2012-03-07lcs: Return zero from ccwgroup devs set_offline functionKlaus-Dieter Wacker1-5/+7
A return code of non-zero of the devs ccwgroup set_offline function leaves the dev in online state. Having done a partly offlining may leave the dev in unusable state. To make sure the dev is set to offline, zero is returned. A setup trace entry is written in case the offlining steps encountered some trouble.

2012-03-07ctcm: use correct idal word list for ctcmpcBelinda Thompson1-0/+11
Communication Server Linux uses the ctcmpc code of the ctcm driver. Sending problems have shown up caused by a wrong idal word list for the first ccw. Function ctcmpc_chx_txdone() invokes the function to prepare the idal word list without setting an appropriate length for the first ccw, which may lead to an incomplete idal word list. This patch sets the maximum buffer size as data length of the first ccw. Thus correct idal word lists are guaranteed in all cases.

To send commands on the write channel 8 buffers exist. If all 8 buffers are used, a wait is triggered on the write channel. When such buffer are freed, a wake_up is needed.

We've moving to a model where dst_entry objects to not have a reference to the associated neighbour entry, instead such neighbours must be looked up on-demand.

2012-01-24Driver core: driver_find() drops reference before returningAlan Stern1-5/+4
As part of the removal of get_driver()/put_driver(), this patch (as1510) changes driver_find(); it now drops the reference it acquires before returning. The patch also adjusts all the callers of driver_find() to remove the now unnecessary calls to put_driver(). In addition, the patch adds a warning to driver_find(): Callers must make sure the driver they are searching for does not get unloaded while they are using it. This has always been the case; driver_find() has never prevented a driver from being unregistered or unloaded. Hence the patch will not introduce any new bugs. The existing callers all seem to be okay in this respect, however I don't understand the video drivers well enough to be certain about them.

This patch extends the HiperSockets device driver to send and receive af_iucv traffic over HiperSockets transport. TX: Driver uses new asynchronous delivery of storage blocks to pass flow control/congestion information from the HiperSockets microcode to the af_iucv socket. RX: Memory for incoming traffic is preallocated and passed to HiperSockets layer. If receiver is not capable to clean its buffers shared with HiperSockets and pass new memory to the HiperSockets layer this will cause flow control/congestion events on the sender.

2011-08-13qeth: do not apply priority queuing to HiperSocketsUrsula Braun1-19/+21
OSA cards can be configured to support 1 or 4 output queues. This does not apply to HiperSockets. This patch limits determination of the configured number of output queues to OSA cards only, but excludes HiperSockets.

2011-06-06[S390] qdio: Split SBAL entry flagsJan Glauber2-28/+31
The qdio SBAL entry flag is made-up of four different values that are independent of one another. Some of the bits are reserved by the hardware and should not be changed by qdio. Currently all four values are overwritten since the SBAL entry flag is defined as an u32. Split the SBAL entry flag into four u8's as defined by the hardware and don't touch the reserved bits.
