bnxt_en: Add PTP clock APIs, ioctls, and ethtool methods

2021-06-28T20:41:05Z

Add the clock APIs to set/get/adjust the hw clock, and the related ioctls and ethtool methods. v2: Propagate error code from ptp_clock_register(). Add spinlock to serialize access to the timecounter. The timecounter is accessed in process context and the RX datapath. Read the PHC using direct registers.

bnxt_en: add debugfs support for DIM

2018-04-27T18:47:30Z

This adds debugfs support for bnxt_en with the purpose of allowing users to examine the current DIM profile in use for each receive queue. This was instrumental in debugging issues found with DIM and ensuring that the profiles we expect to use are the profiles being used.

bnxt_en: add support for software dynamic interrupt moderation

2018-01-10T20:27:45Z

This implements the changes needed for the bnxt_en driver to add support for dynamic interrupt moderation per ring. This does add additional counters in the receive path, but testing shows that any additional instructions are offset by throughput gain when the default configuration is for low latency.

bnxt: Move generic devlink code to new file

2017-10-21T11:28:39Z

Moving generic devlink code (registration) out of VF-R code into new bnxt_devlink file, in preparation for future work to add additional devlink functionality to bnxt. Signed-off-by: Steve Lin Acked-by: Andy Gospodarek Signed-off-by: David S. Miller

bnxt_en: don't consider building bnxt_tc.o if option not enabled

2017-10-07T02:00:26Z

Instead of zeroing out bnxt_tc.c with a #ifdef foo, instead don't compile the file when the option is not enabled. Now make and the preprocessor do not have to waste time compiling a no-op. Signed-off-by: Jonathan Toppins Acked-by: Michael Chan Signed-off-by: David S. Miller

bnxt_en: bnxt: add TC flower filter offload support

2017-08-28T23:57:10Z

This patch adds support for offloading TC based flow rules and actions for the 'flower' classifier in the bnxt_en driver. It includes logic to parse flow rules and actions received from the TC subsystem, store them and issue the corresponding hwrm_cfa_flow_alloc/free FW cmds. L2/IPv4/IPv6 flows and drop, redir, vlan push/pop actions are supported in this patch. In this patch the hwrm_cfa_flow_xxx routines are just stubs. The code for these routines is introduced in the next patch for easier review. Also, the code to query the TC/flower action stats will be introduced in a subsequent patch.

bnxt_en: add support to enable VF-representors

2017-07-25T00:29:58Z

This patch is a part of a patch-set that introduces support for VF-reps in the bnxt_en driver. The driver registers eswitch mode get/set methods with the devlink interface that allow a user to enable SRIOV switchdev mode. When enabled, the driver registers a VF-rep netdev object for each VF with the stack. This can essentially bring the VFs unders the management perview of the hypervisor and applications such as OVS. The next patch in the series, adds the RX/TX routines and a slim netdev implementation for the VF-reps. Signed-off-by: Sathya Perla Signed-off-by: Michael Chan Signed-off-by: David S. Miller

bnxt_en: Add basic XDP support.

2017-02-07T18:31:00Z

Add basic ndo_xdp support to setup and query program, configure the NIC to run in rx page mode, and support XDP_PASS, XDP_DROP, XDP_ABORTED actions only. v3: Pass modified offset and length to stack for XDP_PASS. Remove Kconfig option. v2: Added trace_xdp_exception() Added dma_syncs. Added XDP headroom support. Signed-off-by: Michael Chan Tested-by: Andy Gospodarek Signed-off-by: David S. Miller

bnxt_en: Add interface to support RDMA driver.

2016-12-07T15:59:26Z

Since the network driver and RDMA driver operate on the same PCI function, we need to create an interface to allow the RDMA driver to share resources with the network driver. 1. Create a new bnxt_en_dev struct which will be returned by bnxt_ulp_probe() upon success. After that, all calls from the RDMA driver to bnxt_en will pass a pointer to this struct. 2. This struct contains additional function pointers to register, request msix, send fw messages, register for async events. 3. If the RDMA driver wants to enable RDMA on the function, it needs to call the function pointer bnxt_register_device(). A ulp_ops structure is passed for RCU protected upcalls from bnxt_en to the RDMA driver. 4. The RDMA driver can call firmware APIs using the bnxt_send_fw_msg() function pointer. 5. 1 stats context is reserved when the RDMA driver registers. MSIX and completion rings are reserved when the RDMA driver calls bnxt_request_msix() function pointer. 6. When the RDMA driver calls bnxt_unregister_device(), all RDMA resources will be cleaned up. v2: Fixed 2 uninitialized variable warnings.
