8700e3e7 - Soft RoCE driver

Thu, 16 Jun 2016 13:45:23 +0000

Soft RoCE driverSoft RoCE (RXE) - The software RoCE driverib_rxe implements the RDMA transport and registers to the RDMA coredevice as a kernel verbs provider. It also implements the packet IOlayer. On the other hand ib_rxe registers to the Linux netdev stackas a udp encapsulating protocol, in that case RDMA, for sending andreceiving packets over any Ethernet device. This yields a RDMAtransport over the UDP/Ethernet network layer forming a RoCEv2compatible device.The configuration procedure of the Soft RoCE drivers requiresbinding to any existing Ethernet network device. This is done with/sys interface.A userspace Soft RoCE library (librxe) provides user applicationsthe ability to run with Soft RoCE devices. The use of rxe verbs insuser space requires the inclusion of librxe as a device specificsplug-in to libibverbs. librxe is packaged separately.Architecture: +-----------------------------------------------------------+ | Application | +-----------------------------------------------------------+ +-----------------------------------+ | libibverbs |User +-----------------------------------+ +----------------+ +----------------+ | librxe | | HW RoCE lib | +----------------+ +----------------++---------------------------------------------------------------+ +--------------+ +------------+ | Sockets | | RDMA ULP | +--------------+ +------------+ +--------------+ +---------------------+ | TCP/IP | | ib_core | +--------------+ +---------------------+ +------------+ +----------------+Kernel | ib_rxe | | HW RoCE driver | +------------+ +----------------+ +------------------------------------+ | NIC driver | +------------------------------------+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +-----------------------------------------------------------+ | Application | +-----------------------------------------------------------+ +-----------------------------------+ | libibverbs |User +-----------------------------------+ +----------------+ +----------------+ | librxe | | HW RoCE lib | +----------------+ +----------------+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +--------------+ +------------+ | Sockets | | RDMA ULP | +--------------+ +------------+ +--------------+ +---------------------+ | TCP/IP | | ib_core | +--------------+ +---------------------+ +------------+ +----------------+Kernel | ib_rxe | | HW RoCE driver | +------------+ +----------------+ +------------------------------------+ | NIC driver | +------------------------------------+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Soft RoCE resources:[1[ https://github.com/SoftRoCE/librxe-dev librxe - source code inGithub[2] https://github.com/SoftRoCE/rxe-dev/wiki/rxe-dev:-Home - Soft RoCEWiki page[3] https://github.com/SoftRoCE/librxe-dev - Soft RoCE userspace librarySigned-off-by: Kamal Heib Signed-off-by: Amir Vadai Signed-off-by: Moni Shoua Reviewed-by: Haggai Eran Signed-off-by: Doug Ledford List of files: /linux-6.15/drivers/infiniband/sw/Makefile

0194621b - IB/rdmavt: Create module framework and handle driver registration

Wed, 06 Jan 2016 17:50:24 +0000

IB/rdmavt: Create module framework and handle driver registrationThis patch introduces the basics for a new module called rdma_vt. This newdriver is a software implementation of the InfiniBand verbs and aims toreplace the multiple implementations that exist and duplicate each others'code.While the call to actually register the device with the IB core happens inrdma_vt, most of the work is still done in the drivers themselves. Thiswill be changing in a follow on patch this is just laying the groundworkfor this infrastructure.Reviewed-by: Ira Weiny Reviewed-by: Mike Marciniszyn Signed-off-by: Dennis Dalessandro Signed-off-by: Doug Ledford List of files: /linux-6.15/drivers/infiniband/sw/Makefile
