IB/mthca: Initialize grh_present before using it · 9eacee2a

由 Michael S. Tsirkin 提交于 1月 12, 2006

build_mlx_header() was using sqp->ud_header.grh_present before it was
initialized by mthca_read_ah().  Furthermore, header->grh_present is
set by ib_ud_header_init, so there's no need to set it again in
mthca_read_ah().

IPoIB: Fix memory leak of multicast group structures · 988bd503

由 Eli Cohen 提交于 1月 12, 2006

The current handling of multicast groups in IPoIB ends up never
freeing send-only multicast groups.  It turns out the logic was much
more complicated than it needed to be; we can fix this bug and
completely kill ipoib_mcast_dev_down() at the same time.

IPoIB: Fix address handle refcounting for multicast groups · 97460df3

由 Eli Cohen 提交于 1月 10, 2006

Multiple ipoib_neigh structures on mcast->neigh_list may point to the
same ah. This means that ipoib_mcast_free() can't just make a list of
ah structs to free, since this might end up trying to add the same ah
to the list more than once. Handle this in ipoib_multicast.c in the
same way as it is handled in ipoib_main.c for struct ipoib_path.

IB: Add node_guid to struct ib_device · cf311cd4

由 Sean Hefty 提交于 1月 10, 2006

Add a node_guid field to struct ib_device. It is the responsibility
of the low-level driver to initialize this field before registering a
device with the midlayer. Convert everyone to looking at this field
instead of calling ib_query_device() when all they want is the node
GUID, and remove the node_guid field from struct ib_device_attr.

IB/mthca: prevent event queue overrun · 92898522

由 Michael S. Tsirkin 提交于 1月 09, 2006

I am seeing EQ overruns in SDP stress tests: if the CQ completion
handler arms a CQ, this could generate more EQEs, so that EQ will
never get empty and consumer index will never get updated.

This is similiar to what we have with command interface:
		/*
		 * cmd_event() may add more commands.
		 * The card will think the queue has overflowed if
		 * we don't tell it we've been processing events.
		 */
However, for completion events, we *don't* want to update the consumer
index on each event. So, perform EQ doorbell coalescing: allocate EQs
with some spare EQEs, and update once we run out of them.

The value 0x80 was selected to avoid any performance impact.
