6910e366 - RDMA/mlx5: Introduce the 'data direct' driver

Thu, 01 Aug 2024 12:05:11 +0000

RDMA/mlx5: Introduce the 'data direct' driverIntroduce the 'data direct' driver for a ConnectX-8 Data Direct device.The 'data direct' driver functions as the affiliated DMA device for oneor more capable mlx5_ib devices. This DMA device, as the name suggests,is used exclusively for DMA operations. It can be considered a DMA enginemanaged by a PF/VF, lacking network capabilities and having minimal overallcapabilities.Consequently, the DMA NIC PF will not be exposed to or directly used bysoftware applications. The driver will not have any direct interface orinteraction with the firmware (no command interface, no capabilities,etc.). It will operate solely over PCI to enable its DMA functionality.Registration and un-registration of the driver are handled as part ofthe mlx5_ib initialization and exit processes, as the mlx5_ib deviceswill effectively be its clients.The driver will serve as the DMA device for accessing another PCI deviceto achieve optimal performance (both on the same NUMA node, P2P access,etc.).Upon probing, it will read its VUID over PCI to handle mlx5_ib deviceregistrations with the same VUID.Upon removal, it will notify its clients to allow them to clean up theresources that were mmaped with its DMA device.Signed-off-by: Yishai Hadas Link: https://patch.msgid.link/b77edecfd476c3f445da96ab6aef499ae47b2829.1722512548.git.leon@kernel.orgSigned-off-by: Leon Romanovsky List of files: /linux-6.15/drivers/infiniband/hw/mlx5/Makefile

758ce14a - RDMA/mlx5: Implement MACsec gid addition and deletion

Tue, 03 May 2022 05:37:48 +0000

RDMA/mlx5: Implement MACsec gid addition and deletionHandle MACsec IP ambiguity issue, since mlx5 hw can't supportprogramming both the MACsec and the physical gid when they have the sameIP address, because it wouldn't know to whom to steer the traffic.Hence in such case we delete the physical gid from the hw gid table,which would then cause all traffic sent over it to fail, and we'll onlybe able to send traffic over the MACsec gid.Signed-off-by: Patrisious Haddad Reviewed-by: Raed Salem Reviewed-by: Mark Zhang Signed-off-by: Leon Romanovsky List of files: /linux-6.15/drivers/infiniband/hw/mlx5/Makefile
