IB/core: Allow device-specific per-port sysfs files

2010-05-21T17:34:44Z

Add a new parameter to ib_register_device() so that low-level device drivers can pass in a pointer to a callback function that will be called for each port that is registered in sysfs. This allows low-level device drivers to create files in /sys/class/infiniband//ports// without having to poke through the internals of the RDMA sysfs handling. There is no need for an unregister function since the kobject reference will go to zero when ib_unregister_device() is called. Signed-off-by: Ralph Campbell Signed-off-by: Roland Dreier

Driver core: Constify struct sysfs_ops in struct kobj_type

2010-03-08T01:04:49Z

Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy Acked-by: David Teigland Acked-by: Matt Domsch Acked-by: Maciej Sosnowski Acked-by: Hans J.

infiniband: remove driver_data direct access of struct device

2009-06-16T04:30:26Z

In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

IB: Remove useless ibdev_is_alive() tests from sysfs code

2009-03-04T23:22:39Z

Some attribute show functions test ibdev_is_alive() to make sure that it's OK to access device state. However, the sysfs attributes will not be registered until the device is fully initialized, and they'll be unregistered before anything is torn down, so ibdev_is_alive() doesn't do anything useful. Remove it. Signed-off-by: Roland Dreier

IB: Remove sysfs files before unregistering device

2009-02-25T21:27:46Z

Move the ib_device_unregister_sysfs() call from ib_dealloc_device() to ib_unregister_device(). The old code allows device unregister to proceed even if some sysfs files are open, which leaves a window where userspace can open a file before a device is removed but then end up reading the file after the device is removed, which leads to various kernel crashes either because the device data structure is freed or because the low-level driver code is gone after module removal. By not returning from ib_unregister_device() until after all sysfs entries are removed, we make sure that data structures and/or module code is not freed until after all sysfs access is done.

RDMA/core: Add iWARP protocol statistics attributes in sysfs

2008-07-15T06:48:48Z

This patch adds a sysfs attribute group called "proto_stats" under /sys/class/infiniband/$device/ and populates this group with protocol statistics if they exist for a given device. Currently, only iWARP stats are defined, but the code is designed to allow InfiniBand protocol stats if they become available. These stats are per-device and more importantly -not- per port. Details: - Add union rdma_protocol_stats in ib_verbs.h. This union allows defining transport-specific stats. Currently only iwarp stats are defined. - Add struct iw_protocol_stats to define the current set of iwarp protocol stats. - Add new ib_device method called get_proto_stats() to return protocol statistics. - Add logic in core/sysfs.c to create iwarp protocol stats attributes if the device is an RNIC and has a get_proto_stats() method.
