This patch implements config_changed for the s390 virtio transport.
We use the least significant bit of the interrupt parameter field
to decide, if this interrupt should call the virtio virtqueue callback
or the config_changed callback.This method is compatible with old host and guest code. Old 64 bit guests
will not check the bit and trigger a harmless additional vring_interrupt
call. Old host code will never set this bit, this is also safe.This patch also takes care of a potential future 31 bit virtio transport
for s390. On 31 bit _LC_PFAULT_INTPARM and __LC_EXT_PARAMS are identical.
We exploit the alignment of the token and fold the change bit into the
lsb of the token itself.Signed-off-by: Christian Borntraeger

This allows each virtio user to hand in the alignment appropriate to
their virtio_ring structures.Signed-off-by: Rusty Russell

This doesn't really matter, since s390 pagesize is 4k anyway.

Remove a message that was emitted for a port that could not initially
be opened. This is a rare case when the port discovery hits an
initiator port and only confuses the user with an initator port logged
in the message. Remove the whole special case: The failed "open port"
request triggers required follow-up actions anyway.Signed-off-by: Christof Schmitt

Add the support to send CT and ELS requests as unchained FSF requests. This is
required for older hardware and was somehow omitted during the cleanup of the
FSF layer. The req_count and resp_count attributes are unused, so remove them
instead of adding a special case for setting them. Also add debug data and a
warning, when the ct request hits a limit.Signed-off-by: Christof Schmitt

With the change to the dev_ message macros, the macro to get the busid

The port flag DID_DID indicates whether we know the current id of the
port. This is always set in parallel. Since the id 0 is invalid
(because the port id 0 is invalid) we can remove the DID_DID flag:
d_id of 0 indicates an invalid d_id != 0 is a valid one.Signed-off-by: Christof Schmitt

The information from the kernel parameter is only needed during init.
Keep the three pieces (busid, wwpn and lun) local to simplify the

After the latest changes, the list of FCP devices is only used to
lookup the adapter for requests from the actcli tool. Change this to
use the lookup function in the cio layer. Now we can remove the
adapter list and have one place less to use the global config_lock.Signed-off-by: Christof Schmitt

To check if multipath is available we count the bits set in lpm,

decision.Signed-off-by: Sebastian Ott

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.
Signed-off-by: Sebastian Ott
Signed-off-by: Martin Schwidefsky -
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
Signed-off-by: Martin Schwidefsky -
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.Signed-off-by: Sebastian Ott
