The ibmebus_free_irq() function, which might sleep, was called with
interrupts disabled. To ship around this, make sure that no interrupts
are running by killing the interrupt tasklet. Also lock the shca_list_lock to
protect against the poll_eqs_timer running concurrently.

hello,
is it possible to add a patch in ofed release for non-ib networks? we've
integrated ofed with 'paramnet-3' a 10Gbps system area network. currently
IPoIB is working fine. more details can be provided if required.
thanks for your time.

Hello,
It seems ib_post_send() is implemented slightly differently in the
various hardware drivers (as in kernel 2.6.31). Here are the differences
I've noticed regarding the bad_wr parameter.
amso1100/c2_qp.c : c2_post_send()
* bails out and does not set bad_wr if the 1st check is bad.

This patch series adds a new routing engine designed to handle large
fabrics connected with a 2D/3D torus topology.
Patches 1-4 do some preparation to handle new SL-related features of
the routing engine, patches 5/6 add and enable the engine, and patches
7-11 have some fixups that only make
A routing engine that wants to make contributions to SL2VL maps in support
of routing free from credit loops may need to know the minimum number
of supported data VLs in the fabric.
This code tracks that value.

LASH already does this, in a hard-coded fashion.
Generalize this by adding a callback to struct osm_routing_engine that
computes a path SL value, and fix up LASH to use it.
This patchset causes the requested or QoS-computed SL value to be passed
to the routing engine path SL computation as a

In the event a routing engine needs to participate in SL assignment and
SL2VL map setup in order to avoid credit loops in a fabric, it will be
useful to make the routing engine context more widely available.
To this end, have osm_opensm_t save a pointer to the routing engine used,
rather than its
The torus-2QoS engine provides a deadlock-free routing for a 2D/3D torus,
but requires that switch SL2VL maps be programmed. Before this change,
opensm -Q was required for that to happen.
When a routing engine sets the struct osm_routing_engine:update_sl2vl
pointer, it is signalling its intent

Torus-2QoS makes persistent use of osm_port_t:priv to speed calculation
of path SL values.
It cannot clear osm_port_t:priv members when it tears down its persistent

I've attached the patch as a compressed file, as otherwise
it is too large to make it through the list.

The attached files can be used to test the torus-2QoS routing
engine using ibsim.
fabric-torus-5x5x5 contains a fabric description that ibsim can read.
Once ibsim is running, run opensm like this:
opensm --config opensm.conf --torus_config torus-2QoS-5x5x5.conf
or
opensm --config
