OFED in gentoo

Most recent HPC envirements usualy uses Infiniband hw. Today I moved full OFED stack from science overlay to main tree. So now gentoo support Infiniband and iWARP rdma devices out of the box =)

delta-force ~ # ibstatus
Infiniband device 'mlx4_0' port 1 status:
default gid: fe80:0000:0000:0000:001e:0bff:ff4c:7db9
base lid: 0x2
sm lid: 0x4
state: 4: ACTIVE
phys state: 5: LinkUp
rate: 20 Gb/sec (4X DDR)
link_layer: InfiniBand

Infiniband device 'mlx4_0' port 2 status:
default gid: fe80:0000:0000:0000:001e:0bff:ff4c:7dba
base lid: 0x0
sm lid: 0x0
state: 1: DOWN
phys state: 2: Polling
rate: 10 Gb/sec (4X)
link_layer: InfiniBand

PS: infiniband stuff lives under sys-infiniband category
PPS: seems in current time gentoo is only distro which support infiniband hw out of the box

    I tried emerging, and came up against libehca 1.2.2, I noted that there is an item in bugzilla that exactly describes what happened, but for 1.2.1.

    I wish I knew where to start… I’ll look at it and see if there is anything that jumps out at me.

    I checked with upstream, turns out that the libehca is for PowerPC only.
