net/mlx5e: Add a lock on tir list

2019-04-17T06:39:40+00:00

[ Upstream commit 80a2a9026b24c6bd34b8d58256973e22270bedec ] Refresh tirs is looping over a global list of tirs while netdevs are adding and removing tirs from that list. That is why a lock is required. Fixes: 724b2aa15126 ("net/mlx5e: TIRs management refactoring") Signed-off-by: Yuval Avnery Signed-off-by: Saeed Mahameed Signed-off-by: Sasha Levin

Pull rdma updates from Jason Gunthorpe: "This has been a fairly typical cycle, with the usual sorts of driver updates. Several series continue to come through which improve and modernize various parts of the core code, and we finally are starting to get the uAPI command interface cleaned up. - Various driver fixes for bnxt_re, cxgb3/4, hfi1, hns, i40iw, mlx4, mlx5, qib, rxe, usnic - Rework the entire syscall flow for uverbs to be able to run over ioctl(). Finally getting past the historic bad choice to use write() for command execution - More functional coverage with the mlx5 'devx' user API - Start of the HFI1 series for 'TID RDMA' - SRQ support in the hns driver - Support for new IBTA defined 2x lane widths - A big series to consolidate all the driver function pointers into a big struct and have drivers provide a 'static const' version of the struct instead of open coding initialization - New 'advise_mr' uAPI to control device caching/loading of page tables - Support for inline data in SRPT - Modernize how umad uses the driver core and creates cdev's and sysfs files - First steps toward removing 'uobject' from the view of the drivers" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (193 commits) RDMA/srpt: Use kmem_cache_free() instead of kfree() RDMA/mlx5: Signedness bug in UVERBS_HANDLER() IB/uverbs: Signedness bug in UVERBS_HANDLER() IB/mlx5: Allocate the per-port Q counter shared when DEVX is supported IB/umad: Start using dev_groups of class IB/umad: Use class_groups and let core create class file IB/umad: Refactor code to use cdev_device_add() IB/umad: Avoid destroying device while it is accessed IB/umad: Simplify and avoid dynamic allocation of class IB/mlx5: Fix wrong error unwind IB/mlx4: Remove set but not used variable 'pd' RDMA/iwcm: Don't copy past the end of dev_name() string IB/mlx5: Fix long EEH recover time with NVMe offloads IB/mlx5: Simplify netdev unbinding IB/core: Move query port to ioctl RDMA/nldev: Expose port_cap_flags2 IB/core: uverbs copy to struct or zero helper IB/rxe: Reuse code which sets port state IB/rxe: Make counters thread safe IB/mlx5: Use the correct commands for UMEM and UCTX allocation ...

net/mlx5: Make RoCE and SR-IOV LAG modes explicit

2018-12-14T21:28:55+00:00

With the introduction of SR-IOV LAG, checking whether LAG is active is no longer good enough, since RoCE and SR-IOV LAG each entails different behavior by both the core and infiniband drivers. This patch introduces facilities to discern LAG type, in addition to mlx5_lag_is_active(). These are implemented in such a way as to allow more complex mode combinations in the future.

net/mlx5: Introduce inter-device communication mechanism

2018-12-14T21:28:51+00:00

This introduces devcom, a generic mechanism for performing operations on both physical functions of the same Connect-X card. The first user of this API is merged eswitch, which will be introduced in subsequent patches. Signed-off-by: Aviv Heller Signed-off-by: Saeed Mahameed

IB/mlx5: Report CapabilityMask2 in ib_query_port

2018-12-11T20:22:45+00:00

CapabilityMask2 exists when IB_PORT_CAP_MASK2_SUP is set in the original capability mask. In such cases, query its value and report it in query port. Signed-off-by: Michael Guralnik Reviewed-by: Majd Dibbiny Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

This isn't used anywhere across the mlx5 driver stack, remove it. Signed-off-by: Or Gerlitz Reviewed-by: Saeed Mahameed Signed-off-by: Saeed Mahameed

RDMA/mlx5: Initialize SRQ tables on mlx5_ib

2018-12-04T07:25:50+00:00

Transfer initialization and cleanup from mlx5_priv struct of mlx5_core_dev to be part of mlx5_ib_dev. This completes removal of SRQ from mlx5_core. Reviewed-by: Mark Bloch Signed-off-by: Leon Romanovsky

net/mlx5: Move SRQ functions to RDMA part

2018-12-04T07:14:30+00:00

There is no need to keep SRQ which is RDMA object in mlx5_core. In this patch, we partially move the execution code, while next patches will move table initialization/release logic too. Reviewed-by: Mark Bloch Signed-off-by: Leon Romanovsky

net/mlx5: Forward SRQ resource events

2018-11-30T00:40:32+00:00

Allow forwarding of SRQ events to mlx5_core interfaces, e.g. mlx5_ib. Use mlx5_notifier_register/unregister in srq.c in order to allow seamless transition of srq.c to infiniband subsystem. Signed-off-by: Saeed Mahameed
