decision. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] cio: commit all pmcw changes.Sebastian Ott2008-12-251-0/+6
| | | | | | | | | | Sometimes we change the pmcw configuration but don't call msch to transmit these changes to the channel subsystem. The patch fixes this by calling cio_commit_config in such cases.

* [S390] cio: introduce cio_commit_configSebastian Ott2008-12-251-18/+18
| | | | | | | | | | | | | | | | | | | To change the configuration of a subchannel we alter the modifiable bits of the subchannel's schib field and issue a modify subchannel. There can be the case that not all changes were applied -or worse- quietly overwritten by the hardware. With the next store subchannel we obtain the current state of the hardware but lose our target configuration. With this patch we introduce a subchannel_config structure which contains the target subchannel configuration. Additionally the msch wrapper cio_modify is replaced with cio_commit_config which copies the desired changes to a temporary schib. msch is then called with the temporary schib. This schib is only written back to the subchannel if all changes were applied. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] cio: introduce cio_update_schibSebastian Ott2008-12-251-9/+4
| | | | | | | | | | | | | | | | | | | | | There is the chance that we get condition code 0 for a stsch but the resulting schib is not vaild. In the current code there are 2 cases: * we do a check for validity of the schib after stsch, but at this time we have already stored the invaild schib in the subchannel structure. This may lead to problems. * we don't do a check for validity, which is not that good either. The patch addresses both issues by introducing the stsch wrapper cio_update_schib which performs stsch on a local schib. This schib is only written back to the subchannel if it's valid. side note: For some functions (chp_events) the return codes are different now (-ENXIO vs -ENODEV) but this shouldn't do harm since the caller doesn't check for _specific_ errors.

| | | | | | | | | | If we fail the probe for an I/O subchannel, we won't be able to unregister it again since there are no sch_event() callbacks for unbound subchannels.

* [S390] cio: Only register ccw_device for registered subchannel.Cornelia Huck2008-12-251-6/+12
| | | | | | | | | | | | There is a race between io_subchannel_register() and io_subchannel_sch_event() which may cause a subchannel to be unregistered because it is no longer operational before io_subchannel_register() had run. We need to check whether the subchannel is still registered before the ccw device can be registered and just bail out if it is not.

* [S390] cio: Fix I/O subchannel refcounting.Cornelia Huck2008-12-251-19/+56
| | | | | | | | | | | | | | | | | | | | | Subchannel refcounting was incorrect in some places, especially a refcount was missing when ccw_device_call_sch_unregister() was called and the refcount was not correctly switched after moving devices. Fix this by establishing the following rules: - The ccw_device obtains a reference on its parent subchannel when dev.parent is set and gives it up in its release function. This is needed because we need a parent reference for correct refcounting even before the ccw device is (if at all) registered. - When calling device_move(), obtain a reference on the new subchannel before moving the ccw device and give up the reference on the old parent after moving. This brings the refcount in line with the first rule. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] cio: Fix reference counting for online/offline.Cornelia Huck2008-12-251-7/+22
| | | | | | | | | | | | | | | | | | | | | | The current code attempts to get an extra reference count for online devices by doing a get_device() in ccw_device_online() and a put_device() in ccw_device_done(). However, this - incorrectly obtains an extra reference for disconnected devices becoming available again (since they are already online) - needs special checks for css_init_done in order to handle the console device - is not obvious and - may incorretly drop a reference count in ccw_device_done() if that function is called after path verification for a device that just became not operational. So let's just get the reference in ccw_device_set_online() and drop it in ccw_device_set_offline(). (Unfortunately, we still need the special case in io_subchannel_probe().)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was the possibilty that an action like ccw_device_set_offline() triggered by a device gone machine check might trigger a not oper event. Unfortunately, this could lead to the situation that we tried to unregister a subchannel twice: Once from the slow path evaluation, and once via the not oper event. Fix this by always using the same mechanism (css_schedule_eval()) for triggering the unregister. This makes sure that unregistration will only be done once.
