Push translation of static rate to HCA format into low-level drivers, where it belongs. For static rate encoding, use encoding of rate field from IB standard PathRecord, with addition of value 0, for backwards compatibility with current usage. The changes are: - Add enum ib_rate to midlayer includes. - Get rid of static rate translation in IPoIB; just use static rate directly from Path and MulticastGroup records. - Update mthca driver to translate absolute static rate into the format used by hardware. This also fixes mthca's static rate handling for HCAs that are capable of 4X DDR. Signed-off-by: NJack Morgenstein <jackm@mellanox.co.il> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

The in-kernel mthca driver contains a table of which attributes are valid for each queue pair state transition. It turns out that both other IB drivers -- ipath and ehca -- which are being prepared for merging have copied this table, errors and all. To forestall this code duplication, move this table and the code to check parameters against it into a midlayer library function, ib_modify_qp_is_ok().

This patch allows the consumer to set the page size of "pages" mapped by the pool FMRs, which is a feature already existing in the base verbs API. On the cosmetic side it changes ib_fmr_attr.page_size field to be named page_shift. Signed-off-by: NOr Gerlitz <ogerlitz@voltaire.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Expose a writable "node_desc" sysfs attribute for InfiniBand devices. This allows userspace to update the node description with information such as the node's hostname, so that IB network management software can tie its view to the real world.

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.

Change the struct ib_device.resize_cq() method to take a plain integer that holds the new CQ size, rather than a pointer to an integer that it uses to return the new size. This makes the interface match the exported ib_resize_cq() signature, and allows the low-level driver to update the CQ size with proper locking if necessary. No in-tree drivers are exporting this method yet. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

The MAD layer was violating the DMA API by touching data buffers used for sends after the DMA mapping was done. This causes problems on non-cache-coherent architectures, because the device doing DMA won't see updates to the payload buffers that exist only in the CPU cache. Fix this by having all MAD consumers use ib_create_send_mad() to allocate their send buffers, and moving the DMA mapping into the MAD layer so it can be done just before calling send (and after any modifications of the send buffer by the MAD layer). Tested on a non-cache-coherent PowerPC 440SPe system. Signed-off-by: NSean Hefty <sean.hefty@intel.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Al Viro pointed out that the current IB userspace verbs interface allows userspace to cause mischief by closing file descriptors before we're ready, or issuing the same command twice at the same time. This patch closes those races, and fixes other obvious problems such as a module reference leak. Some other interface bogosities will require an ABI change to fix properly, so I'm deferring those fixes until 2.6.15. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

First of a series of patches which add support for direct userspace access to InfiniBand hardware -- so-called "userspace verbs." I believe these patches are ready to merge, but a final review would be useful. These patches should incorporate all of the feedback from the discussion when I posted an earlier version back in April (see http://lkml.org/lkml/2005/4/4/267 for the start of the thread). In particular, memory pinned for use by userspace is accounted for in current->mm->vm_locked and requests to pin memory are checked against RLIMIT_MEMLOCK. This patch: Modify the ib_verbs.h header file with changes required for InfiniBand userspace verbs support. We add a few structures to keep track of userspace context, and extend the driver API so that low-level drivers know when they're creating resources that will be used from userspace.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
