AMD-Pensando Ionic RDMA Driver Added To Linux 6.18, Intel IPU E2000 Hardware Too

([Linux Networking] 5 Hours Ago RDMA)


The past several months has seen [1]AMD engineers working on a new RDMA driver for Ionic hardware through which they [2]acquired Pensando a few years ago. That AMD-Pensando Ionic RDMA driver is now part of the upstream Linux 6.18 kernel.

The new "ionic" RDMA driver supports the AMD Pensando Ethernet device with Remote Direct Memory Access capabilities. Merged way back in 2019 was [3]an original Pensando driver for Linux in supporting the company's original network hardware.

Since AMD's acquisition more Pensando IP/hardware has been enabled in the mainline Linux kernel such as the [4]Elba SoC and more for helping to bolster AMD's data center ambitions.

Over on the Intel side, the RDMA pull for Linux 6.18 includes IRDMA "GEN3" hardware support. This "GEN3" hardware support is for RDMA RoCEv2 with the IPU E2000 product line.

More details on these changes and the other RDMA happenings for Linux 6.18 via [5]this pull request , which has since been merged to Linux Git.

A feed salesman is on his way to a farm. As he's driving along at forty
m.p.h., he looks out his car window and sees a three-legged chicken running
alongside him, keeping pace with his car. He is amazed that a chicken is
running at forty m.p.h. So he speeds up to forty-five, fifty, then sixty
m.p.h. The chicken keeps right up with him the whole way, then suddenly
takes off and disappears into the distance.
The man pulls into the farmyard and says to the farmer, "You know,
the strangest thing just happened to me; I was driving along at at least
sixty miles an hour and a chicken passed me like I was standing still!"
"Yeah," the farmer replies, "that chicken was ours. You see, there's
me, and there's Ma, and there's our son Billy. Whenever we had chicken for
dinner, we would all want a drumstick, so we'd have to kill two chickens.
So we decided to try and breed a three-legged chicken so each of us could
have a drumstick."
"How do they taste?" said the farmer.
"Don't know," replied the farmer. "We haven't been able to catch
one yet."
