Subject[git pull] InfiniBand updates for 2.6.14
From
Date
Linus, please pull from

rsync://rsync.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git

The only thing slightly noteworthy in this tree is the commit that
moves the InfiniBand midlayer includes from drivers/infiniband/include
to include/rdma. However, this was discussed in the thread starting
with <http://lkml.org/lkml/2005/8/4/191> and no objections were raised.

Pulling will update the following files:

[PATCH] IB: move include files to include/rdma

Move the InfiniBand headers from drivers/infiniband/include to include/rdma.
This allows InfiniBand-using code to live elsewhere, and lets us remove the
ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles.

[PATCH] IPoIB: Fix device removal race

Currently we may have work scheduled in default kernel workqueue when
the device is going down. The device could get freed before this
workqueue gets serviced. I am actually seeing this causing system
hangs.

The following patch fixes this by using ipoib_workqueue which gets
flushed when the device is going down.

[PATCH] IPoIB: Set full membership bit in P_Keys

Always make sure that the full membership bit is set in the P_Keys
that IPoIB uses. This makes sure that all hosts join the correct
multicast groups so that hosts that are partial partition members
can talk to the rest of the network.

[PATCH] IB/mthca: Handle context tables smaller than our chunk size

When creating a table in context memory where the table is smaller
than our chunk size, we don't want to allocate and map a full chunk.
Instead, allocate just enough memory to cover the table.

This can be pretty simple because all tables are a power-of-2 size, so
either the table is a multiple of the chunk size, or it's smaller than
one chunk.

[PATCH] IB/mthca: Simplify handling of completions with error

Mem-free HCAs never generate error CQEs that complete multiple WQEs,
so just skip the call to mthca_free_err_wqe() for them rather than
having logic to handle the mem-free case in mthca_free_err_wqe().

[PATCH] IB/mthca: Factor out common queue alloc code

Clean up the allocation of memory for queues by factoring out the
common code into mthca_buf_alloc() and mthca_buf_free(). Now CQs and
QPs share the same queue allocation code, which we'll also use for SRQs.

[PATCH] IB: userspace SRQ support

Add SRQ support to userspace verbs module. This adds several commands
and associated structures, but it's OK to do this without bumping the
ABI version because the commands are added at the end of the list so
they don't change the existing numbering. There are two cases to
worry about:

1. New kernel, old userspace. This is OK because old userspace simply
won't try to use the new SRQ commands. None of the old commands are
changed.

2. Old kernel, new userspace. This works perfectly as long as
userspace doesn't try to use SRQ commands. If userspace tries to
use SRQ commands, it will get EINVAL, which is perfectly
reasonable: the kernel doesn't support SRQs, so we couldn't do any
better.

[PATCH] IB/mthca: Use correct port width capability value

When we call the INIT_IB firmware command to bring up a port, use
the actual port width capability returned by the QUERY_DEV_LIM
command instead of always trying to enable both 1X and 4X. This
fixes breakage seen when the firmware is build to allow 4X only.
