Subject: Sun V880 + Infiniband?
Date: Wed, 2 Dec 2009 10:45:02 -0500 [thread overview]
Message-ID: <200912021045.02970.pat@computer-refuge.org> (raw)
So, I'm trying to get a Mellanox IB card to work on my Sun V880, and I'm
getting this error output to dmesg:
[ 99.529658] ib_mthca: Mellanox InfiniBand HCA driver v1.0 (April 4,
2008)
[ 99.609988] ib_mthca: Initializing 0003:01:00.0
[ 99.664180] PCI: Enabling device: (0003:01:00.0), cmd 2
[ 99.664193] ib_mthca 0003:01:00.0: Missing DCS, aborting.
I'm using a kernel compiled off of Linus's git tree as of a few days ago
(to fix other SPARC issues). From what I've seen from google searches,
this means that the first BAR isn't mapped or visible to the driver, so
maybe this is a SPARC related thing?
lspci -v output for the device:
