I nuked several static variables. we have -static void fbcon_vbl_handler(int irq, void *dummy, struct pt_regs *fp) +static void fb_vbl_handler(int irq, void *dev_id, struct pt_regs *fp) and 3 years later a couple of instances missed back then still remains there.

iommu_init() and iounit_init() are never called for sun4, but that's not enough - these calls should be ifdefed out since the functions in question simply do not exist for CONFIG_SUN4 kernel. Signed-off-by:

Back when pci_dev had base_address[], loop of form base = &...->base_address[0]; for (.....) { ... *base++ = addr; } was fine, but when that array got spread in ->resource[...].start replacing the initialization with base = &...->resource[0].start; was not a sufficient modification. IOW this code got broken for cases when there had been more than one resource to fill. All way back in 2.3.41-pre3... Signed-off-by: -

When ipoib_ib_dev_flush() is called because of a port event, the driver needs to rejoin all multicast groups, since the flush will call ipoib_mcast_dev_flush() (via ipoib_ib_dev_down()). Otherwise no (non-broadcast) multicast groups will be rejoined until the networking core calls ->set_multicast_list again, and so multicast reception will be broken for potentially a long time.

RFC 4391 ("Transmission of IP over InfiniBand (IPoIB)") says: If the IB multicast group does not already exist, one must be created first with the IPoIB link MTU. The MGID MUST use the same P_Key, Q_Key, SL, MTU, and HopLimit as those used in the broadcast-GID. The rest of attributes SHOULD follow the values used in the broadcast-GID as well. However, the current IPoIB driver is only setting the attributes required by the InfiniBand spec to create a multicast group, so in particular the MTU and HopLimit are not being set. Add these attributes when creating MCGs, and also set the Rate attribute, since IPoIB pays attention to that attribute as well. Signed-off-by: -

If a QP has separate send and receive CQs, then the send CQ will never have receive completions from that QP in it. So when cleaning the send CQ, there's no need to pass in an SRQ pointer, even if the QP is attached to an SRQ. Signed-off-by: -

Trigger device remove and then add when a catastrophic error is detected in hardware. This, in turn, will cause a device reset, which we hope will recover from the catastrophic condition. Since this might interefere with debugging the root cause, add a module option to suppress this behaviour. Signed-off-by:

Fast Memory Registration (fmr) is used to register for rdma an sg whose elements are not linearly sequential after dma mapping. The IB verbs layer provides an "all dma memory MR (memory region)" which can be used for RDMA-ing a dma linearly sequential buffer. Change the code to use the dma mr instead of doing fmr when dma mapping produces a single dma entry sg. Signed-off-by:

fix and add some debug prints related to iser handling of memory for rdma. Signed-off-by:
-
Erez Zilber authored
As iser is able to use at most one rdma operation for the execution of a scsi command, and registration of the sg associated with scsi command has its restrictions, the code checks if an sg is "aligned for rdma". Alignment for rdma is measured in "fmr page" units whose possible resolutions are different between HCAs and can be smaller, equal or bigger to the system page size. When the system page size is bigger than 4KB (eg the default with ia64 kernels) there a bigger chance that an sg would be aligned for rdma if the fmr page size is 4KB. Change the code to create FMR whose pages are of size 4KB and to take that into account when processing the sg. Signed-off-by:

Currently, the data length of a command coming down from scsi-ml is limited only by the size of its sg list (sg_tablesize). The max data length may be different for different page size values. By setting max_sectors, we limit the data length to max_sectors*512 bytes. Signed-off-by:

dma mapping may include a "compaction" of the sg associated with scsi command. Hence, the size of the maximal prefix of the SG which is aligned for rdma must be compared against the length of the dma mapped sg (mem->dma_nents) and not against the size of it before it was mapped (mem->size).

Add an iWARP Connection Manager (CM), which abstracts connection management for iWARP devices (RNICs). It is a logical instance of the xx_cm where xx is the transport type (ib or iw).

The implementation assumes that any RMPP request that requires a response uses DS RMPP. Based on the RMPP start-up scenarios defined by the spec, this should be a valid assumption. That is, there is no start-up scenario defined where an RMPP request is followed by a non-RMPP response. By having this assumption we avoid any API changes. In order for a node that supports DS RMPP to communicate with one that does not, RMPP responses assume a new window size of 1 if a DS ACK has not been received. (By DS ACK, I'm referring to the turn-around ACK after the final ACK of the request.) This is a slight spec deviation, but is necessary to allow communication with nodes that do not generate the DS ACK. It also handles the case when a response is sent after the request state has been discarded. Signed-off-by:
