kernel/linux.git/include/linux/mlx5/driver.h, branch v5.3.5

Merge branch 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux

2019-07-04T20:42:59+00:00

Misc updates from mlx5-next branch: 1) Add the required HW definitions and structures for upcoming TLS support. 2) Add support for MCQI and MCQS hardware registers for fw version query. 3) Added hardware bits and structures definitions for sub-functions 4) Small code cleanup and improvement for PF pci driver. 5) Bluefield (ECPF) updates and refactoring for better E-Switch management on ECPF embedded CPU NIC: 5.1) Consolidate querying eswitch number of VFs 5.2) Register event handler at the correct E-Switch init stage 5.3) Setup PF's inline mode and vlan pop when the ECPF is the E-Swtich manager ( the host PF is basically a VF ). 5.4) Handle Vport UC address changes in switchdev mode. 6) Cleanup the rep and netdev reference when unloading IB rep.

net/mlx5: Introduce and use mlx5_eswitch_get_total_vports()

2019-07-03T19:50:42+00:00

Instead MLX5_TOTAL_VPORTS, use mlx5_eswitch_get_total_vports(). mlx5_eswitch_get_total_vports() in subsequent patch accounts for SF vports as well. Expanding MLX5_TOTAL_VPORTS macro would require exposing SF internals to more generic vport.h header file. Such exposure is not desired. Hence a mlx5_eswitch_get_total_vports() is introduced. Given that mlx5_eswitch_get_total_vports() API wants to work on const mlx5_core_dev*, change its helper functions also to accept const *dev. Signed-off-by: Parav Pandit Signed-off-by: Saeed Mahameed

net/mlx5: Expose the API to register for ANY event

2019-07-03T17:56:29+00:00

Expose the API to register for ANY event, mlx5_ib will be able to use this functionality for its needs. Signed-off-by: Yishai Hadas Acked-by: Saeed Mahameed Signed-off-by: Leon Romanovsky

net/mlx5: Reduce dependency on enabled_vfs counter and num_vfs

2019-07-01T23:40:30+00:00

While enabling SR-IOV, PCI core already checks that if SR-IOV is already enabled, it returns failure error code. Hence, remove such duplicate check from mlx5_core driver. While at it, make mlx5_device_disable_sriov() to perform cleanup of VFs in reverse order of mlx5_device_enable_sriov(). Signed-off-by: Parav Pandit Signed-off-by: Saeed Mahameed

net/mlx5: Rename mlx5_pci_dev_type to mlx5_coredev_type

2019-07-01T23:40:30+00:00

Rename mlx5_pci_dev_type to mlx5_coredev_type to distinguish different mlx5 device types. mlx5_coredev_type represents mlx5_core_dev instance type. Hence keep mlx5_coredev_type in mlx5_core_dev structure. Signed-off-by: Huy Nguyen Signed-off-by: Vu Pham Signed-off-by: Parav Pandit Reviewed-by: Parav Pandit Signed-off-by: Saeed Mahameed

net/mlx5: Added MCQI and MCQS registers' description to ifc

2019-07-01T23:40:30+00:00

Given a fw component index, the MCQI register allows us to query this component's information (e.g. its version and capabilities). Given a fw component index, the MCQS register allows us to query the status of a fw component, including its type and state (e.g. PRESET/IN_USE). It can be used to find the index of a component of a specific type, by sequentially increasing the component index, and querying each time the type of the returned component. If max component index is reached, 'last_index_flag' is set by the HCA. These registers' description was added to query the running and pending fw version of the HCA.

Misc updates from mlx5-next branch: 1) E-Switch vport metadata support for source vport matching 2) Convert mkey_table to XArray 3) Shared IRQs and to use single IRQ for all async EQs Signed-off-by: Saeed Mahameed

net/mlx5: Convert mkey_table to XArray

2019-06-24T23:44:40+00:00

The lock protecting the data structure does not need to be an rwlock. The only read access to the lock is in an error path, and if that's limiting your scalability, you have bigger performance problems. Eliminate mlx5_mkey_table in favour of using the xarray directly. reg_mr_callback must use GFP_ATOMIC for allocating XArray nodes as it may be called in interrupt context. This also fixes a minor bug where SRCU locking was being used on the radix tree read side, when RCU was needed too.

net/mlx5: Report devlink health on FW fatal issues

2019-06-13T20:23:19+00:00

Report devlink health on FW fatal issues via fw_fatal_reporter. The driver recover flow for FW fatal error is now being handled by the devlink health. Having the recovery controlled by devlink health, the user has the ability to cancel the auto-recovery for debug session and run it manually. Call mlx5_enter_error_state() before calling devlink_health_report() to ensure entering device error state even if auto-recovery is off. Signed-off-by: Moshe Shemesh Signed-off-by: Saeed Mahameed

net/mlx5: Add fw fatal devlink_health_reporter

2019-06-13T20:23:19+00:00

Create mlx5_devlink_health_reporter for fw fatal reporter. The fw fatal reporter is added in addition to the fw reporter and implements the recover callback. The point of having two reporters for FW issues, is that we don't want to run FW recover on any issue, but only fatal ones.
