net/mlx5: Add Fast teardown support

2018-10-03T23:18:00+00:00

Today mlx5 devices support two teardown modes: 1- Regular teardown 2- Force teardown This change introduces the enhanced version of the "Force teardown" that allows SW to perform teardown in a faster way without the need to reclaim all the pages. Fast teardown provides the following advantages: 1- Fix a FW race condition that could cause command timeout 2- Avoid moving to polling mode 3- Close the vport to prevent PCI ACK to be sent without been scatter to memory Signed-off-by: Feras Daoud Reviewed-by: Majd Dibbiny Signed-off-by: Saeed Mahameed

net/mlx5: Add proper NIC TX steering flow tables support

2018-09-05T04:56:33+00:00

Extend the ability to add steering rules to NIC TX flow tables. For now, we are only adding TX bypass (egress) which is used by the RDMA side. This will allow to shape outgoing traffic and tweak it if needed, for example performing encapsulation or rewriting headers.

net/mlx5: Rename modify/query_vport state related enums

2018-08-09T02:34:54+00:00

Modify and query vport state commands share the same admin_state and op_mod values, rename the enums to fit them both. In addition, remove the esw prefix from the admin state enum as this also applied for vnic. Signed-off-by: Eran Ben Elisha Signed-off-by: Saeed Mahameed Signed-off-by: David S. Miller

net/mlx5: FW tracer, events handling

2018-07-23T22:01:11+00:00

The tracer has one event, event 0x26, with two subtypes: - Subtype 0: Ownership change - Subtype 1: Traces available An ownership change occurs in the following cases: 1- Owner releases his ownership, in this case, an event will be sent to inform others to reattempt acquire ownership. 2- Ownership was taken by a higher priority tool, in this case the owner should understand that it lost ownership, and go through tear down flow. The second subtype indicates that there are traces in the trace buffer, in this case, the driver polls the tracer buffer for new traces, parse them and prepares the messages for printing. The HW starts tracing from the first address in the tracer buffer. Driver receives an event notifying that new trace block exists. HW posts a timestamp event at the last 8B of every 256B block. Comparing the timestamp to the last handled timestamp would indicate that this is a new trace block. Once the new timestamp is detected, the entire block is considered valid. Block validation and parsing, should be done after copying the current block to a different location, in order to avoid block overwritten during processing.

Pull rdma updates from Jason Gunthorpe: "This has been a quiet cycle for RDMA, the big bulk is the usual smallish driver updates and bug fixes. About four new uAPI related things. Not as much Szykaller patches this time, the bugs it finds are getting harder to fix. Summary: - More work cleaning up the RDMA CM code - Usual driver bug fixes and cleanups for qedr, qib, hfi1, hns, i40iw, iw_cxgb4, mlx5, rxe - Driver specific resource tracking and reporting via netlink - Continued work for name space support from Parav - MPLS support for the verbs flow steering uAPI - A few tricky IPoIB fixes improving robustness - HFI1 driver support for the '16B' management packet format - Some auditing to not print kernel pointers via %llx or similar - Mark the entire 'UCM' user-space interface as BROKEN with the intent to remove it entirely. The user space side of this was long ago replaced with RDMA-CM and syzkaller is finding bugs in the residual UCM interface nobody wishes to fix because nobody uses it. - Purge more bogus BUG_ON's from Leon - 'flow counters' verbs uAPI - T10 fixups for iser/isert, these are Acked by Martin but going through the RDMA tree due to dependencies" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (138 commits) RDMA/mlx5: Update SPDX tags to show proper license RDMA/restrack: Change SPDX tag to properly reflect license IB/hfi1: Fix comment on default hdr entry size IB/hfi1: Rename exp_lock to exp_mutex IB/hfi1: Add bypass register defines and replace blind constants IB/hfi1: Remove unused variable IB/hfi1: Ensure VL index is within bounds IB/hfi1: Fix user context tail allocation for DMA_RTAIL IB/hns: Use zeroing memory allocator instead of allocator/memset infiniband: fix a possible use-after-free bug iw_cxgb4: add INFINIBAND_ADDR_TRANS dependency IB/isert: use T10-PI check mask definitions from core layer IB/iser: use T10-PI check mask definitions from core layer RDMA/core: introduce check masks for T10-PI offload IB/isert: fix T10-pi check mask setting IB/mlx5: Add counters read support IB/mlx5: Add flow counters read support IB/mlx5: Add flow counters binding support IB/mlx5: Add counters create and destroy support IB/uverbs: Add support for flow counters ...

net/mlx5: Add FPGA QP error event
