RDMA: Add and use rdma_for_each_port

2019-02-19T17:13:39Z

We have many loops iterating over all of the end port numbers on a struct ib_device, simplify them with a for_each helper. Reviewed-by: Parav Pandit Signed-off-by: Jason Gunthorpe

RDMA/core: Move device addition deletion to device.c

2019-02-16T04:57:14Z

Move core device addition and removal from sysfs.c to device.c as device.c is more appropriate place for device management. Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/core: Introduce and use ib_setup_port_attrs()

2019-02-16T04:52:17Z

Refactor code for device and port sysfs attributes for reuse. While at it, rename counter part free function to ib_free_port_attrs. Also attribute setup sequence is: (a) port specific init. (b) device stats alloc/init. So for cleanup, follow reverse sequence: (a) device stats dealloc (b) port specific cleanup Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/core: Use simpler device_del() instead of device_unregister()

2019-02-16T04:42:02Z

Instead of holding extra reference using get_device() that device_unregister() releases, simplify it as below. device_add() balances with device_del(). device_initialize() balances with put_device(), always via ib_dealloc_device().

RDMA: Introduce and use rdma_device_to_ibdev()

2019-01-14T20:12:03Z

Introduce and use rdma_device_to_ibdev() API for those drivers which are registering one sysfs group and also use in ib_core. In subsequent patch, device->provider_ibdev one-to-one mapping is no longer holds true during accessing sysfs entries. Therefore, introduce an API rdma_device_to_ibdev() that provides such information. Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA: Rename port_callback to init_port

2019-01-14T20:05:14Z

Most provider routines are callback routines which ib core invokes. _callback suffix doesn't convey information about when such callback is invoked. Therefore, rename port_callback to init_port. Additionally, store the init_port function pointer in ib_device_ops, so that it can be accessed in subsequent patches when binding rdma device to net namespace.

RDMA: Start use ib_device_ops

2018-12-12T14:40:16Z

Make all the required change to start use the ib_device_ops structure. Signed-off-by: Kamal Heib Signed-off-by: Jason Gunthorpe

RDMA/core: Fix comment for hw stats init for port == 0

2018-10-17T15:43:07Z

When add_port() is done for port == 0, it indicates that ports hardware counters initialization should be skipped. Reflect so in the comment. Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky Signed-off-by: Doug Ledford

RDMA/core: Rename ports_parent to ports_kobj

2018-10-16T18:09:45Z

Normally kobj objects have kobj suffix to reflect it. Rename ports_parent to ports_kobj. Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky Signed-off-by: Doug Ledford

RDMA/core: Do not expose unsupported counters

2018-10-16T18:09:44Z

If the provider driver (such as rdma_rxe) doesn't support pma counters, avoid exposing its directory similar to optional hw_counters directory. If core fails to read the PMA counter, return an error so that user can retry later if needed.
