[ANNOUNCE] libmthca 1.0.5 and libmlx4 1.0.2 are released

[Roland Dreier]

libmthca and libmlx4 are userspace drivers for Mellanox InfiniBand
HCAs.  They are plug-in modules for libibverbs that allows programs to
use Mellanox hardware directly from userspace.

New stable releases are available from

    http://www.openfabrics.org/downloads/mthca/libmthca-1.0.6.tar.gz
    http://www.openfabrics.org/downloads/mlx4/libmlx4-1.0.2.tar.gz

with sha1sum

    156d90ea343a18fd638c0097ea8d2e97af3f6e25  libmthca-1.0.6.tar.gz
    8c5e9deb47b6a3f0163fa5e85ea7560451c4a09b  libmlx4-1.0.2.tar.gz

I also pushed the latest trees and tags out to kernel.org:

    git://git.kernel.org/pub/scm/libs/infiniband/libmthca.git
    git://git.kernel.org/pub/scm/libs/infiniband/libmlx4.git

(the name of the tags are libmthca-1.0.6 and libmlx4-1.0.2)

These releases contain a variety of accumulated small fixes since the
previous long-ago releases.

The git shortlog since libmthca 1.0.5 is:

Jack Morgenstein (1):
      Fix race between create QP and destroy QP

Jason Gunthorpe (2):

      Update Debian policy version to 3.8.2
      Package description shouldn't start with an article

      Convert to new 3.0 (quilt) source format.
      Change Debian build system from cdbs to debhelper 7
      Move plugin .so to /usr/lib/libibverbs
      Revert "Update build system to use shave"
      Enable quiet build rules with automake 1.11+
      Small configure.in modernizations

      Note that we fix Debian bug about maintainer address in Debian changelog
      Roll libmthca 1.0.6 release

Sebastien Dugue (1):
      Use mmap(MAP_ANONYMOUS) to allocate queue buffers


The git shortlog since libmlx4 1.0.1 is:

Jack Morgenstein (1):
      Initialize SRQ scatter entries when creating an SRQ

Roland

What about the new CX3 device ID patch?
Also - when will the RoCE user space patches be included in the library?

Thanks

Did I ever get a final version of the libmthca and kernel patches?

> Also - when will the RoCE user space patches be included in the library?

That's probably the next thing for libibverbs.

CX3 is using libmlx4 and not libmthca.
Vlad sent a patch on 1/19/11:
http://www.spinics.net/lists/linux-rdma/msg07237.html


Is contain adding several device IDs including CX3

Do you wish separate patch on each device?

Why is that test even in libmlx4?

Maybe this is a better choice:

We need some way for userspace drivers to know which devices to bind.

Sorry, I meant libmlx4 of course.

So that patch includes

+	HCA(MELLANOX, 0x6778),	/* MT26488 [ConnectX VPI PCIe 2.0 5GT/s - IB
DDR / 10GigE Virt+] */

which the kernel seems to be missing.  Should it be there?

That's why I ask about final patches that bring kernel and libmlx4
into sync, someone needs to check both device lists.

Hum, for some reason I thought it was already keying off the sysfs
driver entry:

$ readlink class/infiniband_verbs/uverbs0/device/driver
../../../../bus/pci/drivers/mlx4_core
